[Elecraft] XV-144--Not switching to TX

[Phillip Buckholdt]

Hi all

With all the traffic abt the K-3, I think my help request got lost.
So far, have spent 3 days trying to get this silly thing to work.
     Had a problem at the start of alignment.  K5 was energized all the time 
in the tx mode. Redid some solder connections on the front panel board and 
cured that problem.  Did the LNA setup and peaked inductors, and receive is 
fine.
I have the K60XV and, setup the XV as per page 5 in the manual. I setup my 
K-2 for the XV-144 as TRN 2 but, it is not turned on by the K-2. My XV-50 is 
TRN 1
      I setup the XV-144 per page 7 so I could do tests. the XV turns on 
with S-1 but will not go to the tx mode with Key in grounded.. Tried 
grounding the 8R/key line up to U-1, Pin 27 and no tx. Grounding the 
collector of Q-2 keys relay K-5.  Sounds like U-1 is bad but swapped working 
front panel board from my working XV-50 and have the same problem.

     RX on my 144 is fine. Can't find a problem on the RF board.  Help, 
don't have much hair left.  Have to mow the yard while we have sunshine. 
Does anyone have any ideas?.

              Thanks Phil
