Re-programming the IC M802 to utilize simplex calling channels is easy. Re-programming of the radio
will change both the transmit and receive frequencies to those listed as the transmit frequencies in the
table. The 2177.0 channel is already a simplex channel and will be retained. Both the Scan Frequencies
and Call frequencies must be changed.
A custom procedure specific for this change to the radio is provided below.
Delete the old Scan Frequencies
The Scan Frequency memory is full as the IC M 802 will only scan six frequencies and has been
programmed for six frequencies by ICOM. The first procedure is to delete all the scanned duplex
channels to allow re-programming the radio for simplex channels.
1.
In DSC Watch press [
SET
/MODE] to display the
DSC MENU
.
2.
Rotate the [CH] knob to select
Set up
and press [ENT].
3.
Rotate the [CH] knob to select
Scan frequency
and press [ENT]
4.
Rotate the [CH] knob to select (each of the duplex frequencies one at a time) and press
[ENT].
5.
Press and hold the [CE] until two beeps are heard and that memory location will be
clear.
6.
Repeat this procedure for all except the 2177.0 frequency.
Program the new simplex Scan frequencies
1.
Rotate the [CH] knob to select
<add>
and press [ENT].
2.
Using the Keypad, enter the desired label for the new frequency, e.g. 4MHz Ship, 6MHz
Ship, 8MHz Ship etc.
3.
Rotate the [CH] Knob to move to the TX:_ _ _ _ _ . _KHz and enter the new frequency.
{4MHz: 4,208.0; 6MHz: 6,312.5; 8MHz: 8,415.0; 12MHz: 12,577.5; 16MHz: 16,805.0}
4.
Rotate the [CH] Knob to move to the RX:_ _ _ _ _ . _KHz and enter the same frequency.
5.
Press [ENT] to save the scanned frequency.
6.
Repeat this procedure for all five frequencies.
7.
Note display should indicate <add> Memory full when all five scan frequencies have
been added. (The six frequencies including the 2177.0 we did not erase.)
8.
Press [SET/MODE] button to return to
DSC Watch.
Delete the Duplex Calling Frequencies
Now re-program the calling frequencies the same way. While the Call frequency memory is not full, we
would fill the memory before all the simplex channels are entered. So we will start by deleting the
