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
