Milair Frequency Changes - 7/15/2009

The cleanout of the 380-400 MHz milair aero service continues to be replaced by LMR and wideband services. If you are not familiar with what is happening, I have written about this several times on this blog and in my Monitoring Times Milcom column. In fact, I hav some major updates on this and a new 380-400 MHz TRS in the southwest US in the September Milcom column in Monitoring Times magazine. Miss one issue and you miss a lot that is NOT published on this blog or anywhere else. A MT Express (electronic edition) sub is only $19.95 a year (one heck of a bargain). You can order your sub at http://www.grove-ent.com/page81.html.

So now it is time again for some more of our exclusive aero frequency changes, updates, listings and corrections from the Milcom MP Quik-Stop . . .

And finally from Master Mark Cleary:

"I noticed a new Approach frequency is in use at Shaw AFB today. Frequency is 225.400. 287.000 has gone silent. 385.6 was in use Sunday and is silent today."

Here is a NOTAM confirming it:

APPROACH CONTROL UHF FREQ 385.6 OUT OF SERVICE. CONTACT APPROACH CONTROL ON UHF FREQ 225.4. 12 JUL 13:17 2009 UNTIL 12 AUG 23:59 2009. CREATED: 12 JUL 13:19 2009

The area in and around 287.0000 is interesting. It is another segment of the UHF milair spectrum where AM aero services are being moved out. This strongly suggest based on previous assignments in and around this freq and past intercepts, that this may be a new wideband sub-band in the 225-400 MHz spectrum. I have more exclusive details on this in my Septemmber 2009 MT Milcom column, including some in-depth analysis of the changes in the 380-400 MHz LMR sub-band.
