I'm late to this conversation so excuse me if this is redundant: There is a P3 option to turn on when power is applied or to turn on only when the power button is pressed. It's an internal jumper desc

Yes, N1MM Spectrum Display is a very useful tool. It's not as pretty or tunable as the P3 but it's smarter, displaying spots and allowing click to QSY. You can click a call sign, a "handle," or anywhe

You could use a remote power switch to turn off AC power to the K3 power supply. The one I use is from Digital Loggers (no relation to ham radio "loggers") https://www.digital-loggers.com/. It looks l

Does your antenna analyzer show a fault anywhere along the feed line? My old MFJ has found rodent damage out in the middle of the field that was intermittent and power-dependent. Even if the analyzer

FWIW, Chuck, I suffered an indirect lightening strike about a year ago (probably traveled 400' along a TV cable to the house) that took out my KIO3. After replacement of the KIO3 with a used/available

Great to hear how you're doing SO2R with a single KPA1500, Ken. Thanks. Why do you need four A/B relays? Certainly, one switches the transceiver outputs to the amp input. And one probably switches the

Your contacts' problems do indeed sound RFI related and the ferrite suggestions made by others may help. There is also the possibility that he is suffering from a weak Internet service link on one or

KPA1500 Remote will indeed turn the amp on and off. Yes, it takes some screen space but that is well worth it to avoid “flying blind” running 1500 watts with no indication of what’s going on except tr

That is surprising, Wolf. My very early edition KPA1500 makes no detectable RF noise. It is less than a meter from the K3. The PS is on the floor, almost directly under the amp. I have not added any f

I have a Top Ten Devices Band Aide decoder picking up band data from the AUX/ACC connector (15 pin D-Sub) on my K3. I use the internal jumper pad in the Band Aide so that multiple bands select the sam

One thing to check is the phone plug body. Some cables, Radio Shack comes to mind, have such fat bodies that they don't easily plug in all the way. I've succeeded using an extension cable that has a t

Have fun, Wayne. We're now in Boise where an Uber driver said her peace officer husband and his colleagues will be maximally deployed on Monday in and near the zone. Boise itself will only be about 99

In an older K3, the "+" means you have CW QRQ set ON for better shaped elements and cleaner QSK at high speeds. It also disables IF SHIFT. I'm a little surprised that this mechanism survived into the

I'm not an expert but it's been working stably for me for a few years now. So here's some advice on where to look. For exact settings, you'll need to experiment or get more expert advice. Since your c

When this happened to me (seemingly uncommanded changes in DATA MD on the K3), it turned out to be my use of frequency memories that I had set up before getting into digital modes. The memories includ

Does your amp accept 4-line "BCD" band data or does it insist on using a serial data stream? I've always used the band data from the K3 ACC socket, cascading true-15 pin Y-connectors as necessary to p

I went to Dayton once. Peeyu! If I were to go again, I'd just go to hotel events, ignoring Hara and the convention ticket entirely. It's a disgrace to the fraternity. It's hard to believe any civilize

Bob N6TV was a beta tester of the new KSYN3A synthesizer board for K3. He did some detailed Before and After analysis. He doesn't subscribe to these lists and asked me to post the following article po

I use KPA500 Remote, available on the Elecraft site, written by KG6YPI, an employee there. It will run stand-alone from the operating position with a long serial cable to the KPA500 OR client-server w

Oops! I missed your comment about using the RRC COM1 facility to run Kxx500 Utility remotely. That's clever as it would obviate the need for a remote desktop. I'll have to try that when I want to run
