[Elecraft] K3 / SLUSB / CocoaModem

[Jim Bennett]

Looks like I misspoke when I said I could leave the K3's PWR set at 90 and adjust the RF output via the SLUSB. Doesn't quite work that way! RF power out stays up in the stratosphere (PSK31 speaking, anyway) so I really do have to set the K3 to about 25-30 watts out on the K3 and adjust the ALC via the SLUSB. Still, it does seem to work pretty well.

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.
