[MilCom] Army low VHF FM question

[Tom Greenwood]

Larry

Is the tone actually 151.4?  At one time many years ago (I think) I recall
reading that 150 Hz was commonly used on military low band radios and that
setting a PL decoder to 151.4 would be close enough to decode the 150?

Thoughts?

Hey Dan and Mac,

 Sorry to disagree Mac, but the short answer is no -- 151.4 Hz is not the
 only PL tone used by DoD in the VHF low band. It is the most common, but
 definitely not the only one. Case in point, during an opening earlier this
 year into the NE I had an unknown DoD range control on 31.450 MHz using
 146.2 Hz PL. I have numerous other examples I have uncovered over many
years
 of monitoring skip. 151.4 Hz will get a lot but definitely you will miss
 quite a bit of activity.
