Greetings!

I'm trying to get up and running with a couple of the soundcard-based
digital transceive programs. I am running the audio output from my computer
to the six-pin data port on the rear of my IC-706 (pin 1, data in). No
matter how I configure the audio settings on my computer, I cannot get any
signal to transmit. I tried both VOX and manual keying to turn on the
transmitter, but no power goes out. When I disconnect the plug from the
audio output jack on my computer, I can hear the SSTV warbling very clearly,
but it isn't making it out of the transmitter. I've seen it recommended
that an audio transformer be inserted between computer and radio as an
isolator, but it's also stated that it's only to give clear tones.

Any suggestions? Many thanks in advance!

Six-pin data port?

That's a data port -- not audio, hence no power out.

Use either the 13 pin accessory connector or the RJ45 -- either will work.

Thanks Xpyttl!

The diagram isn't very clear on the 13 pin port. Would that be pin 11 for
analog input and pin 2 for ground?

Thanks again! 73

That would be correct. You get AF out of your soundcard. For receive, you
can take the AF from that connector to the soundcard. If I recall, this is
independent of the volume control which is pretty nice. You get tired of
hearing the squawk from the digital modes pretty quick.

Be careful of bridging some of those other pins. One of them is a supply, 8
volts I think. If you take it to ground there is an internal fuse that will
go. It's an easy replace, but it's kind of a sinking feeling when the radio
won't power up! The pins on that 13 pin DIN are mighty close.
