Greetings TopBanders, LowBanders and Those Who Aren't Sure,
The minions of The Boring Amateur Radio Club are pleased to remind
you that in roughly 2 weeks
from THIS WEEKEND the 21st Running of The Stew Perry TopBand DX will
happen. That is Dec. 17 &
18 for those with calendarphobia. After
Herb --
I don't have Beverages, but rather pennant antennas. I think we have potential
problems at both ends of the feedline and need protection at both ends. I use
Fair-Rite 31-material snap-on cores at both ends, and there's a noticeable
difference in the noise level if I remove either
You were heard very well in to Colorado last night. I did not get home
tonight to check.

As you were disconnecting the radials the ground losses were increasing
until it got to enough ohms and you had a good match at 50ohms.
My 160 T matches 25 ohms 1.12:1 at 1812Khz and is fed with a 50:25
transmission line transformer. With 8x 125' elevated radials the N6LF
research shows I

Yup, and some
This is normal, but without the radials your RF is mostly heating up
the earth.
If you make the L a little longer, then insert a variable capacitor at
the feed point, you should be able to find a higher feed point with the
radials connected..
With trial and error 'juggling' the extra
Hi allLast year i install an inverted L antenna for 160 with few radials
different lenght.ohms was between 20 to 25 ohms and swr about 2.2 . This past
weekend i was checking thethe antenna with the mfj analyser and i proceed to
disconnect the radials from the groundrod and just leave the ground
Olof,
I'm in AZ. SR at 1419z and SS at 0019z. I heard you on 80m CW yesterday
just before and during our SR abt 339/449. I have 3B9 on 80m so I didn't
call. However, many of us on the West Coast do need 3B9 on 160m. Anytime I
see a spot for you on TB I have listened when we might have
On my Beverage feed-line RG6 runs (some 200 feet) I use multi-turns a
large toroid on each feed-line and the attach each coax to a grounding
block and good ground rods (typical Hume Depot RG-6 variety) then on
the other side of the grounding block before the coax runs about 20 feet
to the
One nice trick I have used in the past to locate buried radials and
check them for continuity is to walk around the radial field with a good
professional FSM (field strength meter) tuned to station's transmitted
signal (at reduced key down power preferably to protect the transmitter)
and with
Hi Olof
Your signal was very good during the weekend contest 569 solid working
Europe, I called you several times one hour before your sunrise,. Yesterday
I heard you again on 160m with QSB and very weak signal. There was two peaks
one 20 minutes before your sunrise and a second one 20 minutes
You don't put down a lot of radials only for more return current; you
put down a lot also because over time you'll probably lose some of
them to damage or decreased conductivity or some form of disturbance.
If your radial field is uncontrolled, and you can't watch it
constantly, you may wind up
Following CQWWCW I am staying on in 3B9 through sunrise December 12th.
This is not a DXpedition in its traditional sense but I will try to spend a
few hours on the radio every day. So far 320 qsos logged on top band but
only 11 with NA. On 80 the log has 250 qsos with 82 NA.
Plan is to be on
