Hi J.T.,
If your getting approx. 50% of 1's and 100% Recovery, then you have the
Polarity and Sound Level set just right...
When you press the Trunk button, it will start Searching automaticly from
there.

If you are seeing the Dump ok,  look for lines with the "CALL" statement,
if you are
seeing the Frequency as 800 or 900Mhz, then that is working ok.  If you are
seeing
some hex code like 0xNNN, then your trunking a system I don't have
configured yet.

Are the Trunk Groups you are trying to monitor in the 138-139mhz or 400Mhz
area?
  If so, then that is the problem.  If not,  and you are trunking a 800Mhz
system, then
try switching to "Splinter" for the Band Plan...

The "FSK" mode in the program, sets the Mode value to '4' as seen in the
public notes
of the PCR protocol as unused/unknown...  This is Narrow FM with Frequency
Centering
info turned off.  You will also see the Signal Meter having lesss jitter
than in FM Mode..
This is the mode that I suspect that the Darc32/UT-107 uses in Japan...
Still unverified...

The squelch setting on mine is set to about 9:45-10:00, compared to a minute
hand on a clock...

Hope you can start seeing results soon,
Jay
