Excuse me, could you please clarify what you mean by "APRS 30m"? Is it a reference to a specific music band or perhaps a radio frequency or technology of some sort? If it's a music band, I'm not familiar with that name, and it's not immediately apparent to me from a quick search. Could you provide some more context or information to help me understand what you're referring to? Additionally, if it's not related to music, perhaps we could explore other possible meanings together.

The transmission is characterized by a frequency shift of 200Hz, which is a common feature in High Frequency (HF) Packet Radio communications. This shift allows for the encoding and decoding of digital packets.
