[Elecraft] K1 4-band board problem

[James C. Hall, MD]

Hello all:

I finished a four band filter board to replace my 2-band board. All went
well with the construction but when the alignment steps were undertaken, I
ran into problems. First since my K1 was a Rev. D, I had to resolder R36 on
the RF board. That being done, all went well except for 20M with a output of
0.1 watt. All other bands tuned easily. So I'm left with what is specific to
20M. I resoldered the crystal pins and ground, checked and resoldered relays
K2, K5, and K6 and all surrounding capacitors, and the trimmer capacitors
specific to 20M. Still no output on this band. I noticed on this band on the
receiver alignment, that the AF output was much quieter than the other
bands, but the trimmers did peak the noise.

Little help please !!
