I have actually bought time (a year or two) by re-working/re-soldering the
wire.

The pots are the same as the G5400b AZ and EL - 500 ohm 360 degree.
They are also metric but if a suitable wire wound precision pot is found
there is sufficient material in the gear hub to be drilled out. The Allen
screw is also metric. 1.5mm Allen key required
See URL below for some close ups of the G5400B - similar to the 5500 except
for location of the phasing capacitor and limit switches in the AZ.
http://picasaweb.google.com/ve4yz.alan/RotatorRebuild2009#
If a sealed precision wire wound pot can be found that does not have that
limiting looping wire to the center, I would be interested in a group buy to
have one or 2 spares on hand for the next rebuilt and greasing.
Domenico gave me part numbers last year but when I got a quote they were
hugely expensive but they fit my requirement of total enclosed, wire wound
and precision.
>From a Sept 2008 email from Domenico:
Here are many wire wound linear potentiometers that can be adapted.
http://www.potentiometers.com/select_precision.cfm?session_num=2008091501464

The models belove seems to be the best candidates because they are totally
encapsulated wirewound and 360? continuous rotation.

I threw this out there on the eham satellite forum looking for answers
but I'll try here too.
I'm looking for some fairly simple plans for this antenna. Everything I
find either seems to be intended for WiFi or if it is ham related is
full of mathematical formulas to figure length, diameter, spacing etc.
Math was never my strong suit so I'd prefer to find something with the
actual already computed dimensions clearly stated. Preferably in English
rather than metric measurements. I found an article in the May/June 2008
AMSAT Journal that looked promising but there are no hard numbers, just
the formulas and I don't have a calculator capable of some of the
computations, much less being able to work them out in my head. Been a
long time since I was in school!.. hi hi... I have a downconverter I'm
not sure even works and I don't want to spend a huge amount of time and
trouble to be able to test it.
Tnx and 73,

Hi Michael,
I followed instructions from Howard Long, G6LVB, posted here a few
years ago. (If the archives go back far enough, it was in November of
2001). I don't have it electronically, but the instructions went
something like this:
Get a long piece of thick bare copper wire (#10 is what I think I used), and
put a small mark on it every 5 3/4 inches (146mm). Sharpie marker works
well. Wrap it around a
cardboard tube that's about 1 3/4 inches in diameter. The tube from a roll
of paper towels works fine; the dimension is not critical. Space the turns
about 1 1/4 inches (32mm) apart.
Now, here's the magic part: once you get the helix about right, sight down
one edge, and you'll see those 146mm marks you made in the first step.
Twist and stretch the coils so that they all line up, AND at the same time,
keep the turns spaced (center to center) 32mm apart. Take your time. The
diameter of the turns will take care of itself.
For the first 1/4 turn (the matching section), decrease the pitch so that it
gently slopes away from the reflector, which needs to be something around 4
or so inches in diameter. The rest of the mechanical stuff you can pretty
much make up yourself. There are a lot of examples if you browse around the
web a bit.
Helix antennas are pretty forgiving in construction, and really cheap to make.
Greg KO6TH
p.s. If you already have a Wi-Fi antenna, it should work too. Conversely,
I've found that a Helix easily outperforms those "Pringles can" Wi-Fi
antennas that were popular a few years ago, in a Wi-Fi application.

Here is another variation on the same subject. Even if some maths are
present they are not too much out of range for the non maths incline.
What i like is there is no need for a circular reflector as they used a
square sheet of metal for the reflector.
http://helix.remco.tk/
But here is some cheap and very effective antennas at 20$ it is a deal if
you just look at the cost and time spent on building an helix
plus if you want to received something in the other circular polarisation
you will not have this huge attenuation near 60 db's only 3 db's
and don't forget AO-51 2.4GHZ is linear polarized not circular.

Hello Mike
Here are a couple I have used.? Also find attached are a few pictures of
past and some present antennas.? I have followed the same?process and
building methods for L band antennas.? I have used Drake, Transystem, Keps
and SSB downconverters.? The helix is pretty forgiving in measurements.? I
have the book "Antennas" by Kraus and have "tried" to follow the math and
theory.? Sort of fair in that regard.? I find once I have built few and
actually used them, I start to get a feel for them. ? Which downconverter do
you have?? There are several good articles in past AMSAT journals.?
Specifically by Clair-VE3NPC, also K0VTY -Joe, he has forgotten more than
I'LL ever know. ?I have corresponded with?them many times.? I have built
many short helix feeds (5 turns) for off center dishes.? In fact that's what
I used for AO-40 (sobsob).? So, good luck with your efforts.? If I can give
you any hints, suggestions or whatever, just drop me a email.

Hi,
I bought in a hamfest in Quebec, at a very very cheap price, two radio from
Yaesu FT-726R and FT-736R. The FT-736R seems to be very neat. It is already
connected and working with a CAT cable for satellite operation and finally
replaced my 2 FT-817ND. Now I found that I finally have a real full duplex
station, and I have a little more power.
The FT-726R have the 144, 430 & 440 board in it. It is working very well
too, but seems not able to control from CAT.
Is there something I could do with this radio or this one is really too old
to be part of a sat setup ??
Thanks & 73

Hi Bruce,
I printed packets from GO-32 on 23:59 UTC 29 Oct 2009, but haven't listened
for it since then.
Have you been listening to it the last few weeks?
Perhaps it is down again?

I'll come back to my recommendation of the standalone HelixCalc.exe by Jason
Hecker or his web app
Web http://www.wireless.org.au/~jhecker/stuff/Helix.php
Standalone http://www.wireless.org.au/~jhecker/helix/HelixCalc.zip
Why?
Most other web apps allow for 2 inputs - frequency and number of turns. You
then have to do a lot of measuring on a tube of a diameter dictated to you
to wind with the correct pitch and allow for the coil to spring open to a
larger diameter.
The Hecker program allows for multiple inputs and most important for the
DIYer IHMO is the tube diameter you plan to use. PVC pipe, conduit, mailing
tube, dowel or whatever - you use what you have or what you can find at Home
Depot close to you initial calculations. You can also play with diameter, #
of windings etc to see how they effect the theoretical gain.
Print out the form, wrap and tape it on your tube and then wrap the wire
along the printed lines. No calculations and minimal measuring. After
testing your first wire wrap and measuring the amount that the coil springs
open you can enter that new diameter in the calculator. i.e. a 2" O.D. PVC
pipe will not give you a 2" I.D helix - it will be slightly larger as the
coil springs open unless you use standoffs on each loop a la W7LDR helix
construction.
As to the comments on the Wiki... Until it happens... Google! The AMSAT BB
archives are searchable.

Actually:
A comprehensive FAQ with a good search engine linked from the Amsat
webpage would serve well. I know you want me to do it. Sorry, I
don' t have the computer skills. But if such were to exist, when
someone new asks one of the standard questions then all you need is
to refer them to the FAQ (and anyone else reading the mail can also
look for themselves). If the FAQ does not completely cover the
question that a reader has - - then come back and ask on the -bb.
Many good "new" questions come up and can be handled, here, so I do
not think a separate forum list is needed. I already read about 8
lists as it is. Those that often answer certain questions could
submit the item to be included in the FAQ. (i.e. I would offer noise
figure and preamp answers). Others, might offer answers on "fixing
the Yaesu az-el rotor" or software questions, Doppler tracking,
Transponder on the Moon, what happened to AO-40, etc.
my two cents.
