[Wswss] [PNWVHFS] Re: Loud Carrier On 52.525 MHz (The 6 Meter FM Call Frequency)

If there is any new road construction within a couple mile radius, look for the solar charged roadside info signs.  I found the computer unit emit RF all over the HF, 6 and 2M bands here.

 

I arranged to meet with the operators and we opened one up and I put large snap-on ferrites on the interconnecting ribbon and power cables to the computer unit.  It helped some, but also asked them to shut off the computer unit while it was not being used.

 

In my case they would store them on personal property behind trees and bring them out for certain traffic controls so they were a moving and invisible target. One day I drove by a unit with my radio on. At home I could verify the direction on the beam antenna, then later took out the FT-817 and a portable beam and traced it to the storage location they rented from a property owner.

Pete:
Good luck finding  this and let us know what it was.  A few years ago, in the Spokane Valley at my station, during Christmas, some Part 15 unlicensed device started a raspy signal going up and down 6 meters and I figure it was a Christmas toy.  A few weeks later, it disappeared as it probably broke from use.  Thank goodness for quality standards.  Being surrounded by 17 other houses, I heard many Part 15 49 MHz phones as well as other mysterious devices.

For the past couple of days, I have noticed a continuous, loud, carrier on 52.525 MHz. There is some audio on the signal, but carrier frequency is stable. I think that the station is vertically polarized. On a scope, the signal appears to be about 3 KHz wide with 3 distinct peaks. I do have a jpeg of the scope display.

>From the middle of Thousand Oaks, CA ( grid DM04ne), it appears to peak on a heading of about 120 or 300 degrees. 

The signal exhibits flutter when an aircraft flies in the vicinity of my home station.

When driving my mobile around town, the signal exhibits typical mobile flutter.
 
I do not think that the signal source is in Thousand Oaks.

Please listen for the signal and post your results and/or send to me at N6ZE at arrl.net

52.525 MHz FM is the 6 Meter FM calling frequency and should be left clear!
