I believe that the FoxDelta is more-or-less a clone of the LVB. I have an
LVB from when AMSAT-NA was selling them pre-built, and it certainly works
fine. I know others with the FoxDelta and it also works fine. If I were
starting over and choosing between the two, since I'm willing to do some
building I'd certainly choose the LVB kit to support AMSAT-UK.

For years Larry Kayser (SK) (VE3QB then VA3LK) tried to get me interested
in satellite operation. It took AO-40 and a demonstration by Clare
Fowler (VE3NPC) at our local Hamfest to get me really excited.

doing SSTV. That P7 monitor was pretty harsh on the eyes. ;)

So many hams complained about that "Donald Duck" sound on HF but the

This argument has been going on forever. There is room for both.
Personally I think I may have been on a FM sat once or twice. To each
their own.

Yes! It's what got me on the sats in the first place. I made one or
two cw contacts on AO-40, my dish was sitting on a kitchen chair in the
driveway in the winter no less, I was waving an Arrow antenna in the living
room and did cw. Yes, that was a real challenge but so fun.
Then AO-40 died as I got my dish up the tower properly. :-(
Challenge is part of the hobby and what makes it exciting!

When I first got my license, 2 meters was the highest freq. typically used,
440 was an experimenters band and anything above that was AT&T Microwave
links for phone and network video. It took a few years but now you can buy
1.2 GHz gear from several sources. The experimenters area becomes common to
all in a few years. I
At my radio beginning, there were no PCs, mobile radios were crystal
controlled mostly, and you bought a keypad to generate telephone tone pairs
to use a repeater auto-patch and wired it in yourself. Things change to
meet the demand and it won't take long to have microwave gear and antennas
easily available. Just takes a demand that a HEO or better satellite in
orbit generates. It's one of the reasons AO-92 has L/v mode.
I welcome the change.

Content-Type: text/plain; charset=UTF-8
Hello EveryoneI recently joined Amsat because I felt like a bit of a
hypocrite for complaining about things, and not doing my part to change
them.?One thing that does bug me is the HEO satellites having microwave
uplinks and downlinks. I think that will greatly limit the clientele that
will be able to use these.
?I have head many older hams gripe about LEO satellites and reflect back on
how back in the day there would be passes up for hours! Many of them where
using drifty transverters with terrible noise figures, turning antennas with
tv rotators and no preamp! The argument that I have heard to move to
mircowave uplinks and downlinks is lower noise, but if it worked with them
back then, then what's changed??
Something else to consider is that the microwave spectrum is under fire from
commercial interest more and more. Why not consider like a U/L or L/U
transponder? That would bring the envelope a little closer to where the
average ham could operate with out investing in some serious equipment,
while keeping the dream of HEO alive for the large percentage of satellite
operators, and not just a handful???
Forgive me if Im wrong, but I just wanted to put my 2 cents in the pot. If
we all would learn to work together as much as we fuss we would be making
some tracks.?Thanks everyone,?Andrew N4LAZ?

One of my earlier forays into amateur radio policy was to found "No-Code
International" and lobby to get rid of the Morse Code test worldwide. We
appeared at many conferences and I even went to Iceland to lobby their IARU
vote, which was the same as that of the USA even though I had half of the
hams in the whole country in one room where I was speaking.
During this period, I expected to be punched out or spat upon by angry
hams. But I was impressed with the civil behavior of hams. Although there
were complaints to ARRL directors that my table was even admitted to the
Division conference, I think only one person cursed me out. And he very
graciously made up after the decision was made.
Certainly no one ever said it was a "hostile takeover". To treat an
election as that is truly ludicrous.
If you like the descent into mediocrity that AMSAT has been on for a
decade, by all means vote for the incumbents. We will work on the issue
over at ORI, instead of AMSAT, and don't be surprised when we continue to
get the participation and grants that were previously directed toward AMSAT.
But there is an alternative. If you want a way out of AMSAT's decline,
please vote for these candidates:
Bob McGwier N4HY
Howie DeFelice AB2S
Jeff Johns WE4B

> Yes! It's what got me on the sats in the first place.
I'll echo this sentiment.
In my case, building equipment is my primary focus and adds to my
operating enjoyment. My most recent homebrew equipment includes a 3D
printed 70cm-band passive Lindenblad antenna, previously mentioned on
this list, and a complementary LNA built from scratch using a MAX2640
device. The latter has taken 11 years to realize, based on the date I
put on the PCB silkscreen. :-)
The 3D printed antenna spreader is being written up now and will be
submitted to the Journal, with the STL and OpenSCAD source files
available for anyone to use/enhance under a BSD-like license.
I completely understand that some amateurs will focus on the operational
aspects of the hobby and have little to no interest in
designing/building hardware. We need this segment of our demographic,
just as much as we need the builders.
It is my hope that more operators discover the enjoyment of building,
and that we have more VHF/UHF/microwave homebrew hardware operating on
the ground with satellites. It isn't necessary to have the latest
multi-kilo-buck touch-screen one-box-does-everything rig to work the
satellites.
It's also my hope that I find some time to work a few of you, now that I
have a workable antenna setup. ;-)

Thank you. I stand by my statement. Hams have met similar challenges
successfully in the past.

Exactomento Zach. I'm a member of a local m/wave club and costs don't seem
to be a detriment to getting on the air. Lots & lots of cheap commercial
gear is available. A soldering iron & some parts tweaking & you've got a
m/wave station.
