Since the subject of "un-intentional radiators " has come up , I had one
appear about a week ago . 5 very clean very stable -80dBm carriers
4 khz apart starting at 1815.957, 1819.957, 1823.957, 1827.957 ,1831.954 .
Then Sunday evening at 0446 I moved my amp back to 160 and when I sent
my call , looked at the P3 panadapter and there was a comb
from at least 1710 to 1910 every 4 khz. I cannot swear it changed from
5 carriers to a comb when I popped 1500 watts out - but it is now on
24 hours a day.
It nulls NE/SW so is possibly from a new neighbor who seems to be running
a business about 250 feet away from my loop to SW - and I suspect some
sort of router.
Today I will wind up a ferrite rod loopstick for my R10 rx and go sleuthing
I cannot detect it anywhere except the 1710 to 1910 range - nil on 80 and above.
There may be some weaker stuff below 1710 but hard to tell .
Any gurus out there have an idea ?
Thanks
Hank K7HP
