Welcome to the MARC Newsletter a publication of the Michigan Area Repeater Council. This news letter is published quarterly in conjunction with the quarterly business meetings. If you prefer a non-columnized version of this newsletter click here for the wide version.
The September meeting is a physical meeting to take place in the Lansing, MI area.
Many requests for coordination are of the digital repeater type. This trend seems to be building. MARC has already coordinated or provisionally coordinated D-star, Mototrbo, P25 and Fusion type digital systems. Any of these systems can be coordinated on a full channel. These are the basic channels like 146.760 or 444.050. If your club or personal repeater is on a full channel like these, you can switch to one of these digital types at any time. Please submit an update TDS, so we can include the access data in the directory. The channel requirement for the digital repeaters is not as wide as standard 5 kHz FM analog that needs 16 kHz of total bandwidth. (+- 8 kHz). The digital signal transmissions are narrower than the FM analog, typically 6 to 9 kHz, but receivers for the fm analog are quite wide.
MARC has placed many digital repeaters on splinter channels. These channels are placed half way between analog channels. Ex. (444.050 - 444.0625 – 444.0750) 444.0625 is the splinter. The splinter channel works well with the narrow band digital signals. The need for caution exists because the wider receive bandwidth of existing analog rigs would hear the digital signal if they are in relatively close proximity. MARC has used a 50-mile minimum spacing between the splinter and the adjacent full channels for this type of coordination. This has been working for many years. Resolution #11 and the history of changes to it are available on the MARC website by-laws resolutions.
The September meeting in Lansing is open to all and all are welcome to attend. At this meeting, MARC will hold elections for vice president, treasurer and a board member. A vote will also be held on a proposal to adopt the standard for splinter channels into the bylaws. If you have any input on this issue, would like to run for an office or are just curious, please attend the meeting. Directions are available elsewhere in this issue.

MARC Meeting Minutes
Date: June 6, 2015
Meeting called to order by Phil at: 1:03pm.
Motion to approve minutes from the March 2015, meeting was made by Jim,
seconded by Dave, vote taken, minutes approved.
Jim made a motion that Resolution 11 be voted on for inclusion into the bylaws at the September meeting in Lansing. Seconded by Dave, vote, motion carried.
Dave offered to set up the annual meeting in September at the Delta Twp., fire hall. (Lansing meeting).
Jim sent out a letter to the WD8DAR repeater 444.425 noting that it's coordination will be dissolved in 30 days from receipt of notification, pending on a response to the letter.
Dave brought up the fact that 36 to 37% of TDS's are delinquent in submitting their required updates. Many of these are very old and some of them should be de-coordinated. Any board member is authorized to send a de-coodination warning letter (certified) to a delinquent repeater trustee. Send an email including a copy of your letter to email@example.com so that all board members will receive a written record. If you determine that the repeater is no longer complying with its coordinated parameters, based on the response or no response to the letter, send an email to firstname.lastname@example.org indicating the effective date of the de-coordination. At that point, Dave will move the coordination documents into the inactive file. This will free up a pair of frequencies in the data base for a new coordination.
In September, elections will take place for the offices of Vice-President, Treasurer, and one board member. Ann and Phil will make up the election committee. Dan, Dave and Jim agreed to run again as incumbents. Please submit your name to email@example.com or firstname.lastname@example.org if you wish to be a candidate for any of these positions.
Motion to adjourn made by Dave, seconded by Jim.

The ARRL will be changing the format of it's Repeater Database that MARC updates. The Repeater Directory publication will also be changing starting with the 2016 Edition. Here are the changes the ARRL is making that may effect your entry:
We did not provide input to these ARRL changes. We will be making the necessary changes to submit this data, however, it may be some time before we can change our TDS form because of it's current use in our custom software. In the interim, please include any EchoLink/IRLP/AllStar, link or other significant information in the comments field of our current TDS form and we will do our best to include this information in our submissions to the ARRL.
We have a number of TDS forms that are long overdue, 37% of the repeaters in
our database have not been updated in two or more year’s. So take a minute
and check your entry in the MARC Repeater Directory to see if it is time to
update your records. We are attempting to respond to every TDS form we receive
by return email so you know that your form has been received and you have a
copy of what was submitted. If you submitted a TDS and did not receive an
email response please contact us at email@example.com.
