Lucky hamradio and amrp is not limited to the USA so most of us do not
have to worry about the USA limitations.
In region 1 we got between 6 and 10 Mhz and usualy only 1 Mhz is in
active use leaving plenty of room for high speed data modes especialy if
FHSS is used.

There were a couple of them at DCC Atlanta last year and they chewed up the
70cm band. US regulations limit to 56kbaud per carrier within 100 khz
channel on 70cm. 97.307:
(6) A RTTY, data or multiplexed emission using a specified digital code
listed in §97.309(a) of this part may be transmitted. The symbol rate must
not exceed 56 kilobauds. A RTTY, data or multiplexed emission using an
unspecified digital code under the limitations listed in §97.309(b) of this
part also may be transmitted. The authorized bandwidth is 100 kHz.
