The IARU Region 1Â*Interim Meeting was heldÂ*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 a

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 extendedÂ*[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)
