Packet radio is an open standard, supported by multiple vendors. To get on packet, you will need, of course, a radio. Most packet happens on 2m, but some happens on UHF and even down to 40m as well. Most packet happens at 1200 baud (bps). On HF, it tends to be 300bps, while some UHF links run at 9600 or even faster.

HF PACKET radio is an FSK mode that is an adaption of the very popular Packet radio used on VHF FM ham radio. Although the HF version of Packet Radio has a much reduced bandwidth due to the noise levels associated with HF operation, it maintains the same protocols and ability to "node" many stations on one frequency.
