Well, things seem to get very quiet after my neighbour turns off his 30-40"
TV set, after the 11 o'clock news ! ! ! Otherwise it has been S8-S9 noise
every evening.  I am thinking fo trying that noise circuit in the latest
Lowdown !!!


I have several "octo-loops". A 7 footer and a 12 footer.
One picture at http://technology.fanshawec.on.ca/elec316/rigs.htm
That cross-piece is a 12 foot 2x4.
These are single turn, un-tuned loops, using a Burhans preamp
( made the PCBs ) and used them for last 6 years.
Very sensitive - 15kHz - 500 kHz - and very sharp nulls, so
can reject some noise sources.
At present, the 12 footer is held by rope, and suspended 25 feet up
in a big maple tree right in the middle of the backyard.
I have a row of 90 ft spruce trees to the South - about 60 feet away.
In the past I have mounted the octoloop right in the spruce trees, as
the picture shows, with no apparent degradation of performance.
I have usually mounted them on wood telephone poles at about 20-25
feet (at the bottom).
Good for NDBs from Azores to Arctic to 10 countries in South America.
7 footer is 1/2 inch copper, and 12 footer is 3/4 inch copper.

All fed with 50 ohm coax - and isolation transformers - installed at the
receiver end.
