[MilCom] NASA 809

[Bryan Herbert]

373.1500 MHz is considered their primary freq. If you havent already, youll
want to add it to your list of NASA freqs.

However, much like the U-2, ER-2s also maintain radio silence during
missions except to coordinate with ATC. Every ARTCC has a 'TacSpec Use'
freq for ultra-high altitude aircraft like the ER-2, U-2, and WB-57, down
your way I believe its 296.7000 MHz.

Not long ago, Larry Van Horn published a list of known 'TacSpec Use' freqs,
its worth programming them all in. At 60,000 feet, it gives an aircraft a
radio footprint of over 300 miles.

A couple days ago, I tracked a U-2 flight on 369.9000 MHz as it flew over
the Grand Canyon, Las Vegas, and Death Valley. It then headed north,
switched to 296.7000 MHz, and continued on to Northern California. I lost
it somewhere west of South Lake Tahoe. I can only imagine what all Id hear
if I had an outdoor antenna.
