Hi Piero, HB9DSU
The future will be again bright for all of us and for the Amateur Satellite Service only when tanks to AMSAT-DL P3-E will be placed in orbit.
Be patient and prepare for the future.

transponder,
<<SNIP
There seems to be a proliferation of satellites using the Amateur bands as cheap down link frequencies, and using Radio Amateurs as a cheap way of collecting their data. It is MY personal belief that a satellite should only use our hard-earned and much coveted frequencies if they REALLY do carry an Amateur Radio payload... I.E. a Transponder! , or, at the end of their commercial life, should be put to real amateur use, I.E. a Transponder, promised several times but not often delivered.
OK there are many out there who get satisfaction from getting signals from anything that is orbiting, to them, I raise my hat BUT.. if it is in an amateur band, it should be a REAL amateur satellite.
This is my view, and I stand here to be shot down.....

John:
I'm not going to shoot you down. With some moderation, your views represent many of us. But I want to suggest another way forward, one that is audible on our radios right now. Delfi C3 is a project that makes a fair trade between the college projects' desire for data from our unequaled network of receiving stations and the amateurs' desire for a transponder. Even if a few other cubesats go up at the same time -- and I have to confess that as a university professor (though in the humanities), I love to collect telemetry from these, because I can imagine the enthusiastic young people behind them -- even if these others without a transponder go up at the same time, we stand to benefit greatly (admittedly, in LEO) from this sort of trade-off.
I understand William PE1RAH is working on a transponder design that will fit within the cubesat format, too.
Here's my optimistic summary (again, apropos LEO). Cubesats have created a low-cost, frequent ride to space. The experimenters have developed a standard ejection system, and a well-known set of parameters for power, etc. We know a linear transponder can ride on one of these. At the same time, I'd say that on the whole our groundstations are improving (with antenna design and low-noise preamps) that we can compensate slightly for lower power in space. We should get behind these cubesat projects and be in the position to offer a SDX transponder that can, during their science phase, be used as a data downlink. Here: it's yours. Just let us turn on the transponder in a year or so.
I'll end with a challenge to continue this thread. Cubesats tend to be launched into low LEO orbits. What experimental schemes could be put on board to boost their orbits, say to the height of FO-29? The ION cubesat was meant to look into alternate propulsion. These probably should not be tried-and-true systems, since such would not be of interest to the cubesat research teams. We offer the comms, we cheer on the science, and even if the boost engine doesn't work, we have another low LEO transponder.
73, Bruce VE9QRP
I agree.
An orbiting telemetry transmitter is of little use to very few and on no use to the majority.

While I too like to see transponders, I do not like to see all the negativizim, hate and rabble-rousing against those who actually get something into space. The self-richeous nay-saying comments are about as practical as these:
"Those HF contesters should not be using the Amateur Bands, they should be passing useful communications or traffic!"
"Those Traffic passers are not real amateur operators, because they will not respond with QSL's!"
"Those old fud rag chewers on HF think they own the frequency. They should let others use the frequency for more useful communications"
"Those FM commuters are just wasting air time, saying the same old thing every day. Why don't they just use a cell phone!"
"Those AM guys are just wasting 6 KHz of spectrum, they should be made illegal on the amateur bands"
"Who wants to look at all those SSTV pictures, Its just the same old post-card! They should not be using 3 KHz of bandwidth for such stupid applications"...
"Those Winlink guys are killing amateur radio by turning the bands into an automatic communications system."
"Those Echolink and IRLP links are bad for ham radio. Why don't they just use HF or a phone if they want to talk to someone far away."
"Those Radio control Airplanes operating on the Amateur band should never be there, they are not communications".
"Those experimental Balloons just transmit pictures and telemetry, without a transponder, they have no purpose in Amateur Radio"
And on and on...
Face, it.. Ham radio is as rich in applications as there are innovative and resourceful people. If you want something done, then go do it. If you don't like what others are doing with their hobby, then get out of the way.
Public negativizim and constant complaining never accomplishes anything except darken our collective hobby. Save that for the politicians who are supposed to respond to their constituents. For a hobby that is just the collective "us" with each licensed individual having the same equal opportunities as everyone else, complaining about what others do is just pointless.

Actually, I would like to put a different slant on it. Collecting the data, even from a purely scientific mission, gives hams a chance to provide valuable downlink time for LEO satellites at all times. As for me, this gives me the feeling of being part of the scientific process.

Hi Bob, WB4APR
You cannot get out of the way those Amateur Radio users actually requesting OSCAR's Satellites with on board transponders because the Amateur Satellite Service started when in 1972 OSCAR-6 was launched and thousand's of the above maltreated and by you offended HF users decided to abandone the Amateur Service to enter into a more bright and promising Amateur Satellite Service. The above thousand's HF users invested worldwide a lot of money and a lot of efforts to convert their HF stations into VHF/UHF/SHF Satellite Stations with the purpose to get a more communication efficiency against the problems due of propagation using short waves. Without the above prerequisite the Amateur Satellite Service never would had spring up.
Read please this "Brief History" written into page-1 of the AMSAT-UK OSCAR-13 Operations and Technical Handbook 1989
"Amateur radio satellites have gone through three phases; phase 1: experimentation to find the possible; phase 2: long life, low orbit satellites to gain experience; and phase 3: high altitude orbits with complex transponding and control systems.
Phase 1 started when OSCAR-1 was launched on 12 December 1961 and phase 2 was led by OSCAR-6 in October 1972. Amsat's first attemp for phase 3 (the satellite known only as phase 3A ) failed when the experimental Ariane rocked plunged into the South Atlantic in May 1980 . Amsat second attemp for phase 3 partially succeeded in June 1993 when OSCAR-10 was released into space . The world's radio amateurs after more than 10 years of low orbit satellites and associated short visibility periods, at last tasted Amsat's policy of equivalence to a permantly open 14 MHz band with practically world wide communications.
OSCAR stands for Orbital Satellite Carrying Amateur Radio and a satellite is a package equipped with solar cells, batteries, receivers, and transmitters, aerials and control electronics. The batteries are charged by the solar cells whenever the satellite is in sunlight. Signal received in part of one amateur band are retransmitted in part of another amateur band. Unlike terrestrial, single frequency, analog repeaters ,the satellite relay system (called a transponder ) will translate linearly any type of narrow-band signal such as CW, SSB, RTTY, NBFM, or AM although only the first four are recommended, being power-efficient and RF low duty cycle -------------------- Bob, This is why the above thousands Satellite Experimenter's and User's mostly coming from the HF are actually waiting for P3-E and her transponders. Read again please:
".................when OSCAR-10 was released into space . The world's radio amateurs after more than 10 years of low orbit satellites and associated short visibility periods, at last tasted Amsat's policy of equivalence to a permantly open 14 MHz band with practically world wide communications."
I hope that the original unchanged AMSAT's policy will be now clear for you.

Seems that IF only a transmitter was included then you must not have taken enough interest in seeing that more was included. Next time, you should be willing to step up and ensure that a transceiver operation is include. Try addressing the issue before the satellite leaves the launch pad. If you still have no results, then you have a platform to complain from.
I'm also a bit concerned regarding the comment about "our frequencies". Most of these satellites appear to be operating in the UHF spectrum which amateur radio is not the primary or only group with allocations.
