As I mobile around while monitoring the output of my 224.18 MHz repeater as I have done for many years (it has been on the air since the late 70's), I have never heard any kind of strange signals on its output freq. or any 220 output freq. I have a 3 band Kenwood in the car and am used to hearing signals break the squelch on certain 2M and 440 frequencies, but never 220. The past few weeks, I have heard signals (CW, no modulation noticed) of a fairly strong nature break the squelch on 224.18 MHz, much like the signals that break the squelch on certain 440 repeater output freqs, which were eventually traced to cable TV leakage.
I am wondering if anyone else has heard signals of this nature on the 220 band? I know of three places within a few miles of my house that emit these signals. I am going to take my talkie out one of these days ands see if I can "home" in on one of these new signals. Roger W5RD
