[Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3

[Dick Dievendorff]

I believe the OM; query returns the result of the configuration menu
settings. The KPA3 menu setting should be "PA NOR".

Joe,

have you checked the 'internal information '  ?

-------------------------------------------------
use:

OM * (Option Module Query; GET Only)
RSP format: OM APXSDFf-----; where any of the letters APXSDFf, if present,
indicate installed and detected
option modules (see list below). The positions of the letters are fixed. If
a module is not present, its letter is
replaced by a dash (-). For example, if only a PA and sub receiver were
installed, "OM;" would return "OM -P-S--
------;". The five dashes at the end are reserved for future module letters.
Option List: The letters (and associated positions) in the OM string refer
to the following option modules:
A = ATU (KAT3), P = PA (KPA3), X = XVTR and RX I/O (KXV3), S = Sub Receiver
(KRX3), D = DVR
(KDVR3), F = Band-Pass Filter module, main (KBPF3), and f = Band-Pass Filter
module, sub (KBPF3).
--------------------------------------------------

During initialisation all installed modules are detected ... independent
what you have configured 
If your module is dead i would expect this to be reflected in the OM output.

In the past few days, I've noticed the KPA3 in my K3 serial number #584
acting "flaky".  Well, today it apparently failed -- or maybe I'm missing
something (?).  No matter what I do, the rig is limited to 12 W (or so it
says); I've switched the KPA3 on and off numerous times in software, I've
removed and reinserted the KPA3, I've checked the circuit breaker with a VOM
out of circuit, I've tried another power supply, and so on.  No joy.  Before
I contact Elecraft I'd like to hear the collective wisdom of the group --
what else can I try to get things working.

Tnx and MC!

73,

Joe, W2RBA
