My first PSK-31 contact seemed to go very well. I simply adjusted the MIC level (Line) until there was 5-7 ALC bars. The adjustment was quite smooth.
Then I went off and did other things and I'm concerned I changed something. Now I have to turn the level way way down on the USB Audio CODEC (-16.4 dB). Then I add another -3 dB using fldigi. Finally, I adjust the Mic to Line = 17. The Mic adjustment isn't smooth. The major change was the addition of the KAT500 and KPA500 (stby) and I'm wondering if either I messed up a setting or maybe created an opportunity for some RF feedback that's affecting the audio. At this point, I don't know how to confirm the signal is clean (especially PSK-31). I've only had one report of a possible problem and a number of reports of "things look good" so I'm calling that a wash. I found nothing in the instructions that told me to drop the level of the USB Audio CODEC and -16.4 dB seems like a big drop. The CODEC is set for 16 bit, 48000 Hz. Am I worrying about nothing? Is your setup with fldigi and DATA A using the K3s's internal sound card similar? Thanks for your patience. 73, Kev N4TT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
