Good job! I just did S&P for DX only, for limited time. Caught a few South Americans on a very short 10-meter opening, which was nice. Wes N7WS

Why didn't you stop there? AFSK on a K3 is a dream and delivers a superb signal. Wes N7WS

Good job.

Larry, First, you should not need an external sound card. If you go into Control Panel and select Sound, you will have a Playback and Recording Tabs. These should be where you point WSJT-X in setup. A

Good grief, he's backing up a radio config file. The CD will probably outlast the radio. Wes N7WS

Distortion is the enemy. Back in the late seventies-early eighties I did a lot of experimenting with HB receivers and EME. Distortion, although it may or may not affect short term intelligibility cert

Several different SDR programs will control the SDR-IQ, but why? I find most of them ghastly, with bells and whistles thrown in just because they can. If your application is a bandscope, looking at a

I would call that a second receiver, not a panadapter/bandscope. I use an SDR-IQ with SpectraVue software for my bandscope. SpectraVue knows all about the K3/K3S i-f output frequencies v. mode and BW

Yes

I wouldn't expect it either. Nor would I accept it. (Actually, I would, I never use the clock anyway.) Wes N7WS

Your K3S tunes above 30 MHz? Mine doesn't.

If the frequency given isn't a typo, the K3 won't tune that frequency or any of its harmonics. Wes N7WS

I would be tempted to put it on 40 (mid-band) and tweak trimmers C132 and C153 just a little and remember where they are set so you can return if needed. I've had some of these go intermittent on my K

Somewhere in the literature for the K3S I saw mention of digital correction of the TCXO. I posed a question about it and never got a reply. But the TCXO has only three pins so it can't have any. Wes N

You don't say what reference oscillator you have in your K3 or which synthesizer is installed. I'm not a fan of fldigi so I am not comfortable commenting on its performance, but if I understand correc

I haven't done this but I think the following will work assuming a KXV3 is installed: 1) Put a dummy load on the receive only K3(S) antenna port. Crank the TX power to zero. 2) Put the receive only K3

Oops, my mistake. I was thinking of Clifton Labs.

That's going to be difficult, he's a SK.

Assume 15 dB gain (Max allowed by FCC) and the K3 running at 8W = ~250W. My K3S on 160 meters puts out 237W according to an LP100 power meter with 8W drive. Why only 8W you ask. Because that is a safe

Because a K3/10 can't fully excite a KPA500. Wes N7WS
