We need high power 10 meter CW or PSK stations to test
The PCSAT2 10m ==> 2m transponder asap.

PCSAT2 mission ends on 30 August (just 8 days away) and
To date, no one has reported using the 10m uplink to
435 MHz downlink transponder.  We know the transponder 
Is quite deaf, but to date, for the last several months
We have not had any reports of anyone making the transponder
Or even trying. 

We'd sure like to hear someone confirm that they transmitted
Or more and are certain that they did not hear anything.  Anyone
Can hear the downlink with just a simple 435 MHz FM rig.  The
Downlink carrier comes up just fine.  What we need are high
Signals on the 29.401 uplink.  CW, PSK, anything.

So even if you don't have a KW on 10m, pair up with an HF friend
That can generate lots of power and have him transmit on 29.401
During a pass, while  you listen on the 235.275 MHz downlink
(+/- Doppler).

Anyone can SWITCH-ON the transponder by simply sending a 1200
Packet CONNECT-REQUEST to "PCSAT2" on 145.825 uplink.
That "connection" will trigger The 29.401 to 435.275 MHz 
transponder to come up for the duration Of the connection or 
1 minute which ever ends first.

During that time, everyone will hear he downlink which is just
The audio out of the 29.401 SSB receiver.  We want to see if
Anyone can get in on 29.401 or 29.402 MHz CW or PSK uplinnk.
