Especially the ground wire.

Indeed. I got tired of waiting for a K4 and wanting to treat myself to one last new rig, opted for a TS-890. The K3S is on standby and the K3 is a backup to the backup, One thing I do miss is the ease

It's the government they voted for. Wes N7WS

That was my question. VOX is developed after the mic/level control, so the VOX gain may (probably) needs to be adjusted per mode. I begged for VOX gain per mode to be included in firmware but it never

Don't freak out. The radio arrived with a factory setting. Just follow the manual to "install" the options. Filters, 100W Amp, etc. Run the TX and RX gain cals. Use the utility program to save the con

I don't see you listed in any recent FMT results, so I wonder about your technique(s). Mine, which don't include a K3, made it into the top tier in the last FMT. I was 0.03 Hz high on 80 and 0.01 Hz l

Not necessarily. Check you S/N with respect to the mod install instructions. Wes N7WS

Except if you actually look at those instructions you'll see otherwise. "This modification applies only to K3S transceivers equipped with the KPA3A 100 watt power amplifier, serial numbers 10732 (fact

I sent a screen grab to your arrl address but I seem to remember they strip off attachments so you may not get it.

Except when it isn't. And in my experience, bipolar amps vary with frequency just like FETs. Wayne points out something that is totally ignored in these IMD discussions, but something I've mentioned s

If TX IMD is the issue, K3 and K3S transmitters are a real mixed bag. My old K3 at 30 watts is fantastic, with IMD at all frequencies better than -40 dBc (ARRL method). The same radio at 10W is the wo

I never said a word. But still on the subject of age, as I said I hit 78 on Saturday. We just porked up this weekend with steak, desserts and wine at fancy restaurants. But the Sunday before we did a

Nonsense. It's intellectual property that can/might be used in other Elecraft products. I turned 78 yesterday and I wish they would start shipping K4s soon so I can start my, "wait a year after delive

I don't see a K3 problem, I think it's a problem with one, or both, bypass relays (K20-K21) in the KAT500, although I suppose it could be any one of the relays. Wes N7WS

Quoting myself from a 2016 post: "I share your dismay. I was at Visalia once many years ago and looked at the then current K2. Cute little radio but I couldn't stand the feel of the tuning knob. This

Wow, where to begin. Of course you don't understand the personal ethics of some of us. That's okay, they are personal, some of us have them some of us don't. In what follows, I'm speaking as a DXer, c

Oops.

I haven't used the transverter output for anything, so have no experience. It does appear however, that there isn't any closed loop power control on that output. (If there is, I'm sure I'll hear about

Don't be ridiculous. We are talking about desktop equipment here. I have experience with liquid cooled transmitters dating from the 1960-1980s. AIM-54A Phoenix Missile used a silicon-based coolant tha

Unless you have a supply of distilled water that you can dump down the drain after it gets hot, then you have to cool it off by rejecting the heat someplace else; usually into the air. Then you've som
