January, 2008:

This is the first in what is planned to be a regular series of emails intended to keep you informed on activities at T-MARC.

The T-MARC board that you elected in November, 2007 has met twice and will meet once more before the general membership meeting on February 17. At the first meeting, the board elected the following officers:

President: Dave Prestel, W8AJR
Vice President, Technical Operations: Bill Conaway, W8HNT
VP Public Affairs: Al Brown, KZ3AB
Secretary/Treasurer: John Elgin, WA3MNN

The following is a brief list of the actions taken by the board to date:

* As part of his duties as our Public Affairs Officer, Al Brown has taken over care and feeding of the T-MARC web site. The databases on the web site have been updated and are being maintained regularly. The link to send mail to the board is operational.

* The membership database has been updated with information received at the November general meeting and is posted on the web site.

* The list of coordinated repeaters is being updated and will be made available on the web site.

* We divided up the list of questionable repeaters, that is the ones for which we have not received any communication from coordination holders, among the members of the board and are in the process of verifying their status. As a result a number of frequency pairs have been de-coordinated. Details of the de-coordinations will be posted shortly. There is a large number of repeaters on this list. We are giving first priority to two meter and UHF repeaters as this is where the greatest demand for new coordinations exists. If you know the owners of any of the machines listed and can assist in having them contact us, that would be appreciated.

* Board Member Bryan Dorbert, N3ST, has agreed to be a full time assistant to Bill, W8HNT, in resolving coordination issues. They have been working diligently on all of our open issues and have been responding promptly to new requests as they come in.

* Board Member Larry D'Anna, WA3KOK, has taken on the responsibility to get our incorporation status renewed. He has been in contact with the government of the District of Columbia and is contacting other jurisdictions to compare the relative costs and benefits. We expect to have a final report on our incorporation at the membership meeting.

* The board is still considering the issue of holding regular coordination meetings. These would be held to benefit those who have requested new co-ordinations or who have raised co-ordination issues to be resolved and would be held in locations convenient to the folks whose issues are being discussed. Our final recommendation will be reported at the general meeting. * We have begun coordination of D-STAR repeaters.

That may look like a short list, but it represents a lot of work by the members of the board. They're volunteering their time, just as you volunteer your time to the repeaters that you operate and use. Your support and patience are truly appreciated.

The next general membership meeting will be held on at 1:00 pm, Sunday, February 17, at the Historical Electronics Museum. This is a date change from the February 10 date originally selected at the November membership meeting. The agenda for this meeting will include the following:

* Report on our incorporation status

* Report on the status of the questionable repeater list

* Creation of band plan recommendation committees for 900 MHz and 1.2 GHz, if necessary. Chairpersons and membership for these committees will be sought from the general membership.

* Creation of a D-STAR coordination plan recommendation committee. A chairperson and membership for this committee will be sought from the general membership.

Note: T-MARC has created a membership mailing list. The contents of this announcement was sent in a message to everyone on that list. If you did not receive the message and believe that you should have received it, or, if you wish us to use a different address for you on the list server, please use the email button to let us know.

Over the past year  this site has been under going several changes. I have implemented the on-line Frequency Directory in a more favorable view. I have broken the database into smaller chunks. This enables Users to access these areas much faster. The pages are white with black letters, this ensures no printing problems for users. Changes to the database have also been made according to the clubs and individuals email requests. Our database can only be as accurate as the information that we are given.

The on-line directory page also now includes the acronyms from the ARRL Repeater Directory as well as a complete list of the CTCSS tones and the associated Motorola codes.

The final item that was added this year was the on-line club and members list. Some of the pages are still under construction and they will be updated soon. Please check your club or personal information and notify the Web Master as soon as possible with any changes.

If you find an area of interest that T-MARC should include on its web site or you know of a link to additional information that would be helpful to members or new people then please forward the information to me. I want to make these pages very informative and useful for everyone.
