Subject: 2400 MHz NB segment to protect geostationary Amateur Satellite service
(ESHailSat2)
Committee(s): C5
Summary: Currently our 2400 MHz band plan does also recommend to use 2,400-
2402 MHz for narrow band contesting in countries that do not have access to a lower
segment in the 2,320 MHz DX segment. To avoid interference we think the
conference should reconsider this standing recommendation in the VHF handbook.
Introduction
In December 2018 the first geostationary Amateur Radio Satellite has been launched successfully.
Background
The EsHailSat2 will be geostationary overlooking ITU Region1 with transponders to offer
communication for a large community of radio amateurs. This will include a narrow band uplink
frequency in the 2,4 GHz range and downlink in the 10,490 MHz segment.
Key points and proposal
Since the geostationary orbit of this new satellite will attract many new users, it is also to expect many
more transverter kits for CW/SSB to be around that cover 2400MHz with significant power. Currently
our band plan does also recommend to use 2,400-2402MHz for narrow band contesting in countries
that do not have access to a lower segment in the 2,320MHz DX segment. To avoid interference we
think the conference should reconsider this standing recommendation in the VHF handbook.
Recommendation:
We therefore propose to change the narrow band DX segment to start from 2401MHz to avoid
interference, but still benefit from the increased activity on this band.
