[Elecraft] Curious behaviour of XV50 LEDs

[harryweston at beeb.net]

Hi

I have completed construction of an XV50, in fact I finished 
it a while ago, and it all seems ok except for one thing. The 
Tx power LED display only lights one at a time, even though I 
have GRPH=BAR and OPT=PERF selected on the K2. It does the 
same if GRPH=DOT is selected, too.

Is this possibly due to an assembly fault? If so I'd be glad 
of an indication of where to look. I have done very careful 
inspections of my soldering and can see no dodgy joint that 
may be the culprit. Is there perhaps one connection that may 
cause this, or any diagnostic procedure that I can follow to 
trace the fault?

I am using it as the only XV connected to my K2. the K2 
software is displayed as '2.01H 1.02', and the XV50 U1 has a 
label with 1.6e on it. I have K2 #2378 (without the 100W amp 
etc) with the A to B updates and K160RX, KNB2, KIO2, KDSP2, 
KSB2 and KAT2 installed. An external meter shows that the 
power going out to the antenna is what it should be according 
to the one lit LED.

I must have done something silly to get this effect, but I am 
flummoxed. Has anyone else experienced this phenomenon? I've 
seen a lot of problems solved on this reflector, and hope 
that the kind and knowledgeable people out there may be able 
to help with this one.

I normally read any Email -- it's almost only this reflector, 
in digest form -- once a week on Sunday evening, so please 
forgive delays in replying to any response to my plea.
