I am trying to help an IRLP owner interface his GR-1225 repeater to an IRLP system. Mind you I am 1000 miles away, and can only help over the phone.
The problem occurs when he tries to operate full duplex. The repeater works fine on its own, and works fine when the node is operating in half duplex. But as soon as the External PTT is asserted on Pin 3 of the accessory jack, the RX Audio from Pin 11 is being muted. I have been looking through the help file for the WinRSS that runs the 1225 series, but for the life of me I can not figure out why a full duplex repeater would do this. The audio from pin 11 needs to be squelch muted, but why is it also being muted when the external PTT is applied? Can anyone come up with a solution? How would you ever be able to configure this repeater to use an external controller? Dave Cameron - VE7LTD IRLP System Designer
