I am working on getting a logic output to run my PL encoder for COR active PL on the main repeater port. using a variable i was able to get it to work fine with local RX audio. When a signal is present I have a gpio pin going low.. when not present going back high.. but can not find a variable to watch for IP links coming in. Is there one? Is there something I can watch so that I can make the logic pin swing..? Some google foo found these commands * 56 - Rx CTCSS Enable * 57 - Rx CTCSS Disable * 58 - Tx CTCSS On Input only Enable * 59 - Tx CTCSS On Input only Disable http://allstarnode.com/viewtopic.php?f=5&t=8 The only mention I see of TX PL is with use of a USB radio interface. Will *58 follow the tx pl settings set in usbradio if I had a USB radio device vs using one of the LOX ports for the main repeater.. -- Fredric Moses - W8FSM - WQOG498 fred@moses.bz
