Even at low power on 80 and 40 rfi is getting into the software.
Using a Flex 6.5K BAREFOOT running any mode but really a problem with JT65-JT9 running WSJT-x 1.5.0
It simply will not allow me to do anything with SSDR or WSJT till that TRANSMITTED message is complete and the Flex returns to receive mode.
For example: Once a message cycle is started in WSJT, I CANNOT move the SSDR 'RF' or 'MON' sliders.
Now I have a single point ground. (2"x4" piece of copper sheet) mounted on the wall behind the desk and all things like switches, rf filters are mounted to this thick copper sheet which is connected to my water pipe ground. (all are in the same place so all interconnections are short and direct). Multiple ferrites are employed on all cables, power supply, keyboard, mouse, keyer. Basically anything that is wire and connected to the rig or computer has ferrites.
But still rf is causing SSDR to be unresponsive.
For instance, I can't stop sending, I can't lower the "RF POWER" in SSDR by moving the slider.
I can't lower the SSDR volume slider.
Basically SSDR is frozen and will keep transmitting till that message is completed.
I have always previously been able to find the RFI route and take steps to block it.
But this time I've been stumped.
So my question is:
IF THERE WAS A PATH THAT YOU CURED BY FERRITES OR MOVING OR CHANGING THE CABLE; please email me Bill@w9ol.com with your cure.

"which is connected to my water pipe ground"
Some water pipes, mine in a multi-unit townhouse is under (or inside) the concrete pad but "protected" by plastic pipe and has very little value as an RF ground. A friend's is a multi-unit vertical structure and the copper pipe has a long way to go.
A little more detail please as it sounds like a grounding problem.
. 1: as Stan said may not be a good ground because at some point it couples to plastic.
2: When you start running it as ground for you system you may introduce stray currents that can cause electrolysis and put holes in the copper. (I have seen that happen)
3: For RF ground it should be completely removed from the RF safety ground your electrical system.
I still struggle on 80 and 160 with some RF in the shack...at least I got 40 under control..
I run everything here off of a solar installation that is dedicated just to the ham shack. It runs everything in the room and none of it is grounded either. I do have lightning protection though. I only run wire antennas and use 450 ohm ladder line. For each antenna I have a steal plate with a couple spark plugs mounted on the plate. The plate is mounted to a ground rod outside and as close to the antenna as possible. Each side of the LL goes to a spark plug then continues on into the shack. The theory is If lightning hits the antenna, it will travel down the LL arc across the spark plugs to ground. Since there isn't any ground in the shack, there isn't much incentive for it to continue in this direction.
An added benefit is that it makes for a very quiet station. The noise level here is usually extremely low.
I do have an amplifier that I switch in line occasionally and it runs off of the commercial power. I do not have any special bonding to the amp and at 1500 watts - no RFI.
Palomar Engineers have some good solutions for RFI. http://palomar-engineers.com/
Hope this helps.
This put the high voltage part of the RF out away from the shack completely eliminating the RF in the shack. 40 and 80/75 were not a problem as the ground did its job even at 20 feet of 1.5 in copper braid to the ground rod. Any I hope you get my point to analyze your station setup as a complete system from antenna to ground using wave length as you guide.
Thanks for reading my long post.
