Presentation of Recommended Changes to the Southern California 222 – 225 MHz Band Plan
Location: Sierra Room
Date & Time: Saturday, 12:00 to 12:50
 

The Southern California 222 – 225 MHz band plan has not been changed in several years. Over that time the user demands have changed as new technologies appear and interest in the older technologies fades. After measuring actual activity on the 222 – 225 MHz band, Bob Dengler has proposed changes to the current plan. These recommendations have been reviewed by the 220SMA Coordination Board who came up with additional important suggestions which have been incorporated in the recommendation. At the time of this writing, there is one outstanding issue which is awaiting measurements of band activity on a specific frequency.

The recommendation’s major change is to add designated frequencies for “automatic communications” modes (e.g. IRLP, EchoLink, etc.) and to increase the number of available link pairs. The number of available digital channels has been reduced reflected reduced usage of this mode.

This presentation is intended to acquaint the amateur radio community with the recommendation so the community’s views can be aired before presentation to the 220SMA membership for approval in October. After a short presentation, Bob will respond to questions from the audience.

In addition to being a member of the 220SMA and SCRRBA, Bob is the Chairman of the Two-meter Area Spectrum Management Association (TASMA). Three years ago he led the effort to update the Southern California two meter bandplan by conducting extensive monitoring of the band & drafting a new bandplan largely based on that monitoring. The resulting updated bandplan now incorporates band segments for new technologies like internet linking on simplex frequencies and wide-split in-band portable repeaters.

Bob has been a licensed ham for 29 years & has spent most of that time on the VHF & UHF bands, building dozens of repeater systems on the 2 meter, 220 & 440 MHz bands. He has been the amateur technical & frequency coordinator for all 21 City of Los Angeles Marathons.
