Brandmeister master server will not forward encrypted traffic using privacy mode (at the protocol level). However if the voice is scrambled at the analog level, the server is unable to identify it as encrypted since it is just passing-through AMBE-encoded audio.

It is up to ham radio operators to check if such scrambling mechanism is allowed on ham bands in their country.

That is not true everywhere. I have official reply from Polish Office of Electronic Communications stating that encrypted trasmission between hams in Poland is allowed by Polish law. I agree that you can argue about the Over the air encryption that ecnrypts whole data packet vs ITU, but when it is DMRA 40 bit encryption always the source and target ID is not encrypted.

Can you elaborate is the behavior of repeaters connected to Brandmeister netowrk the same accorrding to incoming encrypted transmission?

How the brandmeister repeater will deal with: Hytera basic encryption (proprietary) Hytera Full encryption ( DMRA arc 4 40 bit = Motorola enhanced privacy) other non-standard proprietary dmr encryption standards?

Does the behavior of repeater depends on vendor (for example hytera vs hytera and motorola proprietary encryption)

While encrypted communications have places in certain applications, amateur radio is not one of them. With that said, encoded communications that use publicly available specifications (like digital modes) are allowed, but not encrypted communications that obscure the meaning of the message. Morse code is technically encoding, because you substitute letters with dots and dashes, but the key is a standard and is openly available. Making up your own Morse code that only you and a recipient have the keys for is an example of unauthorized hiding of a message. There may be some cases when what sounds like encryption is actually just encoding, but such transmissions still would have to occur on specific frequencies/channels and the identification requirement still exists.

Every transmition in HamRadio has to be decryted and open!
