Hiya, Stan --

    Recently I was confronted with the same problem - getting a Ham IV into
25G and was about to resort to the cut-and-hack option when I gave it one
more try.  Guess what?  With a little pushing and prodding, it went right in.
 I am now recommending that people do not compromise their tower integrity by
cutting a piece out of it.  The T2X is another matter.   FYI.

73,   Steve   K7LXC

The 5 element 15M yagi is on the southern slope of the hill but has a 
great view from NW to E.  In other words, the terrain drops quickly in 
front of the antenna in those directions.  West is probably the fastest 
dropoff for this antenna.  Chances are good that I was using this antenna 
if I was beaming west.  It's only 33' (or so) off the ground but is 
always better to Africa than the 6 el at 60'.   And usually better to 
ZL/VK unless the band is very marginal.  The 60' antenna has always been 
better to JA to date.  Also regarding the 15M stack... It's  mostly a 
downhill view for this antenna until you get to pointing a bit south of 
west.  I'de probably be loud on this antenna too.

To date I havn't done anything about insurance, security, etc...  I'm 
over trusting I guess.  The property is VERY VERY remote.  The nearest 
paved road is 1.5 miles from the shack.  The road that leads up to my 
hilltop can only be travelled by four wheel drive if it's been raining.  
Basically... You aren't going to just stumble across this place.  I also 
bought the 2 floor standing Henry amps so the amps wouldn't be easy to 
steal.

I'm going to add a security system this summer I think.  Right now 
getting more antennas in the air is the priority.  My next antenna is 
going to be a 5 element 20M on a 48' boom.  Sticking it on a tower way 
down on the NE slope of the hill at 60'.  I optimized it for F/B and 
SWR across the band.  My hope is that this antenna will help me hear 
Europeans during crowded conditions.  I'll still have the 204BA stack 
available. to Europe.

Check back.  I'm gonna add more pictures later.

In a very narrow sense, I agree, but for the most part I disagree.  Your
previous message (the one that said something like "the 4U1UN emergency
net will be QRV today because we are going to talk to some EL's -- please
don't QRM us") was so incredibly ponderous that I doubt it was really 
worth the bandwidth on CQ-Contest.

By the same reasoning, we should see weekly posts here that say "don't
climb your tower without wearing a safety belt" and "don't eat poison"
because "if just one life is saved, it will be worth the consumed 
bandwidth."  I disagree.

You have gotten the word out about the EL situation with your first few
messages.  At this point, I believe you should move this thread elsewhere
because CQ-Contest is neither the right mailing list nor the right audience
to pursue this thread about the EL situation.

The above is correct (N5RM) and there is a snapshot of the installation (200
ft. rotating) in one of Hy-Gains brochures from 1990 On the back of the
brochure is: Form No. AM 2504-9.

The South Jersey Radio Association (SJRA) will be
active this weekend (1400z April 13 through 2359z
April 14, 1996) operating Special Event station
K2AA/80, in honor of W2EA, who passed away last
year.  A special certificate will be issued for
all QSOs with K2AA/80 this weekend.  See the
Special Events pages of QST, April 1996, for full
details.

As W2EA was active on most amateur frequencies
through UHF, the club is attempting to be have
K2AA/80 active on all amateur frequencies from 1.8
through 432 Mhz, plus 902 and 1296 Mhz at some
time during the weekend.  As a minimum, K2AA/80
will be active in the lower 40 meter General Class
SSB and CW subbands and 2 meters.

As part of its 80th anniversary, the club is
sponsoring four events this year in honor of
deceased members who have made significant impact
on its longevity.

For those with World Wide Web access, the SJRA
homepage, which has additional information on 80th
anniversary activities, can be found at: 
http://waterw.com/~sjra/sjra.html.  
Also, see Worldradio, April 1996, for the SJRA
story.

I hope everyone has an enjoyable weekend.

Greetings Earthlings,

For those wondering when some of the higher HF bands might
again play a predictable role in contests, see the paragraph
below about the spring of 1998. The next peak is also predicted...

* Yup, I'm back from my self-imposed vacation
   (some might say "exile" <hi>) from the contest
   reflector--rested and relaxed. Missed ya-all.

     Are we still having fun??

>From Tad Cook, KT7H
Seattle, WA  April 6, 1996
To all radio amateurs

Solar activity remains very low.  Two days last week, March 30 and
31, had a zero sunspot count, and as this bulletin is being written
a week later the Sun is again spotless.

Over the next few weeks expect the solar flux to remain near 70,
with possible mild geomagnetic disturbances centered around April 7
and April 17.

20 meters is the best daytime band, with the solar activity being
too low to sustain much propagation on 15 meters or higher
frequencies.  40 meters is the best band for worldwide
communication at night, with low solar activity making this the
best time of the solar cycle for 160 meters.

Regarding the end of this solar cycle and progress toward the next
one, the latest projections based upon current conditions and
previous solar cycles suggest that for the next few months we will
be at the sunspot number minimum.   The minimum is centered around
April through June of this year, with sunspot numbers reaching the
Fall 1995 levels in February 1997.

Previous bulletins have mentioned a 10.7 cm solar flux minimum
centered around Spring of 1997, but the latest projection moves
that period up a bit toward the current period.  What it shows is a
minimum based on an average flux of 72 for October 1996 through
February 1997, with the flux also averaging 72 for June 1996.  The
projected flux for the dates in between is 73.

Spring of 1998 should present a radically different picture.  By
then the average flux will be climbing toward 100, and 10, 12 and
15 meters should be alive with activity again.  In April 1999 the
average solar flux is projected at 158, and 192 is the value for
April 2000.  The next cycle is projected to peak around the turn of
the century in August, 2000.

Sunspot Numbers for March 28 through April 3 were 24, 22, 0, 0, 13,
14 and 14, with a mean of 12.4.  10.7 cm flux was 71.9, 70.5, 70.2,
70.1, 68.2, 70.7 and 71.1, with a mean of 70.4.

I vote FOR a Yaesu reflector!  Here's why:
1) many times FT-1000 info is applicable to the '990
2) I also have an FT-890, FL-7000, FT-736, G5400B,
    FT-5100, SP-767 etc etc (even Yaesu clock)
3) no idea where comments for above equipment go?
4) I subscribed to both '990 and '1000, but never see "stuff"
5) I have interest in watching comments about other Yaesu
    equipment in case I ever decide to buy something else
6) I am currently looking for a "mod" for my FT-890 if possible

Thanks for the bandwidth on the CONTEST reflector.  CRAP 
not intended!  73 de Brian
