[Motorola] Was Encoder, Now MICOR and Channel Elements....

[Walter Howard]

Spectra's are NOT capable of narrowband.
AstroSpectra's are.

And 'narrowbanded' MICOR's will not be on the NTIA acceptable equipment
list.

John; I don't understand your comment about the MastrII's being hard to
find.
There are TONs of perfectly usable MII's coming out of commercial service.

My agency just sent 20 to surplus, and we'll be sending over 100 more from
various state agencies in the next 3 years.
And I know we're not the only ones.
