ALE 

Automatic Link Establishment (station)

In high-frequency (HF) radio, the capability of a station to make contact, or initiate a circuit, between itself and another specified radio station, without human intervention and usually under emergency conditions. ALE stations are generally computer-controlled.

The Air Force has ALE frequencies in the 11 and 19 MHz bands.

Automatic Secure Voice Communications Network 

A worldwide HF secure voice network developed to fulfill DOD long-haul, secure voice (radiotelephone requirements.

I have no idea why i put this in here

SSB 

AM radio transmission in which only one sideband is transmitted.

SSB is a highly efficent modulation mode and is widely used for HF communications.

gigaflop 

A billion, i.e. , 10(9), floating point operations per second.

Only supercomputers can run that fast..idiot

worst hour of the year 

That hour of the year during which the median noise over any radio path is at a maximum.

Note: This hour is considered to coincide with the hour during which the greatest transmission loss occurs.

Type 4 Algorithm 

Unclassified cryptographic algorithm that has been registered by the National Institute of Standards and Technology, but is not a Federal Information Processing Standard. NTIA

I don't know who used the TYPE FOUR, in fact, I don't even have a HF receiver.

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.
