Re: [amsat-bb] Not so stupid question

[Jim Sanford <wb4gcs@xxxxxxxx>]

Guys:
I agree with True North.

If you have enough visibility:  Polaris is always within a degree or so of True
North, if you can see it, you can find the tree/whatever that's under it from
your antennas.

The good news:  At least at 2m and 70cm, a degree or 3 of error won't kill you
.. . .

Good luck!
