Android FT8/FT4/CW for SOTA, with GPS time sync and a portable QSO logger

Hi everyone,

I would like to explain the idea behind FT8TW a little more clearly.

FT8TW is not only an Android app for FT8/FT4 operation. I also designed it to be a useful portable QSO logger for SOTA activations.

When I am on a summit, I do not always have a mobile network signal, and I usually do not want to spend time manually adjusting the clock. So FT8TW can use the phone’s GPS for time synchronization, which is very useful for portable FT8 operation.

I also added several features that I personally find useful for SOTA:

  • FT8/FT4 operation on Android, without carrying a laptop
  • GPS-based time synchronization
  • SOTA reference logging
  • ADIF / SOTA / POTA export
  • Filtering by mode and summit reference
  • QSO photo/log features
  • QRZ image lookup
  • Quick access to recently active frequencies
  • FT2 experimental support

So even when I am not using FT8, FT8TW can still work as a convenient portable QSO logger during outdoor operation.

If you try it during a SOTA activation, I would be very happy to hear your feedback, especially your radio model, Android device, connection method, and any problems you noticed.

Again, good job, was playing with it again today, a very polished app. Not sure why there isn’t more interest here, maybe the SOTA crowd are just a bit over FT8 at the moment.

Just now on 80m, acoustically coupled from my shack speaker to phone app…
