I apologize to those folks calling me on Topband during the contest. The noise
level was very high. No receive antennas on a very small lot. And the back
scrub area where we would string up a beverage had just been cleared.Only 25

I may have been dreaming, but I thought someone came up with a newer combiner
that included chokes right on the circuit board instead of making external
chokes. I have had no luck so far doing searches. Does this ring a bell with
anyone?TnxN2TK, Tony

I have an 80' Rohn 45 tower that I shunt feed. At 85' there is a SteppIR
MonstIR. I set it on 7020 when I want to transit on 160M. The setting of the
antenna has a dramatic effect on 160M with SWR.
I have side mounted antennas at 45' and 50'.
The shunt feed is a set of three parallel #16 enameled
I use a zinc ground clamp on each tower leg to attach the tinned #4 solid
copper ground wires.

changes etc. I think the two-hole BN form is way more mechanically
robust than the skinny rings but I have broken both kinds due to mounting them
"too tightly down" to a PCB.

Hi Mark,
Both of my BOGS are right on the ground. One works fine. I was referring to the
signal level being low. I swapped boxes just to very it was only the feedbox.
It is only the feedbox.
Just surprised why all the tiny pieces and yet the primary and secondary #30
wires are fine.

I use BN-73-202 cores for my receive antennas - Pennants, BOGs.
Finally getting time to check out my receive antennas. One BOG was very low.
The BOG transformer was broken. I mean it was totally destroyed. The largest
piece was 1/8" long. The primary and secondary wires, #30 were intact and

What do you
I shunt feed my tower on 160M. The feed is about 4' above the base of the
tower. I use a vacuum cap beta match. I use three vacuum caps. I have a
vacuum relay to switch between high and low 160M. The coax from the shack is
all underground to the base of the tower. The shield of the coax and the
mat
First QSO with Herb was in Feb, 1981. Still have the QSL card.

Sorry to hear about Herb. He was my first DX contact on topband. H
Lee,
Tnx for the info and taking the time for the test. The differences are in
the noise level.
Stay safe

I have a pair of Pennants and a couple BOGS. The Pennants I dual feed. At
each end I have a small box with a terminating resistor, relay and BN-73-202
binocular core transformer. I feed 12V through the RG6 which is all
underground to select which direction. Without 12V the relay is not
energized t
worked well at H40TT on two DHDLs and we had some T-storms nearby

I am making up new boxes for my Pennants. I will be switching directions
with a relay in the box besides the terminating resistor and the choke.
My question is what are the correct values of the components for feeding the
12V? I will be using this only on 160 and 80M.
For the coupling cap betwee
x27;s abt 8' high. My point is give it a try might surprise you. Also kave a
K9AY loop and at times it's better. Fred KB4QZH

Has anyone had experience with this system and have done a comparison to
other receive antennas? I have room to put up a BOG about 200' long at a
right angle and about 100' away from my present BOG. But it would be
difficult to get the feedline to either end of the wire. This system looks

Gary,
Thanks for the tip on the Permethrin to get it in large containers at an
affordable price. Looks like dilution is about 1:120. One 1.25 gal should
give me one coverage. But can't be shipped to NY. Need to ship to a buddy in
NJ or PA.

A neighbor had released a number of Guinea Hens that kept increasing in
numbers over the years and did a fine job with the ticks based on the white
towel method of checking for ticks. But the coyotes came and had some good
dinners and now no more Guinea Hens.
