I had a monitor problem last week when a video output went and I have had to change over PC. I have had to reload and install all software. Everything is back working almost. I have an SDR2 DX and run SDC64 with TCI. JTDX is running fine along with Logger32 and auto logs both to Logger and direct to LOTW. Yesterday I wanted to try out RTTY when somebody asked ME for advice and I found that RTTY was not working. I had forgotten that N1MM will not work with TCI and need a COM Port and a VAC.
My new PC is a little micro PC Dell Optiplex 3020 but only has ONE com port. No worries when running TCI. So I downloaded comOcom and created 3 pairs of ports COM3,4, 5,6, 7,8. I downloaded a VAC software of the type shown in the SunSDR2 Addedendum by Erik. It is running OK and I have created 6 VAC.
I am a little confused (Its over 15 months since I bought the Sun and got it running) as to what is an output and what is an input. When I go to OPTIONS, VAC should ny "receive" be an output or an input? I thought I'd try setting up MMTTY on its own so as not to complicate matters, but on trying to setup the sound card again I am confused at to which is the output and which is the input. Should the VAC in the Sun be an output to the PC Soundcard / MMTTY input and vice versa.
Bottom line is that the VAC in the SunSDR is showing a signal with a moving bar, but using the same nomenclature in the Soundcard / MMTTY I am not getting a received signal in MMTTY. I have checked my device manager and all COM ports are showing and under audio all VAC cables are showing. DM tells me everything is working OK. I have tried almost every combinations of in and out but cannot get RTTY working. Using TCI, FT4/8 works fb via TCI....
