Dead Air on 147.451

[adamfancher]

I'm listening in Barkhamsted and have a very strong signal that appears to be continuous dead air.

It's in the amateur 2m range but I'm not certain as to its current use, if any.

I have seen that in the distant past 147.450 has been used for weather balloons and space shuttles, but the ~1kHz difference is pretty far off from the peak I'm seeing at 147.4511 on the spectrum analyzer.

Thanks in advance for any information

It's noise from something. Perhaps cable leakage or some LED/CFL/Chinese Wall-Wart generating a nice RF spike.

147.45 is not used in in CT or the new England area for a repeater. I looked it up on the New England repeater Directory. This would be a repeater output frequency. The closest output frequencies are the K1SOX repeater in Woodbridge (147.5050 grandfathered -1 MHz split) and also a D-Star (Icom digital machine) in Newington on 145.3900. Also the frequency you listed is within the upper simplex split of the 2 Meter band. There is nothing close in MA or Eastern NY as well.

my cable box puts out a nice 144.0 signal
a small computer liked to tie up 121.5 AND 243.0
it is time to start unplugging stuff, and watch out that you modem does not have a small battery in it.
and now i would even include the washer/dryer and toaster !
