My K2 has been working OK, until now...
80, 40 and 30 it has full output, but the higher bands, the output is down. Did the alignment for those bands as per the manual. Didn't make any difference. I get 4-5 watts on 20 and 18 and 21 about 3 w, ten is down to 2 watts. Receiver sensitivity is OK. Any "words of wisdom" will be greatly appreciated. 73 Ozzie, w6icm |

Did you solve your problem, Ozzie?
I ask because I have the same problem on one of my K2s and cannot fix it. Thanks and 73 de Chris, G4BUE

A couple of ideas: Make sure the trimmers that tune the bandpass filters
are not set at the extreme end of their range. Also check that T2 and T4 are wound properly, as shown in the manual.

Hi,
Replacing the output transistors did the trick. 73 Ozzie, w6icm Vic K2VCO wrote: > A couple of ideas: Make sure the trimmers that tune the bandpass filters > are not set at the extreme end of their range.
