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

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3
Thanks for the suggestion, Ed, but I don't see any hint of carbon on either the plug or the receptacle pins that connect the KPA to the rest of the radio. Do you know -- or does anybody know? -- what sort of quick check of voltages I could measure to check whether the KPA is functional? Thanks again, Ed! 73, Joe M. On 12/23/2009 7:43 PM, Ed K1EP wrote: This happened to me. The connector between the KPA and the vertical board failed. The contact carbonized. Once one of the six starts to fail, the others take up the extra current and then they fail. If you disassemble the KPA you will notice the blackening of the six pins that carry the PA current. Replacement of both the male and female connector is required. If you loosen the connection and wiggle things around, you might get enough friction to get it to run for a little, but it will eventually fail again.

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3
Dick, I experienced this same problem exactly on my SN 888, complete with intermittency of the symptom. After some consultation with Elecraft tech support, they sent me a KPAIO3 board -- the board that the KPA3 connects through and that contains the 12VDC sensor circuitry. Unfortunately, I haven't been able to get to installing it as yet. It's on the list for when I return from holiday vacation out of town. My bet is that this will cure the problem. I'll let the list (and Elecraft tech support) know when I swap it out and try it. Should be first week of January, possibly end of December.

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