... as always Dick is right ... one nice command lost ... at least for me Joe,
do you get any ERR ... displayed after switching-on the K3 ? If not the installed KPA is responding to the internal commands. Did you check the relay as described in the installation manual of the KPA ---------- Connect a power supply to your K3 and test the fans and KPAIO3 interface control as follows: Press the POWER button to turn the K3 on. Hold CONFIG to select the Configuration menu, then turn VFO B to KPA3. Normally, the display will indicate NOT INST (not installed). Turn the VFO A knob to PAIO ON, then turn it further to PAIO TST. When moving between ON and TST, you should hear a relay click on the KPAIO3 board. If you don't, press the K3 POWER button to switch it off, then on again and retry the test. Turn the VFO A knob on past TST to FN1, then FN2, FN3 and FN4. The fans should start turning at FN1 and increase speed as you continue to FN4. Turn the K3 off and disconnect the power supply. ---------- vy 73 Thomas, DM7TN K3/100 #78 -----Original Message----- From: Dick Dievendorff [mailto:die...@comcast.net] Sent: Thursday, December 24, 2009 2:27 AM To: 'Thomas Norff'; 'jmalloy' Cc: elecraft@mailman.qth.net Subject: RE: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3 I believe the OM; query returns the result of the configuration menu settings.

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. vy 73 Thomas, DM7TN K3/100 #78 -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of jmalloy Sent: Thursday, December 24, 2009 1:38 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3 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 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
