Elecraft KIO3B and WSJT-X

After I installed the KIO3B board in my K3, I found that running WSJT-X creates 2 or 3 S-units of noise in the rig but WSJT 10 runs quietly.Tried different computers, different cables, different jacks, and scads of ferrites on the USB cable. Nothing seems to help.Has anyone else run into this problem?

Re: Elecraft KIO3B and WSJT-X

That's really odd! It's quiet until the program starts?

What happens if you run 10 and X concurrently? Start up 10 first, it's quiet, then start X?

Audio config on X is identical to 10?

HA!! Try turning off CAT control in WSJT-X. I bet the program is changing something on the rig to make the noise come up.

Re: Elecraft KIO3B and WSJT-X

I tried starting 10 first then X and it didn't seem to help.Yes, the audio config is the same in both programs.I turned off CAT but once again it didn't help.
I asked Elecraft tech support about it but they had not heard of another case and could offer no help.

Re: Elecraft KIO3B and WSJT-X

So, you're saying everything is fine with 10 running, and as soon as you open X the S-meter goes up? If you close X with 10 still running does the S-meter go back down?

When you disabled CAT control in X, did you close the program and get back to the low noise level, then launch it again seeing the S-meter go back up? If so, with X running did you check in the settings to make sure CAT was still off?

When the noise is showing on the S-meter, does unplugging the USB cable make it go away?

That's a good clue, Bert!

So turning off the monitor should kill the noise. Easy to test.

Funny you mention it. I'm going to test a prospective new monitor today. I'm trying a smaller one so I can fit 2 on the operating desk. I find lots of them are unusable, either the monitor or it's PS generates noise, or they are susceptible to RF.

When full-screen, the waterfall (which is darker) is substantially quieter than the operations screen. While I have figured out how to configure the waterfall palette (I use ZL1FZ palette), I have not found an adjustment for the operations screen.

Re: Elecraft KIO3B and WSJT-X

Josh,

See if you can find a monitor with an external power supply that
produces 12 volts.
If you can accomplish that, connect the monitor to the shack 12 volt
power system instead of using the switching 'wall-wart' that comes with
the monitor.

Re: Elecraft KIO3B and WSJT-X

Adafruit had some nice 12V displays. Most of them are HDMI which
may be a problem. They change what they have frequently and it's
been a while since I last looked.

It's a good idea, but too severely limiting since almost all monitors
now run on 19V. Thus far the HP 23es is fine. I ran RTTY with it next to
KPA500 on several bands with no issues. Final test will be pointing the
6m EME array at the shack and listening. The monitors look really good
and were on sale at Best Buy for $119!

Re: Elecraft KIO3B and WSJT-X

As recently as a year ago, I was still seeing Samsung 24-in monitors
running from nominal 14VDC supplies. I already own several, and bought
another to have as a spare. They're 1920 x 1080.

Re: Elecraft KIO3B and WSJT-X

Dave,

It is usually the POWER SUPPLY that causes RFI, NOT the monitor. To
verify, leave everything connected but unplug the POWEr SUPPLY from 120VAC

HI Josh:

Another possible source of 12 VDC powered monitors is the Recreational Vehicle industry. Many RVs have appliances (including TVs) that are powered from the "house battery", which is almost always a 12 VDC system. And, many TVs have a VGA port on them... plus video, and HDMI, as well as an antenna port.
