[NLRS] DEMI Transverters?

[Scott]

Do the Down East Microwave transverters for say 1296, 2304 and 5760 use
outboard Local Oscillators?  I assume they do and if so, are they all in the
540-580 MHz range?  The reason I ask is that I plan to build for all of the
above listed bands and want to see if one L.O. can pull multiple duty with
appropriate multipliers after it.

Thanks!
