Can any newer radios support 9600 BPS?

You read about the many efforts to develop 9600 packet TNCs. All you need to make those work on the air is the "insert 9600 bps capable radio here." The issues from the past of frequency stability are probably better in 2022, (i.e. no crystal suppliers) but the TX/RX turnaround time gap is probably still front and center.

We have run a large (20+ node) 1200 bps packet network on 145.670 for 15 years, but "upgrading" it seems challenging. https://wordpress.com/post/hamtowertrailers.com/576

The actual public service use case in 2022 seems to be for mesh, (see audio, video, databases and dashboards) but packet is still fun. (This is not for Emcomm- whatever that is).

The radios I have seen/tested seem to be:

Motorola- finding legal programming software, out of band mods seem problematic

Chinese - heavily cost reduced front ends, and the use of one chip SDR - fine for voice- the precise analog wave form for 9600 to work may not survive (see the G.729 CODEC and analog modem traffic in the VoIP world)

Japanese Ham radios- is $699 an affordable price for these?
