The FCC does not require the encoding to be "public domain", they require it to be "publicly documented". If it were public domain that would mean that any mfg could freely incorporate it into their own product.

Except when controlling spacecraft where codes to hide the meaning *ARE* allowed.

ยง97.211 Space Telecommand station.

(b) A telecommand station may transmit special codes intended to obscure the meaning of telecommand messages to the station in space operation.

You are correct, but the discussion was abut privacy in voice communications, as I read it. Smiley

I don't know about D*Star but back in the day they used to say that there was nothing more private than 220 LSB at the top of the band. Smiley

shoot, just tune down a few mhz on 2 meter fm or one of the odd ball simplex channels in the 145 range and you can be pretty much assured nobody is going to be listening to you. no garentees, but scannerland is going to have the local repeaters and '52 programmed in.
we use vhf packet to transmit information to and from hospitals and emergency centers. it's not coded, or encrypted, but the casual listner in scannerland prolly wont have the decoding software. but they could, free on the net about everyplace.
peace, everyone, ImAHam...
