Re: TNC options?



This is a great question, I'm interested in the answer as well.  If I 
can slightly hijack the question and expand it to radio choice as well. 
What are the best radios for general amateur satellite work?

The IC-910H looks great, but is it overkill for amateur satellites?  It 
seems like a lot of transmit power for most applications. Does you lose 
anything by going with something like the IC-706MKIIG?  I would really 
appreciate some expertise on choosing the right radio.
