[MRCA] RAT Net / RF-350

[Ray Fantini]

Played around with RTTY this morning on the Saturday 7087 RAT net, good conditions early working K9WT and K3TZJ and thought I saw KD2GFM in there for a second but never returned?
The object today was to just use the UGC-129, Dovetron and the RF-350 and wired the ON/Standby switch on the Divetron to the PTT line on the RF-350K but what a surprise! Discovered that the Dovetron will not print in the standby mode so had to quickly disable the PTT control line from the Dove and ended up using the UGC-129 for receive copy and cheated and used the computer to send.
The Harris RF-350 has VOX with both Data and voice modes that works on microphone and patch mode, but anyone have an idea why the VOX does not work when using the AUDIO 2 source? It would be easy to just use the AFSK control on the Dove to control the Harris but no love from the VOX in that mode. The computer uses the PATCH mode with that port but I long ago built a control line from the computer that works the PTT circuit in the PATCH mode.
Or do I have to build up a switch to put next to the TTY system for send and receive?

Imagine that if you have the ASFK card for the RF-350 this makes that all unnecessary but don’t ever think I saw just that card around.
expect to be trying again next Saturday 7087 850 shift
