The etón E1 is amicroprocessor 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 7to 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 foreach mode.
The front panel dotmatrix liquid crystal display provides
feedback of the current status ofthe 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 Localtime 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) andLW
bands.For the LW,Shortwave and MW bands, a selec­table sideband synchronous detector (SYNC) allows for
enhancedAM reception by eliminating or reducing dis­tortion due to fading signals or a strong adjacent signal.
During FM broadcast use, stereo reception is available

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 ofmem­ory channels, either by time or by carrier presence, pass­band tuning and squelch as well as treble andbass 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 beattached to the
frequencies and modes stored.The remaining 1200
memory channels allow frequencies tobe 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 donot require
battery backup and are thus unaffected bypower 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.

POWER SUPPLY

AC ADAPTER and EXTERNAL DC POWERING

The etón E1 receiver is supplied withan AC ADAPTER.
TheAC ADAPTER is designed to be plugged into a wall
outlet that supplies AC power, or another source ofexter­nal filtered DC power between 7 and 12VDC may be
used.

Connect the output connector of theAC adapter,or other
power source, to the 9 VDC, 1 amp connector on the side
of the receiver.

If batteries areinstalled and external power islost, 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
found on page 20, paragraph 27b.

UNPACKING

Carefully remove the etón E1 receiver and included AC
ADAPTER wall transformer from theshipping carton and
examine them forevidence of damage. If any damage is
noted, immediately contact the transportation company
responsible for delivery, or return the unit to the dealer
from whom it was purchased. Keep the shipping carton
and all packing material for the transportation company
to inspect. The original carton and packing material
should be retained for repackaging should it be necessary
to return the receiver. Inspect the packing material for
any accessories or printed material before storing the
box. Locate the registration card, fill it out, and immedi­ately return it to etón to insure registration and valida-
tion of warranty.

LOCATION

For fixed locations, the etón E1 receiver should be oper­ated from theACADAPTER. Keep curtains and other
flammable material away from direct contact with the A
ADAPTER to avoidoverheating the transformer which
could result in failure or fire.

operated from four (4) internally mounted "D"cell bat­teries.These batteries are not supplied and must be
installed prior to portable operation of the receiver. See
BATTERY INSTALLATION section on page 9 of this manu­al. For longest battery life, alkaline batteries are recom­mended for this product. NOTE: REMOVE THE BAT-

TERIES IF THE RECEIVER IS TO BE STORED OR OTH­ERWISE NOT OPERATED FOR AN EXTENDED PERI­OD OFTIME TO AVOID DAMAGE TO THE etón E1
DUE TO POSSIBLE BATTERY LEAKAGE OR CORRO­SION EFFECTS. The etón E1 receiver does not rely on

the batteries for retention of memory channels. If power
is lost, clock settings aremaintained for aperiod of
approximately 10 minutes to allow time to install new
batteries. As long as good batteries are installed in the
unit, the clocks are maintained regardless of whether
there is external powerapplied or not.

ANTENNA REQUIREMENTS

(Refer to Figure1, page 12)
The etón E1 receiver incorporates side panel switches to
select between the internal telescopic antenna and vari­ous types of external antennas.The built-in telescopic

RIGHT SIDE AND REAR VIEWS

Antennas such asdipoles,trap dipoles, verticals and
long wires will provide the best results on the LF,MW,
and SW bands. The type to use for bestresults depends
upon the desiredreceiving frequency,and will normally
provide adequate results on the FM band.OutsideTV
antennas, folded dipoles, or coaxial antennas will pro­vide the best results for reception of the FMbroadcast
band, but will not provide optimum results on LF, MW
and SW bands.

Connect the outside antenna feed to the “EXT.ANTEN­NA“ jack locatedon the left side panel. The best anten­na for any of the previously mentioned frequency bands
will depend on the frequency range and time of day for
the particular signal in question. Refer to publications
such as theARRL Handbook orARRL Antenna Manual
(available in most public libraries) for help on selection
and/or construction of the antennas mentioned above.

which of these screens was being displayed when the
‘TIME’ key was pressed the firsttime.The receiver dis­plays the time when in the off mode, and when in this
state,pressing the ‘TIME’ key will togglethe 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 orAUX modes. In MEMORY or COUN­TRY modes, the stored PBT value willalways be recalled
and “MEM” will be indicated above the‘PBT’ softkey
until changed.

16. DX

The ‘DX’ softkey turns onor off an RF preamplifier which
is useful in improving the readability ofvery 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 orwhen 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 thatbattery life will be reduced
somewhat if DX is enabled during portable operation.

17. FAST / TUNING LOCK

Repeatedly pressing the FAST /TUNING LOCK key cycles
through the available tuning rates for the current oper­ating mode, as explained in more detail under“Tuning”
which follows. Holding down the‘FAST / TUNING LOCK’

key for approximately 2 seconds will lock out the ‘TUN­ING’ knob and will cause “TUN LOCK”appear on the
display. Depressing the keyagain 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 determinedby the bandbeing
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
MEMORYmode,the ‘TUNING’ knob scrolls through the
500 MEMORY channels one at atime.If the ‘FAST/TUN­ING LOCK’ key is pressed,“FAST”appears on thedis­play and the‘TUNING’ control scrolls through the 500
MEMORYchannels 10 at a timeas 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
MEMORYchannels one at a time.

The ‘TUNING’ knob is also used when programming in
MEMORYmode 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 atime.If the
‘FAST/TUNING LOCK’ key ispressed,“FAST” appears on
the display and the ‘TUNING’ knob scrolls through the
available countries one country at a time with10 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 Softkeys

The purpose of each of these softkeys is shown along
the right edge of the display when the receiver is in the
ON state. From topto bottom their descriptions are as
follows:

FM / AUX - Pressing this softkey toggles between the
FM broadcast band and the AUX function.The selected
function will bein reverse video. The first pressof this
softkey selects the FM broadcast band (76.0- 90.0 MHz
or 87.0 -108.0 MHz) and causes the label for this key to
appear as “ FM /AUX ”.When in FM mode, only the
MENU function softkey along the bottom of the display

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.

2. SQUELCH LEVEL INDICATOR

This bar advances as the ‘SQUELCH’ knob is turned
clockwise. It indicates the level at which the incoming
signal is strong enough to overcome the SQUELCH set­ting. If the SQUELCH muting is enabled (which is done
by menu) a signal level that is higher than the
SQUELCH setting will be audible, while one that is
below the SQUELCH setting will not. A signal stronger
than the SQUELCH setting will cause scanning to stop
on that frequency if the “CARRIER” stop mode is
selected in the “RADIO SETTINGS” menu (item 2).

3. INTERNAL/EXTERNALANTENNA INDICATOR

EXT ANT or INTANT will be displayed depending upon
whether or not the mode in use (FM or HF) has its
respective antenna switch on the side panel in the
internal or external position.
