Re: [Elecraft] KPA500-KAT500-K3 problem
Sam, I run the KX3 line: KX3 to a KXPA100 to an Ameritron ALS-600 to the KAT500. Little lines all over the place, and hi-power LMR-type coax out of the linear. Cardinal rule, I am told, is to avoid those high power RF coax cables as much as possible in proximity. For instance, never drape a control cable or a display cable across the coax. You’ve probably tried all of this, but my two cents.

Re: [Elecraft] KPA500-KAT500-K3 problem
Sam; It sounds like the Auxbus is no longer connected from the KPA to the KAT/ K3. Make sure the 15 pin connector is solidly connected on both sides at both the KPA and the KAT. Also, make sure no pins in that cable are bent. - JackB, W6FB Sent from my iPad On Dec 22, 2014, at 6:26 AM, Sam Morgan k5oai@gmail.com wrote: I unseated and reseated the KAT500 to KAT500 Cable. make that: I unseated and reseated the KAT500 to KPA500 Cable.

Re: [Elecraft] KPA500-KAT500-K3 problem
That was my thought Jack. I just re re checked, no bent pins, and both ends firmly reseated. no joy :-( On 12/22/2014 8:43 AM, Jack Brindle wrote: Sam; It sounds like the Auxbus is no longer connected from the KPA to the KAT/ K3.

Re: [Elecraft] KPA500-KAT500-K3 problem
The KPA is still set for RADIO= K3, right? Shortly after power up, the KPA will send its on state to the K3 using the Auxbus, but only if it is told the radio is a K3. The symptom is that this is not being received by the K3. The logical conclusion is that something is blocking it. Nothing messed up on pin 2 of the AUX cable, right? I don't remember if the K3 must be told about the KPA (don't think so, but that would have been long ago...), but if so make sure of that setting. I'll research this a bit more when I get back to my info system, maybe an hour... 73, JackB, W6FB Sent from my iPhone On Dec 22, 2014, at 7:16 AM, Sam Morgan k5oai@gmail.com wrote: That was my thought Jack.

Re: [Elecraft] KPA500-KAT500-K3 problem
The only cables changed during my clean up were: I removed the VGA cable from the P3 (the one that went to the external monitor) I then took that end that had gone into the rear of the P3, and inserted it into a 4 way switchbox. I then added a new VGA cable from the switchbox to the rear of the P3 == at no time were any other cables unseated, removed, replaced, or otherwise messed with. (other than being lifted so the vga cable could be untangled from them if needed during the change over of the VGA P3 cable) On 12/22/2014 9:35 AM, Dick Dievendorff wrote: I'd try swapping the 15-pin cables between K3 and KAT500 and KAT500 to KPA500 if there's any possibility you swapped them in your cleanup effort. If you could possibly have swapped in an SVGA cable, I'd do some ohmmeter checking to see that all the cable pins are connected straight thru and not connected to one another. 73 de Dick, K6KR -- GB 73 K5OAI Sam Morgan __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KPA500-KAT500-K3 problem
Yes RADIO is still set for K3. Last night I had never even touched the cable that went between the KPA500 and the KAT500. Unless Murphy got in here while I was sleeping and broke a wire inside the cable that hadn't been touched... yea I know stranger things than that have happened b4, hi hi.

Re: [Elecraft] KPA500-KAT500-K3 problem solved
Connection to Pin 2 somewhere in the K3 to KAT500 cable is broken! thanks to *all* who pointed the way to troubleshooting the problem!!! On 12/22/2014 10:51 AM, Jack Brindle wrote: I just went back and read Sam's original post. Both KPA and KAT are affected. This comes form the info that the KAT is not following the K3 frequency, info that only goes through the AuxBus. The problem is either the cable from the K3 to the KAT, or somehow the AuxBus has been disabled in the K3. I don't think the latter is possible. We know that the band lines on the AUX cable are working just fine since both KAT and KPA follow the K3 band. both boxes get the band from the BAND lines and not the AuxBus (note for Sam - the KPA does not listen to the AuxBus, only talks. The KAT does both). So, check the cable from the K3 to the KAT. Pin 2 appears not to be conveying data. You might want to pull it and ohm it out. Also note that this must not be a VGA cable, but a straight-through connection with no lines shorted together. But you already knew that... We will get you going shortly. Intermittent are number 1 on the devil's list... 73, JackB, W6FB -- GB 73 K5OAI Sam Morgan __ 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 Message delivered to arch...@mail-archive.com
