Newbie here and I am trying to put together a station. I have a question
about preamps. I am making the following assumptions but please correct me
or outline your station feeds if I am incorrect in my assumptions:
Most experienced operators are using moderate to high gain yagi antennas,
circular polarized. I am thinking of purchasing the M2 LEO pack. I am
assuming that most folks are using RF protected preamps to keep from blowing
them up on transmit. It would be easier if one knew that they were always
going to transmit on 2 meters (for instance) and one could place the NON RF
protected preamp on 70 cms. However, since there is a mix of V/U and U/V
birds, it would seem the only way to get preamps up at the antenna where
they belong is to use RF protected preamps ( with weather and RF protection,
significantly more expensive). Is there a role for diplexers here rather
than running expensive RF protected switching? Also, I know from my
listening on my Elk Antenna that change in polarization can make a pretty
significant difference in adequate reception. So, it would also seem that
there is a need with these type of antennas (M2 LEO) to have a polarization
switching (cost for both
antennas almost matches the original cost of the antennas). Do most
operators have these switchable polarization switches. My shack is about 60
feet from the top of the roof, so I will have to deal with those losses in
spite of using good cable. I was thinking of just starting with the
antennas (no preamps, no polarization switching) and see how things go. Any
thoughts or advice would be much appreciated.

Hey Fred,
Hard to say what "most" means, but "Mast Mounted RF Switched Preamps" do
show up at a lot of stations. To your point, one might only purchase a 2
meter version, as so many birds are mode UV. I happen to use one on each
antenna (FO-29 being a big driver for that). In the US, Both SSB
Engineering as well as Advanced Receiver Research preamps seem to be
popular. Either will hot-switch 100 watts, both can be powered via the
coax (although that is a special order item for ARR). I use the SSB
Engineering SP-200 and SP-70 preamp. They were installed in 1998 and have
been working flawlessly for 18 years now, surviving a bunch of bad New
England weather.
Perhaps some folks use diplexers, but I sure would be concerned about
port-to-port isolation. After all, you are pumping perhaps 50 watts out
(+47 dBm), and expecting to receive a signal that is around -120 dBm.
That's a difference of 167 dB. I don't know of any diplexers that have
that kind of isolation. Without adequate isolation you are going to
experience RF blocking on your downlink.
As for polarity switches, keep in mind that most satellites use linear
antennas, so simply using a circular polarized antenna will help minimize
deep fades most of the time. But I also know from personal experience that
sometimes switching from RHCP to LHCP can make a world of difference.
In round figures each step you take is about the same cost: CP Yagi, Mast
Mounted Preamp, Polarization switch. Roughly $1200 for all three steps.
Of course then you need to multiply that price by two (70cm and 2m sets),
and toss in another $1500 for a Az/El rotor and controller, and maybe
another $1000 in coax and control cables. So $5000 for a full system at
new prices. Eek!
Your plan for starting with just the antennas will far exceed your
expectations compared to the Elk. As long as you don't mind pulling
everything down off the tower, putting those improvements in later will be
just fine. Some people will skip the elevation rotor and simply mount the
beams at a fixed elevation of 30 degrees

Hi, Fred
I'm using an M2 2M7 2 meter beam, and an M2 420-450-11 70cm beam, with
an SSB Electronic preamp on each. Prior to dedicating these antennas to
satellite work, they were my "weak signal" terrestrial antennas. I have
them mounted on the cross boom at 45* to the boom so that they're 90* to
each other. I have a"reverse connected" diplexer ahead of the preamp on
the 70cm antenna, and I use a 2 meter band-pass filter at the 2 meter
output of the rig. These things have eliminated the 70cm desense I used
to have when transmitting on 2 meters.
I ran separate DC power leads to the preamps after I blew out the preamp
power switching transistor in my FT-847 by not checking to see if my 2
meter bandpass filter was DC grounded!
The antennas are linear polarized, and work extremely well, although I
do occasionally notice a some fade on certain satellites. It's nothing
that really bothers me, and it saved me a ton of $$ compared to having
switchable CP antennas. Switchable polarization is "nice" to have, but
IMO, unless you have some compelling reason that requires 100% copy,
it's not worth the significant cost premium.
I'm have a "used" Yeasu G-5400B Az/El rotator set I got from a friend
who bought it new, and then never used it. I built a Fox Delta kit
that's a clone of the LVB Tracker, so by using SatPC32, I have full
rotator control and Doppler correction.
I use Davis RF "Bury Flex" cable, although there are other very good
"RG-8 sized" cables available. The DX-400 cable from DX Engineering is
another good quality cable I've used at VHF/UHF with good results.
By all means, start with the antennas, and add things as your budget allows.

In several attempts I have yet to hear myself on the AO-85 downlink.
finally, after playing with SatPC32 this evening I realized it tells me
pretty well exactly where I should be. I ran through an upcoming pass
to see what it tells me and the result is tabulated in the following
table. First column is time (UTC), second column is the fine freq to 4
decimals and the third column are frequencies I can actually enter in my
TH-D72 with its 5 kHz frequency step. 435.170 at AOS confirms what many
ops have told me in the last few days. What I forgot was how fast the
frequency changes as AO-85 passes through its maximum elevation; the
middle 3 minutes will be busy!
Anyway, I was pleased to "discover" this and hope the information will
give me what I need to finally make a QSO or two. Now I just hope I
don't get rained out!

Hi Bob,
A single data point, partial answer to your question... Of course it
depends on where you are in the sunspot cycle, and I didn't work mode K
very often (preferred Mode A with RS-10), but I don't recall many (any?)
times when I should have heard the bird and didn't. Lots of times that
I heard conversations on the 10m downlink of folks who were working
simplex in the uplink passband and didn't know it. But as you note, we
often dismiss and forget missing things due to bad propagation, since
that's the norm on HF.

Saturday July 16th is this year?s date for ?Moon Day? at the Frontiers of
Flight Museum at Love Field in Dallas, Texas.? See
http://www.flightmuseum.com/moon-day-2016/ for more information.? Last year
saw over 1500 people attend this, the largest space themed STEM event in
Texas.? Moon Day 2016?s highlight will be a scheduled telebridge ARISS
contact during the later part of the morning.? AMSAT volunteers will be on
hand along with the Dallas Amateur Radio club to ?show off some fun aspects
of our hobby.? Girl Scouts can work toward a STEM patch by visiting many of
the exhibitors and filling out a worksheet on each.? AMSAT?s setup is part
of that STEM project again this year.? We will have the Fox 1 Cubesat model
on hand to help show the many young visitors the exciting world of small
satellites that they can hold in their hand and communicate through.?
Hopefully we can get some good satellite contacts and HF contacts throughout
the day with our 1X1 special event callsign, K5M.
Volunteers are needed to help man the display tables inside the museum and
also a satellite/HF demonstration area outside, (Shade will be provided).?
Please contact Tom Schuessler, N5HYP for more information on how you can
help with this wonderful opportunity to promote Amateur Radio and what we do
via AMSAT and ARISS to the general public.

I used to love those RS birds! "Easy-Sats" was an understatement. I think
RS-15 is still up there but only the beacon is active. My favorites were
RS-12/13 which I think were on the same rocket. I don't know how many
grids/cards I got on CW and SSB with those two. If I remember right there
was Mode K which was 2 Up and 10 Down and Mode T which was 15 Up and 2 Down.
I could hit those using 10 watts and a J-Pole on 2M and a dipole for 10M. I
believe that 12/13 was somewhere around 250 miles up and RS-15 was around
1200 miles but I might be mistaken about RS-15.
I did find these:

Thanks! Ill research it. The over the horizon DX aspect is what everyone
remembers.
And that is what I want to study. My theory is that with the variability of
the ionosphere, that just as much as there is enhanced beyond-the-horizon
relay some times, there is also times of no-path because the ionosphere at
low elevations is bending the path away from the bird.
My theory is that hams like DX and remember the GOOD DX, but then
conveniently forget all the times when the link was dead. So I think what
I hear from "the good ole days" has to be taken with a grain of salt since
the dead band days are not as memorable as that rare double bounce hop to
timbuktoo.
So far, no one has described how often they could not even hear the bird or
get into it even though it was in range. I think that is the data that is
missing?
