Transmitter Operation
tiMe-Out tiMer
Most often used on FM, the transmitter’s Time-Out Timer (TOT) feature disables the
transmitter after a user-dened period of transmission. This feature may be useful in preventing a “stuck microphone” (accidental closure of the
ference to other users, and it will also force you to keep your transmission short, thereby
conserving battery power.

Monitoring of HF WeatherFax broadcasts is easily accomplished using the
1. Before proceeding, be certain that the WeatherFax demodulator is properly connected
to Pins 5 (DATA OUT 1200bps) and 2 (GND) of the rear panel
2. Set the transceiver to the VFO mode, and set the operating mode to “DIG,” setting
Menu #26 to PSK31-U, as described previously.
3. Now, select the operating frequency of the station transmitting the WeatherFax broadcast. Note that, in the USB mode, the frequency you should program onto the display
is typically 1.90 kHz below the station’s “assigned” frequency. Thus for a WeatherFax
station assigned to 8.682.0 MHz, tune to 8.680.1 MHz.
4. When the WeatherFax broadcast begins, no further operator intervention should be
needed from the transceiver standpoint. The audio level from the
rear of the transceiver is xed, and cannot be adjusted.
Fine adjustments in the gray-scale and the frame alignment are accomplished using the
computer and software connected to your WeatherFax demodulator.
