The TZT2 manual describes the procedure to load a 'weather file' via USB or SD-card.
Assuming that 'weather file' must mean a standard GRIB file with file extension .grb, I tried that, but the file would not show up as a choice.
Loading weather files directly from the internet seems to work fine, but on longer passages I will not have direct internet access and I get my updated weather files on SSB via winlink. It would be nice if I could somehow transfer those to the TZTL12F. Any idea what the TZT2 would expect as a proper 'weather file'?
