I'm looking for antenna software primarily for modeling stacked yagis, and
their performance at various heights. I've seen some neat plots from EZNEC,
and heard good things about NEC-WIN. What should I buy?

I seek NEC enlightenment from you modeling gurus... Tnx

element and lots of boom material...seems like I remember that the factory did
some testing on this...yes????  anyway I need a second 40 m antenna to stack
with my 3 el telrex to get some more gain, etc ....comments please??

Why dont we put up a reflector that can recieve input from dx stn's =
(electronic logs) and recieve input from stn's desiring qsl's. Then the =
node could use a background program running all the time to cross check =
(within some small window in time) for entries that match and e-mail the =
qsl back to the requestor? Sounds like a good task for the ARRL or other =

league in 1976 and recieved a very solicitious response. Now thats =
thinking outta da box!

I think I saw a post recently about a reflector where one could inquire
about qsl routes, does anyone have this info?

Have the results of the 1995 ARRL 160 contest been published yet.  I 
admit this is a loaded question.  I've gone through all of my QST's
and can't find it.  I'm either blind or they have not been published.

Thanks.

Hey, I'm at this wonderful station, and I've been checking into Email and

Ken,

Concrete ships float for the same reason steel ships float, they displace a
volume of water greater in weight than the weight of the material used to
construct them.  Having built and raced concrete canoes in college I have seen
it firsthand.  But, you fill a steel or concrete ship with water, and they
sink like a rock (re: Titanic).  Concrete support foundations will not float,
since they do not displace a volume of water greater in weight than the
foundation concrete itself.

Some seemed to question the concept of concrete floating ... 
the more seasoned among us will recall WWII"s concrete ships, 
and there are many small pleasure craft made from concrete 
sprayed on a wire mesh form.

Isn't it more likely that what happens is that the wet sand above the anchor
does not exert the same resistance to the guy-wire's pull as when dry?  Less
cohesive soil (like saturated sand) would tend to flow around the anchor
block, allowing the guy wire gradually to pull it to the surface.  I know
this could happen in my Rohn-standard application, because the anchor blocks
are not heavy enough by themselves to handle the maximum guy wire pull they
could theoretically sustain.  They rely on the weight of the earth above
them, and its cohesion with the surrounding soil.  Fortunately, mine aren't
in sand, but I had a worried few days this summer when the area around one
guy anchor flooded.

best 4-hour Sunday afternoon score?  Any takers?

I can't speak for other areas but in the NY/NJ/CT area FMers stopped 
participating after the ARRL banned 146.520 from use during contests.


Other frequencies such as 146.49, ,55, .58, 147.51, .54.57 have been 
used for group monitoring in this area and contesting has always been 
considered a nuisance.

Maybe if contesting had been allowed and people stayed on 146.520 
there would be some people slumming over on the righr weekends.

People here do use 146.520 for FM QSO's during Field Day as there is 
no restriction then.

Hi guys, and thanks to those who worked me - GM6X. - 40m SOSB.

Well, its 2215 on Sunday night and well may you ask - why is he
here and not on the rig?

Well things did not go quite according to plan at GM6X.   Our site is on a
hill top
farm in the south west area of Scotland (home of GM4NFC -actually).
I normally borrow a laptop computer for the contest, but this time I left it too
late and had to us my trusty old 386, with CT.   However, the computer
didnt like the linear and fell over every time it was keyed.   Got it sorted -
well almost just before the start of the Contest - but guess what - Murphy beat
us to it.   Dont know what the problem was but propogation on the Friday
night/ Saturday morning was very poor.   Likewise the early morning long path DX
opening didnt happen.    Went to bed hoping for a short path opening to VK/JA -
Yes you guessed it - didnt happen.   We had a blizzard and snow storm on the
Saturday night/Sunday morning, lost the rotator on the 40m beam, lost
the computer several times and finally lost the electricity supply to the
farm about
1300 on the Sunday.

So this year's test was a dead loss.  Less than 1,000 Qs......
Poor condx, very heavy rain/snow static, computer problems, high noise level
and finally no power killed not only the station but the enthusiasm.   Had to
drive home through a blinding blizzard..........

How I wish I was in southern California- where it never rains
