[NLRS] Long range planning - Aug'04 UHF contest - Revision 2

Hi John,

A couple of comments to your post...

>> How about a few rovers hit the other grid corners to make more mults
available.  
Yup.  Already planning on that (at least I am).  Haven't decided which ones
yet, but its early.  "50 grids" might be a bit of oa streach, but who knows ?

AD6FP and AA6IW published a 10/24 GHz design in Microwave Update 2001 that
is pretty good.  I've got one built, and on the 18" DSS dishes, it measured
about 1.5 dB down from "expected" at Tulsa last July.  Both 10 and 24 GHz.
But that's not bad, considering all dual-band feeds are compromises.  The
only down side is that built as published, its fragile... my version is
robust, but requires lathe work.  I've already told a couple people I'd
make them the lathe bits... should I make one for you also ?
