Subject: 6 Meters-New op needs advice.
To: [e-mail]

Hi, everybody. After years of HF DXing and contesting, I decided
to expand my horizons and get a 6M rig, to work lots of sporadic-E.
I picked up a used Yaesu 625-RD and got a 3-el beam up at 40 feel
with 9913 feedline.

                         I haven't heard a thing.

     I know that it takers some luck and effort for the MUF to hit
50 MHz right now, but I'm wondering if the band has just been
REALLY DEAD, or if I've blown my installation somehow. Maybe I
have a sick rig. All I know is that I'm in EN50, and I haven`t
heard anything from the southeast at all... a path I was told
to be fairly reliable.

    Am I just being too impatient, or what? There's nothing like
getting a new piece of equipment and not hearing anything. If
you've got any info for a 6M neophyte, I'd be grateful. 73 de

I have the following items in my collection, that I was going to get it
working and use it as CW transmitter, then again I'm thinking about
selling it and buy something that I can plug and play.

So..my question to you all is how much are they worth. They were made by
Bendix Radio for Navy Department with contract dated 20 May, 1940.

I can't think of a better bbs (and packet/internet gateway) than the

to use it as my home bbs on packet even though I live in Portland, Oregon.
The remote access via Internet is great.

Here's some relevant info:

N0ARY/BBS Internet Gateway Operating Instructions
August 7, 1992

LOCAL USERS:
------------
Local users are those that log into the bbs via the bbs's
telephone modem port (408-749-1950) or via one of the 3 tnc
ports (144.93, 223.62, 433.37). Each local user has a bbs
account that is used to customize how the bbs interacts with
the user.

Local users can set their account up so that all incoming mail
addressed to their call will be forwarded via a gateway to internet
and on to other networks (mcimail, compuserve, etc). All the user
needs to do is enter his email address and turn the feature on.

If you are interested in using the N0ARY packet/internet gateway; or if
you simply want to access his bbs remotely via internet, here are the proper

Greetings CWISTS, Boatanchorites, Fellow Hams, et al:

I will be on again at 0400UTC for the continuing saga of the Sacred and
Most Honorable Friendly Society of Brass Pounding Fist Functioning CWISTS.

Last Friday Night, there were only a few folks that showed up, probably
because of the summertime blues and committments elsewhere.  The 80 meter
QRG was quite good, but a bit noisy with the eastern US storms about.
I did not hear anyone on 40 meters (someone scout out a good 40 meter
QRG in the novice band).

There has been a lot of interest on the rec.amateur.radio newsgroups
on sending CW and the general poor quality of many fists these days.
Let us do a little to promote, not only the art of receiving CW
radiotelegraphic communication, but also the art of ...sending... good
CW radiotelegraphic communication.  It is perfectly fine to have an
individualized fist, and it is often easy to tell who is aboard on watch
at the key, just by the first few characters received, but it ...should...
be a point of pride and operating skill to be able to manually send
characters of sufficient integrity as to be readily received by all who
might be in a position to hear same.

So, let us all see who will be on watch this coming friday night
(saturday morn 0400UTC).  Run your treasured boatanchor if you can, or
even that newfangled rice box supreme, or even that fine homebrew QRP rig.

The general information is:

   +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


Let us all work together to continue to advance and promote the friendly
use of CW on the amateur radio bands.

Let us continue to assist and help the newcomers and slowspeeds who
are trying to get their CW going.

Let us to continue to promote the use of whatever gear you have up
and available, be it the newest of sorts or the oldest boatanchor.
Remember, CW generation has not changed since the days of arcs,
Alexanderson alternators, and Pliotrons.

Let us continue to promote the sharing and fellowship of the history
and traditions of amateur radio (this includes all you OTs out there
that have all sorts of goodly tidbits of history to relate to the young
squirts on the block, and it includes all you young squirts on the block
who, even though a bit new at CW and radio are the future of the service
or hobby or profession).

Let us continue to promote the ``elmering'' of all of our new folks
by the old timers aboard, in any way that we can.  We should not be
out to convert the brethren to CW, but should be there to elmer them
and assist them in learning/practicing their skills, if possible.

So, OTs aboard, young squirts in the wings, high-speed afficionados of
the art, and slow-speed ragchewers, join in on the fun.  If your
equipment is old boatanchor, so what.  If your signal is a bit weak or
chirpy, so what.  If your antenna is just a mere piece of wire up into
the trees, so what.  YOU can still join in and participate.
YOU are the folks who will make it what it can be, a goodly learning
time and an enjoyable evening for all.

See You There OM/YL.....

I was told by a very reputable source that the license turnaround time will

license turnaround will average less than 2 weeks.

the area underneath these seats goes away when the seats

The most common would be the Alford slot antenna. That's just a waveguide
or rigid coax with rows of vertical half wave slots cut in it. This will
produce *horizontal* polarization. If a *round* waveguide is used,
and several rows of slots are used (typically 5), then a good semblence
of an omni-directional horizontally polarized signal can be produced.

Another omni with gain is a dish firing straight up into a cone such
that the signal is reflected off the cone in all directions. This is
like a splatter board (periscope) antenna except instead of a flat
plate a point down cone is used instead. This style antenna is good
in that the feed point is on the ground. The support structure for
the cone can distort the omni pattern, however.

As long as the *physical* size of the antennas at both ends are held
constant, line-of-sight path loss at VHF, UHF, and microwave all remain
the same. However, an antenna that's large compared to a wavelength *will*
be directional. The practical limit to "squishing the donut" for an omni
antenna is fairly rapidly reached, so antennas that are directional in
azimuth as well rapidly become the antennas of choice as the frequency
climbs.

On non-line-of-sight paths, microwaves generally experience greater
attenuation than UHF and VHF signals. However, forward scatter works
somewhat better because the common volume becomes smaller. Microwave
also tends to work better via passive reflection from objects. This
can allow good "bounce" shots when the direct path is obstructed.

While repeaters at microwave are possible, it isn't trivial to get
good performance. It's probably best to operate in hub and spoke
fashion instead, with directional antennas at the user locations
making up the majority of the gain while having a modest omni gain
antenna at the hub. To work well, this requires a different protocol
than the CSMA used at VHF because most user stations *won't* be able
to hear each other. A token ring or slotted approach works better by
giving positive control to station access. Glenn Elmore has been
implementing such a system called the Hubmaster.
