Re: Topband: Oscillation in Narrow band tuned antenna.

[Jim Borowski <jim.gmforum@gmail.com>]

I think the word Oscillation was the wrong word to use. Usually it is noticable 
and happens on 160m.  It is more like RF feeding back on a loop causing a high 
SWR and you tune that out and the amp circuit putting out more power than 
needed and amp starts to over heat. Bigger heat sinks may help, but it is a 
patch not a fix.The fix is eliminate the RF loop, with. Common Mode Chokes on 
interconnecting cables between the amp and driver or XCVR and auxiliary 
equipment. Also eliminate Ground loops as well.Jim K9TFSent from my T-Mobile 4G
