this isn't the right place for doing tnc changes, but before I forget to change it...

dj2ls 93c12d642d updated Hamlib integration
moved back to system integration. It seems we need to have a look at the hamlib library pathes on linux distributions. They differ from version to version

DJ2LS df38ee01ba gui & tnc improvements
displaying now frequency offset and frequency in heard stations. Decreased size of receiving audio buffer, which seems to optimize RX
2021-10-24 14:44:55 +02:00
DJ2LS ef31935ade disabled offset correction closes #81
we are disabling this to avoid confusion. Maybe we will enable it somewhen later...

DJ2LS 6eae5604d0 reversed offset fix #81 2021-10-13 19:53:47 +02:00
DJ2LS 655d333af2 freq offset handling #81
first attempt just with pings. Station A sends a ping to Station B. Station B is detecting RX offset, adds it to the ping acknowledge frame and sends it back to Station A. Station A will then adjust the frequency

DJ2LS 2d18767fe6 bug fix closes #78 and network optimization 2021-10-05 21:03:15 +02:00
DJ2LS e7ccf42ec3 modem optimization
optimized chunk size for audio data. DATAC3 should now work and overall SNR is optimized since we have less biterrors beacuse of losses by simultaneous buffer allocation
2021-10-03 16:31:34 +02:00
DJ2LS 8b08cc6e6b stop transmission
first attempt with stopping a transmission after the processing the current burst. Logging is a little bit ugly at this point, because it looks like a frame got lost. However, the transmission stops. CLI output is only visible for people interested in debugging...
