I just thought I would send you a note and tell you my experience in
installing
Trunker.  This info might help someone else get the program running.

After going through the "Trunker" area on your web page I realized I
probably had
everything to make the program work.  The equipment I used was a PRO-2006
with
an Opto OS-456, an ICOM R8500, and an OptoLinx.  See attached bitmap.

Notes:
    1. The OptoLinx switch settings are as follows:
        1 - Up    2 - Down    3 - Up    4 - Down

    2. The OS-456 board baud rate is set to 19200.

    3. To use the AGC port you must set an internal jumper on the R8500
        to get the discriminator output (no soldering required).  This is
        documented in the R8500 manual.

First I connected COM1 on my computer to the OptoLinx serial port, next I
connected the AUX port on the OptoLinx to the AGC port on the R8500.


After reading the Trunker documentation I was able to get the environment
settings
close the first time.  The only setting I had to change was the slicer mode
from
inverted to normal.  Here are the settings that I settled on:

    TRACKSLICERPORT=COM1
    TRACKSLICERPIN=DSR
    TRACKSLICERMODE=NORMAL
    TRACKSCANPORT=COM1
    TRACKSCAN=OPTO
    TRACKSCANPARK=147.345
    TRACKSCANBAUD=19200
    NOEMERGENCY=1

After tuning the R8500 to the City of Baton Rouge control channel, Trunker
came up running with 99% accuracy (I don't know if that is typical but it
seemed good to me).

Next I connected Port A on the OptoLinx to the CI-V port on the OS-456.
Everything worked perfectly.  The PRO-2006 began following the trunk IDs.

I'm looking forward to exploring this new avenue in trunked system
monitoring.

Thanks for the great web page.
