Not sure what you mean by “rf filters”, but I had a similar problem here with my 7300 and PC, connected by a single USB cable.

I bought some clamp on toroids and put one at the end of the cable before it connects to the port on the computer. I also looped the power cable to the pc through a larger toroid up close to where the power cord plugs into the PC.

This fix solved my problems, and I can run 50-60 watts output to my vertical which is about 25 feet away. OH, make sure your rig and tuner are grounded too.

I ran into this problem on mac, got around it by adding an empty bash script into the .app package.

in wsjtx.app , show contents, create new file in Contents/MacOS named user_hardware, chmod +x so it can execute. contents of new file on next line

#!/usr/bin/env bash

wsjtx will then execute it and get back a good return value, allowing the app to continue. for windows it would be a bat file doing nothing, on linux same as mac os, file locations differ on those platforms, haven’t had a chance to try it on those yet.

Hi David,

there is a known defect in WSJT-X v2.2.2 with WSPR band hopping mode. If you need band hopping mode then I recommend you use WSJT-X v2.1.2.

locked World-wide Digi DX Contest Problem

John, K9MM
 

I'm running WSJT-X v2.2.2 on a Windows 10 Pro v1909 system with a FlexRadio 6600M using the slice-master interface to Smart SDR v2.62..

Soon after I enabled the "Special Operating Activity" mode for this contest on Saturday, I encountered a problem where the Decode indicator would remain illuminated at the end of the decode cycle and there would be no more decodes. I believe this is the same problem reported during Field Day. Clearing the decode window and hitting ALT-Z would correct the problem, but only momentarily.

I switched back to normal operating mode, but the problem persisted. I shut down and re-started WSJT-X, but the problem persisted. I shut down WSJT-X, slice-master, and the SDR software, but the problem persisted. Finally, I re-booted the computer, and that fixed the problem as long as I didn't enable Special Operating Activity again.

I didn't see anyone else reporting this problem during the contest. Am I the only one who was seeing it? During Field Day many were reporting it. Is there a work-around? Thanks!

73,

John, K9MM

John,
I had much the same problems until I ran a #12 wire ground from the transmitter to the frame of the computer. My computer does not have provision for a ground, but I put a ground lug under one of the power supply mounting screws. Run the ground wire from the computer to the Icom and to the antenna tuner and see if the problem clears up. The ground wire should go to a good driven ground rod.

I suspect a basic antenna problem, which is the lack of a dedicated return for antenna current. If we don't provide a return, Mother Nature will find her own, which may be through your ham shack and interconnected equipment to the green wire on the power line that equipment is plugged into.

Common dedicated returns for antenna current are radials or a wire counterpoise that can be in the air or laying on the ground.

In the shack, most RFI problems can be eliminate by proper bonding. N0AX has written a fine ARRL book on the topic of Grounding and Bonding, to which I contributed extensively. On my website is a pdf of slides for talks I've done at Pacificon, Visalia, and to several ham clubs. It includes a lot of conceptual drawings about how to do it right.

http://k9yc.com/GroundingAndAudio.pdf

Yes, ferrites can help, and for HF, 4-5 turns should be wound through a #31 core or clamp-on. But don't let that prevent you from doing proper bonding, which has the more critical result of greatly reducing the likelihood that lightning would destroy your equipment! Proper bonding is pretty easy and inexpensive -- all it takes is wire and our time to do it!

John,
most likely your RFI is hitting the USB interface between PC and TRX. You should use a USB cable with double shielding and RF chokes an each end. If this does not solve the problem try to connect the shield of the USB connector at the PC side to the tuner chassis by means of a ground clip which is common for scope probe tips. My TX power can now go up to 500 W without affecting the (notebook) PC.

I think you are on the right track.
I have ferrite chokes, mainly clamp-ons, on every lead into the computer and also on any power supply or connecting leads, mains and PSU. If possible I use several turn inside the choke.
My equipment is all connected to a single earthing point which ultimately goes to an external earth with 3 4 foot grounding rods in the garden.

I had RFI, but can now run 200W SSB into any of my antennae without problem.

This, like others, is a case where having a field strength meter would be very handy to have.

Do you have all of your equipment bonded to ground? Pwr supply, radio, tuner & computer?

One assumes you are bringing into  the shack the longwire ant. as a single unshielded wire? I.e. not coax...

I have a friend who did that, had the same issues. He solved the problem by using a 20-25 foot coax cable to a 1:1 current balun with the ant. Wire to the center & the ant side shield going through a wire back to the ground.

Not only did his rfi go away, but he cut his noise floor by by 3 or 4 S units.
