RTK data rate and maximum age of corrections

Just a general question about RTK NTRIP data age and speeds - what is the oldest and slowest acceptable speed for corrections. I have a very slow RF datalink at 1200 Baud a wondered if it would work?

What’s your hardware setup? What’s the source of your corrections?

It’s not recommended to have Age of Differential higher than 5s.

It’s very theoretical at the moment, using RS+ and a M+ with an amateur radio link (packet radio). But with 5 seconds at 1200 baud would be about ~600 characters which I would think would be too slow. The range of a hamradio link could be easily >25 miles with just a few watts of RF. With hamradio it’s also easily possible to have a 9600Baud link.
