Curious behaviour of XV50 LEDs

harryweston

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.
