Hi,
Have a P1820AX (VHF) repeater. Performed setup and placed the machine in "TRANSPARENT" mode. The machine will pass both standard
FM analog and DES type signals with no problems. Other repeaters will (MSF5000 & Quantar) when in "transparent" mode will pass Dstar.
The issue I'm having is the P1820 is not passing the Dstar signal. The machine does see the signal and will key-up but nothing is passed, not even digital noise. Any suggestions on how to get the repeater to pass the Dstar signal.

Joe,
You will need to change the mode of operation from Analog - DVP/DES to Astro - Digital in the repeaters software. You should read using the RSS for the P1821AX UHF software for all of the different parameter flieds to a printable file, bolding the info that needs to be changed in the P1820AX VHF unit. Remember these are basically portable repeater packages so the UHF version should operate without any major changes to the unit, in contrast, the VHF version has a minimum frequency seperation of 1.6 MHz between Tx to Rx Duplexers so you'll need external Duplexers capaible of the standard 600 kHz frequency separation between Tx to Rx for Amateur Radio operation.
Depending on the age of these repeaters, they could have either Astro V-SELP or the current IMBE Digital formats, where as the D-STAR uses the AMBE Digital format.

Dan
