IARU-R1: Global APRS Harmonisation and Satellite Coordination

IARU_Region_1_logoThe IARU Region 1 Interim Meeting was held April 15-17, 2016 in Vienna. Minutes for the C5 VHF/UHF/Microwave committee are now available.

Some 70 delegates from over 20 Member Societies discussed a wide range of issues in the VHF/UHF/Microwave, HF and EMC Committees. Recommendations from the meeting will be considered by the Region 1 Executive Committee at its meeting in early May 2016. If approved by the EC, these recommendations will become interim Region 1 policy until the next General Conference in 2017, at which time all Societies present will have the opportunity to ratify the proposals.

Among the key items in the minutes are:

4.1. Report of satellite coordinator C5_04
Graham Shirville G3VZV presented the report of satellite coordinator. G3VZV emphasized that the frequency coordination between the three Regions has to be improved for avoiding interference incidents like PC-Sat and some of the XW2 satellites.

Due to current reports from MS about some observations of harmful interference, RSGB is asked to prepare a statement for publishing to inform MS and members how to take care.

C5 chairman is asked to bring up the issue on EC meeting, because further AC action is required.

5.2. Band Planning 5 GHz: C5_10
VIE16_C5_Rec_06: To correct the satellite segment the table in chapter 4.9 by deleting “5790”, inserting “5830” and adding the footnote: “Any wideband system shall protect narrowband applications”.

6.1. General matters: C5_26
VIE16_C5_Rec_11A: To discuss an even more extended [Grid Square] locator system that is used for ATV (including IARU ATV contest) and for other purposes by using the Wiki and prepares a document for GC 2017 if necessary. (Note this will clarify the definition of 10 digit [character] locators used for microwaves etc see example at http://no.nonsense.ee/qth/map.html )

7.2. APRS Harmonisation: C5_41
VIE16_C5_Rec_23: The C5 chairman to answer Regions 2 and 3 that:
• 144.390 MHz is not suitable for Region 1 and that Region-3 should consider 144.800
• To consider an additional 144 MHz frequency (that might be compatible) with Region 2 and 3
• To also consider 435 MHz usage and newer APRS technologies (for the 2017 GC)
