[Elecraft] K1 Transmitter problem

[Dennis Rayfield]

I've build an RF Probe, and worked through the transmitter signal tracing section.  All of the voltages are within range until I get to the band-pass filter.  I'm just reading .07 volts rather than the 0.5-1.0 that it should read.  I have the 4 band module (40, 30, 20, 15) and the relays click when I change the bands.  

Thanks for any help.

73,

Denny - KI3F

Re-flow the soldering with a hot soldering iron - 750 degF if you used leaded solder, 800 degF if you used unleaded solder.

I use the out menu to set the output to 3 watts, but when I put it into tune mode it immediately shows P0.1 on the display and there is no power out.  When I take it out of tune and go back to the out menu, that still shows 3 watts.
