TASMA and the 2 Meter Band Plan

[KC6ZGG]

I have been hearing some misinformation about who makes decisions about how HAM Radio frequencies are designated for use.

In Southern California TASMA is the local Frequency Coordination organization.

"TASMA is a volunteer organization of amateur radio operators whose goal is to minimize interference and maximize spectrum usage in the bands we serve. This is done primarily by recommending frequencies for repeater operation and the development of band plans. TASMA also attempts to mediate any interference issues and assist the repeater owners when possible." http://www.tasma.org/

They publish several documents including the 2 Meter Band Plan. which can be found here. http://www.tasma.org/2014-bandplan.pdf

You may notice some simplex channels have been channelized which is why the Wrightwood simplex frequency was changed earlier this year.

TASMA has also designated a split frequency repeater pair. This can be used for emergency or events on limited basis. Details about use of the split pair is in Band Plan document.

There are 2 Portable Emergency Repeaters available to be deployed in the Wrightwood area based on this coordination from TASMA.

I hope you find this information useful and that you may have a better understanding of the frequency coordination process in Southern California.

To follow Keith's lead, and to add some clarification to avoid any confusion, TASMA is the coordinator for the "2 meter" band activities, which is made clear by the thread Subject, but the text could be misleading.

The 220 MHz band is coordinated by 220 SMA.  They can be found at http://www.220sma.org/

6m, 10m, 420/440, 902, 1240, and all microwave amateur radio bands are coordinated by SCRRBA.  They can be found at http://www.scrrba.org
