RE: California Amplifier 130415 mods ?



Are these available? Also, will they be useful if another HEO satellite
(elliptical orbit) becomes operational in the future? I thought that P3D
was SSB on the S band downlink.

Yes it is different. Not only is the output frequency band different but
it
has "disk yagi" built onto the front of it...
