0930 Hrs. – Meeting begins

Welcome and introductions – Joe Saddler

Purpose for meeting – Joe Saddler

20 kHz proposal and review – Bill Kelsey

Break out group (by each MHz) discussion and instructions – Bill Kelsey

Task 1. – Provide a principal and an alternate spokesperson to speak for your MHz group at the main meeting:


MHz Segment

Primary Spokesperson

Alternate Spokesperson


Jim Walls, K6CCC

Doug Marston, WB6JCD


Bill Carpenter, WA6QZY

Table 1


Question 1. - Should we change to a 20kHz band plan?

Results: All groups returned to the main meeting in agreement of 20kHz.


Question 2. - What should the implementation period be?

Results: May 1, 2000 (to be complete). All moves to 44x.y20 & 44x.y80 can start now but must be completed by August 1, 1999 or system and coordination is at risk for causing interference. All moves to 44x.y40 are not to be done before August 1, 1999.


Question 3. – What should the channel plan look like for each 100kHz block?


Old Frequency

New Frequency




No Change

General Meeting Reconvenes

The following tasks and questions were done during the general meeting.

Task 1. - Election of an arbitration committee to discuss coordination disputes. The arbitration committee is defined below:


bulletTotal of 10 persons to serve on committee, from the coordination community
bullet5 persons to serve one year, then replacements to serve two years
bullet5 persons to serve two years
bulletRequires a commitment to spend a Saturday a quarter to sit and make judgements on SCRRBA coordination disputes
bullet5 persons to make up each case panel
bulletInitial cases will be for 20 kHz coordination disputes
bulletSystem to continue as a standard coordination dispute resolution method
bulletEach member is a 440 MHz system coordinee, but is not an officer or member of the technical committee of the SCRRBA organization.

Results: Those who served as primary and alternate spokesperson in the breakout groups were elected to serve as arbitration committee members (see table 1 above)


Question 1. - How many new voice simplex channels should be added and where (currently have two at 446.000 and 446.500)?


bulletTwo (2) new channels should be added
bulletNew channels should be added between 446.000 and 446.500
bulletEstablish a remote base simplex channel at 449.460


Question 2. - How many new "test pairs" should be added and where (currently have one pair at 446.875/441.675 which will move to 446.880/441.880)?


bulletOne (1) new test pair should be added
bulletNew test pair should be added at 446.860/441.860 (adjacent to the existing test pair)


Question 3. - How many new "open repeater" pairs should be added and where (currently have eight (8) pairs with 1 in the 445, 446, 448, 449 segments and four (4) in the 447 segment)?


bulletFour (4) new open repeater pairs should be added
bulletSCRRBA technical committee shall decide where


Question 4. - Should the following 20kHz moves, re-coordination, and new coordination rules and procedures be adopted?

bulletSCRRBA will direct the group, system, or individual as to when to move and where.
bulletIt is understood that if a group, system, or individual makes the 20 kHz move on their own, without prior direction from SCRRBA, they take the risk of a possible second move at SCRRBA’s direction.
bulletTo coordinate a new group, system, or individual, the following shall apply:
bulletProper and complete coordination request on file (if applications is over 2 ½ years old must be updated and/ or refreshed) with SCRRBA.
bulletThe radio to be coordinated must be on the air on a channel identified to SCRRBA (frequency, tone, and ID) that can be found and verified by the SCRRBA technical committee without any prior arrangement (test pair or co-channeled by permission only, with another system).


bulletThe rules and procedures, as written above, should be adopted


Question 5. - Should the following procedures be adopted for use in resolving coordination conflicts?

bulletAny group, system, or individual that will not accept and implement coordination direction from SCRRBA will automatically go to SCRRBA arbitration.
bulletAny group, system or individual will abide by the SCRRBA arbitration committee decision or the conflict will be treated as an interference issue and turned over to the local ARRL OO’s for submittal to the FCC.
bulletAll SCRRBA arbitration committee members are to be volunteers from the 440-450 MHz community (cannot be SCRRBA officers or technical committee members).


bulletThe procedures, as written above, should be adopted
