First post, mods, if I am posting this in the wrong forum please feel free to move it. I searched for AM/FM interference on UHF and did not come up with much regarding this matter.
I work in an industrial setting. We have a UHF radio network for about 16 radios with 3 repeaters. Every component is older Motorola (HT1250-LS handhelds). Recently, I got tired of carrying the heavy, clunky radios which have quite poor performance. I was recommended the Baofeng UV-5R(V2+) from a friend. I purchased one on Amazon and have slowly been becoming a radio geek since. (studying ARRL tech book, taking exam in April)
Anyways, I programmed my radio to our six work frequencies using CHIRP. It works great, awesome battery life and TX/RX is better than the Motorola's.
I have noticed recently, that I was picking up music on my radio (on clear days). I thought maybe I had a bad radio for a bit but the other non-motorolas at our job site pick up the same thing on the same primary channel we use. The TX was so clear the other day, I heard the music stations call sign. I looked it up and it is a local AM/FM station which transmits on 88.1 FM and 1080 AM. We are using 457.525 Mhz as our primary work UHF frequency.
Any explanation as to why this is happening? Could this explain the poor performance of our installed radio system? Are our Motorola's RXing this but squelching it out possibly?
I am not really looking for a solution, but simply curious for my own sake. Any answers would be greatly appreciated!.
Thanks!
