Very grateful for your efforts, George. Would appreciate it if you could manage
to get on 160m earlier than 1100 - my sunrise is at 10.40!
Incidentally, you were a huge signal on 80m at that time today.

I have had good success (mostly) following W8JI's recommendations in a similar
situtation with over 3 ft of Beverages in very rough woodland:
Use electric fence insulators nailed to trees, but allow the wire to pass
freely through them;
Fix only at the extremes of the antenna;
Use a very

Your point is unclear to me. Of course the pattern of a horizontal antenna
changes with changing height and with other environmental factors. If the
antenna is actually on the ground the efficiency

Not really.
There is very little pattern difference between a purely horizontal dipole and
an inverted V provided that the angle of the V is not too acute. A horizontal
dipole 5/8 wavelength high has predominantly low angle radiation.
W8JI's experience with a horizontal dipole at 300 ft is often quoted as proof
that only vertical antennas are useful for 160m DX. This is not my experience
with a dipole with the centre at 320 ft and the ends at over 250'. In its
favoured directions it is equal to a W4RNL half wave vertical
May I politely ask that people do not make duplicate contacts with V84SAA even
in the contest. There are many of us for whom this is a marginal path, and even
a quick contest QSO could be enough to prevent our 'new country' counter.

I think that WD1-A would be perfect for on-ground radials. (Note that WD1-A is
not twisted although WD-1 is.)
It lays very flat on the ground, the critters don't like it, and it is
immensely strong. I always use crimp terminals but YMMV. I don't think it
matters either way whether you use one

I use WD1A wire mostly for (single direction) Beverages, but also as radials at
the ends of those antennas.

I am sad to report that Keith, G3RPB, passed away on the morning of Sunday 9th
July. This followed a severe stroke that he suffered last year.
Keith was a very well known and accomplished DXer on Top Band. I was honoured

Hi Steve
I am fairly confident that Sudbury counts as a cold place...
I have found Beverages to be very insensitive indeed to their locale and
operating conditions. (I have a total of 15, mostly phased.) I now use 4 x 50'
radials at each end, but have previously used 3 x 25'. I do not believe

I wonder if anybody has any that they would sell to me and could bring to

A few more comments seem necessary:
I do of course agree strongly with Greg ZL3IX. The only reason I am arguing for
a smaller CW segment is that there is very strong entrenched opposition from
the contesting community to any change whatsoever, and I am trying to be more
than reasonable.

I have received replies both on the reflector and privately.
Several suggest that the problem is that "160m antennas are narrow band". With
respect, that is an excuse not a reason. It is perfectly possible to match
(almost) any antenna at (almost) any frequency. People seem to manage it on

This weekend has seen the CQ 160m SSB Contest. It has also seen CW activity or
attempted activity from a number of extremely rare DX entities.

I have some binocular cores which I know are FairRite mix 73. I have others
which I thought were also mix 73. However, the first ones measure about 50k
Ohms with ohmeter prods onto their surface, whereas the others only measure
about 1k Ohm. I don't believe that that is a defined parameter, and
higher, you can be sure it is a different mix. The Q=1
frequency, where R=X or where loss tangent crosses reactance, tells you the
material better than anything else you can do.
That is how I quickly sort unknown cores.
