I'd like to correspond with anyone who has one of the new TAPR TNC's
or who has upgraded their Beta board to V 3.0 software.

The calibration routine won't light the LED's, so I had to calibrate
the modem using a frequency counter.  Some people have told me my tones
aren't the same loudness, but that could be rolloff in my transmitter
(ICOM 260-A).  Regardless, my deviation is too low so I'm in the process
of throwing together a preamp.

I can copy other packet stations with no problem, but they can't copy me.
I don't know if it's a software problem (least likely), a bad chip, such
as the VIA (a little more likely), or if I bollixed up the assembly (alas,
most likely).

I don't know if this is significant, but at power-up, the RESET and SPARE
LED's light okay, but the CWID LED lights at the same time, instead of
turning on a couple of seconds later, like the manual says is supposed
to happen.  What *does* happen is the RESET, SPARE, and CWID LED's come
on at the same time, together with the TXD LED.  The TXD LED turns off
a couple of seconds later and the sign-on message appears.

Also, is the RESET LED ever supposed to turn off?  Mine never does.

The ROM checksums are correct.
