We have received a science grant to visit the North Slope of Alaska, on
the Artic Ocean, at Point Franklin which is a barren penusula located beteeen
Barrow and Wainright.  The purpose is for archeological exploration.  I
will visit about 5 times over a period of three years starting in July
1994.  Need to contact someone on the best way (equipment and procedures) to
set up a briefcase size packet link through----what, a sattelite?  There is
no power where I am going, except batteries and a charging generator that
will be used to power the laptops used for data logging.

Also, need comments on best HF setup.  I have a Kenwood TS-50 and tuner but

I agree.  After some thought on this matter, the above makes sense.
Consider that a J-pole is a 1/2 wave end fed antenna with a 1/4 wave
matching section.  Addition of 1/2 wave sections doesn't do anything
from a driving point impedance (once around the Smith Chart)... So,
at 3x the frequency, the 2m J-pole becomes a 3/2 wave end fed antenna
with a 3/4 wave matching section.  Remove the extra 1/2 wave multiples
and it should exhibit the same impedance.

Alas, there is a problem.  Consider the 3/2 wave radiating portion.  It
is really 3 stacked 1/2 wave units.  Many omni-gain units use stacked
dipoles to squash the pattern to the horizon.  However, what's missing
in the J-pole is the phase reversing elements.  The three dipoles are
stuck end to end -- that is, the middle 1/2 wave section is opposite
in polarity to the end sections.  This results in gross cancellation
of the pattern towards the horizon.  Directly along the antenna (pointing
up), the patterns all add constructively and form the main lobe.  Another
way to look at this is that the antenna begins to approximate a longwire,
which has its main lobe along the axis of the wire.

So, I've come to the conclusion that although it loads up fine and presents
a proper impedance, a 2m J-pole at 440 MHz puts the energy in the wrong place,
unless you are working birds :-)

Now, if you put phasing coils (ala cell phone antennas) between the 1/2
wave sections, the thing could work REAL well.  Been thinking about
this.  Will report if I discover (or rather recreate) anything useful.

Subject: 46 Mhz & 49 Mhz advice wanted
To: [e-mail]

I own a Bearcat/Uniden 210-XW scanner.

I would like to increase the reception in the
46 MHz
and
49
bands.

I was given a mag-mount with removable antenna coil but no antenna.

The coil part which I unscrewed from the mag-mount says K-40 and I think that
this was made for around 466.1500 MHz.

What can I add to the coil to get the reception in the
46 MHz and 49 bands that I want?

The coil has a set screw.

Thanks

Subject: 50 MHz opening in Europe
To: [e-mail]

On the 9th of may the ZD8VHF beacon was heard via multi hop Es and
surprisingly 5T5JC (IL30, Mauretania) was worked by PAoJMH, PA3BFM,
PAoRDY, PAoHIP and PA3FYM. The first stations worked him during a
20 minute opening in SSB, the last station during a 1 minute opening
an hour later in CW. Times: first opening 18.20 - 18.40 UTC, second opening
was only one minute at 19.30 UTC. Signals were in the 55 - 57 range.

Prior to the multihop openings, Spanish stations could be worked with
moderate signals.

We have received a science grant to visit the North Slope of Alaska, on

for archeological exploration with a 3-D ground penetrating imaging
system.  I will visit about 5 times over a period of three years starting
in July 1994.  I need advice on the best way (equipment and procedures) to
set up a briefcase size packet link through a satellite.  There is no power

"We need to do what ever we can to get more folks up there"?

Sounds like good rationale for completely eliminating the code requirement
for HF access.

I'm sure the concept of just making people extend a little *effort* to
get access to those bands never entered their mind. Gosh no, wouldn't
want to make it hard now... that would be bad for sales.

Sounds like a bunch of elitists to me.  This is not within the spirit of
amateur radio at all.
I'd say that such a club should be frowned upon by the amateur community
and not given any undeserved respect.  73

John,
  Does my HF receiver have the required bandwidth for this use when
operating in the FM mode?   At present I have a APT system but, I
don't like the fact that with the NOAA birds, you can'nt frame loop the
images.  Does my HF recv. have to have the same wide bandwith as used
for APT?
  You said that their were other signal to be heard with this
HF/TVRO combination.  When you tune the ASC, whats out there...?
Have you used this HF/TVRO yourself?  I do not have a TVRO system,
however I have been thinking about buying one for some time now.  Any
suggestions on what type of TVRO system I should get?


How the weather in Canada?

And what do you think a duplexer/diplexer does differently?  It operates as
a multi-port isolating device with two (or more) tuned ports all connected
in parallel to a common port where the antenna (typically) is connected.
The electrons do not care whether the circuit L and C constants are lumped
on a PC board or distributed along coaxial (or balanced) line segments.

The only difference between your definitions is the undefined term
"wider-spaced" frequency bands. The land mobile industry makes no
distinction at present between the two terms and they often use the same
hardware interchangeably to provide either function or both simultaneously.

Back in the days when TV was emerging, the term "diplexer" applied to the
filters combining the two Video and Audio transmitters onto a single
transmission line (Dual Insert = DI-plex) and the "duplexer" was used to
let a single radio operate DUPLEX (Tx and Rcv simultaneously) on the same
antenna. Today a general term "antenna combining network" covers both
applications without any artifical restrictions based on vowels or
historical misunderstandings.

I don't remember the issue, but check the annual index to QST for the last
year or two in the "Hints & Kinks" section.  There was a novel circuit using
auto headlamp in series with an AC/DC power supply to charge batteries for
just the purpose you request.  The auto light limited the current draw of the
power supply at full demand, yet kept a constant charge on the batteries.

The article showed use of isolation diodes and MOV's as well; sorry I don't
remember the actual issue.

My direct experience suggests that leakage may be even worse than Ken
describes.  I use a pair of NiMHs in my Toshiba T4500C laptop.  The
performance has been extremely disappointing.  While they do charge
rapidly, they discharge almost as rapidly.  Noticable discharge happens
within hours, and almost complete discharge in days.  Keeping your
second "spare" battery going with a reasonable charge is almost
impossible.  Given standard usage for an HT, I'll stick with NiCads for
the time being thanks.

I don't know about the FT-73, but the Yaesu FT-41 with the appropriate
mods will transmit up to 470 Mhz.  The mod itself is for MARS/CAP and
specified a 420-460 MHz range, but I have tested the unit to 470 MHz on
the analyzer here at work, and it seems to work.  Variations in the VCO
from unit to unit may make it somewhat flaky out at 470 MHz.  Very
small unit, low voltage amplifier.  Not a lot of RF output with the
standard battery pack.

Of course, I don't guarantee that your unit (if you choose to buy one
and mod it) will work to 470 MHz.  Your mileage may vary.  Oh, and you'll
have to get the mods from someone other than me -- I hate to be this
way, but since you have freely admitted that you would be doing something
illegal, I won't help you -- call me tighta**ed, but blame the trial
lawyers.

Yes, type accepted units are hard to program.  That is a requirement
of type acceptance -- make it hard for the user to go somewhere he/she
isn't supposed to go.
