I know the use of Roger Beeps isn't the usual current practice for Radio
Amateurs, at least in IARU Region 1, so it maybe that it's unlicenced operation
such as extended range wireless phones etc. There seem to be a number of those
in use in the northern part of the Russian Federation.
Reports of interference in Amateur Primary allocations (2m, 10m, 15m) clearly
need to be co-ordinated. Can somebody comment on the correct channels (email
address) to pass reports of this nature to ?
Instances like this show why it is important that, where power considerations
permit, Amateur Satellites do not use CTCSS tones for access, since we need to
know what interference is occuring in various parts of the world.
