[FedCom] 143.625

Bob, a google's search indicates that this frequency under the new 
narrowband mandated rebanding will become an Air Operations-Air/Ground/Air 
usage within 250 nautical miles of the base station authorization -- so most 
likely this would be AM mode.  Perhaps the user got a waiver from the 
Military Communications Electronics Board to use this frequency for another 
use.  OR perhaps it's a "rogue" operation!!!   In the distant past some 
monitors have found "rogue"  mobile ops in the 148-150.0, which appeared to 
be a joint federal/state/local law enforcement task force since they were 
able to match the voices to another federal frequency that had been active 
prior to the 2 units going to this frequency.

Note that the 12.5 khz splits below (143.6125) & above (143.6375) are both 
designated for Land Mobile Radio Support Nets (Digital/NFM) usage.

You probably will have to monitor that frequency more to try to determine 
who the actual users are.

It really is a lot of fun to search the military & federal bands (138-144, 
148-150.8, 162-174, 406-420 mhz).. Can be quite interesting to discover 
usages in one's respective geographic area.

There is a (new?) repeater output on this frequency, 143.625, in the Kansas 
City area.  So far I cannot identify it unless it's the old FEMA channel C6 
in use.  Does anyone know if this is by any chance one of the newer MARS or 
CAP frequencies.  The traffic seemed fairly informal and certainly not 
standard military format.
