West Mountain Radio Operating Manual
VOX Delay : When the DXpro is configured for “VOX” operation it controls the
amount of time before the transceiver switches back to receive.
For many digital signals the control can be fully counter-clockwise (shortest
delay time) but should relay chatter be heard, e.g. on Hellschreiber, increasing
the control clockwise will prevent this.
The rule is to use as little VOX delay as possible to ensure you have a good
TX/RX turn-around time. This is important for ARQ modes such as ARDOP,
VARA, WinMOR, & Packet Radio.
SW1 AUD (mic/sub) two position switch. When the switch is in the mic (up)
position then audio from an attached microphone is diverted to the “DXpro Mic/
Sub” sound card recording channel (mono).
When the switch is in the sub position (down) then audio from a sub receiver
output (if connected) will be present on the “DXpro Mic/Sub” sound card
recording channel.
SW2 AUD (sub/main / main) two position switch. When the switch is in the sub/
main (up) position and a transceiver with Main/Sub Receive audio is connected,
Main Receive audio will be present on the left recording channel, and Sub
Receiver audio present on the right recording channel on the “DXpro Main/Sub/
TX” sound card.
When the switch is in the main (down) position then Main Receiver audio will be
present on both the left and right recording channels. This is the position to use
when connected to a transceiver which only has a single receiver.
TX three position switch : This switch decides which method of PTT (transmit)
to use; RTS, OFF, or VOX.
When the switch is in the com (up) position then the DXpro will trigger the
transceiver when the RTS serial signal is activated by your digital mode, or
voice keying software.
When the switch is in the off (middle) position then the DXpro will not permit
transmission (TX inhibit).
When the switch is in the down (vox) position then the DXpro will put the
transceiver into transmit when it detects audio of a sufficient volume to trigger
its internal VOX detector.
PTT LED : This LED will illuminate when the DXpro is in transmit mode.
KEY LED : This LED will blink when the DXpro is doing a keyed transmit mode
such as CW or FSK RTTY. It will illuminate when the TX switch is in the VOX
position and audio is detected.
