transmit and receive channel.
11. MODEL CONTROL:
This control allows you to select one of three
following operating modes: FM/AM/PA.
12. FRONT PANEL METER:
The front panel meter allows the user to
monitor signal strength, RF power out and SWR level.
13. BAND CONTROL:
The Band control allows the user to select the
desired band.
14. ROGER BEEP/SWR:
When this roger beep in ON, an audio tone is
transmitted at the end of your transmission. This lets the person you are
talking to know that you are done speaking. The SWR position is
explained above (number eight).
15. ECHO/ROBOT/VC SWITCH:
Selects between one of the three sound
effects-Echo, Robot or Voice Changer.
16.
NOISE BLANKER SWITCH:
The middle position means the noise
blanker/noise limiter circuit in ON. The right position means that the
noise blanker/noise limiter is ON and the frequency display digits are
turned OFF. The left position of this switch turns the noise blanker/noise
limiter OFF and the frequency display digits remain ON.
17. CHANNEL 6/19/21:
The switch selects between channels, 6,19 or 21
for use with the “fixed” switch (switch 19) or with the Dual-Watch
function. This means you can go to any one of these three channels
immediately or you can “watch” any one of these three channels with the
Dual-Watch feature. This is our exclusive “TRIPLE-CHANNEL DUAL-
WATCH”.
18. FREQUENCY DISPLAY:
Displays the frequency that the radio is
tuned to.
19. FIXED/OFF/+10KHz SWITCH:
The left position puts the radio on
one of the three fixed channels that is selected by the channel switch
(6,19, or 21). This over-rides the channel selected by the 40 channel
knob. The right position adds 10KHz to whatever frequency you are ON.
In the middle, both features are OFF.
20. CHANNEL DISPLAY:
The channel display indicates the current
selected channel.
21. ANT/DW LED:
This LED lights green when the dual-watch circuit is
ON. It lights red when your SWR is higher than about 3:1. This is not an
exact indicator of 3:1 SWR, but it is an indication that you should check
your SWR reading.
