[grc] How 'clean' does the power from a back-up/emer generator need to be?

[shhhhh]

Hey tech/elec/engr people!

Because we live in a rural and somewhat isolated area, and because we 
are working with the local vol fire dept, and because icy storms happen 
and big wildfires get going every late Summer, and not everybody here 
has access to The Innerwebs, and because we'll be the only local radio 
station, we need to build a resilient radio station with redundant 
systems-- but, like most of us, we don't wanna spend money if we don't 
hafta. So, we need expert advice!

1) We're thinking of having a single POTS/landline *and* GSM-to-analog 
service (or maybe VoIP service, but the only telco ISP here is somewhat 
unreliable) and run 'em both into our office and studio, and in the 
studio, connect both into our brand-new Allen & Heath XB2-14 board, so 
we can use either. Too complicated? impossible? doesn't solve potential 
problems?

2) We need back-up power at the studio and txmtr site-- how 'clean' does 
the power supply need to be at each place? Do we need a pricey Honda 
inverter generator in our little txmtr shack? What about electromagnetic 
'noise' as well as regular ol' auditory noise there in that tight space? 
What about heat buildup in there? (I guess we can always install a small 
fan....) How important are the same concerns for the studio backup? 
We're thinking we'll install it in a separate room, of course, and vent 
the exhaust to the outside. We think propane or natural gas is better 
than gasoline or diesel, but "bi-fuel" (e.g., runs on propane or 
gasoline) might be best?

We've received differing advice, so we're gathering more opinions-- 
hopefully, based on experience.
