Conference Watch
The RSGB Working for You
First, an apology. Owing to a breakdown in
communications, we were unable to bring you the
promised detailed daily bulletins from Tel Aviv
last week. The following is a report on the week's
proceedings:
It's been a busy week at the IARU Region 1
Conference in Tel Aviv, Israel. A full report is
being prepared for RadCom but as everyone will be
wanting to know what changes are coming as soon as
possible here are the headlines from the RSGB
Delegation.
50MHz
The RSGB request for alternative repeater outputs
below 51MHz was approved. This should help ease
the path to a 50MHz repeater network in the UK.
144MHz
The 144-145MHz sub-band has been replanned to give
a properly defined digital sub-band. The new plan
is:
* 144.000 - 144.035: EME Exclusive
* 144.035 - 144.150: CW
* 144.150 - 144.400: CW & SSB
* 144.400-144.500: Beacons
* 144.500 - 144.800: All modes
* 144.800-144.990 Digital communications
There will be a phased changeover to this plan
during 1997.
Repeaters
FM channel spacing: There will be a phased
changeover to 12.5kHz channel spacing for 145MHz
FM. This will start with the repeaters early next
year.
The use of CTCSS instead of, or as well as,
1750kHz tone is encouraged.
Channel Naming - with the change to 12.5kHz
channel spacing. The old S and R channel naming
doesn't work and a new scheme has been devised.
Full details will be published in RadCom as soon
as possible.
Beacons
A project is being set up to establish high power
144MHz beacons on each side of the Atlantic to
investigate transatlantic QSO possibilities.
Other Headlines
* Ideas for wideband data experiments on the
432MHz (eg for digital ATV) received
recognition.
* 3.4GHz and up EME polarisation - the standard
as been changed to linear from circular.
* The SSB 'centre of activity' on 50MHz has
been moved to 50.150MHz.
* Frequencies in the 144MHz band for SAREX
(Shuttle Amateur Radio Experiments) and the
future ISS (International Space Station).
* New guidelines for co-ordinating 29MHz
repeaters.
* Packet frequencies in the 14MHz band have
been clarified.
* Satellite frequencies on 29MHz have been
changed to 29.300 to 29.510MHz.
* IARU Region I policy on packet/Internet
interconnections clarified.
* Project to obtain new common LF band
allocation.
