Hi gang,

Leaving in the morning for my next trip.  Here is my schedule:
  31 August to 3 Sept. - Asuncion, Paraguay - ZP5/WJ2O
  4 Sept. to 11 Sept. - Easter Island with group - XR0Y
  12 Sept. to 14 Sept. - Santiago, Chile - CE/WJ2O
  15 Sept. to 18 Sept. - Buenos Aires, Argentina - LU/WJ2O

I know there is no contest going on but have pity and work me anyway.  When
my rate goes below 75/hour I start falling asleep.  

73 es CUL, Dave, WJ2O

I, too, am a regular SOA entrant and I think that an Amateur Radio contest
should be limited to using only Amateur Radio links during the contest, for
spotting or other contest purposes during the contest, including talking to
your buddy and alerting him (or him alerting you) to DX spots.  Use of these
Amateur Radio links would, of course, be a determining factor in the users'
class of entry.

The whole idea is for you to control the lightning discharge path to ground.
If you don't, the lightning will take its own path to ground and therefore
it (the lightning) will be in control!  That'll mean burned-out electronics
gear and possibly worse (a QTH ??).

Electrical grounds are primarily personnel and electrical fire safety
related and are installed to minimize the local resistance to ground from AC

Lightning grounds conduct static and lightning-induced voltages away from
sensitive equipment (including antennas, rotors, indoor equipment and QTHs)
and towards earth ground where they will be dissipated to a non-harmful level.

Each type of ground system is compatable with the other.  Each serves a
specific, yet different, purpose.

If you're going to have an outdoor antenna, you'd better be prepared to
suffer the consequences if you don't install an adequate lightning
protection system.  There is no excuse for not installing a cost effective
lightning protection system.

Think of it as an insurance policy.  If you've got $3000 in CONTEST
equipment, shouldn't you provide a couple hundred bucks (onetime charge,
amortize over 10-20 years) to protect it from total loss?

I'll add AGAIN that everyone should read 'The "Grounds" for Lightning & EMP
Protection' by PolyPhaser Corporation.  Many of the comments stated on this
reflector on this subject have not been thoroughly researched and are
ill-conceived.  The PolyPhaser literature has logical, engineering-based,
emperically-derived data and discussion, which requires some thought, but
which is relatively easily understood.  <No, I am not in any way affilliated
with PolyPhaser; I happen to agree with their approach to professional
lightning protection>.  Everyone should also subscribe to their free
publication, "Stricking News".

Comments/questions are welcome.

I have just sucessfully used CT under WindowsNT 3.51. The CW tone 
(SOUND) sounds a bit and the LPT port is not keying. But it works.
Anyone know how to make this work?

Not to slight any of the environmentalists, but this stuff has really 
gotten out of hand. Wonder if the community in which Steve lives has the 
same environmental impact considerations for new homes being built. I 
think I'm going to have to remove the large picture window in our living 
room. Three weeks ago as I was daydreaming about how the trees in the 
front yard would support a fixed wire beam on 40, a hummingbird smacked 
into the window. He dropped to the flower bed below. A bit dazed he (or 
she - gotta be politically correct also) flew off into a tree and 
appeared to recover. Hope none of you tell Spotsylvania County Va of this 
encounter, or I may have to take my house down. It's in the path of 
migrating hummingbirds. Hope I didn't need an environmental impact study 
prior to planting the flowering pear trees in the yard. Birds might fly 
into them ya know. 

My humble opinion is that the city isn't as concerned with the large 
number of birds that will killed by this installation as they are in 
finding any possible way of preventing it from being errected. 

Uh, has anyone conducted a study of the effects of RF on birds migration 
patterns during the fall contest season. 

Oh, I wanted an excuse to tell everyone of a wonderful sight that can be 
seen from I-94 just south of Eau Claire WI, and I now have it. I have 
often times marveled at the ability of the W0AIH gang to be able to the 
east coast on ten meters via some form of scatter, seemingly at any time. 
Well, as I drove through the area mentioned last week, I could see how 
Paul & co. do it. I'm not sure, but I think they may have more tower than 
W3LPL does! Beautiful stacks. If you're driving through the area, it's 
hard to miss. Looks like a military installation! Hey Paul are you 
finding any dead birds at the base of your towers?

Good luck Steve. Tell your city council to get a life. (Maybe they could 
get into contesting - it's a lot more exciting than bird watching).

I've been talking with Randy now for months. He's been one of my beta 
testers, in fact. The fact is that the elevation-angle data from the ARRL 
Antenna Book (and which are used in YTAD) are statistics. They are valid for 
the entire 11-year solar cycle, all months, all days, all hours. That 
doesn't mean that at any one particular point in the solar cycle they are 
totally representative. I have tried to stress that point repeatedly with 
everyone! Others have asked for specific data for low levels of solar 
activity using IONCAP. (Someday, when I get time...)

In Randy's case, he told me recently at a YCCC meeting that he has never 
felt the 20-m stack at 100/50 feet has much of any advantage over either 
antenna by itself, and YTAD confirms that observation. Further, since he put 
up the station, the sunspots have been steadily declining (hopefully 
bottoming out and rising again, soon!). At these levels of sunspots, the 
lower elevation angles are generally favored, and that is where the K5ZD 
station excells. It's when the sunspots go high again that Randy's station 
will begin to suffer because the terrain is so steep. He can remedy that to 
some extent by lowering the antennas (or putting up more antennas, lower) or 
interestingly enough by going HIGHER for 20 meters. I find that raising the 
top antenna from 100' to 130' while keeping the lower one at 50' will make a 
very significant difference.

So, in short, we know that Randy's station plays, and from his observations 
we know that certain combinations of antennas work better than others. We 
also know that it's the operator that makes the most difference, given a 
certain minimum level of station, of course! In other words, if Randy were 
to operate my station and I his, he would no doubt still wax me -- he's a 
super op!

I've encouraged Randy also to take data from his topo chart for other 
azimuths than 45 degrees to check out YTAD. I know he's been on a business 
trip recently, and I don't know if he's had the time to do this.

I agree, but now face a bit of a conundrum.  The "Grounds" book speaks
approvingly of DC-grounded antenna elements, and particularly driven ones,
from the lightning protection standpoint.  Others, perhaps for antenna
performance reasons, advocate insulating yagi elements from the boom.  My
new Force-12 C-3 CONTEST antenna has all-insulated elements and is designed
for either a coax-coil choke or a bead balun ... hence no DC path to ground.

Any suggestions, clarifications, or other head-straightening gratefully
