CT Spectrum Management Association

We all know that constructing a repeater is a great deal of work, and ensuring that the repeater's frequency is not going to have to change will save time, money, and a great deal of frustration.  Crystals are purchased and filters are tuned; changes to these are not something that anyone would want to have to do several times due to coordination problems. For the existing coordinated repeater trustee, having a new repeater pop up too close on the same frequency or even 15 or 20 KHz away can be an uncomfortable surprise.

To try to prevent just such a surprise, we need to ensure we have all of the technical information about your system.  This will allow us to run coverage plots to ensure we can adequately evaluate any new cross-coordination.  Without accurate, complete technical data, it becomes nearly impossible to protect you.

Please help us help you. Your coordination is a valuable thing. Please don't let it be compromised by inaction. If you don't understand any of the questions or details about the update form, please don't hesitate to contact us. We'll be glad to help you with your questions.

Please fill out these forms as completely as you can.  Details like your exact location, transmitter power output, duplexer type, any extra filtering, feedline type and length, and antenna type and height are tremendously important.

Please read the CSMA Guidelines and fill out the appropriate form.

The CSMA Coordination Form form should be used for all new coordinations and emitter changes.

The CSMA Coordination Update Form should be used update existing coordination and emitter information.  Repeater information should be updated every three years, even if nothing has changed.
