[FedCom] New fed channels?

[Kevin]

Not sure if this has been covered here before, but NTIA Red Book 
http://www.ntia.doc.gov/osmhome/redbook/redbook.html (section 4.3.9, 
pages 4-182 to 4-192) states that all assignments in the 406-420 MHz 
band (with bandwidths of 12.5 kHz or greater) are supposed to adhere to 
this plan by the end of the year (unless a waiver is recommended by the 
IRAC Frequency Assignment Subcommittee and approved by the NTIA):

406.1125-410.9875 MHz - repeater outputs
411.0000-415.1000 MHz - simplex
415.1125-419.9875 MHz - repeater inputs

Under this plan, repeater inputs are exactly 9 MHz above the repeater 
outputs.  Now might be a good time to start searching through the 
406-420 band in your area to see what's new or what has moved.  Again, 
the above plan applies to assignments with bandwidths of 12.5 kHz or 
greater - it appears that assignments of 12.5 kHz or less can be 
authorized on any of the above frequencies.
