Hello Topbanders
I would like to explain my noise issue to get opinions on search and Destroy
This noise is covering the 160m band only, 80m is good ! I'm using a
HI-Z receive 4 SQ and the NW direction is as quiet can be . All other
directions are noisy with the NE being the worst , SE almost as bad and
SW is somewhat OK. The noise starts at 1780 Khz and rises quickly to
its peak at 1820 Khz ! from there the noise levels off to 1880 Khz and
slowly drops to nothing at 2070 Khz ! Wish I could post a screen shot of
my panadapter for y'all to see, I'll be happy to send JPG file off list !
I was thinking maybe water in the RG6 and with the Bias T the Hi-Z uses,
this may be my problem but disconnecting and testing all the coax using
the 20meg scale ... all checks good ! I may replace the RG6 anyway but
thinking of running a beverage at 165 degrees and see if the noise is
still there . Was going to run the beverage anyway in hope of hearing
Heard Is .
At first I was thinking power line noise , I checked for noise using a
144Mhz AM receiver and 3 el yagi . I did find some noise to my NE but
gone today after the big rain . 160m noise is still with me!
Now I have parts ordered to build a small 160 loop . With that and my K3
I'll move to different locations and see how that works out .
Yes I have unplugged everything in the house and no switching supply's
that we leave plugged in . With computers off and using VFO I can see
the S meter rise and lower sweeping through the 160 band .
I've ask 2 of my neighbors to disconnect their elec fence with no joy .
I have to give my pasture a couple of days to dry out , then I'll run
the beverage and replace the RG6 on the RX 4 SQ with new flooded coax .
Oh and I also tried a BCB filter ..
Any Ideas what could cause the 160 only noise ?
Thanks Ed N5DG
