48.74 mHz carrier
Hi Folks!
We have a licensed freq of 48.74 and every spring and fall, our FM radio picks up a weak signal in the morning. It goes on for hours. The last time I heard it, I heard a phone ringing through it. Not like a microphone sound of a phone ringing, but more like what a ringing phone sounds like in the handset when you make a phone call.. There is no PL on this signal, so I turned 'channel guard' on. It's now gone, but I still wonder where it's coming from. It must be strong, because three different radios, spanning over 100 miles apart, hear the same thing.. I jumped on Javaradio, but I couldn't hear it anyplace else.. If anyone wishes to reply with a signal report of this signal at a location, I'd appreciate it.. Thanks! Harry KB2MEN |

Could it be VHF lo-band "skip" on a baby monitor? Check to see if ten meters is open when you hear it. If it is, it's likely something skipping in on lo-band. Quite alot of fun back in the late 70's and early 80's. I was hearing fire dispaches from New Mexico and taxi companies in Jamaica from my home in Maryland with an Grove outdoor omni antanna hooked up to my scanner. Firefighters in the next county also used to operate on VHF Lo-Band for both dispach and fireground. When the band was "open" they would often exchange "radio checks" in the mid-morning once a week with 2 fire companies sharing the same frequency in the UP of Mich. and another in Kansas! They even exchanged their version of a QSL card in the form of uniform patches. Yes, the good ole days of 1st generation VHF Lo-Band radio was always alot of fun when the band was open! |

Hi: Thanks for the reply! It might be some kind of cordless phone, just that the carrier is always there.. I suppose some older units might work that way.. The frequency isn't right for cordless in this Country (States) but might be typical for some other Country.. Would be a great DX QRP sig report! 100mW or so.. The antenna on this radio is a ground plane verticle on a 300 foot tower that's on a 540 foot mountain in Jersey! It has outstanding coverage! Thanks! Harry |
