Finished testing the 2m system and the 1296 system and have the array 
raised back up.
2m: 4x M2-2mXP20 yagis for 21.3 dBi gain + 150w  (0.1 dBNF preamp)
33cm: 33-element loop-yagi with 18.5 dBi gain + 5w (0.26 dBNF preamp)
23cm: 45-element loop-yagi with 20 dBi gain + 6w (0.30 dBNF preamp)

also:
6m: 3-element yagi pointed SE + 125w (working on tower for 6-element 
rotatable yagi)
223.50 FM: 2x CC 220-11 yagis 12-dBi gain + 60w (0.7 dBNF preamp)
146.52 FM: 11-element yagi 13 dBi gain + 15w or 130w (0.5 dBNF preamp)

432 has some problems so not QRV.  Maybe get it fixed during the day, 
tomorrow: 11-element yagi + 20w (0.7 dBNF preamp)
