First of all see if the noise level increases when you power supply your
preamplifier.

That's all for now
I hope that very soon the linear transponder will be open for general use
and stay in SSB/CW as long as possible for the benefit of many users at the
same time.

Not an AMSAT-NA member? Join now to
d 3.7 dB at 435 MHz in a rural area.
If the installation is made in a suburban area or in a urban area where
the equivalent Antenna Noise level is greater and predominates then
the advantages are accordingly less.
I hope this helps.

Hi Bob, N4HY
Can you indicate to us satellite users where is the plethora of launch
capacity in the world to actually launch P3E up ?
Plethora means " overabundance"

The S1 Rx can certainly be listed as fully functional. We will await
further testing/info. on the S2 Rx.

We all hope that AMSAT-DL will find a launch opportunity with ESA and
a ARIANE-5 launcher with P3-E inside the SPELDA adapter as soon as
possible.
Pulling for P3-E ! !
