[Elecraft] K1 15/20 Meters dead

[SP5DDJ]

Hi Denis,

I had a similar problem on 40 meters. RX was OK on all four bands, but no TX
on 40 meters.
What I did :

-    checked all soldering points,
-    checked all relevant relays
-    checked all trimmer capacitors

No improvement

Then I inspected very carefuly  T4 transformer, and bingo. Secondary coil
wire had poor connection because of not properly removed enamel. In your
case, try to unsolder T3 transformer and clean legs once again and resolder.

Good luck & 72'ss
