HB9AK-1: 2m Packet Access with multispeed port

The 2m gateway HB9AK-1 has been upgraded for multi-speed access. In addition to traditional AFSK 1200, you can almost double or triple transmission speed by using faster modulations. This has become possible by replacing the HW TNC with the SW TNC written by Andrej/UZ7HO. This SW TNC can easily be used together with WINLINK Express.
HB9AK-1 will respond to the following modulations:
AFSK 1200 (center tone 1700 Hz) (standard)
QPSK 2400 (center tone 1700 Hz)
QPSK 3600 (center tone 1700 Hz)
BPSK 2400 (center tone 2000 Hz)
BPSK 1200 (center tone 1700 Hz)
The higher transmission speeds allow for faster message exchange in emergency communications. BPSK 1200 has been added for stations with marginal signals since BPSK 1200 is more robust than AFSK 1200.
Users are invited to test the different modes and check which one is most suitable for them.
Feedback most welcome!
