Dear Andrew, Sorry for the delay but I hope this helps. Its not for the MSF but rather it's close cousin, a hundred watt UHF MSR2000 (same power supply). I recently had the occasion to build a 12 hour UPS which required my assessment of watts usage versus RF watts out. Listed below are my findings.
Watts
Recieve CDX = 70
TX 10W = 218
TX 20W = 269
TX 30W = 321
TX 40W = 354
TX 50W = 404
TX 60W = 430
TX 70W = 480
TX 80W = 512
TX 90W = 549
TX 100W = 567
