[Elecraft] K1 Fix and Align

[Don Wilhelm]

Thom,

I am ignoring your request for a private email - but I believe I can 
help, and there may be other K1 users out there who may want similar 
information.

First I need to ask what specifically are you having trouble with in the 
transmit alignment.

If it is that you cannot adjust the pre-mixer and RF bandpass filters on 
the band board, all I can say is that you should re-do the receive 
alignment with a strong signal source of a known frequency within the 
tuning range of the K1.  Although on-the-air signals may be sufficient, 
they may not tell the entire story.

First make certain the BFO is adjusted properly to peak the FL3 passband 
at your preferred sidetone pitch.
Then turn the switch on the bottom of the K1 board to the TEST position 
and adjust the TX Offset trimmer so the audio frequency is the same as 
your sidetone pitch (use SPOT to zero beat).  Spectrogram is useful in 
setting te audio pitch properly.  You can download Spectrogram from my 
website www.w3fpr.com.  Scroll down on the opening page for the links.

After doing that, re-do the Premixer and RF Bandpass adjustments in 
transmit mode with the OUT parameter set to 1.5 watts.  Adjust for peak 
output power on each band.

I can do the alignment/repair/calibration of your K1 if you do not want 
to pursue it on your own.

You can send me a private email and I will send you my service form.

73,
Don W3FPR
