When the WSJT-X decoding suddenly stops). The FT8 reception «freezes» in my Windows-10/64-bit PC about once a day, for no obvious reason.ĭecoding stops, and the left vertical LF strength bar shows suddenly nothing (zero dB), even if the band is active with strong FT8 signals, and the PC clock is correct, and the Icom IC-756PRO3 transceiver’s reception is working OK (and has not been transmitting But with the newest rc1 (for Windows 10/64bit) Have had WSJT-X running continuously (often with FT8), and without any problems for weeks, with no interruptions. This helps a lot under such circumstances.Īnother problem, related to the newest Release Candidate 1 (rc1) of Version 2.5.0 of the WSJT-X program, is that it tends to «freeze» the reception once a day for me. In these situations I reload the web site «time.is» every minute to check the PC’s clock, and I press «Sync now» (or «Syncronize now») on the TimeSync program, if necessary. Strong 50 MHz signal is obviously playing tricks with my PC’s clock in a very strong RF field. This may of course also happen on other bands as well, if the RF field is strong enough.Īnd especially if the PC is a plastic covered lap-top PC, like mine.Īll cables entering the PC and the transceiver are made from shielded cable twinned around ferrite rings and/or ferrite clamps in each end of all cables. I am using Icom IC-756PRO3 with WSJT-X (now using Version 2.5.0-rc1) without any important problems with the WSJT-X (but see one problem reported below).īut I have discovered on 6 meters, with 1 kW power from a PA to a 7 element Yagi antenna, when pointing the antenna in the direction to the shack, my strong transmittedĥ0 MHz signal is affecting my PC’s clock! Then I may experience that I will not be able to get answers from other stations, because my PC’s clock gets out of calibration.
