Grounding on both ends of wires might work -- but two electrolytic capacitors works better across the power cables at the noise generator (i.e. charger/converter).  Chokes don't do as well and aren't broadband enough.

Hi Willie,

AC/DC wires to solar panels should be installed as those were antenna feeder
lines. The RFI is mostly due to common mode currents. One method is to use
braided cables with proper grounding at both ends.

Ferrites are normally used to prevent common mode currents i.e. both power
carrying wires go through the ferrite and the differential mode currents
cancel each other in the loading of ferrites.

Hi All,

installed FLdigi and attempted to get it working right and it messed up
WSJTX and SDRCONSOLE. I've spent hours uninstalling, reinstalling, etc. to
no avail. I now have OMNIRIG 1.20 installed instead of 1.19. and installed
the latest version of WSJTX. I've tried 64 bit and 32 bit but both won't
work.

Radio: TS-590S

When I try to start WSJTX I get a couple of pop-up error message boxes and
then the whole thing crashes. The errors say:

Rig Control Error Do you want to reconfigure the radio interface?

Error in Sound Input An error opening the audio input device has occurred

There have been no hardware changes. WSJTX interfaced and controlled my
radio great through OMNIRIG, but now nothing works. I wish I wouldn't have
messed with FLdigi.

Has this happened to anyone else or does anyone have any suggestions?
Even though I uninstall WSJTX, after I reinstall, all of my setup data is
in the program so there must be some residual files that are left on the
computer and not uninstalled.

Thanks for any help. Also, in case someone may know the answer,
SDRConsole reads the signal from my Airspy HF+ Discovery and can control my
TS-590S but the audio output from SDRConsole now comes out of my desktops
internal speaker instead of the studio monitor plugged in to the computers
soundcard output like it used to. I've tried changing every audio setting
I can find on the computer and in SDRConsole but nothing works. I realize
this is a WSJTX forum, but thought I'd throw this in as both of these

Happy New Year!

Hi Guys can anybody help?
I have just started to use wsjt-x to test long wire in a very convoluted configuration.
It is now located in a very small attic after the housing association cut down the tree I had put a stealth long wire into.
Running wspr to give me a rough idea of the radiation pattern I am now getting with the wire in this new position folded through many 90 degree turns.

wsjt-x runs for a while then I receive the following error.
Running: C:\WSJT\wsjtx\bin\wsprd -C 500 -o 4 -d -a C:\Users\merrittjd\AppData\Local\WSJT-X -f 1.836600 C:/Users/merrittjd/AppData/Local/WSJT-X/save/211231_1416.wav
Cannot open data file 'C:/Users/merrittjd/AppData/Local/WSJT-X/save/211231_1416.wav'.

When you click ok to acknowledge the error message wsjt-x closes.
From taking a look at the directory that the file wsjt-x was attempting to read resides in I could not find the specified file, so I can only assume it failed to create it in the first place?
I am using the NetTime timer, not the basic windows timer.
I have wstt-x running on a Windows 10 Desktop PC.
The HD it is writing to is new, as I only just replaced the old one about a week ago.
Radio is a Kenwood TS 2000 used with a SignaLink USB.
Thanks, appreciate any help/advice given John M0HSZ

FYI-

Consider too what Windows11 will support. To my surprise my i-7 6700 (4 core) 32gb machine fails the upgrade requirements for windows11.

Having worked for Intel a number of years I can simply say as most folks figure that Microsoft/Intel market upgrades this way.

So consider your requirements as Windows 10 will be slotted for an EoL date, tbd. Too bad for a great processor will become obsolete as well.... but then again we have Windows7 users who will not let go of their machines because of good running obsolete apps...

Sometimes it’s something that didn’t exist when the machine was purchased. Did you spec out that 10-year-old machine for wsjt performance?

I usually tell people to get the most machine they can, focussing on the things that can’t be upgraded afterwards. If the CPU or RAM or disk drive is soldered in, get twice as much as you think you need. Constrained as always by what you can afford.

If there was only one Best Computer (or car or anything) there wouldn’t be so many options to choose from.

CLUE:The 32 version was your pre-retirement original and you say that worked fine. I had problems similar to those you described when I installed the 2.5.3 64-bit download, updating from 2.5.2 64-bit which worked fine. Try installing the 32-bit version of 2.5.3 and see what happens. I know my computer has both the 32-bit and 64-bit versions of the VS-BASIC dll libraries, though it's way over my head.

I suspect some of the supplementary VB files have recently been modified by Micro$oft to work better with Windows 11, but that has broken the Win10 x64 compatibility. I have since downloaded WSJTx 2.5.3 RC7 win64, but have not installed it for testing because the 32-bit version is running flawlessly, replacing the original 2.5.3 win64 that was distributed first. In short, "If it ain't broke, don't fix it!"

There is a problem that when using mode FT4, WSJT-X disables the ability to use RRR.
As explained in one of the previous emails, even during a single QSO, the signalvariance within that short time period can sometimes be greater than 1 standard deviation. If the mean is -18 or worse and 1 standard deviation of -6 or worse, the mean may be actually skewed to the positive as you can't calculate with values that you never decoded.
Happy and a healthy New Year to one and all.  73,
