If you enter an incorrect digit at any time, simply
press the PTT and start over again (this does not key
the transmitter).
Mixed Receive (V
&
V,U
&
U) Operation
You can simultaneously receive on two
VHF
or two
UHF
channels, and select either channel as the main
channel for operation. During mixed receive, the sub-
channel receiver is disabled during transmit.
Pressing
@ ~
5
toggles transceiver operation be-
tween normal and mixed receive, with
5
selecting
either V&V
(RV
lit) or U&U
k)L
lit).
For example, to activate V&V receive, first press
5
as necessary so that
UL
is lit. Next, press
§)rJ ~O
(cmn
or
l2:B
appear in the display indicating which
combination is selected).
Afterwards, the DIAL knob,
8/®,
and
~~/:fJj
keys are used as before for tuning or scanning op-
eration on either receiver.
Note -
During mixed receive, sensitivity and
IMD
of
the alternate receiver is degraded slightly, however
this should not greatly affect performance, except in
highly RF-congested areas.
User-Programmed Keys
All transceiver functions and settings are accessible
via keypad sequences from the MH-39. As explained
before, most buttons have multiple functions, depend-
ing on the duration they are held depressed (less or
more than Y2 sec.), or if they are preceded by the key
entry
IpJ
~
(to enable their alternate function).
Two special keys,
~
and
Q,
can each be assigned
a function (of the users selection) to simplify routine
transceiver operation. This is especially convenient for
functions that require two-keystroke activation, as they
can now be accessed with a single push of a button.
Examples are: scanning, power output, spectra ana-
lyzer - any of the ivory-labeled functions on the keypad.
To program
U
or
Q,
hold either key while turning on
the power
(OJRJ
LEOs blink). Next, press the button
with the ivory label corresponding to the function you
wish to assign ...that's it. Let's try two examples:
