I need some help troubleshooting an issue. K2+KSB2+K160RX+KIO2+KAT2+K60XV+XV144+XV222+XV432+IMA rework module
I have not spent much time using this rig on SSB but I plan to use it to drive the transverters. So as part of the setup & checkout of the system I am noticing that my SSB power level seems pretty low compared to my CW power level. Specifically when I test my transverters I am getting my expected power on all of them with CW. (The transverter power level on each unit is setup for driving the input power level for the brick for that band.) 144: 25w CW --expected 222: 10w CW --expected 432: 10w CW --expected When I change over to SSB the power level is almost nothing 144: 1-2w SSB 222: less than 1w SSB 432: less than 1w SSB I am using an Icom HM-36 mic (and have tested with two Heil headsets with similar results). SSBA=3 and SSBC=4-1 Initially I was thinking that I had an issue with Mic bias but I am not so sure now. I configure my computer to send modulated CW over SSB to compare the output level against a native CW signal. The spread matches the info above. It appears that my SSB audio level is attenuated for some reason. (The audio reports are good with no distortion.) Any suggestions for where to look on the KSB2 or an adjustment that I might have missed? 73 de NG0R -- John Hoaglun NG0R - EN25 http://www.hoaglun.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
