Hi Domenico,
first of all the P3E 'P5A transponder' is a team effort: you may
find the members here:
http://www.rats.fi/rats/amsat-oh/
Regarding the frequencies, you should be able to decipher the
most important information from this ecrypted document, or
alternatively you could try your luck with a translator that
attempts (!) to handle Finnish to your language preference:
http://www.rats.fi/rats/amsat-oh/p3e/
There are significant frequency scheme challenges (check out the
complexity of the block diagram, being necessary to maintain the
coherent uplink/downlink ratio of 30:7), but I think the final
frequency plan is fairly satisfactory.

Hi Kauto, OH2LFM and Michael OH2AUE
Congratulations to both of you and expecially to Michael OH2AUE
the designer and builder of the X band transponder
I have seen your OH2AUE P3E transponder demo video and I hope
that the downlink is in the same X band frequency 10450-10452 MHz
as on AO40 because I have my homebrewed downconverter and a
60 cm dish with Chaparral feed tuned for the above frequency band
since AO40 but unfortunately never used because of AO40 problems.
I hope to use it on P3E as soon it will be in orbit.
Please let us know more details on downlink frequency band as well
output power and antenna that AMSAT-DL plan to use on P3E
Thanks

Just went through my old ham camp videos..
Here is OH2AUE with a P3E transponder demo at SRAL summer camp
2011. In Finnish, but images do the talking :)
