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

Read Palomar Engineering online RFI issues. Consider wrapping cables around ferrite toroids as well as using snap-on chokes Regards, Joe Ellis KN5Y

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

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

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

Seems like I remember seeing a technique to transferring a contest to ADI file. Is it possible? Thanks and 73 Rod W7OM

Also... put about 3 to 5 ferrites on the coax near the tuner & on the patch coax between the tuner & radio. 73 - John - N7GHZ

John 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

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

I am new to the digi modes and am slowly both figuring this out and understanding how it works. But I suspect that I have getting RFI into my computer causing problems. I am using an IC-706MKIIG

Geez Louise. I guess I "ZONED OUT". I didn't even know there was a difference between an ITU and CQ zone, figuring that they were a different way of saying the same thing. Thanks to everyone for

Ed, I have followed with interest this discussion. I have not seen which rig you are using and how its audio is connected to your PC. Also PC operating system may be an issue. All seems to indicate

I have finally got my transceiver and computer talking to one another and WSJTX seemed to be working alright. However, I got a number of errors. " Running C:\WSJT\wsjtx\bin\user hardware 10 ( also

Hi Ed, what are you using for PC clock accuracy? 73 Bill G4WJS.

Bill, Two additional observations. Under these failing conditions the decode count on the main WSJT-X window remains at 0 regardless of the number of signals on the waterfall. Second, JTALERT doesn't

Hello, Please disregard this message. I was looking in the wrong place for the files. I apologize for wasting anyone's time. Ed W2GHD

Just to add Bill, I have seen many times the cq and out zones are reverse in qrz. Not sure if qrz or manual input is causing issue. I have corrected several in my log sent by my LG phone

Unfortunately there are two radio amateur zones CQ Zones and ITU Zones, that have different numbering. In CQ Zones Mexico is number 6. 73, Reino OH3mA

Bill - Thanks so much for responding to my question. Since you asked for an example, take the following CQ message: 045330 -11 0.3 1143 ~ CQ HC5EG FI07 CQ Zone 10 HC5EG shows up in QRZ as being
