[Elecraft] K3 / SLUSB / CocoaModem

[Jim Bennett]

Problem(s) solved! Here is what I just posted on the CocoaModem Yahoo group page. Hopefully some other SLUSB/CocoaModem newbie will find this helpful...

I have found the problem, and the problem is me, myself & I. First off, there was some bogus information in the Applescript field. Once I cleared that, I was able to get RF out of the K3! On the receive end of things - well, this one was really, really stupid. The squelch sliders next to each receiver were in the far left position. I "ASSumed" this was the "squelch off" position. Nope - this was full squelch, preventing ANY decoded data from displaying. Ughhhh... I moved the slider to the right and bada-bing, bada-boom - I was getting text displayed. Now, to hook up a dummy load and make the necessary adjustments so I'm not overdriving things.
