I am in Northern California, Santa Rosa. For the past few weeks I have had some sort digital type signal at 10.223 MHz +/- 5khz and at 7.022 MHz +/- 5 kHz. Totally blocks out any signal. It is also found at 14.008, but much lower strength.

I have walked around my and house, turned off electronic devices, and walked my neighborhood with an old transistor radio that seems to pick up the signal at about 1020 kHz AM band. It does not seem to be local.

Anyone else notice this ??

Thanks

I solved my own problem. After a second walk around my neighborhood with my archaic transistor AM radio the pulse signal was centered on my house. A few flips of the circuit breakers got the problem to one of the bedrooms.
Unplugging items one by one got the problem to the cable TV box in one bedroom. Odd thing, the problem started about 2 weeks ago, the cable box has been there for several years. I am an active ham and this problem made 30m unusable. I could not hear most 30m signals. For the moment no TV in the bedroom, 30m is active, good trade.
