Dishes like that or the larger "BUD" (Big Ugly Dishes) that folks USED to use
for TVRO can often be found FREE (for the removal) in many neighborhoods.
I have two "standard sized" BUD's, a 12'+ fiberglass monster (not likely to go
up), and a "mini" ex-dish network one, and actuators for the 3 biggest ones...
net cost for ALL: $50, and that was labor for a helper to take down the
biggest one.
Separately I actually BOUGHT an N3IYR 3' dish a few years back, but it wasn't
terribly expensive. It came with a helix feed.
Granted, it's not always something everyone has laying around but they CAN be
had cheap or free for a little effort. If it were golf, people wouldn't just
find a driver or putter in their yard, growing like a mushroom, either. :-)
The hobby of amateur radio is worth taking some time and effort to invest in.
Kind regards

AMEN AGAIN !
My first attempts at Oscar 10 were with:
Transmitter: Heathkit HW-24 FM rig, keying on CW (10 watts), 7 element
vertical polarized yagi, no elevation.
Receiver: Yaesu FT-221R no preamp, 12 element yagi horizontal polarized,
no elevation.
Many contacts made. Subsequent improvements made things better for sure.

Ahh, I think I'm gonna have to trump you with my Bike Mobile setup (not
satellite related, but it did make September, 08 in the CQ calendar).

Also, my old satellite setup worked pretty well. I had to do a little
photoshopping so you can see the antenna very well.

Joe,
Welcome back to satellites. I got started by
helping set up the AO-6 West Coast Command Station.
But one thing you say has me puzzled: CW on a
LEO? They only do FM. Exception is AO-7 which
is a MEO and the Indian sat which has a linear
transponder which will pass CW/SSB. Or you
planning to send MCW by tone modulating the FM signal?

Tony,
It was probably mentioned in some of the Amsat Journals, but it was
determined that the original "C-C Rider" project (5.6 GHz up & down)
was not feasible to build. Thus discussion ensued that ended up with
using 3.5 GHz as a downlink. It is much easier to build full duplex
filters for the wider freq. separation.
Although 3.4 Ghz is not a world-wide ham allocation, anyone can
receive there. The Flyer probably needs an update. I cannot answer
on that. All Amsat is done by volunteer work. I suspect some tasks
are begging some help!
I would like a little more info on Eagle and P4, as well. Likewise
news from Amsat-DL on P3E would be nice.
I think most of us appreciate that a lot of work goes into getting
these new Heo's into orbit. Most of use are armchair observers!

Hi Andy,
You have nothing to apologize for. You posting showed more balance
and maturity than the ranting of the 3 or 4 "gentlemen" that appear on
the list from time to time.

Hi folks,
In the past, the candidates running for the AMSAT Board of Directors positions
have used this forum to provide the membership with some thoughts and ideas
about their intentions if elected. I would very much appreciate if that could
happen again. Also, in light of the current discussion on LEO?s and HEO?s, it
would be very helpful to see where the candidates are standing.
Thanks,
73, Stefan VE4NSA

I beat you 2 BUD 7.5 and 10 feets an oval 5 feet in my backyard plus about 10
around the town (i count fast here) ready to go down for the
first taker and one huge aluminium 16 feet (My guess) just on a pole aside of
an arena here..oups 2 more on a finance retaken building they
sold all the contents even the old receivers in an auction but no one bid on
the 2 BUB.
P.S it takes 2 days with one of my friend to take down 2 10 foot to the ground
no crane or boom truck just industrial chain block and loose
nuts oil torch bolt cutting grinder and a bit of luck in the decent phase...

I have a kind of minimal satellite antenna setup: a 16 element and a 14
element, both horizontally polarized, with no elevation. I notice that on
some passes I can barely hear the satellites, or not at all, and other times
they come through strong.
Would upgrading to a real satellite antenna system: circular polarization
with elevation remove these variances in signal strength? With such a
setup, would I have perfect copy on every sat pass, or does is the
differences in signal from pass to pass something everyone lives with?
