I'm experiencing a new problem this 160M season. (I don't
listen to top band at all during the summer, so I don't know
when this problem started, other than it wasn't here last year.)
I have STRONG buzzing birdies (not a single tone, but a raspy
buzz) that occurs every 7 kHz, starting around 1700+ kHz and
goes up to about 2700 kHz. It's loudest right in the 160M
band, 1800-2000kHz. (Not because of a resonant antenna
measurement, but as observed on my beverage antenna.)
In band, on my TX antenna (shunt fed 110' tower), the buzz
is S9+10dB. It's S7 on my beverage.
I've shut power down to the majority of the house and almost
all items in the shack, so I think it's outside my property.
Any ideas?
Thanks,
Chad WE9V
