IMPORTANT NOTE AND PRECAUTIONS
Important
Read and save this Operating Manual carefully before attempting to operate the HF/VHF PT-8000A
transceiver. This manual contains important safety and operating instructions for the transceiver.
Precautions
WARNING HIGH VOLTAGE! NEVER touch an antenna or internal antenna connector during
transmission. This may result in an electrical shock or burn of your skin by high-frequency.
NEVER apply AC to the DC socket on the transceiver rear panel. This will ruin the transceiver and
may cause fire.
NEVER allow any object touch any internal parts or connectors on the rear panel of the
transceiver. This could cause electrical shock and severe injury.
NEVER expose the PT-8000A to precipitation like rain or any liquid nor operate the transceiver in
excessively dusty or very humid environment.
NEVER allow children or any unauthorized persons to operate the transceiver.
AVOID placing and using the transceiver in areas with temperatures below -15°C or above +50°C. If the
environment temperature drops so low that the dew point is undercut, avoid operating before the devices
are dried completely.
AVOID placing the transceiver and the power supply against a wall. This may inhibit proper air circulation
and could cause overheat. Do not cover any air inlets and outlets at top, bottom and rear panel of the
devices.
USE CARE when connecting the transceiver to a linear amplifier. Keep in mind the performance limits or
operating ranges of electrical connectors and interfaces. Set the PT-8000A RF-output level to less than the
linear amplifier’s maximum input level to prevent amplifier damage.
USE CARE when not operating the transceiver with Hilberling T9 microphone. Others may have different
pin assignments and connecting to the transceiver may cause damage to the transceiver and the
microphone.

3 INTRODUCTORY NOTES
3.1 Scope Of Delivery
Examine your PT-8000A for signs of damage during shipping. Should any damage be apparent please
take appropriate measures (contacting your carrier). We recommend to retain all packing material – it
might be used for shipment of the radio.
Listed below are the hardware and all accessories delivered with your PT-8000A. Make sure you have
received and unpacked everything:
3.2 About This Manual
The PT-8000A represents primarily state of the art analog RF-design. However digital signal processing
and microprocessor controlled circuits add to this transceiver in a synergistic way. Hence, features and
functions can be easily improved and/or tailored to customer needs through updating the Hilberling
GmbH firmware using the USB interface (please have a look at Appendix A2).
2
In this manual the following signs and symbols are used:
The STOP sign indicates a warning that must be obeyed for safety reasons.
This sign indicates an important explanation or a specific advice which should be obeyed.
An additional information or explanation is indicated this way.
3.3 Notes On Locating
When selecting the place for operating the PT-8000A bear in mind the general limitation
concerning environmental conditions as outlined in the specifications and the cautions at
the very beginning of this manual (P. ii).
Always handle the PT-8000A with care – consider the weight of more than 50 lbs, please!
Please make sure proper air circulation. Do not cover any air inlets and outlets at top,
bottom and rear panel of the devices.
Choose the place of installation so that all connectors of the PT-8000A are reachable any
time.
Select a power outlet that is capable to handle the power requirements. Connect your PT8000A to a proper ground system – which is important for optimum operation of any HF
transceiver – especially when operating high power by using an external amplifier. In the
past, a ground connection to a copper water pipe was often used for this purpose. Recent
revisions to the National Electric Code has made this practice a code violation. Bear in
mind that modern supply water installations utilize plastic pipe – which do not function
grounding purposes. Never use a gas or electric pipe since the connection could cause an
explosion or electric shock. A good grounding system not only prevents electrical shock but
also helps to ensure trouble free operation and will diminish television and broadcast
interference (TVI/BCI).
For your convenience you might raise the front of PT-8000A and HN-8000 by unfolding and locking tilt
bails mounted at the front equipment feet into front position as shown on Fig. 1 (see next page).
PT-8000A Operating Manual v2.00.33 3
Fig. 1
If a large resistance will complicate the unfolding, please spread the bail easy for hurdle the
locking nib to avoid damage of the equipment foot.
3.4 Antenna Considerations / Antenna Tuner
Standing wave ratio (SWR) may increase significantly when using an antenna outside of the specific
frequency range for which it is tuned. The final power amplifier will operate at peak performance only
when its load is resistive – i.e. the SWR is close to 1.0.
Therefore the PT-8000A is equipped with an automatic antenna tuner (ATU) which does not actually tune
the antenna. The ATU instead matches the feed line to the final amplifiers so they always “see” a SWR
close to 1.0. The ATU has its limits – tuning mismatches with SWR greater than 2.0 become difficult and
will exceed the capabilities of the ATU. Using a tuned or resonant antenna with 50 Ohm impedance at the
feed point for the specific frequencies is highly recommended. The purpose of the ATU is to ensure that a
resonant antenna can be used at the limits of the band selected with optimum performance of both PT8000A and antenna system.
Never try to hook up a symmetrical open feeder line (balanced, twin-lead, ladder line etc.) directly to the
PT-8000A. Instead use 50 ohm coaxial feeders only. The connectors supplied on the PT-8000A are all
Type N.
With the ATU it is acceptable to use a broadband antenna system like a log periodic or T2FD system which
trade wide bandwidth for an SWR ranging as high as 2.0.

5 POWER SUPPLY HN-8000
5.1 General Description
Each PT-8000A is equipped with its power supply HN-8000, which delivers 13.8 V DC @ 8 Amps internal
/ 5 Amps. external and additional 50 V DC @ 14 Amp. max., i.e. the overall performance is about 900
W.
Operating voltages from the mains can be in the range of 90 VAC to 260 VAC without any degradation in
output power. Only the efficiency will vary slightly. It complies with special regulations in some countries
regarding power factor compensation (PFC). The HN-8000 provides triple HF shielding and feedthrough
filters.
In addition the HN-8000 provides an auxiliary output 13.8 VDC @ 5 Amp at the back panel, e.g. to
deliver further shack equipment.

8.6 Pushbuttons with LED Status Display
To inform about the status of several main functions of the
PT-8000A – in addition to display information – some
pushbuttons are equipped with LED, respectively the status
of fundamental operating conditions are indicated by LED.
Status displays as follows:

Fig. 22g
8.7 LED Status Display
The three main modes of PT-8000A (MAIN-RX / SUB-RX / TX) are displayed
with colored LED.
The PT-8000A incorporates a transmitter and two independent receivers
(MAIN RX and SUB-RX). Both receivers are permanently operating. Even if a
receiver is in the background i.e. not fully accessible through all main controls
the receiver is operating with its last settings when it has been the active one.
One transmitter and two receivers are operated in three main modes:
MAIN-RX is active and SUB is working in the background
(green MAIN-RX LED is on)
SUB-RX is active and MAIN is working in the background
(yellow SUB-RX LED is on)
TX is operating (red TX-LED is on)
Note: The MAIN RX VFOs will always determine the transmit (TX) frequencies
and other operating parameters.
Exception Split-Mode: In this case the selected (displayed) SUB-RX-VFO
determines the transmit frequency (see Page 42).
The red LED EXT REF will be on when an external 10 MHz signal is
representing the frequency reference.
The internal 10 MHz system clock no longer takes effect.

9 MAIN- AND SUB-RX OPERATIONS
The PT-8000A incorporates a transmitter and two independent receivers
(MAIN-RX and SUB-RX). Both receivers are permanently operating. Even if a
receiver is in the background i.e. not fully accessible through all main controls
the receiver is operating with its last settings when it has been the active one.
Using MAIN- and SUB-RX allows duplex operation mode.
Each of the two RX provides again two VFO: VFO A and VFO B. The active
VFO is called selected VFO, the other is called VFO in standby (s. P. 40).
Two controls are doubled, hence for these functions MAIN-/SUB-RX are
always accessible regardless of their status active or stand-by:
1. The selected VFO of the active RX (usually MAIN-RX) is always accessible
through MAIN tuning knob. The selected VFO of the RX working in the
background (usually SUB RX) is always accessible through SUB VFO knob.
2. The volume of MAIN- and SUB-RX is permanently adjustable through the
respective controls MAIN und SUB.
Both knobs have a push function:
Pushing MAIN will turn off PT-8000A speaker, pushing SUB will turn off
HN-8000 speaker. (see also Page 53).
The push button MAIN/SUB (located in the cluster MODE) toggles between
the two RX changing their status active or background.
After power on the PT-8000A the MAIN-RX is the active one (corresponding
SUB-RX is working in the background).
LED MAIN-RX and LED SUB-RX indicate which RX is the active one and so
which is accessible through all knobs and buttons on the front panel.
In the upper left corner the display shows the label of the active one
(MAIN or SUB).
Frequency, mode, filter bandwidths and S-meters are displayed for MAIN
and SUB respectively (see Figure 24).
Activation of noise reduction (NR), noise blanker (NB), DSP Filter, DSP-
Notch, IF-Notch, preamplifier, preselector and the squelch marker are
displayed for the active RX exclusively.
which is in the
PT-8000A Operating Manual v2.00.33 21
Example
When toggling between MAIN- and SUB-RX the actual settings of the controls
used at last are not transferred to the new active RX – instead the former
settings of this RX are the actual one – until they are overwritten by the
respective control.
The squelch threshold set to the RX working in the background will stay the
actual one when this RX becomes the active – until one touches the squelch
control to set the threshold to a new setting.
The large S-meter is always allocated to the active RX. The smaller S-meter is
indicating the field strength of the RX working in the background.
Transmitting (TX) is only possible when MAIN-RX is the active one and SUB-RX
is working in the background.
When transmitting the SUB-RX may be used to monitor own RF-signal.
Receiving with SUB-RX on a separate antenna is limited however: Excessive
field strength may trip the protection circuits. Receiving at frequencies adjacent
to the transmitting frequency may be limited even by the superior dynamic
characteristics of the PT-8000A receivers - which are of course finite.

10.3 DATA Transmission (Digital Operation Modes)
The function DATA enables to send out signals which modulate the transmitter
by using following inputs:
0 dBm IN (microphone socket MIC-PTT pin 4, see Page 7 Tab. 6)
AUDIO DATA IN (J20 AUDIO IN/OUT pin 2, see Page 6 Tab. 4)
This is basically possible with all modes – where appropriate. Thus why it is
called „submode“
When pushing DATA button located in the cluster MODE:
DATA-LED will stay off.
DATA menu will be called up.
In case this softkey is activated (the softkey will be displayed inverse;
DATA-LED will turn on) the signal at the 0dBm input (MIC-PTT Pin 4)
will be transmitted when PTT is switched.
In case this softkey is activated (the softkey will be displayed inverse
as shown here; DATA-LED will turn on) the signal at the AUDIO
DATA IN input (J20 Pin 2+3/10) will be transmitted when PTT is
switched.
In case this softkey is activated (the softkey will be displayed inverse; DATALED will not turn on) the signal at the AUDIO DATA IN input (J20 Pin
2+3/10) will be transmitted when PTT is switched by an external software
command (USB interface).
TX 0dBm, TX DATA and DATA Mike are only working alternatively.
DATA mode may be selected in all operating modes.
Only when DATA mode is selected a PTT signal can be fed through USB
interface (handshake signal).
In case the DATA softkey menu is displayed pushing DATA will only terminate
TX 0dBm or TX DATA modus.
If the menu is not displayed pushing DATA will call it up and a second push
will terminate the aforementioned DATA operations:
DATA-LED will turn off.

11 SELECTING FREQUENCIES
To select or change a frequency different means are available:
Select with band buttons (see below).
Numerical input (see Page 32).
Recall from a memory channel (see Page 34).
11.1 Select with BAND Buttons
Pushing a band pushbutton selects one of two stored
frequencies within the desired band (see Table 13 and 14).
The MF and each HF amateur radio band (excl. 60 m) is
allocated to a pushbutton in the cluster BAND.
The VHF amateur radio bands and the RX-only range from
110 MHz are accessible by the 0 VHF button in the cluster
MODE and additional select in the VHF softkey menu.
Each band button stores two frequencies exclusively for this band. Pressing the
button again will toggle between the last two frequencies used within this
band.
The last used frequency within a band is stored automatically, so the stored
frequency will change continuously when tuning within the band with VFO
knob or STEP-VFO knob.
In case the BAND limits are exceeded trough tuning the last valid frequency
that has been stored will remain. Press button again for return the PT-8000A
to the last used frequency.
The two stored frequencies of a band are correlated to each VFO. Selecting
the alternate VFO will give access to another two frequencies in that band
(which were used with this VFO). Of course this is applicable for both MAINand SUB-RX.
Mode, filter adjustments (width/shift), antenna and tuning increments (STEP
VFO) are stored along with the respective frequency.
A numerical input of a frequency (see Page 32) within the selected band will
overwrite one of the two stored frequencies (the last frequency used).
11.1.1 HF Amateur Radio Bands
Pressing e.g. 14 5 button (located in the cluster BAND) selects the last used
frequency within the 20 m band of the selected VFO.
The VFO menu (see Page 41) will be displayed.
Pressing band key again will toggle between the last two frequencies used
within this band.
Two more frequencies are allocated to the „stand-by“-VFO.

If one of the softkeys (144/50/28) is pushed and held the transverter operation
frequency band is displayed instead of the standby VFO frequency, see Figure
35.
Using control STEP-VFO /
MEM/CH gives access to all
transverter operation frequency
bands as listed below (Table 15).
When releasing the transverter
softkey the new frequency band is
transferred and will be stored.
The following 13 transverter operation frequency bands are available:
When the PT-8000A operates in transverter mode the transmitter output is
directed to the TX-ext. connector on the rear panel (see Page 5 / Table 3 /
socket J14).
A transverter for one of the bands shown in Table 15 must be selected so that it
can operate properly with drive power 10 m, 6 m or 2 m.
Maximum power level at J14 is +20 dBm.
Hooking up multiple transverters requires external distribution of TX signals
from TX-ext. J14.

11.2 Numerical Frequency Input ENTER
Pushing ENTER button located in the cluster MODE will call up the ENTER
menu and will activate the numerical frequency input:
The frequency display will show blanks for all digits. A cursor indicates
(„_“) which digit can be edited.
The number of blanks/digits are shown depends on the resolution selected by
using the Softkeys STEP , STEP or STEP VFO (s. P. 41). E.g. the
resolution is 1 kHz the frequency will be displayed as follows:
Pushing the respective numbers from 1.8 1 to 28 9 allocated to the
BAND buttons (located in the cluster BAND) and 0 VHF (located in the
cluster MODE) will insert the digits from left to right.
Pushing ENTER button (located in the cluster MODE or softkey) again will
complete the input; the RX transfers the frequency; the VFO menu will be
displayed:
Numerical input will be aborted;
the last used frequency will be displayed instead;
the last used softkey menu will be called up.
The curser will jump to the next left position; the last digit input will be deleted;
a leading empty digit will reappear.
Frequency input will be completed;
the RX transfers the frequency (function the same as ENTER key in the cluster
MODE);the VFO softkey menu will be displayed.

Because the numerical input always starts with the 100 MHz digit possibly the
0 VHF button first must be pushed. So this digit disappears and the Cursor
jumps one digit to the right to the 10 MHz digit. These can be deleted as well
by pushing 0 VHF button again, the cursor jumps to the 1 MHz digit, etc.
It is not necessary to key all digits (e.g. “0”). Pushing ENTER after the last digit
will set all lower digits to zero. After a valid numerical input is acknowledged
the frequency will be displayed and the respective RX will operate on that
frequency.
In case the least significant digit is typed in the numerical input is terminated
and the frequency is transferred to the respective VFO (Pushing ENTER is not
required). The RX operates with the new frequency.
In case the input is not acknowledged through ENTER or completely input or
not aborted through ESC, after a period of 10 seconds without any activity the
numerical input will be terminated and the last frequency used will be selected
again. The last used softkey menu will be called up.
If the entered frequency is outside of RX frequency ranges of the PT-8000A the
VFO will jump to the upper border of the next lower RX frequency range. If
input frequency is < 9 kHz it will jump to 9 kHz.
In case the input frequency is a valid BAND frequency one of the two stored
frequencies of this BAND will be overwritten by the numerical input.
In transverter operation two additional digits will be displayed for 1 and 10
gigahertz range:
In this case the 1 Hz digit is not available for numerical input.

11.4 VFO Main Tuning Knob (active RX) and SUB VFO Tuning Knob (RX in the Background)
Primary means of tuning the active RX (MAIN- or SUB-RX) is the VFO Main
Tuning Knob. With a full rotation it generates 512 steps, so that depending on
the chosen tuning increments 512 Hz, 5.12 kHz, 51.2 kHz or 512 kHz can be
run through.
The SUB VFO Tuning Knob generates 256 steps with a full rotation, so that
depending on the chosen tuning increments 256 Hz, 2.56 kHz, 25.6 kHz or
256 kHz can be run through.
General frequency coverage of both RX is 9 kHz to 30 MHz, 50 to 54 MHz,
69.9 MHz to 70.7 MHz and 110 MHz to 148 MHz. Due to the frequency
scheme of the PT-8000A the ranges between them are blanked out.
Transmit operation is only possible on the allocated amateur radio bands of
that IARU region in which one the TRX will operate after delivery (see Page 28 /
Table 13 and 14).
In case the transmit boundaries are to be modified (commercial application;
signal generator operation; new amateur radio frequencies) please contact
Hilberling GmbH for further information about a software update.
The tuning increments of the VFO are adjustable through STEP selection, which
is allocated to the VFO softkey menu.
If the VFO menu is not displayed, push button VFO A/B (see Page 40).
Softkey STEP (towards fine tuning) decreases the tuning increments by
power of 10. Additional digits appear at the VFO frequency readout.
Softkey STEP (towards coarse tuning) increases the tuning increments by
power of 10. Lesser digits appear at the VFO frequency readout.
Selectable increments are 1 Hz / 10 Hz / 100 Hz / 1 kHz.
Digits below the selected tuning width are set to 0 and will be displayed in dark
grey.
PT-8000A Operating Manual v2.00.33 39
Fig. 48
Fig. 47
Each mode has been allocated a default tuning increment setting:
FM: 100 Hz
SSB / CW / AM: 10 Hz
Changing the operating mode will reset the current setting to default values.
11.5 STEP-VFO Control
Operation with knob STEP-VFO allows VFO tuning with further increments.
The STEP-VFO Control is placed in the cluster MODE. The control enables
tuning in 10 kHz, 100 kHz and 1 MHz increments.
Pushing the knob activates the STEP-VFO function:
A cursor appears at the 100 kHz digit of the frequency display:
Turning the knob will now tune the VFO by 100 kHz steps.
Pushing the knob a second time will move the cursor to the 10 kHz digit.
Turning the knob will result in tuning the VFO by 10 kHz steps.
Pushing the knob a third time will move the cursor to the 1 MHz digit –
hence tuning can now be established by 1 MHz steps.
Pushing the knob again will result in a movement of the curser again to
the 100 kHz digit, then 1 kHz, 1 MHz, and so on.
Neither pushing the knob nor turning the control for more than 3 seconds will
terminate the STEP-VFO function. If re-activated by pushing the knob the cursor
will appear at the last used position.
When power up the PT-8000A and STEP-VFO will be activated the curser will
initially occur at the 100 kHz position.

11.6 VFO Management
Both receivers (MAIN- and SUB-RX) have its own two VFOs –
VFO A and VFO B. Switching between VFO A and VFO B is
established through VFO A/B pushbutton. The button is located in
the cluster VFO.
In addition to frequencies the VFOs store filter
bandwidth and operation mode.
When pushing VFO A/B:
In case the VFO softkey menu is already displayed the active RX will
change its VFO (A⇨B or B⇨A).
If a different softkey menu is displayed the first push will call up the VFO
menu. The second push will alter the VFO A and VFO B.
Both frequencies displayed for the active RX will alter its
position. The white display always shows the selected
VFO. The VFO can be identified through the red
nominators A respectively B.
The smaller green display always shows the alternate VFO
that is in standby mode.
Only the SUB-RXs selected VFO frequency is displayed without its identifier A or
B.

11.7 SPLIT Operation
The VFO SPLIT operation in the PT-8000A is realized by using the MAIN and
the SUB-RX. The selected VFO from the MAIN-RX determines the RX frequency,
the selected VFO from the SUB-RX determines the TX frequency.
To enable the VFO SPLIT operation, the MAIN-RX must be the active RX and
the SUB-RX operates in the background.
The PT-8000A stays in the current operation mode of the MAIN-RX when
transmitting, even though there is selected a different mode in the SUB-RX.
Only the frequency of the SUB-RX will be used.
Procedure:
Tune with the active VFO from the MAIN-RX to the desired receive
frequency.
Tune with the active VFO from the SUB-RX to the desired transmit
frequency.
When pushing SPLIT softkey (VFO menu):
When pushing PTT, the desired frequency from the SUB-RX will be used for
transmit instead the receive frequency of the MAIN-RX.
To the left of the Display, below operation mode indicator, SPLIT will be
displayed
The softkey will be displayed inverse
Pushing SPLIT again will terminate VFO SPLIT operation.

12 FILTER BANDWIDTH AND SHIFT FUNCTION FILTER WIDTH / SHIFT
Filtering in the PT-8000A is obtained in the 1st IF @ 40.7 MHz with a 6-pol.
Filter and in the 2nd IF (IF-2) @ 10.7 MHz with an "IM3 Protector" said prefilter
with bandwidth 0.5 kHz, 3 kHz and 15 kHz.
Prefilters are selected automatically depending on operation mode (default
filter; manual filter selection see Pages 59 and 61)
After passing through the 16-pol. quartz filter ladder the channel selection can
be further enhanced by Digital Signal Processing (DSP) working in the audio
range.
The DSP performs the following tasks:
Interpolation between analogue filter bandwidths @ 10.7 MHz.
Slope increase of the filter flanks @ 10.7 MHz and elimination of effects
of group delays by the filters.
Shift the placement of the filters (SHIFT function respective band-pass
tuning).
Activating DSP filtering is accomplished by the pushbutton FILTER located in
the cluster DSP (Bandwidth and Shift/Pitch see Page 46 – 12.2).
In case the FILTER LED is off (shown in pic 58) only the analogue (Xtal-) filters
are active. The selected bandwidth is displayed and graphically expressed (see
Page 46 / 12.1).
When pushing FILTER:
The DSP will be activated.
FILTER-LED will be on.
The display will indicate “DSP” operation.
WIDTH and SHIFT control located in the cluster MODE is used to adjust the
filter bandwidth and to shift the passband across the spectrum.
Pushing the knob will toggle between WIDTH and SHIFT function, turning will
select the current value.
For specific feature in CW mode see Page 23.
Depending on operation MODE there are analogue filters available which are
interpolated in bandwidth by the DSP (see Page 46).

13 NOTCH FUNCTIONS / NOISE REDUCTION / NOISE BLANKER
13.1 Notch Filter: IF-Notch and DSP Multi Notch
Two notch filters of different type are available in the PT-8000A.
One is working at 1st IF @ 40.7 MHz – it´s the classical type of manual notch
filtering using a Xtal bridge – the IF-NOTCH.
The other one is part of the DSP – it´s an Automatic Multi-Notch Filter
(ANF/MNF) – here called the DSP NOTCH.
IF-NOTCH and DSP-NOTCH may be engaged simultaneously.
Notch filtering is not available in AM and FM. In case NOTCH filtering is
active and modes are changed to AM/FM both NOTCHs will cease operation.
After power on both NOTCH filters are off.
13.1.1 IF-NOTCH Filter
The IF-NOTCH will
be activated by
pushing the control
IF-NOTCH which is
located as depicted:
On the display it is outlined as NOTCH 2.
Turning IF-NOTCH will adjust the variable notch through the passband hence
the interference will be almost nullified.
13.1.2 DSP Multi NOTCH Filter („digital“ MNF)
Pushing the NOTCH button located in
the cluster DSP will activate the
automatic multi-notch filtering
(ANF/MNF):
On the display the DSP NOTCH is outlined as NOTCH 1.

14 SQUELCH SQL
The SQUELCH (SQ) is activated by default and will be
affected by the control SQL which is located as depicted.
The threshold for squelch operation is adjusted by turning
the knob.
Once the SQL is activated and the threshold has
engaged i.e. the RX is silent, push and hold the SQL to
override the threshold momentarily.

15 RX GAIN CONTROL AGC / RF-GAIN
15.1 Automatic Gain Control AGC
The AGC (Automatic Gain Control) is active after power on. Its hang time is
1 second (factory default value). Manual control of the AGC system is initiated
through the AGC pushbutton. The hang time can be modified. When PT8000A is powered off the modified hang time is stored.
Deselect AGC by pushing the Knob RF (see Page 51)
Pushing AGC located in the cluster FUNCTION will call up the AGC menu:
Select AGC hang time 3 s; the softkey will be displayed inverse.
Select AGC hang time 2 s; the softkey will be displayed inverse.
Select AGC hang time 1 s (default value); the softkey will be displayed inverse
(as shown here).
Select AGC hang time 500 ms; the softkey will be displayed inverse.
Select AGC hang time 100 ms; the softkey will be displayed inverse.
CW Mode only: Toggles between RF-AGC (default value) und Audio-AGC
(see annotation below)
When pushing AGC the LED will not turn on! It is only switched on when AGC
is deselected by pushing knob RF (see next Page).
To prevent missing of weak signals during tuning the MAIN- or SUB-RX the
AGC hang time will be set to 100 ms automatically.
The AGC-voltage is derived from the RF-signal after it has passed the channel
filters (10.7 MHz). The DSP will narrow the passband – hence out of (DSP)filter signals may still derive AGC voltage. This can be annoying especially
during CW operation. The solution is to switch to Audio-AGC.
AGC is derived from the audio to overcome situations described above. This is
recommended in CW operation with small bandwidths because narrowest Xtal
filter is 500 Hz. Normal operation is RF-AGC.

pushing (AGC off) and to adjust an RF threshold by
turning.
Turning the control RF will adjust the AGC threshold to a level which can be
monitored by observing the S-Meter (active RX). The AGC threshold can be
raised to a certain level where signals below are significantly less audible than
signals above the threshold where AGC action will level out the audio
Pushing the RF control:
Any AGC action will cut off.
AGC-LED located in the cluster FUNCTION will be on.
S-Meter will possibly fall back to zero.
Caution: In case a signal is present the audio volume may exceed the comfort

A1.6.1 Program Window
The program window is structured in three areas.
In the upper area (I) options are accessible for Automarker, Marker and Peak
Hold (see chapter A1.6.2 and A1.6.3), as well as for scaling of signal level
and panorama width (see chapter A1.6.6); below, the areas are arranged for
the panorama display of MAIN-RX/TX (II) and SUB-RX (III).
A vertical red line in the middle of both display areas depicts the center
frequency of the panorama display and therefore it represents the current
frequency of the PT-8000A. Right of center line is shown the frequency range
above the PT-8000A frequency, left of it appropriate the frequency range
below.
A1.6.2 Automarker and Marker
The Automarker (light blue circular ring) indicates the strongest signal within
the current panorama width, for each MAIN- and SUB-RX.
The strength of this signal and the frequency shifting against center frequency
are displayed in the upper left corner of the relative display area using a light
blue font (Fig. A1- 4b).
Automarker is activated each time the program was started and can be deactivated by clicking Automarker (Fig. A1- 4c).
The Marker (light green circular ring) can be used for indication of strength
and frequency of any desired signal in the panorama.
The strength of this signal and the frequency shifting against center frequency
are displayed in the upper right corner of the relative display area using a light
green font (Fig. A1- 5b).

Error Messages
A2.9 Update of MAIN-CPU
Pushing MAIN Update softkey (SOFTWARE menu; Fig. A2- 16/17) will start the
update process for the MAIN-CPU.
The display will show the boot loader screen with a prompt
to start the update program on the connected PC.
If the update procedure should not be further
continued at this point, the PT-8000A is set back
to the normal mode by turning off (POWER) and
restart (after a wait of about 10 seconds).
The PT-8000A is now ready to update, and the program transfer can begin.
Requirements for a successful program transfer are:
1. PT-8000A and PC are connected via USB cable (A2.6).
2. The update program has been started, a COM port is connected and
the new operation program (update file) is loaded (A2.7).
3. The PT-8000A is ready to update (A2.8).
4. The Update standby mode of the PT-8000A and the loaded operating
program agree respecting the CPU (MAIN-CPU).
Click the Start button in the main window of the update program.
The adjacent message box prompts you to set the PT-8000A
ready to update.
This is already done, so click OK (Otherwise please catch up
before clicking, see chapter A2.8).
If a connection error is occurred (e.g. PT-8000A is not ready to update), the
adjacent message box will be shown (Fig. A2- 20).
Check the correct connection of PT-8000A and PC (by the supplied USB data
cable).

Warning Notice
Does the new operation program loaded in the PC not match to the selected
CPU of the PT-8000A, this is pointed out with an error message box
(Fig. A2- 21).
Note that the selected CPU of the PT-8000A matches to the operation
program loaded in the PCs update program (letters M, R and K are prefixed to
the version number).
Now the update program compares the version numbers of the current and
the new operation program. Depending on the outcome different messages
are shown on the PT-8000A display and PC message boxes.
In case the new operation program has a higher version
number than the current version on PT-8000A, the display will
show these numbers in the lower area.
On the PC a message box prompts you to start the program transfer.
Click OK to start the program transfer.
In case the new operation program has the same version
number as the current version on PT-8000A, the display will
show a warning notice and in the lower area these
(identical) numbers.
If the update procedure should not be further
continued at this point, the PT-8000A is set back
to the normal mode by turning off (POWER) and
restart (after a wait of about 10 seconds).
On the PC, a message box will show a warning notice that the new
program version number is identical to the current version.
The message box prompts you to start or abort the program transfer.
Click OK to start the program transfer.
By clicking Cancel, the program transfer will not performed.

If the prompt in the message boxes (Fig. A2- 23/25) has been
answered with OK, the display will show the amount of data to be
transferred in bytes.
Now, the data transfer will be prepared by memory erasing.
The display will show the erasing of memory sectors 1 ... 15.
The update program will show an appropriate notice:
When erasing is complete, the data transfer starts.
Now the display of the PT-8000A will show the total
number of bytes to be transferred and the state of the bytes
current transferred.
In the PC update
program the field
Bytes sent and the
blue progress bar
also will show the
state of the transfer.
It is: Total Bytes = Data Length (entire amount of data to be
transferred)
Prog. Bytes = Bytes Sent (amount of data transferred by now)
When the data transfer is complete, on the display of the
PT-8000A the message Application startup will point out
the automatic restart of the transceiver after a short
waiting period.
