<< I didnt realize that there was such a small wind load capability
difference between <25G and 45G--  45G feels like climbing a ROCK compared to
25G to me--- Why is <55G so much stronger?

   Yes,  I was surprised by those numbers myself and decided to look into it.
 Tower legs take all the up and down forces so I compared the specs:

         25G  1.25" OD     16 guage thick
         45G  1.25" OC     14 guage thick
         55G  1.5" OD       11 guage thick

You can see that the 25G and 45G legs are directly related strength-wise
since they are the same OD.  The 55G legs are almost 17% bigger OD with
thicker walled steel.  Increasing the thickness of 25G and 45G legs is pretty
incremental until you increase the OD as in the 55G.  Interesting exercise.

<I need to get that Rohn catalog - great stuff in there - lost mine years ago
- but zeoxed <pages I need from supplier when I installed my 25G - yep -- 25G
when I knew it should <have been 45!!!  

  Get the Rohn catalog from your Rohn dealer or direct from Rohn
(309-697-4400); there are 2 versions, Consumer Products and Commercial
Products - the consumer one has BX and the commercial one doesn't.  They're
$10.00 with a $10.00 rebate.

<I saved some bucks but its just a matter of time that I will pay the
price--- My  25G is <70ft high - mounted in 1 yd concrete, house braket at
12ft, and three sets of guys with <tork bars and equalization plates at
anchors--- 3/16" Rohn with insulators on the two <lower set of guys and 3/16
Philly Stran on top -- whats on this??
<I hate to tell you!!!  get ready for this ----A HS 20ft mast with a
cushcraft 10M 4 elm <beam on top - 10ft down a Force 12 15M 4 elm beam driven
by a Yaesu G1000SDX <and about 10ft below all of that just below the rotor
plate a Tic-Ring with a Force 12 <20M 4 elm yagi on a 30ft boom -- I chose
the force 12 antennas due to their <comparativly less wind loading -----  Oh
well --- It all sayed up in the close call <Hurricanes this summer -- 65MPH
winds--- I think the beams would have blown away <at 80 or above---

   Well, yes your tower is overloaded - Rohn spec says 8.0 sq ft. at 110 MPH
(9.8 @ 90 MPH.)  But they only call for 2 sets of guys of  3/16" EHS at that
wind speed so you have ample guying!  I think your QTH is in Jackson County,
it is a 100 MPH TIA-222-E wind zone; but you already knew that.  Like I said,
when you speed, you don't always get a speeding ticket. Keep your homeowner's
insurance paid up (check into a special rider for your tower system) and have
fun in the meantime!

Subject: Mac Contest Program
Message-ID: <311d5232.k1vr at>

I've just received a letter from Radhames, HI3AB, whom I met
in Dayton a while back.  He is looking for a logging program
for his Mac.  As I am not a Mac user, I've ignored any
discussion on this topic which may have occurred in the
past, and I have nothing to write back to him.  What shall I
tell him?

The absolute BEST contest logging program from my very

It's great!  73, Sandy  WA6BXH/7J1ABV      slay at

I'd get rid of my MAC before midnight when it will turn into
a dumb terminal Sun workstation.


There's only a few programs on the Mac. One is Marathon by
N0IOS. There's a couple of other specialised programs.

I've started working on a contest program for the Mac. I'm
not anywhere near distribution yet. (Indeed, I've barely

There are a couple of MAC logging programs out there but the
best one in my opinion is Marathon by N0IOS. You can reach
Kevin at krueg010 at He has a demo disk of
his program that is full function but limits the number of
QSO's that can be logged. If you're friend has e-mail
capability Kevin could send it to him as an attached file,
that's the way he's been sending all my upgrades. The
program supports all the major contests for cw,ssb and rtty
and also has a generic mode that could be used for

         Smile - no one can tell what you're up to!

One to try is Kevin Krueger's Marathon package.  It pretty
good.  It performs dupe checking, rig control and keying,
report generation, etc for many major contests.  You can
contact Kevin at 'krueg010 at' for full details.
Cost is around $60.00 US.

I've not compared it with publicly available WIntel-based
packages, but the interface is intuitive and 'Mac-like'.
It runs fine on my ancient Mac Plus running System 7.1.

Good luck and 73,  Walt kk6nr

I can highly recommend Marathon (written by Kevin Krueger,
N0IOS; he also writes the Mac software for a major TNC mfr)
as a Macintosh contest logging program. For general logging
Marathon has a generic contest that might be customizable
enough to provide an electronic logbook.

Kevin is a top-notch guy, the Marathon support is superb
(bug-fixes and updates e-mailed out pronto to users, new
disks for major upgrades are usually s&h only, personal
response to individual problems), and in my opinion offers
very good value for the money. Demo disk available.

Kevin can be reached at:

I have no affiliation with Kevin or his product save as a
very satisfied user.

I have a disk with a copy of the program "marathon"
which as far as I know is the original CT-like program for
MACs.  I don't have a MAC, so will gladly send it.  However,
it is only a demo program and will fail after 50 or so QSOs,
but it does have information on how to purchase it embedded
in the software.  I don't know if the seller still exists, I
last used this software about 5 years ago.

Before I switched from a Mac SE to my present Compaq 486, I
used a Mac contest logging program called Marathon.  The
developer is Kevin Krueger, N0IOS.  I think he is on the
Internet at krueg010 at .  Marathon (at least
when I used it) is not in the same class with CT and N6TR (I
haven't used any others), but it has a number of nice
features.  Radhames may want to contact N0IOS (I believe the
Callbook address is current) and get information on the
current version.

Have him contact N0IOS and get a copy of his program
"Marathon" its the best for the mac; its a real mac
contesting pgm, but its not CT; I use it for all the
contests and Kevin (N0IOS) is very responsive. -jim WM1W

A friend forwarded me your DX Reflector inquiry abt Amateur
Radio oriented s/w for Macintosh platforms, specifically
contest logging s/w.  I've used a Mac since their inception
in 1984 but haven't really done a thorough search of just
what Ham Radio s/w is available.

However, I can sure steer you to someone who will know!
Contact John Seney, WD1V.  I've got John addr and email addr
at home but I'm writing this at work.  John is an authority
on Macs and specifically ham s/w for Macs.  If anyone will
know, he will!

The only mac software I am aware of is written by ....

  n0ios;Krueger; Kevin = krueg010 at

It is called Marathon.

Not a mac user and no connection. He was asking me questions
about CQP because he was writting a module for the contest.
I have no idea of the price or availibility.

Hi Fred - the ARRL BBS has a whole section on ham software for the Mac.
Surprisingly, there's quite a bit of it.

If CT/NA/TR and my W9XT Contest Card worked in one of my many Macs, I'd not
have a PC in the house.
