As I said, house power turned off....so not originating in my house. No UPS' are running. Don't have portable HF...Hmmm..do have a TH-F6a...could use that , I suppose) No beam...run an off center fed dipole that is U shaped with the bottom of the U facing North by NE. (About 10 degrees from True North)

Kurt...I am in Reno...former chairman of the Wide Area Data Group. (and very happy to see what Jim, Steve, Don, Pat, and Tony are doing with the group! I pretty much stay away from VHF now...I am 95% HF and 5 % 900 MHz now. (Love the 9RS system) I can be found, pretty near every morning, on 3.959 around 8 am.

BTW today it's quiet today...5 minutes to noon and the noise is at 7 S units....was actually able to hear Gary in Yreka with no problems!

BTW..my days in S. Cal go back to the mid '60s...Claremont, where I got my first taste of sin as WN6RKN!

Sounds like a fun one to track down.

Have you isolated it to any particular area, for example, just within your
house or on your property?

When you kill the breakers, what else is running at your place with backup
batteries or a UPS?

30-40 over should make it easy enough to hear with a portable radio, can you
hear it in your house, and does it diminish when you walk away from your
place?

Interesting that it's limited to one band, possibly a single oscillator
circuit in a consumer device, did you change anyhting or buy anything new
when the noise appeared? What about noticing spikes, surges or brownouts at
the time?  I had a CFL bulb, which had been quiet for years produce noise
after a brownout, it was broadbanded, however, up to around 8 MHz.

Is there a piece of equipment that you turn on when it appears, or, if one
that is already on, one that you begin to use when the noise appears?
Sometimes things produce noise when they come out of standby mode and are
otherwise silent.

Your call sounds familiar, where you in the Pasadena area in the mid-90's?

Kurt
