Hi all,
I just recently purchased a used ICOM IC-FR4000-3 (450-470MHz) repeater to use on the GMRS band as a community repeater. It powers on and I am able to read/write to the repeater using the CS-FR3000 software, I have programmed my desired freq and Tx/Rx PL tones and when I key up using my HT it activates the repeater and the repeater transmits but there is no audio just a dead carrier. I have check my HT's in talk around mode and can hear audio just fine so its not that. I am waiting on a mic to try and operate the repeater in base mode but it will broadcast the CWID and that can be heard over the air. One additional thing, it appears that it may have been hooked up to some type of controller and when I opened it up it has a Receiver Line Card (1RC) which is soldered into the accessory port card and attached to the RLC at Audio In, COR In +10-15VDC, and Ground. I don't think it is stock. Not sure if that has anything to do with it? I have tried some basic trouble shooting, adjusting the squelch, checking the power at +8V Reg etc. Not sure what the receiver line card is for either? Any help or suggestions in this would be appreciated. Thanks,
