[Hallicrafters] OT: Aircraft Band

[Misic, George J.]

Another reason for staying with AM; there has always been a large installed base of equipment operating AM.  Additionally, AM equipment is simpler, and less critical to tune, as pointed out by Craig.  In most applications and conditions, the range provided by simple AM equipment is very satisfactory, due to the line-of-sight nature of aircraft communications.

Q - Why was God able to create the World in only six days?

A - No installed base!

1) AM is much more tolerant of off-frequency tuning than SSB. Aircraft 
radios are subject to high vibration and shock abuse in harsh 
conditions, making the relative precision required of sideband 
transmission and reception difficult to maintain.  Aircraft radios are 
purposely simple and rugged.
