I got a Motorola MT1000 99-channel which I had programmed for the AAR channels 2-97. I keep mine tuned to Ch. 75 which is the NJT North Jersey Coast Line. Bay Head Yard about 6-7 miles away from my house but I can still hear the transmissions. But this morning, I seemed to only be RXing one side of the conversation only. Anyone have any idea why?
