Hi!, I have a F84 runing at 10 Mhz, it's a -04 part because here in my
country is almost impossible to find a -10 part, I've been tested it between
5 - 60 C temperature and it was Ok.
It's working actually as a packet transmitter only (it broadcast telemetry,
a cheaper version of a pager jeje), and still working 2 months ago, so...
don't worry, a couple of mhz more than the specified will not harm it at all!.

But keep in mind that what I am doing could be unstable, taking it to the
limit, It works and pass my tests but in a serious commercial aplication
would be better use -10 part.

so IMHO for 2 o 3 Mhz more, -10 part will not be necessary.

see you.
