R-8500, Trunker and the Optolinx
From The RadioReference Wiki
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. (insert image command here)
- The OptoLinx switch settings are as follows:
1 - Up 2 - Down 3 - Up 4 - Down
- The OS-456 board baud rate is set to 19200.
- 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:
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.
