However on checking the frequencies for RX/TX, I found it was very close, less then 1Mhz. For the channel they will be using, it is 476.425RX/477.175TX. I am sure the radio will be okay, however I am a little concerned on using 1 antenna, and running a duplexer. Question: can a 70cm duplexer be made to work at <1Mhz, and if so what type would he need? Any information would be helpful. Regards Kevin, ZL1KFM.   Yahoo!
