Not withstanding all the brouhaha over various satellite types.  I don't care if it's FM, I don't care if it's digital, I don't care if it's linear, I don't care if it's LEO, I don't care if it's MEO, I don't care if it's HEO.  To quote Frank-K4FEG, "work 'em till the antennas vaporize".  I would prefer a AO-40 (sobsob), until then I'll do what Frank suggests! 73 Bob W7LRD
