The oddcast encoder that Gordon sent me has a spot in the setup for stereo. I am feeding two scanner separated left and right.
You can buy an inexpensive stereo 3mm plug to dual RCA cable at any electronics outlet, then adapt to the mono 3mm plug out of the scanner.
Most of the scanner line level outputs are controlled from the "recording" flag in the programming so every channel you want to feed must have that flag set. I have had pretty good luck by using the ext speaker / headphone out and keeping the volume set low on the scanners. That will eliminate local listening to the scanners without turning the monitor feature on on the computer doing the feed. To mitigate having knobs turned and levels messed with I have placed my setup in a back corner of the basement on a dedicated computer (given to me by someone who was upgrading and wanted to get rid of an old 500MHz computer).
Do not use a discriminator out as there will be no muting between transmissions.
Most computer microphone inputs are mono, use an auxiliary input, if you don't have an external aux, the cables that go to the analog connectors of internal CD decks are available at most computer shops or even can be unplugged from the back of the cd in the computer. Put a stereo panel mount jack on it through a convenient vent hole in the chassis and set your mixer accordingly.
