Can't use TCXO with odd frequency #183

Closed reiser4 closed 8 years ago

reiser4 commented 8 years ago

Hello, I'm trying to use a TCXO at 11.289600 mhz. Decode stops after about 0.7 seconds and I can't improve the situation acting on the OscOffset parameter. I guess the problem is the integer division by 24000 and 48000. Could MMDVM support my TCXO or should I throw it in the garbage and get a different frequency? thanks.

Tcxo supported are: 12mhz,14.4mhz and 19.2mhz or other integer division by 24000!!!

Grazie IW9GRL, avevo visto le frequenze suggerite nel file config, pero` chiedo se sia possibile in qualche modo ottenere una configurazione funzionante anche con valori leggermente diversi.

Some frequencies aren't possible because the division ratio isn't an exact integer. I don't know whether that frequency isn't suitable.
