[aprssig] TNC-x

Is it installed between the base of the transistor and ground?  That's a
configuration I've seen in a number of circuits, TT3 included, and I copied
it in the OpenTracker.  Seems to work fine.  I buy .1uf caps by the
thousand, now.  =]

Well, I found the solution... I moved my .1uF cap from the radio plug
all the way back to soldering it onto the leads of Q1, the PTT
transistor.  Working fine now.  Now to get deviation set.
