Sorry I will attempt a re-format...

Following the Teamspeak meeting, the pertinent levels for P3E:

V Tx Phase +10dBm @ 145.895MHz into 50 ohm 

V Tx Envelope 2Vp-p into 1kOhm baseband 

U/V AGC I/O: 2V full gain, 5V full compression (output capable of ~2.5mA
drive) 

U band IF in -15dBm @ 10.7MHz into 50 ohm 

L band IF in -15dBm @ 10.7MHz into 50 ohm 

S band IF out -15dBm @ 10.7MHz into 50 ohm
