I have K2 #4913 with SSB option installed. I know - I should
have waited on installing the SSB board until I finished the kit
but page 28 said to install them if I had them, so I did.
I went ahead at that point and finished the SSB board seperatley
because I had opened it's bag. I then finished the control and
front panel boards and moved on to the RF board. I followed
the manual and got to the test point.
Upon powering up, I got "INFO 201", followed a few secs later
by "Elecraft" then "INFO 080". I figured I got that because I
had only installed the SSB components on the front panel board,
not on the RF board.
I decided to continue assembly in the hope that installing the reciever
circuits (and the SSB board) would fix the problem. Nope! Same
error. I guessed I needed the rest of the rf board so I finished the
K2. I powered up - "INFO 080" stared at me. Did a master reset
with no improvement.
I'm not hearing anything on 4 mhz. Even after a reset, I hear NO
relays clicking. RF board's U1 shows normal voltage except for
pins 9 (-0.01v) and 10 (-0.02v) - they should be +0.2 & +0.15v,
respectivley. Pin 18 is dead. Pin 28 Shows 5.53V (normal).
I've done all that I should - checked my work as I worked 4-5
times along the way. Resistance checks were all in range.
Is this just U1 being dead? I haven't completed final assembly - is
there something there that I could install to fix this?
Help!
