Hi Ron,
I built the helix because they are fairly tolerant of slight differences
in
materials and assembly dimensions. I am by no means a precision builder,
so
this seemed right for me.
I have an ICOM 1271A in the shack, which is supposed to put out about 10
watts. This goes to about 5 feet of RG-214 (I think - it's the 50 ohm
stuff
that looks like RG-8, but has better shielding), to a box outside where
there's supposed to be a lightning arrestor. That's on my list of
things-to-
buy-soon... Right now the arrester is just an N-N barrel connector. That
feeds about 60' of Andrew hardline (LDF4-50A) up to the roof, where there
is
another barrel connector and another about 5' of that RG-214 to go around
the
antenna rotor to the antenna itself.
At 1.2 ghz and 50-odd feet, I expect that hardline is going to be a
requirement. Or you could mount a power amp and pre-amp at the other end
of
the coax, along with power and sequencing logic. The hardline I got was a
trade from another ham who worked, I'm guessing, in the CATV, Telephone,
or
similar industry. I got something like 180 feet of it in trade for a
short
70cm antenna, enough for 3 runs to the roof. There was a bit of a kink in
the
middle, so that run is on a lower band :-). Ask around, you might be able
to
scrounge up something.
Good luck,
Greg KO6TH

Greg:
I havent worked with hardline before. This may be getting mvoed from
time to time. For now, I will have it at home. I would like to move it
to a Field Day location in June. Will hardline tolerate that or should
I look at another type of feed line ?

Hi Ron,
My Az rotor is a ham type (pedigree unknown), but the elevation rotor is a
simple Alliance U-110. I think I paid something like $5.00 for a pair of
them. As you scan see in the pictures, it handles quite a lot, as long as
the
balance is kind of close. If it matters, I chose to put a simple screw
into
the horizontal shaft where the Elevation rotor drives it, so it's not
super
stiff at that joint. Gives the motor a little "give" when starting.

Jesse:
It has worked for me. When AO-51 is in V/S mode, I have to use a
seperate radio for the downlink. In my case, the K5GNA converter is set
for 2 meter IF and that is fed to either a handheld or an ICOM 706MKIIG.
I let my IC-910H perform the uplink duties. That may be overkill but
that is my primary satellite rig when operating at home.

Hi Ron,
Hardline really hates being bent. It's not really a Field Day sort of
material, but then we rarely have 50' towers on field day either. I'd
still
go for Field Day, but leave the hardline at home and use a sort piece of
LMR
or similar coax.

Dear all,
Based on my simplistic experiment of yesterday, May 12th, I would say that
after the first two weeks in space the spin rate / rotation of Delfi C3
has
not changed much (read: reduced). At least, due to the multiple variations
it's difficult for me to observe a significant change already.

Bob, Ron and Greg:
The problem we have at this point is that uplink and downlink
performance has not been specified by the P3E team. So, in my
thinking, one can only go with the AO-40 experience for making
enigneering decisions for your ground station. On SSB I found that
9.5w and 20-dBi (linear pol) was inadequate for AO-40. It looked to
me that I needed a minimum of 15w and more would have been
better. This is power at the antenna terminal not at the radio, so
one has to calculate line loss.
For operating the Leos your uplink needs are probably less and I will
leave it to experienced operators to state what that is.
Fortunately, Times Microwave gives you a wonderful on-line cable-loss
calculator for their entire line of cables:
http://www.timesmicrowave.com/cgi-bin/calculate.pl
or you can download the zipped program to run on your local computer:
http://www.timesmicrowave.com/cable_calculators/
Plugging in LMR-400 x 50-feet at 1268-MHz results in 2.3 dB line loss
or 58.3% power at the antenna.
Using my AO-40 requirement of ERP = 15w x 100 = 1500w: One would
want 25w at the radio end of the 50-foot cable.
Bob has this easily with his KJ6KO 60w amp with over 3-dB spare. BTW
my current 1296 setup uses 150-feet of 7/8 hardline with ~20 feet
LMR-400 to give me 20w at the antenna (I have a KJ6KO amp as
well). For satellite, I will probably mount my 15w 144/1268 Tx
converter at the antenna, thus eliminating expensive hardline. I do
that for my 435-MHz uplink by using a 50w brick at the satellite
tower and using 125-foot of RG-213 to provide an input of 12w from my
FT-847(50w). I have an outside equipment box with 12-v power supply
and room for preamps and coax relays:
http://www.kl7uw.com/sat.htm
Bob, you might be OK with a 16-dBic Helix considering the power you
have. A 4-foot dish is equivalent in gain to a 12-foot long Loop
Yagi (20-dBi) and much harder to mount and aim, so my recommedation
would be using yagis to get the gain (and be easier on your az-el
mount). If I recall the M2 yagi has that. Don't forget that you
gain a 3-dB advantage when using a CP antenna on Mode-L. If you are
going to use the dish for 2.4-GHz reception then dual-band use might
be an advantage.
With Ron's 10w in the shack he will only have about 5.8w at the
antenna, so you may need more gain. For P3E this is most likely; for
AO-51 that might be OK. In any case I would recommend LMR-400, at
minimum, as low-loss cable, or placing a brick amp at the antenna to
boost up your power. Note: Dale-KL7XJ runs 10w on 1268 to a helical
beam on AO-51 so, without knowing his line loss, one might guess that
50-feet LMR-400 + Helix will be adequate on AO-51.

Just near the end of the SEEDS pass i copy another doppler affected CW
signal.
The short CW transmission start with XIV and strings of
numbers. I think it is CAN X but i don't get a lot of details on their web
site.
Signal was quite load to interfere with SEEDS signal?

I am still baffled as to why this is happening... the clock on the AO-27
website agrees with my PC clock, we are both using the same EPOCH.TXT and
TOPR.TXT files, and yet the website is somehow calculating different event
times than my son's program (which, as you said, appears to be calculating
the
correct times).
I just checked now, and at this moment, the website is behind by just over
5
minutes... I should try to get in touch with Mike Wyrick and see if he
can
tweak something over there at ao27.org.
George, KA3HSW

Here is an interesting article I just found that mentions the launch
delays of
Sumbandilasat. If you recall this satellite carries an amateur radio
secondary
payload, and was supposed to have been launched last year.

Hi Luc,
I believe that CANX 2 doesnt have or operate a 70cm beacon.. :(
Only from what I heard from the launch team.
Thanks,
Chris

Unfortunately, I had no success with the AO-51 V/S mode this past week.
Before the next V/S mode operation comes around, I want to double check
performance of my antenna and downconverter. Some of the folks in the UK
had
these items available during AO-40 days but don't think they're available
today,
such as:

(http://www.uk.amsat.org/index.php?option=com_content&task=view&id=252&Item
id=
86)
I've seen Bob's K5GNA 2.4GHz Source
on eBay with the:
_http://cgi.ebay.com/2-4-GHz-SIGNAL-SOURCE-GARDINER-TYPE-LO2398-AMSAT_W0QQi
tem
Z110251114382QQcmdZViewItem_
(http://cgi.ebay.com/2-4-GHz-SIGNAL-SOURCE-GARDINER-TYPE-LO2398-
AMSAT_W0QQitemZ110251114382QQcmdZViewItem)
Are there other small modular type 2.4Ghz Sources out there that I can use
to verify downlink setup?
Thanks,
