Maybe this will settle this. ** I AM WRONG. ** Period. So where is the MULTI_rx.py documented??? I've never seen or even heard of this. Or documented at all really. Its all just letting it trunk from a CC like a scanner......Or this mode with a center freq... So lets discuss what it can do... you mention multiple CC and multiple audio feed... > liquidsoap... Yuck not really a fan.. ....but anyway.... So lets start with 1 CC and doing MULTIPLE FEEDS???? How is all this plumbed together to get this my IceCast server??? Audio losses from "scanning" or this is queued up to feed in serial fashion????? One CC would need at minimum 5 feeds.... and how is all this audio held/queued up??? So if say 2 TGID's are active???? I can see issues trying this on a PI with the writes to an SD card right there. > , but the > penalty for going that route is having to deal with multiple antennas > (or a splitter) to try to capture an already marginal signal. I have a dedicated yagi to point to one system. And fed through LMR400, low noise distribution amp to provide plenty of ports. Same with my setup for more localized system on an omni, LMR400, low noise dist. amp and multiple ports. More than I need really. Basically its the same setup you would see at the rx end of a site.
