Database Manager's Corner

The ARRL Repeater directory went to press on January 30, 2012. Any updates since will be included in next years publication.

We have a number of TDS forms that are overdue. Over 26% of the repeaters in our database have not been updated in two or more years. So take a minute and check your entry in the MARC Repeater Directory to see if it is time to update your records.

Dave Johnson, WD8DJB

Editors Note

Topics for the June meeting will inlcude continued discussion about the impact of creating splinter channels for narrowband digital voice operation, as well as continued discussion about ways to change the outdated methods of calculating spacing between cochannel and adjacent channel repeaters.

Meeting called to order by Phil at: 1:00 PM.

Treasurer’s report provided by Dave. Motion to accept the report made by Ken, supported by Dan, vote taken, motion carried. Ann read Dave’s report from the period of 1/31/12 to 2/28/12. Motion to accept the current report made by Jim, seconded by Fred, motion carried.

Old Business:

Phil reported that the Marc board has been extremely busy and so far has not had the time to send out decoordination notices to repeater Trustees that are delinquent on their TDS updates.

New Business:

Fred stated he went through several counties checking coordinated repeaters to see what is actually on the air. He found seven that were not on the air and one had extremely small coverage area, as low as 2 miles. One apparently had no receiver. In some cases the TDS was correct but the coverage did not meet the minimum requirements.( at least 10 miles ) Hopefully MARC can send some letters out to these trustees and have them correct the issues or return the coordination for someone else to use. Repeaters that cannot meet the minimum coverage requirement may be offered a SNPR repeater (Shared non-protected repeater). A repeater owner can be given up to 6 months to correct the problem. On overdue TDS updates, a 30 day period is given after notice before the coordination is withdrawn. Jim will help Fred with language on the notices to be sent out to the repeater trustees.
A correction by Phil, The Bylaws state that the time to correct a non compliant issue is "up to 90 days".

MARC will reimburse a Board member for gasoline used to take a long trip to investigate whether repeaters in that area are really on the air and possibly check that the location and antenna height are as reported on their current TDS.

MARC may ask for help from Michigan OO’s to determine if repeaters are actually on the air around the state.

Phil stated he would like to add a SNPR (Shared Non-protected Repeater) pair: (441.5 in 446.5 out) to the already in use (440.5 in 445.5 out). He would like to add it as a DOG resolution, instead of a bylaw change. Motion made by Dan seconded by Jim, vote taken, and motion passed. The resolution will be given the next higher number on the existing resolution list. If this frequency pair is already in use, please let Phil know. (w8ic@miarc.com). MARC has nothing coordinated on these frequencies.

Discussion on adding an application for membership to MARC on the web page. Dave and Dan will work on it and possibly add PayPal to allow easy payment to MARC.

Phil did some research on coordination separation standards. MARC in earlier years was setting up repeaters in different classifications based on their coverage area. These classifications were local, district, regional, and quadrant. The standards never incorporated a system to put repeaters closer than 120 miles. Over the years the Local classification was dropped, 100 miles is now used on 440 and waivers were permitted to allow closer spacing. Phil would like to see closer spacing on repeaters that are limited by the specified coverage area of their coordination. The district class repeater is limited to 25 miles coverage and it has a 15 mile free zone or protected zone that surrounds it (approximately 50% of the coverage area radius). Under MARC standards the next closest repeater would have to be 120 miles away on 2 meters. Based on the basic standard in the Bylaws it would make more sense to be 25+15+25 or 65 miles apart for two district class repeaters.

The next class, regional repeaters are a maximum coverage of 40 miles. That would allow a district repeater 40 + 20 + 25 at 85 miles of separation, or a regional class at 40 + 20+40 at 100 miles. Quadrant repeaters are normally repeaters built using large towers, giving them a very large coverage area. They should limit their coverage to 55 miles and have a safe zone of 30 miles. That means the closest a district class could be located to a quadrant would be 55 + 30 + 25 or 110 miles. All repeaters should be required to run PL tones (CTCSS) and the tones should be coordinated to prevent keying up more than one repeater at a time. Also, existing repeaters need to be sure that they are classified correctly based on their coordinated coverage.

The discussion was tabled and will be considered over the next three months.

Fred asked about simulcasting with more than one transmitter on one frequency. The issue was discussed but no conclusion was reached. Research is required. It appears this type system is something that may soon be requested.

Phil asked for a discussion on DMR repeaters, specifically MOTOTRBO and asked if they can be placed on splinter pairs. MOTOTRBO and similar type Digital repeaters operate using 12.5 kHz bandwidth signals. These will fit in MARC’s band plan on 440, where the channel splits are 12.5 kHz, but not on 2 meters where the splinter channels have only 10 kHz spacing. Dan and Fred will work on rewording DOG #11 to clarify that digital repeaters of 12.5 kHz bandwidth or less can occupy 440 splinters. On 2 meters only the 6.25 kHz digital repeaters can be coordinated in the 10 kHz splinter channels. (Dstar and some P25 types) The board will then look it over and vote on it when it’s ready.

an asked Corwin if he was aware of the waiver for his repeater that is currently neing initiated by Phil. Corwin was aware and stated he is happy with the waiver.

Adjournment:

Motion to adjourn made by Jim, seconded by Fred
Motion carried.
Meeting adjourned at 2:40 PM.

Respectfully submitted,
Ann Manor, KT8F, Recording Secretary
