GENERAL DESCRIPTION
The etón E1 is a microprocessor controlled, synthesized,
world band receiver with continuous coverage capability
from 100 kHz through 30 MHz and from 76 MHz
through 108 MHz which includes the AM broadcast and
shortwave bands as well as the FM broadcast band.
The receiver offers excellent sensitivity,selectivity,
dynamic range, and features that permit easy tuning of
desired stations. Conveniently located front panel controls allow for rapid operator programming and ease of
use.The units can be operated from either the supplied
AC ADAPTER,an external 7 to 14 VDC source, or from
four "D" cell batteries (not supplied) for portable operation. A low battery voltage indication is displayed when
that condition exists.
Three electronically switched IF filters are provided to
provide optimum interference rejection for each mode.
The front panel dot matrix liquid crystal display provides
feedback of the current status of the receiver. The seven
digit frequency display provides resolution to 10 Hz in
the AM broadcast and Shortwave bands. Resolution to
20 kHz is displayed in the FM broadcast band.
Backlighting of the display is selectable by a “LIGHT”
key on top of the cabinet.To prolong battery life with
internal battery operation, the backlighting automatically
turns off after a short delay following a function change
or retuning of the receiver unless it is specifically locked
in the ON mode.
When the receiver is turned off, the display provides
either the Local time or Greenwich Mean time (GMT),
selectable in either the off or on state by the user.
Reception modes include Single Sideband (LSB & USB)
and AM in the Shortwave, MW (AM broadcast) and LW
bands. For the LW, Shortwave and MW bands, a selectable sideband synchronous detector (SYNC) allows for
enhanced AM reception by eliminating or reducing distortion due to fading signals or a strong adjacent signal.
During FM broadcast use, stereo reception is available
POWER SUPPLY
C ADAPTER and EXTERNAL DC POWERING
A
The etón E1 receiver is supplied with an AC ADAPTER.
The AC ADAPTER is designed to be plugged into a wall
outlet that supplies AC power, or another source of external filtered DC power between 7 and 12 VDC may be
used.
Connect the output connector of the AC adapter, or other
power source, to the 9 VDC, 1 amp connector on the side
of the receiver.
through the use of headphones, or by connecting the
line out jack to an external stereo system.
Other built-in reception aids include selectable slow,
fast, or automatic AGC time constant, scanning of memory channels, either by time or by carrier presence, passband tuning and squelch as well as treble and bass controls.Two independent, real time clocks provide Local or
GMT time selection. Also provided are a two event
timer, a SLEEP timer, and a SNOOZE mode.
A programmable memory area allows for 1700 independent receiver set up memories.The first 500 of these
memory channels allow names to be attached to the
frequencies and modes stored. The remaining 1200
memory channels allow frequencies to be stored by
country.There are 111 country names factory stored in
this bank of memory with 10 memory channels available
per country and 90 memory channels remaining with no
country assigned. These country names can be modified
or added to by the user. These memories do not require
battery backup and are thus unaffected by power interruptions.
All parameters associated with a particular memory
channel are stored including the frequency, mode, bandwidth, passband tuning setting, fast, slow, or automatic
AGC and synchronous detector state.These memory
channels may be accessed manually or through a time
scan with each channel monitored for a 5 second period, or carrier presence.
If batteries are installed and external power is lost,
the
receiver will continue to operate on battery power even
with the DC plug inserted.
If this occurs
, the receiver will
alert the user with a POWER LOSS indication, and with a
POWER LOSS beep if the POWER LOSS beep feature is
enabled. More details concerning power loss can be

is observed, the batteries are too low for satisfactory
operation and must be replaced.
AC ADAPTER
Keep curtains and other flammable materials out of
direct contact with the AC ADAPTER to avoid overheating.
BATTERY INSTALLATION
The etón E1 receiver is also designed to operate from
four "D” cell batteries (not supplied). NOTE: Check the
batteries periodically for leakage. IF UNIT IS TO BE
STORED OR OTHERWISE NOT USED FOR AN EXTENDED
PERIOD OF TIME, REMOVE THE BATTERIES TO PREVENT
CORROSION AND POSSIBLE DAMAGE TO THE RECEIVER.
Damage caused by battery acid leakage is not covered
under the warranty.
(1) Position the receiver with the front panel towards
you.
(2) Open the battery access door located at the lower
left corner of the front panel. (Shown as #5 in the
front panel drawing.)
(3) Inside you will find an additional door as shown in
the following illustration.
(5) Slide the battery to the right and continue in this
manner until all four batteries are installed. Replace
the inner door and close the outer door.
BATTERY OPERATION
The etón E1 receiver does not rely on the batteries for
retention of memory channels. However, to insure that
clocks are maintained following the loss of AC power
and battery removal, the receiver must first be connected to a source of AC power or have batteries installed.
Clock settings are maintained for a time period of
approximately 10 minutes after all power is removed.
New batteries should be installed before this time period elapses or clock settings will be lost.
BATTERY CONDITION
Battery condition can be observed when the unit is
turned on or if the ‘LIGHT’ button is pressed if no AC
ADAPTER is connected to the receiver. W hen the

used to store the frequency to which the main ‘TUNING’
control is set. Turning the ‘TUNING’ control will change
this frequency.
Pressing ‘TUNE’ transfers the frequency last listened to
while in the MEMORY or COUNTRY modes to the VFO,
along with the current associated function parameters.
This allows for fine tuning of and around the transferred
frequency or modifying its parameters.When ‘TUNE’ is
pressed, “VFO STORED” will briefly appear on the display.This softkey is functional in MEMORY and COUNTRY modes only.
8. < SELECT >
In VFO mode, pressing the ‘<’ or ‘>’ ends of this key will
cause the frequency to increment or decrement in 5 kHz
steps on LF and SW bands, in either 9 or 10 kHz steps
on the MW (AM broadcast) band depending on a menu
setting, and in 100 kHz steps on the FM band.When in
MEMORY or COUNTRY modes, each press of the ‘<’ or
‘>’ ends of the key causes the display to decrement or
increment respectively one memory page.When in
MEMORY or COUNTRY modes, holding down the ‘<’ or

‘TIME’ key was pressed the first time. The receiver displays the time when in the off mode, and when in this
state, pressing the ‘TIME’ key will toggle the displa
between Local and GMT time.
15. PBT
The PBT (PassBand Tuning) knob varies the IF passband
of the receiver plus or minus 2 kHz relative to the detector beat frequency oscillator (BFO) in SSB mode, and relative to the displayed frequency when on AM mode.This
is particularly useful in reducing or eliminating interference to the desired signal from nearby signals.The PBT
knob will be ineffective unless the ‘PBT’ softkey beneath
the display is pressed. The amount of IF frequency displacement from nominal will be displayed directly above
the ‘PBT’ function label on the display.PBT tuning is not
available in FM or AUX modes. In MEMORY or COUNTRY modes, the stored PBT value will always be recalled
and “MEM” will be indicated above the ‘PBT’ softkey
until changed.
16. DX
The ‘DX’ softkey turns on or off an RF preamplifier which
is useful in improving the readability of very weak signals, especially when using the built in telescopic antenna or other short antennas.
When the preamplifier is
enabled, “DX”will appear on the display. When using
long antennas or when the receiver is in close proximity
to very strong broadcast transmitters, the receiver will
perform best with ‘DX’ off. The DX function is not available in AUX mode. Note that battery life will be reduced
somewhat if DX is enabled during portable operation.

key for approximately 2 seconds will lock out the ‘TUNING’ knob and will cause “TUN LOCK” appear on the
display. Depressing the key again for approximately 2
seconds will unlock the ‘TUNING’ knob and “TUN
LOCK” will disappear from the display.
18. Tuning
The 'TUNING' knob is the primary tuning control of the
E1 receiver. In VFO mode, clockwise rotation of the dial
increases frequency and counterclockwise rotation
decreases frequency.The rate at which frequency is
increased or decreased is determined by the band being
tuned and by pressing the ‘FAST/TUNING LOCK’ key on
a given band. In VFO mode, the ‘FAST/TUNING LOCK’
key also changes the displayed frequency resolution. In
MEMORY mode, the ‘TUNING’ knob scrolls through the
500 MEMORY channels one at a time. If the ‘FAST/TUNING LOCK’ key is pressed,“FAST” appears on the display and the ‘TUNING’ control scrolls through the 500
MEMORY channels 10 at a time as long as the ‘TUNING’ knob is being turned. If the ‘TUNING’ knob is not
moved for three seconds, the “FAST” on the display will
disappear and the ‘TUNING’ knob will revert to tuning
MEMORY channels one at a time.
The ‘TUNING’ knob is also used when programming in
MEMORY mode to scroll through all available alphanumeric characters when entering names for each MEMORY entry.
In COUNTRY mode, the ‘TUNING’ knob scrolls through
COUNTRY memory channels one at a time. If the
‘FAST/TUNING LOCK’ key is pressed,“FAST” appears on
the display and the ‘TUNING’ knob scrolls through the
available countries one country at a time with 10 memory channels being available per country.
In SW BAND mode, the ‘TUNING’ control will scroll
through the available shortwave broadcast bands from
120 meters through 11 meters.
19. Mode Softk

illuminate for 10 seconds and then go out. In the ON
state, the display will be lit only briefly following control
inputs. However, holding down the LIGHT key for 3 seconds will override the time out and allow the light to
remain on continuously when the receiver is ON.The user
must keep in mind, however that keeping the light on
continuously when operating on batteries will considerably reduce battery life. More details concerning display
illumination can be found on page 57 under “DISPLAY
LIGHTING”.
3. SNOOZE / SLEEP
When the receiver is OFF, other than in SNOOZE,pushing
this bar will activate the SLEEP timer. This will turn the
receiver ON for the default set time of 15 minutes, after
which it will turn back OFF. To change the set time length
from the default 15 minutes to 1 through 99 minutes,
turn the receiver OFF and rotate the ‘TUNING’ control
after pressing the SNOOZE / SLEEP bar. After setting the
desired SLEEP time, press the bar again to activate SLEEP
mode, or automatic entry will occur in 15 seconds. The
displayed time is always in minutes.When SLEEP mode is
active, a flashing “s XX” will appear in the lower left
hand corner of the display, where “XX” is a number indi-
cating the minutes of SLEEP time remaining.
The following section describes the main display which
will be seen when operating in the VFO mode, This is
the display which the user will see most of the time.
There are several other screens which may appear on
this display under various conditions.These additional
conditions will be covered later.
1. SIGNAL
The signal meter indicates the signal strength of the
incoming signal. The stronger the signal, the more vertical bars appear from left to right across the display.
From 100 through 30,000 kHz, the signal meter is calibrated in S units from 1 thru 9 and in decibels (dB)
above S9 up to +60 dB. On the FM band, the signa
strength is just relative.
