Re: Topband: Noise on 160

[Joe Giacobello, K2XX via Topband]

Nick, I have been observing a similar signal for the past five months or 
so, but it's usually between 1837-39.  I believe that I've also seen it 
drift above1840 on occasion, but I don't usually tune in that part of 
the band.  I suspected it might arise from a local source or something 
in  my house, but I hadn't been able to identify it.  Listening on my RX 
4-square, it seems to peak in no particular direction.  Earlier in the 
year I had to install ferrite on the coax going to each vertical in 
order to eliminate some common mode pickup, but they had no effect on 
this signal.  Since I don't usually operate in that part of the band, it 
hasn't been a serious problem for me.  I can send you a screen shot of 
the spectrum and waterfall for comparison, but based on your image and 
description, it looks like the same thing.


73, Joe

Caught this interference around the FT8 freq. It's causing trouble from
1.8407 to 1.8417. Any thoughts? It sounds like a buzz and seems to zig zag
over multiple minutes. https://imgur.com/SgXeJGx

Topband: Noise Problem - 160 Meters

[Joe Galicic]

I have had this noise on 160 meters randomly appear for the past year.  Not 
related to weather or time of day.  When it started my neighbor told me he had 
some work done on his VDSL line.   I tried to get Verizon back out here without 
any luck.  I have sniffed around the neighborhood without any luck of finding 
it.   It is coming from the northwest of my QTH.  I can greatly reduce it's 
level with my K9AY pointed SE.  Take a look at the video and let me know what 
you think.  Thanks -Joe N3HEE
