-----------------------------
4D's Priyom Designation System aims
for an easy to use, detailed, and diverse catalog of HF
communication systems and utility radio stations, military,
domestic, or intelligence. It divides stations into large
categories depending on the station's usage: military, diplomatic,
aero, marine, intelligence, or other utility. It then further
divides the station into languanges or data mode, then a number
assigned to the station itself. Afterwards, an a, b, c, ect would
be placed in order to showcase a station's variation. If an X
follows, the station is no longer active.
