1. [Amps] Kenwood TL-922A on 17 meters (score: 1): Author: "Steve Sala" <k7awb@msn.com>; Date: Thu, 24 Sep 2009 16:20:34 -0800; What do I have to to use the amplifier on 17 meters? I suspect that one uses the 21 MHz position since that is closer to 18 MHz than 14 MHz? Can the parasitic chokes take the frequencies?

It works better on that tap than on the 15m tap. That is not to say that your's will be the same. Try it out on both positions with low drive an; /archives//html/Amps/2009-09/msg00282.html (8,540 bytes)

The plate choke is series resonant around 18 MHz in many amps. I'm not sure the TL-922 configuration but you ma; /archives//html/Amps/2009-09/msg00283.html (7,771 bytes)

RF Parts sells them for about 25 bucks as well. http://www.rfparts.com/choke.htm; /archives//html/Amps/2009-09/msg00284.html (9,285 bytes)

Removing 3-4 turns moves the resonance up near the CB band; /archives//html/Amps/2009-09/msg00285.html (9,190 bytes)
