[aprssig] PK-96 not responding

[Scott Miller]

I'm doing some 2-meter 9600 baud testing and had a PK-96 decoding my
TH-D7A just fine.  It wasn't transmitting right, though, so I tried
RESET and all of the lights but TX came on and it froze.  When I power
it up, it does that every time now and never gives a startup banner.
The reset button does nothing.

Anyone know how I can get it unstuck?  Or where I can find a manual?

Thanks,

Scott
