I have updated my Meteor Scatter web page:
To focus entirely on setting up a USA Meteor Scatter Email
delivery system for emergency comms. We simply add RX's to each
APRS Igate, and the rest of the infrastructure exists. Done.
The new tidbit I came up with is how to cheaply get GAIN
antennas for these receivers. And the answer is simply a 100
foot long wire. . Just 100 feet gives over 12 dBi of gain in a
fixed direction. Just perfect for 6m MS!
So get that pallet of radios. I'll kick in $$$ to make sure we
can get a whole lot of radios...
