bien hecho!

hola ANgazu and group,

this HARRIS PSK8 serial is another 106.6ms ACF waveform (frame length of 256 symbols, since the common 2400Bd speed). Like Arcotel-MAHRS, it does not use Known Symbols inserts (ie mini-probes) and is the only one to have a preamble of 60 symbols instead of 80. Decoders ...

Muchas gracias ANgazu

Hola ANgazu,
señal interesante de hecho!

un abrazo virtual para todos ustedes y un deseo de Feliz Navidad

Un fuerte abrazo de Italia a todos los amigos ... y vamos, los mejores tiempos volverán!!!

great works guys! WHARQ are really a nightmare. I read your analysis and agree: WHARQ family expecially have numerous waveforms according to the bandwidth, datarates and modulations.
We have to wait until Harris will publish some internals, in the meantime we just have to monitor - record - analyze ...

great catch! I tried all the KiwiSDRs in North Caroline just this morning... but w/out success

hola ANgazu

I agree with you: I have never seen WB handshakes or ARQ bursts (!!!) either, so possibly they emulate both spectrum sensing reply and ARQ.
And... yes, the lower bursts are probably WBALE, i.e. the Harris implementation of 188-141D extensions for 3GWB mode (indeed, those extensions are ...

Me disculpo por usar ingles...
The upper bursts are STANAG-4538 BW5 and BW6 compliant, most likely used only for link management. The unid lower bursts have a duration of 530ms and 1216 PSK8 (2400Bd on-air) symbols. These unid bursts consist of a preamble of 256 PSK8 symbols (768 bits) followed by ...
