[Elecraft] K3 PSK no output

[Jay]

Don

Thanks for the info...I have set the ALC per the KE7X manual. OK on the 
clarification...this radio is something I am not used to (starting out with 
a DX40 and a BC342) but worked my way up to the TS950 when it first came 
out.

And the TS950 still chugging along after all these years and a trip to 
Clipperton in 1992. I think the salt air on the island did take its toll on 
the motors in the antenna tuning unit. I never use it but they scream like 
crazy if I do push the button by accident :)

There are a lot of things to be set and Appendix C in the KE7X manual is 
something I have to go thru to get all 6 radios ready.

Thanks for the info
Jay
