R: [amsat-bb] Is anyone working on equipment for C-C Rider?

["i8cvs" <domenico.i8cvs@xxxxxx>]

Hi Ed and Douglas

I was working very hard for two years in preparation of P3D around
a 10 watt  2400 MHz uplink and a 10.5 GHz downlink for very small
or nothing at all.

And infact my 2400 MHz uplink was used only one time during a
succesfull  S/K control station skeduled test on AO40

Actually my 10.5 GHz downlink (10450-10452 MHz ) system is
usable only to measure the sun noise to test if the system is still
working  or it requires preventional maintenance in waiting for P3E
and if P3E will use the same frequency band.

In waiting for the future both systems are getting  rust in the roof.

Many others in Europe did the same investing a lot of money for
very small or nothing.

Why do not implement in EAGLE what was impossible to use with
AO40 ?

The lesson is that I will prepare my equipments for C-C Rider only if
and only when C-C Rider will succesfully operate in orbit and not
before.
