Flashed to Skylark 4.4 today and it all went exactly as expected. v4.4 worked much better than v1.2. I was unable to connect to v1.2 (even after following advice from the forums), so I flashed back to v1.0
I like v4.4. The Tuner app seems to update the current file upload better (in v1.0 it didn't seem to update the current file being uploaded.) Also in v1.0 I seemed to get way fewer files than what other people were getting. After updating to v4.4 the files seem to be coming in much faster.
For both v1.0 and v4.4 I am getting the same SNR of about 6 - 8 dB (depending on weather conditions) (off 144E).
