[amsat-bb] omnis for sat work?

[Ron VE8RT]

Hi Brad,

   your set-up is do-able.  I'm putting together a K3NG rotator
controller for my own station, but it may not be needed to start with,
only the southern part of passes would be of interest.  I'm curious
what the rotator model is.  I'm using a Ham IV that I re-built myself,
using aviation lubricants, its been colder than -40 and even then it
worked flawlessly.  Going from pictures of Cambridge Bay, there doesn't
appear to be any issues with terrain so a short mast should do.

   I use an 8 el quad on 2M and a helix antenna, left over from AO-10,
AO-13 days, on 70 cm.  The quad's beamwidth is narrow and if the
antennae track most satellites they're workable to about 2 degrees
above the horizon without a pre-amp and 10W (less coax losses) on
transmit.

   Its a good time to work on the shopping list, as she has nothing the
list will include everything :-)  I wonder what 6 metres is like up
there, she is well north of the auroral oval.
