Need to isolate ... try without amp ... if possible, jumper antenna(s) so that the switches are not used. Could also be a relay. Any barrel connector is suspect if it isn't Amphenol. And so on

When you solve this, please post the solution... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist ARRL Asst. Director, NW Division, Technical

I had a similar problem, but on only 6 thru 20m. Traced it to a dirty? center pin PL259 connection at the antenna. I inspected than cleaned it with DeoxIT. Problem went away. 1 year later it

Someone mentioned earlier there are fake APP's around. The fake insert has a large A imprinted on the tongue. The fake one is 0.5mm thick where as the proper one is 0.6mm thick. The proper one has a

Same thing happened to me and was caused by faulty connection. RAS

That is exactly what it sounds like... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist ARRL Asst. Director, NW Division, Technical Resources

I am not sure where to post this question. I have K3s to KPA 1500 to remote antenna switches to various antennas. Radio can be dead quiet, like not connected to an antenna. I touch the key to

My K3 is serial number 21 and is the first kitted K3. During assembly, I was concerned about the tension of the pre-installed Anderson Power Pole attached to the rear panel. It

Also use Anderson Power Poles for all my 12 volt DC - buy them from a reputable source ( SOTA Beams in the UK) and use a decent crimptool from the same source. No problems at all in my shack. Use a

I've had zero problems with APP connectors, in any application. They're an em-comm standard, and have been far less problematic than Molex or other connectors. We assemble them according to the

Sounds like there is something wrong with that pair. Elecraft have been using APPs for some time, the K100 (K2 Amp) comes with APPs. I have K3 Serial No. 174 and never had a problem. And I’ve used

My K3 is S/N 00158, as stated in my QST review. The power cable came with the radio. Is it possible that very early on, Elecraft did not crimp its Anderson Powerpole connectors? The problem is that

I've also used these connectors (but not on my K3) and find them robust, reliable and good value for money. 73, Quin G3WRR

Charlie – I made the (not so hard) decision that the only ‘standard’ I need is MY standard. 73 Lyn, W0LEN

Very nice, re-usable and relatively cheap connector, Lyn. Sure wish they were the standard instead of those one shot, (deleted expletive) A-P’s ! 73, Charlie k3ICH

I have replaced several troublesome APP connectors with these, and have had zero failures: <https://www.amazon.com/MCIGICM-Upgrade-Female-Bullet-Connectors/dp/B07Q2SJSZ1?ref_=ast_sto_dp> 73 Lyn,

I second that, everything 12v in my shack etc is APP. only if it has an adapter that goes in a ‘cigar’ socket does in not. -73 de M0XDF

If you're having problems with Anderson Powerpoles, then they've been incorrectly fitted, or are fakes. They do NOT need soldering, unless it's to a PCB. Crimping is actually more reliable than

Remove ALL other Connectors and Wire Direct to the K3. Get another power supply for the other stuff, then you can the Anderson Poles. KISS. - WA6VAB Sent from Mail for Windows 10
