Just a quick heads-up on what the ARRL160CW looked like from my chair
(operating as EI100T from IO51uu near Cork); my log has just gone in with
the grand total of 4 QSOs ;-) About 6 hours in the chair split evenly
between Friday/Sat and Sat/Sun...
Thanks to the magic ears of W2BC, N4UA, K3ZM
Did anyone hear massive QRM around 6:00Z during the ARRL contest last
night? I've been trying to isolate a noise source but this was unlike
than anything I have heard since the woodpecker and it had a fast
attack like the woodpecker but was not the same sound. It extended
into 80M as well and
Mike, Im pretty sure a group buy would convince the manufacturer to sell
them. Supposedly an Ebay seller has an exclusive but since our use is non
competitive to his SWL and cave dweller ham customers it could be
negotiated.
The large diameter steel ones work well but rust away in 15-18
The same holds with loaded element yagis. Gain decreases due to RF losses
but directivity is the same using the same boom length and number of
elements as a full size version.

Many thanks Dean, Carl, Mike, Joel and the rest of you who shared your
opinions about why so many, probably
My 160 TX antenna is also my 130-foot-doublet. It's up about 80 feet and fed
with ladder line. To use on 160, I tie the feedline together at the bottom and
feed against ground as something like a Marconi T using a L-network match
right at the base.
The rest of this post is about our favorite
resistors. Id guesstimate the general F/B to be over 20dB on 160. My
feeling is that performance could not be duplicated by various other
loading methods. If somebody wants to make real world comparisons it might
be beneficial.
I looked at slinkys when I lived in Conyers. None of this is
If I wanted to measure the radial and feedline AC current, not having any
RF ammeters, I might just take a #47 lamp or other small pilot lamp and
stick it in series with the radial and transmit into it. 40 mA will make a
#47 lamp glow very dimly. Is this a good thing to check on?
Probably not
Topbanders,
thank you all for your advice and suggestions over the last days.
DL0WH spent about 10 hours in the contest , managed to log 48 qso,
scored 23 us-states (that is almost half the WAS over a single weekend!)

TX antenna, never gave me so much as a QRZ for the several dozen times I
called, and had his auto CQ set for a very short recycle time.
One of the reasons why people do the short CQ recycle is to
be able to hold the frequency. This morning a well known
op who should have known better sent ?,
After many frustrating experiences with unwelcome interaction between
various 160 antennas and towers, I am thinking about going back to
basics by removing all the other 160 wires, and shunt feeding the 110
foot tower (which has a number of yagis on it). All else being equal

I especially want to thank TM6M, my only EU contact for the

My L goes up 65' and the remainder of the 150' straight out. Worked
perfect 1st shot, no trimming. Length was recommended by Guy!

Martin, Carl and Bruce, many thanks for the graphics and suggestions.
I think I can install one temporally to compare the results of a 900 feet
against 600 feet.
Many thanks to all for sharing opinion and experiencies. Eddy, LU2DKT

Until recently, I was planning to put up an inverted-L as a TX antenna for
80 and 160. However, things have changed, and it no longer looks like I'll
be able to run the radials I would need to have an effective vertical. Now
I'm leaning toward a low dipole.

Hi Rick,
I've been down this same road as you - starting with a low (18 metre)
dipole, and after 1+ year of using it, I was only able to copy work
just (1) DX station from here in the Northeast US - that being DF2PY.
I couldn't even work to the west coast of the US with the low dipole.
Hi Rick-
In regards to copperweld near the ocean, here in California wire near
the coast, my copperweld has not held up too well as the steel rusts
then fails due to intrusion through any damage to the copper surface.
solid copper will last much better.
BTW I understand the utilities use
