PAW and FLARM, are totally different in this respect.
If you tune a software defined radio to the PAW 869.525mhz or FLARM (un-published) frequencies, you will get a series of bytes.
The PAW bytes directly represent the data held in the protocol, the FLARM bytes represent nothing intelligable (un-published) . This is because the FLARM data is encrypted using a set of keys which are kept secret (un-published), and should you be able to decrypt the data, the format of the unencrypted data is secret (un-published) .
So based upon this, is it really fair to question whether we are more open than FLARM ?
If anyone were to try to create a software defined radio implementation for pilot aware I would actively encourage this and help in any way I could. Unfortunately I do not have the necessary skills to do this myself
