Well, Speaking of EFJ PPLs, has anyone accually performed the repeater mods that are descibed on the repeater builder page? I have done one radio, but I am getting RF into the receiver. Jim Sharp (the author) mentions putting a shield around Q1, but the transistors are not labeled that way. I don't really see any EASY way to install any shield that would do much good due to the trace layout on the board. By-the-way, I tried to contact Jim Sharp and had no luck. Anyway, I am trying to use one of these radios for a remote receiver on 448.325RX and 433.050TX (radio tuned up fine). When the radio keys up, I get a squealing noise. Even when there is just squelch noise and no RX signal. It sounds like RF to me. If anyone has hints of ideas, let me know. Also I want to thanks Eric for the manual posting!
