Chapter 12 PACTOR Operation
If the changeover time from transmit to receive in your radio set-up is too long, the ack signal from the distant
station will arrive before your radio has switched back to receive. However, if the transmitting station is further
away, the transmission time over the propagation path will delay the arrival of the signal until after your radio has
switched to receive. For this reason, you may be able to link with stations across the world easier than across town.
If switching-time problems persist, you may have to make changes in the radio to eliminate excessive time delays:
♦
Remove large decoupling capacitors from the Push-To-Talk line to allow faster PTT (transmitter)
activation;
♦
Improve power supply decoupling, especially in audio stages.
♦
Don ’t use the squelch control.
Another solution is for either you or the other station to change the timing value in
ADELAY
.
In case you can’t solve your radio’s switching-time problems, call AEA for assistance.
Control Key Summary:
CTRL+B
Sends your
AAB
message.
CTRL+C Takes you out of the Converse mode and into the Command mode.
CTRL+D
Stops your radio from transmitting when the transmit buffer is empty.
CTRL+E Sends a “Who Are You” (WRU?) request to the other station. This causes the other station to send
its callsign. (...and serial number of the PACTOR chips if it’s a DSP232MBX.)
CTRL+F
Unkeys the transmitter after the transmit buffer is empty, sends your callsign in Morse, then returns
the DSP to PACTOR Standby in the Command mode.
CTRL+T
Sends the time if
DAYTIME
and (or) date if
DAYSTAMP
is
ON
.
CTRL+Z Changes your DSP from send (ISS) to receive (IRS).
