CRAP
This is a free society and this is an un-"policed" medium so I am saying
crap.
Got your attention?
I had a broken modem this past week and went without getting my e-mail for 9
days, now I have a nice new modem, and an in-box full of crap. There were 487
messages, predominantly from cq-contest, that took 36 minutes and 24 seconds
to download with the shiny new14.4 modem.
I just spent the last 3 hours trashing messages about QRO/3rd Party
Licensing/and a lot of stuff that habitually comes to the surface. Ya know,
after being without the contest reflector for a week or so - I lived just
fine and now looking at what I could have spent the past week reading on a
daily basis...a lot of it was pure crap.
I know, "just signoff" - NO WAY!
No, I won't lighten up. I am sorry to see the content of the Contest
Reflector continually fading...I feel like it is becoming more like a hangout
for codeless techs, than for savvy hams who like exchanging ideas on
contesting...the cerebral discussions of whether it is better to seperate
different monobanders from a stack on a tower have been replaced with crap.
Several years ago when I was building a station this place was like a
technical library of operating and station design ideas. Don't blame low
sunspot numbers, I know a lot of you are here and not on the air because
conditions stink!
C'mon guys...raise your standards back up, I know I am not the only one
hitting the delete key incessantly (DTR-dude) the trash can in my Macintosh
is full of CRAP!
If we are serious about getting more hams interested in contesting, lets show
them something that challenges their minds - relate exciting experiences made
possible by excercising our minds to build better stations. Share a little
knowledge about a propagation phenomenon that only a contester would know how
to exploit to increase his score. This is interesting stuff, stuff that gets
people interested in contesting.
Do you honestly think that once a month someones stating that there are
stations who run power/soup/gas and a whole cacophone of "ya, me too, I know
guys run power" is setting the hook for the next genenration of contesters???
WANTED: More discussions of propagation phenomenon observed in the last
contest ala K3ZO's posting....NOT WANTED rantings and ravings about of all
things, United Parcel Service, AGAIN!!!
Is there someplace the real contesters are hanging out these days...it used
to be CQ-Contest....but the postings I used to enjoy have dried up, a hole
bunch of cutesy crap ala some chat room from America On-Line has moved in!!!
More talk about the Loos-Gauge....less CRAP from loosers.*

(*Before you get all hot, I enjoy and encourage contest related postings from
all levels of contesters, and do my part to help answer newcomers questions
here, as many will atest...you see I do not mean loosers of competitive
amateur radio events, I mean loosers as in LIFE!)
I gotta dump the trash.....see ya

I am not challenging your opinion about what is filling your inbox. But
there are some pragmatic, immediate sources of relief, other than
trying to change human nature.
1. Sorry you bought a 14.4 modem. A 28.8 would have saved you half the
download time. ISDN even more. Yes, they cost more. Life is tough.
2. I have used mailer software of two kinds
A. This type requires you to download EVERYTHING. This seems to be
what you have. I think Eudora does that.
B. This type just downloads headers. You then download only what
you want to read. This should save a lot of time. My NetCruiser
software does that, which is one of the few reasons I tolerate it.
So, with faster, selective downloads, you spend a lot less time wading
through the CRAP. That does not solve the problem, but does make it
easier to deal with.
One final question. Is this message part of the CRAP,in your eyes? :>)

Hello!
I have five clocks on my station wall to make it easier to realize what
time it is in various parts of the world during contest. My clocks show
the following times: Los Angeles, New York, UTC, Local time and Tokyo.
So, I'm interested if you have day light saving time in LA, NY or Tokyo.
Here in Finland we have day light saving time from the last weekend of
March to the last weekend of September.

Subject: Amplifiers, Contest-Free, and CRAP (long)!
Message-ID: <01BB25FF.9CB1B240@ip053.phx.primenet.com>
The genteleman's CRAP comments not withstanding, I would
just like to say that I heard the "contest-free zone" idea first
being pushed by a local CAC member at a DX club. I thought
(at THAT time) that, perhaps, something like this could solve
many problems in these sun spot challenged times. My reasoning
was faulty! Here's why:
1) Many of the SSTV crowd are cognitively challenged (nit wits).
I hear the same hillbillies on 14.233 all of the time complaining
about everything from their food stamps to contesters.
2) As Jeff (so aptly) stated 10, 18, and 24 MHz are totally contest
(and operating event aka field day) free. I went to 17m during the
last WPX SSB contest since I'm not much for HF SSB contests,
(especially while looking for an amp) preferring RTTY, CW, and VHF
SSB/CW, and I had a great deal of fun and avoided the overcrowded
20m band.
I hope the distinguished gentleman does not consider this message
CRAP, although I could arguably agree. There may be some band
coordination issues that deserve attention (look at the CW/digital section
of 40m), but a contest free SSB zone on 20m is pointless IMHO!
I think it is mostly the casual SSB and SSTV operators who cause
problems. From my recent observations, state-side as well world-wide
communications are well supported on 17m AT THIS TIME.
I hope the distinguished gentleman does NOT consider my amplifier
thread CRAP. I learned a lot! I relied on this group for good, reliable
information in setting up my station (I'll always be a beginner). I consider
the mostly private technical discussions, operating experiences, and
anecdotes I received INVALUABLE. RIGHT ON TARGET!
We probably didn't need another ME TOO message to Jeff's comments,
but let me thank ALL those who responded to my amplifier queries! I
will summarize my comments to date very soon for all those who have
asked!
Pardon my long windedness! 73 de Brian

Contesters, Dxers and Remaining Other Lesser life Forms,
Has anyone come up with an easier way to grease their crank-up
towers other than tipping them over and smearing each articulating tower
leg with grease? Is there a spray on type of lubricant that could be used
instead? Is an annual smearing of the grease appropriate or should this be
a bi-annual festivity?
I don't need multiple messages telling me that guyed towers don't
need this or suggesting I have neurotic Freudian tendencies caused by
early vigorous toilet training. This is simply a question concerning tower
maintainance posed to a group that would have an answer.

Theoretical peak voltage on sinus driven amplifier is TWICE the power supply
DC voltage (including less than 180 deg. conducting class C configurations).
If the amplifier output circuit is tuned on resonant frequency but lightly
loaded, it will represent high impedanse and therefore current consumption
will be low giving LOW power output. But PSU DC voltage might be higher in
the cases of unregulated power supply and exceed capacitor arcing threshold.
Detuned output circuit gives even less power with a devastating dissipation!
SB-220 DC doubler gives 2.7kV plate voltage while idling in the SSB position.
When properly loaded with 700mA plate current, it drops to 2kV effectively
limiting SB-220 output power long before 3-500Z's capabilities are exausted.
In the CW/TUNE position, just 2kV are generated making life easier for the
"tune" variable capacitor.
S5/K4XU told me once: SB-220 is an excellent example of properly engineered
QRO with optimally selected RF components!
If ones needs * several times * DC supply voltage like in TV horizontal PSU,
sharp and hard pulse driving is required to excite inductor with high dI/dt
ratio and then peak turn-off voltages go sky-high! We expierence that when
fast switching relay coils and therefore add protection diode OR capacitor!
Energy is always preserved otherwise we are talking perpetum mobile...

I am forwarding this for my good friend Jim, KF0H.
After losing two Hygain 2el Discoverers to ice I switched to the
supposedly more robust Mosley S402. Since 1993 this antenna has
failed three times including a broken wire in the loading coil
and the latest problem, a toasted insulator block that allowed
the driven element to short out to the boom. I am currently
testing a Comtek 4SQ Lazy-Vee array and was planning on comparing
it directly to the Mosley but now am having second thoughts about
reinstalling the S402 considering it's poor dependability record.
Has anyone compared the Comtek 4SQ's to a shorty forty yagi at
80-100'? Has anyone come up with a fix or the various S402 problems?
Any comments or information will be greatly appreciated.

Ham radio is a wonderful hobby as it covers such a wide variety of interests.
Electronic media has certainly increased the amount of crap but so did printing
However, I wouldn't add QRO to crap basket as I consider it one of the more
important subjects in keeping our HF contesting enjoyable. If we would stick
to reasonable power and clean signals, good reception would improve even with-
out sun spots. Lighter load on memory keyers would be also appreciated...
It is so nice to be part of global vilage even in the country with highest

PLEASE READ THIS!
-----------------
The solution to this problem is very simple and requires a little work.
We change this reflector to be MODERATED. A message sent to a moderated
reflector first gets sent to a moderator. The moderator then reads the
message and approves it or does nothing in which case it gets trashed.
Anyone can be the moderator. It can (and probably should be) changed by
the list owner. Of course someone will be burdened by this task, but if
we share the responsibility of the task, then I don't think it would be
as bad.
What we will get is intelligent discussions again instead of BS postings
by guys that never operate contests and obviously have nowhere else to
call home.

Lew, I don't have a crank up, so have no actual experience with what I'm

If so, then you might try one. They are designed for extreme duty, etc...

and the onus should be on the operator to "practice practice practice"
until getting it right the first time and knowing it's right becomes
second nature.
A checksum of the whole exchange is a kind of synthetic (and imperfect)
synonym for the exchange and a checksum (or polynomial) for the callsign
portion is just an extreme (silly!) synonym. They're redundant and the
redundancy seems to me to be a problem apart from the practical and
other issues that would prevent everybody from using this scheme.
What could be less meaningful than a fixed "599" except the functional
equivalent of "599 599"? What could be more annoying than a check
value that represents more overhead to explain, compute and exchange than
the information it is checking, while adding nothing except a "crutch
factor"?
(But I agree that "59(9)" has value as a "sync pulse". I think without
"please copy" in SS the scores would have been cut in half or the contest
would have needed to be twice as long to handle the fills <g>)
