Listmates - after 60 good years in our hobby with more than enough rfi
sniffing and eventually eliminating I have met my match. I ventured
yesterday into my infirmed and mideighties afghan neighbors home which is
producing a roughly 25-30 db hash above my noise level on all bands. After
a complete house recon, I still could not locate the source with my trusty
grundig yachtboy since the whole house was so hot (rfi can be heard from
several hundred yards away) that I could not discern a specific culprit.
The owners who were a bit confused by my endeavor and our language
challenges said that nothing had changed recently except when a bathroom was
remodeled, the handyman replaced numerous wall outlets. So after more chat
effort, I shut down the house mains and the noise disappeared so I know the
gremlin(s) is hiding within. Not overstaying my welcome, I begged
forgiveness for the fruitless invasion but assured them I must come back.
My plan so far is next visit to shut down each circuit at the fuse box till
the noise is isolated and then attempt to sweep that area of the house.
Since my detective work must be short time wise and the rfi is so strong,
what possible source might I look for and hopefully be able to unplug
knowing that it pulses 30 times a minute continuously and sounds like arcing
to me with an audible preemptive spike at the beginning of each hash. It
begins as low as 85 khz and continues to pulse up to around 3 mhz where it
gradually becomes a continuous noise all the way up to 6mtrs. I trust that
some of you reading this postmightl have some guidance to share as I really
do miss being able to hear both my modern rigs as well as the fleet of aging
boatanchors. J 73 es bye4now, roger k5vrx
