Subject: Day.Hamfest remote control for contesting meeting?
To: info-hams@ucsd.edu
anyone interested in discussing remote control for contesting
as an unschedule informal meeting during the dayton hamfest please
contact me (jose aponte - kp4uy). I will be working in the speaker &
forum desk, if not there please leave contact information & interest.
as a reference there was an article on cq july 93 page 68
that talks about the servant station. internet can be a land line
that would carry digitized morse code to be received by master. there has
been efforts by at&t to carry live packatized voice... anyone care to comment
on this? a way of doing it with existing tcp/ip? there are other issues on
how a station on the us can compete with the big guns in remote locations?
at present cq ssb wpx contest states that the xmiter needs to be connected
physically to the antenna, at least that was last years rule. so it is
posible to those rules to operate remotely, right? anyone care to comment?
on rules, interest, ways of doing it?of course you can't move the station
around from location to location depending on conditions... but what are the
rules for someone operating out an airplane, ship? no flames please because
they will not be read or replied to... only constructive comments.. gracias

I just got a high power tube and am wondering what it's characteristics

I may consider selling it, but it will make a great conversation piece in
the event no one does.
For what it's worth: I also have the filament transformer (6V 100A),
blower and socket. It is mounted in it's socket.

The system manager at FCC.GOV said he'd eventually set up a mailing
list for people who don't have FTP and want the digest. Until then,
I'm not getting in the way if someone else wants to FTP the digest
and post it or e-mail it to those who don't have FTP. I've achieved my
goal of getting you to understand the importance of following the FCC's
daily business.
Once the FCC.GOV FTP archive went on line, I took the time I was using
for the digest postings and started the ARRL-policy mailing list.
That's worked out very well so far - many ARRL volunteer staff and paid
employees are on the list so we're arriving at some real understanding
instead of the bluster that goes on in rec.radio.amateur.policy .
I'm also running the mailing lists for the Debian distribution of Linux,
and I'm building a 9600-baud bit-regenerating packet repeater for the
San Francisco Bay area, and I'm being a Newlywed, and I have a job at
Pixar. Did you see the restored version of "Snow White", or the lack
of seams in the cones of "The Coneheads"? I wrote some of that software.
So someone else please distribute the Digests to the people who don't
have FTP!
Thanks

Hello ALL,
I have just purchased and received the new Standard C5718 Dual Bander
Mobile Radio and was wondering if there are any others out there with
one?
I would like to correspond with you and compare notes on any problems
and/or fixes you may have encountered.
I have found one so far....The Cross-Band Repeat feature only seems to
work if I do not set a plus or minus offset for cross-banding into
another repeater. I called Standard and they said that they have a
upgrade chip that they will install at no charge.
Has anyone else had similar or any other type of problems?
Thanks,
Bill, KD4LLQ

My experience with noise blankers has been that they have virtually no
effect on background nois. After all, this IS random noise. What it
does work on in PERIODIC noise, such as a car's ignition system, or the
static coming from a blender plugged into the socket in the next room,
or various kinds of periodic pulse noise.
Scott NF3I
It can be useful, but using in plain, old 80 meter noise can actually
distort your desired signal.

The noise blanker reduces impulse noise. The sort of noise
generated by mopeds, lawn mowers, electric fences etc. This is a nice
feature on a mobile rig. If you live in an RF quiet neighbourhood, you
don't need it.
I have an Omni D with the noise blanker. I use it in rural
Wisconsin. I have played with the noise blanker, but have never needed
it.

Now, I'm just studying at this point, but I thought the standard testing
procedures, if there are any, shows that an applicant attempts to answer
10 questions. If they get less than 7 correct, then the tester looks at
the copy sheet to look for solid copy. Maybe we are in the same boat with
my guess that back-filling should go on before the test sheet is given.

That's what the military and commercial operators discovered too. Copying
with a typewriter is much faster than copying by hand. That's why they
*teach* the Code that way, and why intercept operators always copy with
a keyboard. Note that what they want is an accurate and legible copy of
what was sent. Since most intercepted traffic is encoded, and most commercial
traffic heavily abbreviated and filled with "commercial codes", flawless
copy is mandatory or all meaning could be lost. That's what the FCC wants
on the test too, though the current amateur test doesn't require zero errors,
just one minute out of five perfect copy, or the answers to the multiple choice
questions as the case may be. That level of performance would wash you out at
military or commercial levels of required accuracy.
Copying in the head isn't real copy, but it's what some hams do on the
air. That's because their communications content isn't important enough
to require perfect or permanent copy, and because they can "fill in the
blanks" from plain English context and from the standard amateur QSO format.
That wouldn't do if artillery coordinates were being sent.

Actually, I think you'll find that your Sound Blaster code wouldn't
do a very good copying job on normal, noisy, interference filled, HF
channels. It's possible to exceed human Morse copying ability with DSP
and/or massive processing, but it's neither simple nor cheap to do it
in real time now. That's because Morse is an irregular code with
non-uniform element lengths, spacings, and character lengths. It's
also normally sent by incoherent on/off keying. Machines can easily
exceed trained humans in flawlessly copying signals buried in noise
and interference when the encoding is uniform and coherent, but Morse
is not a good code in those respects. It was designed, rather haphazardly,
in an era before a good understanding of information theory existed.
And it was designed for use on essentially noiseless and interference
free wire lines. It's use over radio is more of a historical accident
than an intelligent choice.

I seem to remember that back when I took my 13 wpm code test in the FCC
offices in NYC, the receiving portion of the test required only one solid
minute out of five or so. I don't remember whether the text was plain or
code groups. Of course, there was also a sending test, using a straight key.
It was 1960 or 1961, I was in high school, and intimidated by all the glory
and grandeur of the Federal Gummint, so my memory may not be very accurate.
The point is that, at least at that time, the FCC didn't require 100% accuracy
for the entire test session, just a burst.
73,
Bill.
