Hi Guys: Working on the 2nd 220 repeater project. I have been feeding audio out of my fob into the 'E2 - AF Input' pin of a newer T302 (220MHz) exciter. This exciter is replacing the former T301 exciter. My issue is that the limiter on the exciter seems to be 'a little suspect' - I can set it to ~ 4.8k one day; set my TX levels and then the next day, I find that the limiter seems to have drifted off up to around 6k or even higher! I have been using the E2 input for audio and E5 (modulator input) for PL tone. I am planning on moving the audio input to E5, so essentially feeding E5 with composite voice and PL. I did a quick search of the mailing list to see what others were doing. I was able to find three posts (from Bryan Fields, Robert Poff and Sam Nabkey) referring to an "audio mod". Is the "mod" just as I describe it above, or something more than that? I see reference to a series resistor of 4.7K, so presumably this is inline with the composite audio / PL output when injecting into the modulator input? Cheers, Ramesh, VA3UV
