[ARC5] ZB Discussion

[Robert Eleazer]

A friend of mine who was a USN radio technician during WWII told me that both the sector codes and the transmission frequencies were changed multiple times during the day and pilots had to look at a chart they were provided with in order to figure out what code to use when.

I would presume that the encoding frequencies (IF settings) were changed too, but I would guess that happened less often.

My friend also says that the pilots were told until they received the signal, were told to note the altitude where reception first occurred, and they given charts that enabled then to equate reception altitude with distance from the carrier, presumably simply based on Line of Sight.     

Now I wonder if all of the ZB and ARR-2 installations were accessible by the pilot of a single seat fighter?  It sure sounds like it if they had to change frequencies.

Thanks for the info!
