Hi Danny and all.
Most of cheap CN radios build around "all in one chip" technology,
that uses direct-conversion receiver followed by weak DSP back-end to do demodulation,
filtering decided in most cases just for human voice.
And also that radio have not well builded front-end preselector to work good in real air
where a lot of other strong signal are operating too.
On my IMHO, simply there is no sense to look for that CN radios to use at 9600 packet!
There are still a lot of second-hand land-mobile professional radios from good
"old-school era" (1980's-90's) - Motorola GM, Kenwood TK, Icom F etc that also cheap now and
about every radio have "flat" non-filtered in/out pins on ACC connector, that is well for 9k6.
73, Sergej.
