After not having used my IC-910H for a while due to moving across country, I unpacked it tonight and setup my antennas. I was able to make contacts on SO-50 and AO-51 with one small problem. I can hear signals on the downlink but not mine. When I transmitted, all I could hear was some white noise when I was transmitting. I head several exchanges but it was like I was in half duplex. This was a working system before the move.
I have good quality coax running from the IC-910H to an ICOM preamp for each side (VHF or UHF) and then running to the antennas. I believe that I have used all of the original coax but I could be wrong. The only thing I havent put in place was my mode J filter on the UHF downlink. Could this be causing my problem with not hearing my signal on the downlink but hearing those who are calling me ? Sorry for what is probably a stupid question but I am getting all the kinks worked out in my setup before Field Day.
