radar mile

The time required for a radar pulse to travel 1 mile (~1.6 km) to an object, i.e., to a target; reflect; and return to the receiver. Note: A radar statute mile is approximately 10.8 ms (microseconds); a radar nautical mile is approximately 12.4 s. The time for any other radar unit distance is readily determined, such as the radar meter or the radar kilometer. NTIA
I listen to propagation mapping radar on the 27 MHz freeband.

APCO P-25

New digital modulation type, labelled as "APCO Project-25" P-25 pretty much is the same modulation that cell phones use. P-25 is supposed to give better voice quality, but there really is no differance. Plus I need to buy a new radio scanner now.
There are two types of P-25, 3,600 baud and 7,200 baud speeds.

Agent Orange

orginally classified as a "defoliant" but the US Government found out that it is better at killing VC soliders and giving Americans prostate cancer.
