Colleagues, I have been running JT65A using the JT65-HF software for the past month or so with good results (several hundred contacts with at least half DX). I have a Flex-5000 and I am running PowerSDR 2.2.3 under Windows 7/32. I have set my Drive control to 100 and have adjusted the VAC TX gain for an ALC reading of -3 dB (-6 on the slider control). With these settings I get from 25 to 30 watts out, depending upon the band. This power output is adequate for JT-65A, but what if I wanted to run more power? The only way that I can get my power output into the 100 watt range is to do so by increasing the VAC TX gain to a value of at least 0 and then the ALC is up to +3 dB, which probably would create splatter all over the slice of spectrum set aside for JT65A.
Also, any other suggestions for DSP or other settings that would optimize J65A operation with PowerSDR would be appreciated. Thanks, Ed, K0KC _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
