I think we should try to build LEO's with both kinds of transponders on
board. The FM birds are great for getting newbies interested in the sats
and with a little encouragement from the "old hats" they'll want to upgrade
their equipment to work the more challenging Linear birds. That serves 2
purposes: 1. it gets more hams in general involved with the sats, and 2.
It gets more hams equipped and able to work the linear birds. That will
mean a larger base of hams that will contribute to projects and push for
HEO birds.
Also, I wouldn't discount the commercial launch operators just yet. They
are at the beginning of the curve when it comes to regular launch
activities. As they get further down the road, the costs will scale back
significantly. AMSAT-NA is a non-profit is it not? I can see a day in the
future when we could conceivably get a launch opportunity for significantly
less cost because of the non-profit status of AMSAT. Assuming the tax
breaks involved don't get slammed by this or a future administration, this
could position AMSAT for all kinds of future opportunities.
It's a waiting game at this point. Lot's of things could radically change
in the very near future, but that's no reason to sit around twiddling our
thumbs moaning about the "good ole days" of AO-40. Push forward or push up
daisies! It's our choice!

I've enjoyed reading this segment and I wasn't going to touch it, but this
one makes me want to chip in my two cents.
Granted, I'm not up to speed on what ya'll have done or what you haven't
done.
But we used to use a ucc1 in the navy to receive messages.
http://www.virhistory.com/navy/rtty-mux-ucc1.htm
It would allow us to receive something like 16 or 32 separate traffic
channels on one frequency.
Wouldn't it be possible to develop something like that in satellite
communications?
I ask because if you were to do it, you could substantially increase the
amount of channels that you could process?

If we want the most "bang for the buck", it would be something that supports
the most QSOs per watt of solar power. Since most hams have computers,
something that supports half a dozen PSK31 sessions would suffice. Given the
new open-source voice codec you could also make something that supports
multiple digital voice QSOs with less power than now required for analog FM
or SSB.

The satellite could collect the individual uplink signals and package them
in one downlink. One TDM downlink would use much less power than FDM
downlinks and would fit in the bandwidth of existing amateur receivers. Once
you have DSP in the satellite, there are a lot of possibilities.

You also could develop a whole new line of amateur radio equipment.
By that, I mean that ham's could use existing transceivers, and for
satellites that were equipped, they could buy this box that would allow them
to transmit on channel ?? of frequency ?? and the same on receive.
Of course, that might present a co-ordination nightmare...

regarding this latest AO-40 (sobsob) thread...If you do any satellite
operation you should join AMSAT....if you join AMSAT you should contribute
whatever additional you can afford, there are monthly plans available
http://store.amsat.org/catalog/index.php?cPath=35&osCsid=f01nlhgn764rav8s261ip
o2fn6 . If it's all about the bottom line (money), make it available. If you
don't like AMSAT or the direction it is taking, start your own or join the
BOD and fix it. It is essential I/we trust those in charge. I keep my AO40
QSL cards handy and show them to visitors, and I tell them yes it'll happen
again.

I'm almost fifty one years old and I'm now convinced that we will not
see another HEO in orbit in my lifetime...if ever. The economic
environment to do it just doesn't exist anymore. AMSAT has as much as
told everyone that by abandoning their efforts and concentrating on LEO
cubesats. No one is going to come out and say that we absolutely will
never have one, they like to keep that glimmer of hope alive but the
writing is on the wall. No one wants to be wrong more than I do but
I'd bet you P3-E never flies.

I know how much the FM satellites are loved by certain segments of the AMSAT
community, and FOX-1 will serve that community beginning late next year. In
addition, many universities are building 2 meter FM satellites as part of
their aerospace engineering curriculum.
The problem with the FM satellites is that only one station at a time can
access them, during field day I listened to several passes and I did not hear
one complete field day exchange during any of them. They are just too limited
to serve as a pathway for growth for AMSAT.
I have also read many recent posts regarding the late, great AO-40 and how
much the long distance DX that it provided is missed. The S-band downlink for
AO-40 performed well and was quite inexpensive for hams to acquire. It is
simply a myth that microwave equipment and antennas represents a difficult
entry path to amateur radio.
In the event that AMSAT should find an opportunity to place a Cubesat into
HEO, it will not be able to replace the performance of AO-40, but it could
provide the long distance DX opportunities for those stations that are willing
to make a modest investment in equipment. I am sorry that we cannot provide a
HEO DX satellite that anybody can work with an HT and an Arrow antenna, but we
are limited by the laws of physics, the size of the solar arrays, the antenna
gain and the link budget from HEO. We can only fit so much stuff into the tiny
little satellites that will be available to us in the future.
If we build a small HEO satellite some people will be excluded from using it.
We are not trying to exclude anybody but those are the facts of life as I see
them. If you want a HEO DX satellite it is going to cost you some money to
equip yourself to work the satellite with its limited power output and link
budget. This is not because we want to exclude anybody, this is doing what we
can with the launches that are going to be available to us in the future. I
don't see the value of bringing new hams into the satellite hobby if they make
a few QSO's and then grow tired of the limited capability of the LEO FM
satellites. To attract and keep these hams we must provide something more
challenging and more useful for communications. That doesn't make us elitist,
but until somebody writes a $10 million dollar check to AMSAT, that is what we
can do and it is better than disbanding the organization and giving up because
we can't do magic on our shoestring budget.

The short answer to all these "why are we building FM satellites" comments
is that the #1 operatation reason to build and FM satellites is that they
provide an easy way for anyone to enjoy a satellite contact. Yes there is
field day, one day out of the year. Given several operating FM satellites
in orbit of AO-51 performance, it's feasible that at least one per day will
provide a nice, comfortable opportunity to talk. This is important to grow
the hobby and to provide an easy entry-point for people into satellite
operations.
However, the #1 technical reason to build any satellite right now,
regardless of FM or linear RF capabilities, is that the RF communications
part of the satellite is only one part of the satellite. Is the RF
down-link crucial, yes, but so are the solar panes and the Maximum Power
Point Tracker for example. Without those, a perfectly functioning linear
transponder is useless because we all know that you need electricity to
actually turn any of the electronics in the satellite on, including the
communications system. The Internal Housekeeping Unit (IHU) is also
extremely important from an operational standpoint. It allows health and
status telemetry to be obtained from the satellite to best command and
configure it for optimal use as it ages or enters different periods of
orbits.
Regardless of the form of communications package, on-orbit operation of
systems build heritage and with heritage comes confidence in the design and
with confidence in the design we get satellites that last a long... long..
time. That tends to keep satellite operators happy! While I'd be against
this, and I'm sure most of us would be... it would still be beneficial for
AMSAT to fly a telemetry only satellite to prove subsystems for a future
comms satellite from a purely technical viewpoint. There are many
subsystems that would be exactly the same on a telemetry only satellite as
a linear transponder satellite.
Point is, flying FM satellites is extremely beneficial to any future
satellite be in FM, Linear, etc. By standardizing with the CubeSat
standard, AMSAT can make incremental improvements on each satellite and
envelope more daring/complex missions as subsystems obtain flight heritage.
