When those boxes are checked, the values entered will be retained as the defaults for the next QSO to be logged. Unchecked, the fields will revert to blank.

FT8 decoding can use a technique called a priori (AP) whereby it uses naturally accumulating information for the purposes of increasing apparent sensitivity by about 4 dB. There is an increased chance of false decodes when AP is enabled since AP is essentially sophisticated guess work. The technique looks at its guessed result and compares it to the parity ...

For the current "77-bit" versions of FT8 and MSK144 (as supported by wsjt-x version 2.0, released in late 2018, and newer), you can use these callsigns without doing anything special. Any combination of letters, numbers, and slashes, up to 11 characters total, can be used as a callsign. If your callsign is "nonstandard", meaning that it doesn't follow the ...

My guess, looking at WSPR reports, is that, on average (median), WSPR beacons are transmitted at power levels maybe in the range of 10 to 30 dB lower than the median of FT8 transmissions. e.g. 20 dBm Raspberry Pi hat vs. 37 dBm QRP SDR, or 30 dBm WSPR appliance vs 50+ dBm desktop transceiver and/or QRO amp, as bracketing examples. So the reported 10 dBm ...

I'm not familiar with the failure modes of SignaLink devices, but in general, a USB device disappearing temporarily likely means that its internal microprocessor or USB interface chip has been reset, or the USB connection itself failed. The obvious hypothesis, then, is that your transmitted RF power is itself causing the problem by interfering with the ...

According to K1JT himself, the callsign field is rather restricted and must meet the same parameters as the one for JT65. https://sourceforge.net/p/wsjt/mailman/message/35254350/
