Hi chuck

I am driving an old homebrew linear with K2.

Amp is PL509 / 519 grounded grid job.

I have 2 valves / ? tubes in it.

Got about 100 to 150 w keydown on CW with 12 -15 w drive from K2.

when QRP become tough ----wee bit of power helps

Regards

For a few days now, I've been driving my Ameritron AL80B amplifier with 10-15 
watts from my K2, yielding roughly 100-150 watts output on CW (no QSK).  It's 
been working very well.  I thought I'd share how this is implemented, in case 
anyone else is interested. 
 


One of these days, I'll try the KPA-100, but for now I'm able to enjoy the K2 
at the "standard" 100 watt power level with what I have in the shack. (No, I 
haven't tried driving the amplifier with the Sierra !)
