Operating the Transmitter
- Set the micrphone gain for about 50%. You may want to make a
finer adjustment based on actual transmission experience. In general, during
transmission the "Power" meter should register between "60 - 80" and
the "ALC" reading between 15 and 25 (30 is maximum). Make the necessary
adjustments using the mic gain and the NetMeeting microphone volume slider.
- For SSB operation, depress the "space bar" once for
PTT (DO NOT HOLD IT DOWN). Depress it again to end transmission,
or you can click on the red "Push to Talk" button for this function. At the end
of your transmission you may notice a muffled echo of your last few words after you stop
talking due to the time delay in transmission of the actual audio packets over the
- At the end of each QSO, you say something like, "This is
<Your CALL>? operating the W4MQ remote controlled HF station over the
Internet". to clearly reflect the status of the operation.
- You may activate the "Tx Equalizer" to improve
transmit audio quality. Click on the label and "H Boost" will be shown.
- Power may be limited by the host station. If you select a
power greater than the limit, the display will update with the limit emforced by the host
- There is an amplifier available on HF at times. It is set
manually to a specific band by W4MQ. If your priviledges permit, you can turn it off and
on by clicking on the green label "Amp. Avail." if it is shown in the
- .The "Monitor" can be used to listen to your
transmit audio delayed by the Internet packet delay time. You probably will want to use
this feature for testing purposes only and not during a QSO. Be sure to set power to 5
Split frequency operation is available. The keyboard commands
- "s" to enable/disable split
- "e" to set receive and transmit frequency equal
- "x" to swap receive and transmit frequencies
(note that only the receive frequency and mode can be
directly changed by keyboard entry)
The SPLIT indicator will be visible in Frequency display
panel whenever split operations is enabled.
