Id give it a 6.5. Europe was plentiful on FRI night, but with just
fair sigs. SA-CA-Carib fair. I tried very hard to work a loud LU8 with
no success!
No Asia. No Pacific. No Africa.
Thank you KL7RA!
Station: IC7610 - ACOM 1000 - N1MM+
Antennas: SAL 30 rx antenna. 52 ft tall 1/4 wave INV-L in a 40 ft
walnut tree with the horizontal leg running SE. All 27 radials (
30-130 ft long depending on PL) were neatly coiled up, hanging from
the lowest branches of said walnut tree. (Maybe I can lay them out
before this weekends ARRL 160m Test.)

Homebrewing a 9-circle vertical array, and I'm looking for opinions
from other 9-circle users on
what chokes you're using on the feedlines (rg-6) at the switch box,
and on the control line. I can go the
binocular core route with rg-174, as per W1FV's article, but would
prefer the simplicity of several turns through a snap-on choke.
tnx!

You can make a feedline choke with snap-on ferrites as follows: wind
4
turns of the feedline through 5 snap-on cores of Fair-Rite part
#0431176451.
The core has an inner diameter of about 3/4 inch and 4 turns of RG-6
is the
limit of what will fit in the core. However, using 5 cores will
provide a
large total choking impedance (~10 kohm) on 160. A larger core will
accept
more turns but at significantly more cost for the cores. The
advantage of
making chokes with RG-179 wound through smaller cylindrical cores is
the
much lower cost, although it's a bit more work to make these chokes.
