We looked at building and launching an AO-51 sized satellite with 
transponders. The launches we could find prices for were from 400,000 to 
700,000 dollars. Do you think we could raise that amount of money in 2-3 
years? No one on the BOD did. Those were all 800km or less launches as 
well. The low LEOs with transponders, like VO-52, are used by very few 
compared to the FM satellites. Furthermore, a 1-U cubesat only generates 
about 2w of DC power. That will support a decent FM repeater, but not 
much of a transponder.

We have a lead on a set of launches to an AO-7 type orbit, but we really 
need some industry type people to help negotiate for us to try to get a 
spot on one at a reasonable price. There are very few launches going 
above 800km, and they are mostly Russian. Interested parties can email 
me with their background and for details if they want to help.

If you recall we also mentioned we were working on a secondary payload 
for a large LEO that will be a Mode B transponder. We can't say with who 
yet, but isn't this exactly what you are asking why we are not doing? We 
also have a university in the Northeast working on a 3U cubesat that 
will support a transponder powerwise. This was all laid out in the 
donation letter, as well as Barry's Apogee View in the Journal.

So, the BOD isn't cramming anything down your throat. Of the three 
projects we have going, two will support transponders. The problem is we 
are in a state of flux, and everyone on the BOD thought it was 
appropriate to start small and work up, so projects are successful and 
timely. I'm sorry if you don't agree with our philosophy.

Committing to something you cannot afford to do is not intelligent or 
responsible. We can't afford a HEO right now, and this has been 
explained a dozen times a dozen ways. Unless -DL gets funding from their 
government, they can't afford the THREE MILLION dollars to launch P3E 
either. Sucks, but it's time to quit whining and face the facts.
