I am pleased that AMSAT-NA is going to move forward with a LEO
CubeSat, single channel, analog FM transponder. If successful, it
will be immensely popular worldwide. My hope is that it will help
usher in a new, improved series of satellites with more advanced
payloads. There is great potential in the ranks of AMSAT-NA and
groups worldwide to achieve lofty goals. Look at what AMSAT-UK and
others have already done in the CubeSat platform. The digital mode
capabilities discussed here on the AMSAT-BB are just the tip of the
iceberg to where technology can take us.
It's very easy to be a pessimist or a cynic. Very little risk is
involved. It doesn't take any cojones to sit in a comfy chair and
email snarky comments. If you are optimistic about a project and it
fails, your peers may see your actions as a fool. Even worse, people
may withdraw their financial support for future missions. Even after
great success, the optimist may receive very little praise, especially
in this field of voluntary amateur radio service.
AMSAT-NA is boldly entering the CubeSat world with the planned
satellite series FOX-1. If you haven't noticed, there have been
full-page advertisements soliciting volunteers in the AMSAT Journal.
There is plenty of opportunity to serve and influence the direction of
AMSAT-NA.
If we all threaten to leave and stop paying our dues when things don't
go our way, what will we ever accomplish?
Please take a simple step to support amateur radio in space. Donate
to the FOX-1C launch effort. http://www.amsat.org/?p=2957

I will be operating portable from the old Marconi radio site on Cape Cod in
grid FN51. I will work SO-50 passes on 7/23/2014 at ~17:32 UTC and on
7/24/2014 at ~17:58 UTC. I will not have my usual portable system, but will
operate with a HT and a whip antenna. This may make contacts more difficult,
but I hope to catch many of you from FN51.

Brad,
I have looked at them for mobile operation, but I'm not certain that
they would have enough gain to work well inside my attic. I'm going to
try the Diamond 11 element Yagi to start with. Low cost and I can put it
to good service for portable 432 operations if it turns out not to work
well in this application.
What is your experience with using the Myers indoors?

I've been meaning to ask...
It's been a while now, since Amazon introduced the Smile program. Is
there anyone who knows if it is paying dividends of any sort? Is it rude
of me to ask? I'd like to think that anyone who supports amateur
satellites would have signed up, but who knows? Maybe I'm the only one
that did! (Actually, I know a couple others signed up at the same time I
did, but I can't remember who.) Anyway, just wondered if the whole
thing was a storm in a teapot, or if the ham satellite programme is
receiving any real benefit.

Dear radio amateurs,
Today during 04:30 UTC pass over Lithuania we have turned on LO-78 FM
transponder again. Transponder operation might be interrupted during
command sequences tomorrow morning. Wish You all good QSOs!
p.s. As it might be interesting how the signal changes during the decay we
encourage you to share your feedback with us.

Sorry about that, I was primarily thinking of AMSAT-NA members when I
said that. Forget the DirecTV receiver itself and consider their
offset-fed Ku-band dishes and 0.7 dB NF LNBs that are readily available
on the surplus market. Since DirecTV isn't available in Barbados, paint
the dish with the logo of whatever DBS provider you like. Nobody will
know the difference.

And here I am with you 100%. So many hams seem to automatically assume,
for no good reason, that getting on any new digital mode must
necessarily require exotic, expensive and hard to find components and a
PhD to use. But the required hardware is now very common, and nearly all
of the "complexity" that defines any particular digital communication
system these days is implemented almost entirely in software that costs
nothing to copy and distribute once written.
The hardware to run said software already exists in virtually every ham
shack. Even a low-end general purpose PC is a very capable DSP engine,
and this has been true for almost 20 years since Intel introduced MMX,
their first set of DSP instructions for the x86 CPU. Since then there
has been SSE, SSE2, SSE3, SSSE3, SSE4 and now AVX and AVX2, Advanced
Vector Extensions 2.
Here's an example of how far consumer DSP has come just in the time I've
been involved with AMSAT. I wrote the demodulation and decoding software
now used by the ISEE-3 Reboot Project. It takes the A/D output of an
Ettus USRP software defined radio, tracks the RF carrier, demodulates
the phase modulation, tracks and demodulates the binary symbols, and
performs error correction to produce raw telemetry frames.
ISEE-3 uses a rate 1/2 constraint length k=24 convolutional error
correction code. When it was launched in 1978, decoding it took highly
specialized, dedicated hardware. Someone here who worked for Linkabit,
the manufacturer of that decoding hardware, can probably jump in with
the exact cost in millions of dollars and the number of 6' equipment
racks it filled.
I am doing all these functions on mThe Viterbi algorithm is traditionally used with much shorter codes
(k=7, first used on the Voyagers, is still common) because its
complexity doubles each time you increase it by one. Had I suggested, in
1978, using it for a k=24 code (taking 131,072 times as much effort as
k=7) NASA would have laughed me out of the room.
The same reaction would still have been justified in 1985 when they
renamed it ICE and sent it out of earth orbit to the first-ever comet
rendezvous, requiring Herculean efforts to overcome the extra path loss.
Now I'm doing it all on my 2-year-old Sony laptop.
That's how much computing power we hams now have in front of us. All we
need is a little imagination and vision as to what it makes possible.
Instead there seems to be a contest to see who can produce the most
objections, valid or otherwise. Is this what the amateur service (or
AMSAT) has become?

Absolutely. About 14 years ago (i.e., at the beginning of the 21st
century) I made a donation to AMSAT earmarked for the development and
initial production of the low-cost ground station hardware absolutely
necessary to the success of a new digital satellite mode.
I didn't specify any particular digital mode. ANY new satellite mode
would qualify as long as it's digital and requires new ground station
hardware.
As far as I know (the AMSAT treasurer can comment), my donation is still
sitting there.

I think you'll find that the supply of both money and volunteer time
depends strongly on what that time and money will be used for. If you
think the supply is limited, you might consider being a little more
imaginative and ambitious in your goals.

I absolutely agree, but I must ask you about something you said earlier:

I'm confused. My understanding of the idiomatic expression "usher in" is
that something new and presumably revolutionary is being introduced,
e.g., to "usher in a new era".
What, exactly, will a new LEO, single channel, analog FM transponder
satellite "usher in" that none of the previous LEO, single channel,
analog FM satellites managed to usher in?
Will the tiny cubesat form factor (to which we've been relegated by the
intense competition for launches from the small satellite revolution we
pioneered) make the difference this time? If not, what will?
The most common argument I've seen for launching more analog FM LEO
satellites is that they are needed to replace existing analog FM LEO
satellites that are now failing. Is that "ushering in" something new?

I also signed up and have bought a few things but it is my understanding
only 0.5% of the purchase price of eligible products goes to AMSAT. So if
you buy a DVD worth $19.99 and it's eligible for AmazonSmile, roughly $0.10
of that $19.99 will go to AMSAT but I think Amazon waits until something
like $100 is collected before sending any money to AMSAT.

It is very sad to confirm this. In fact I was among the very first to note
the silence of VO52 and I notified Mani a few days ago. A bird meant for a
year and lasting for a decade speaks of ISRO'S brilliance in SAT designs
and launches. I would prefer to laud ISRO for this 10 yr gift rather than
get sad about this inevitable loss. Once again I thank ISRO for having
given me endless joys of going Digital with it and which I could not with
other birds.

> Will the tiny cubesat form factor (to which we've been relegated by the

> The most common argument I've seen for launching more analog FM LEO
