dj2ls a90abb122f enable/disable cq response 
Enable and disable CQ response via GUI. Also moved settings to settings modal - with a small redesign. Auto updater still WIP
 2022-04-18 17:17:53 +02:00
dj2ls 88149830df first test with 6bit gridsquare encoding 
same for grid as call - we should think about saving the callsign and gridsquare as string and not as bytes. Also increased disconnect burst number where a toggle loop occured...
 2022-04-17 22:30:15 +02:00
dj2ls 53af74f757 first test with 6bit callsign encoding

Uses new QRV frame rather than new BREPLY frame. Also changes CQ
behavior to send only one frame instead of 3.
NOTE: This implementation will respond *three* times to previous release
software (v0.3.3-alpha.3 and earlier).

dj2ls 34cf0a4b05 cleanup 2022-02-19 20:45:57 +01:00
dj2ls 879ba00137 search for chunk from end 
according to the last commit we are now searching for data chunks from the end of the existing data. If a data chunk exists twice or more in our already received data, only the last one will be replaced
 2022-02-18 10:04:00 +01:00
dj2ls 6e0796f5a0 protocol adjustment 
if we are loosing a burst ACK because of fading signals or bad conditions or just because - combined with a changing speed level -  theres now a good chance we are not loosing the entire data frame because of a corrupted CRC, anymore. We are now searching in already received data, if our new (smaller) data chunk already exists. If so, we are stripping the entire data to this position and adding our new data chunk. If not, it seems we received new data the regulary way. However, this could cause problems if we have a too small data entropie. We might also check if we have an increased NACK counter or if a data chunk exists, twice or more -  in a further step
 2022-02-18 09:58:49 +01:00
dj2ls a8d1d576ad sending twice before lowering speed-level

dj2ls 3a072a63a6 removed buffer management for N>1 frames per burst 
I decided removing this from the code and keeping everything simple for N=1 frames per burst. N>1 frames per burst need a completely rethinking of buffer management.
 2022-01-05 11:38:39 +01:00
dj2ls 6a4fe14377 more debugging and buffer changes

dj2ls 3501b4f952 waiting for buffer 
it seems we need to wait a little bit for our modulation data. There are some moments where audio output is stuck a little bit. Maybe python is sometimes faster than the buffer allocation or its a threading problem
 2021-12-26 18:41:43 +01:00
dj2ls 88a0628b53 removed compression, incread callsign set time

data handler is now ready for chat messages. I updated the data frame with an additional information -datatype- so we can determine if we received a file or a message.
