Hello again folks, Sorry about the barrage of posts from me. Just playing with my K2/100 #6998.
I've noticed that when operating in SSB on 40m, requesting any power 15-20 W and up will always give me 100W+ output, measured into a dummy load. Voice peaks are higher and result in Hi Curr warnings occasionally. I can reduce the power above this threshold only by changing SSBC to 1:1 (normally run at 2:1 with my MH-2 mic) and winding the power out back to just on 11 W. CW and TUNE modes - all OK: power requested and power output track very well on all bands, including 40m. Bands above 40m on SSB are not affected - I mostly work 20m SSB and haven't noticed the power tracking issue there. ALC seems to control the power out well there. I suspect the Tx chain gain on 40m is too high for the ALC to manage when in SSB. Is there any way of making the ALC more aggressive on 40m SSB, without affecting the other bands too much? I remember seeing a previous post about this somewhere but haven't been able to find the details again. Any suggestions? 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-ALC-and-power-control-on-40m-SSB-in-K2-100-tp5719064p5719064.html Sent from the Elecraft mailing list archive at Nabble.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
