Hi All!

 Our club plans on using CT 8 for Logging during Field Day this year.. I was
wondering if their is any new Data files for Version 8 for the FD?? I know
that there was once a CT mailing list but the address I have for it is

Thanks in Advance..

Speaking of radial wire, I need about 5000 feet of insulated wire for a new 
80M 4 square array.  I'd prefer number 16 or larger.  Can anyone suggest a
source, or obtain it locally and arrange UPS shipping to me?

There was an hour-long special on lightning on The Learning Channel
yesterday evening (Science Frontiers).  One of the segments dealt with 
a mountain-top lightning research facility in New Mexico.  Apparently 
the place is situated amidst an area known for the frequency of its 
lightning strikes. Part of the work there is to test various styles of 
lightning rods, side-by-side.  The on-camera staffer claimed that it was 
very unusual for lightning to strike _any_ of the tested lightning rods, 
despite their prominence.  Go figure.  Anyhow, it was an interesting program,
especially in light of recent discussions here.

Doesn't it matter what band you are considering?
(Pardon me if I don't remember the start of this thread)

I agree completely with Bill's comments below if you are talking about
40 M and up, provided you have a support for a dipole/inverted V.

But, it seems to me that 80 is dependant on the height of support you can acheive 
and 160M more so.  I know that it also depends (on 160 especially) on band
conditions - there are times when the angle is higher and dipoles do well and
times on 160 when only the guys with vertical antennas (Inv L's etc.)
get out.

Note that a 160 dipole at 60' is the same part of a wavelength above ground
as a 10M dipole at 4 feet.  I know from experience that a 160 dipole at
60' has trouble working long haul DX, although at the bottom of the sunspot
cycle almost any antenna can get out.
