Jim, sorry I responded to wrong person but thanks for comments.
Sniffing out RFI is almost an art form. I worked in Land Mobile Radio for 10
years and did a lot of sniffing in the 150 to 800 MHZ spectrum. I have also
done a lot on the ham radio frequencies.
It helps to have a step attenuator to put between the antenna and the
receiver when sniffing. I have also ridden with the FCC on one occasion when
they verified one of my finds and as a result the low power (1 KW) TV
station was taken off the air due to interference to Public Safety Radio
System (Cities of Norfolk and Portsmouth, VA).
Finding the interference in ham radio is only half the battle. Half the time
the home owner will not believe his home could be interfering with anything.
With all the new electronic gadgets and computerized appliances things will
only get worse.
73,

Ham radio active since 1954.

## I'm not the one with the issue. The fellow with the problem is paul,
W3PLP.
## I have done what u stated...exact same procedure.... .. but that was
along time ago... had to borrow a 12 vdc icom, since all my stuff runs on
120 /240. That was mid 80's.
## I don’t think that is his problem anyway. he has S7 noise while
driving in his mobile setup, within a 2 mile radius of his home.

Jim, have you eliminated your property by turning off your main power
panel and powering your receiver by battery?
If noise goes away bring power back one breaker at a time.
