R: Be prepared for the worse



Hi Fred, W0FMS

You cannot operate EME at 2.4 GHz for the simple reason that in IARU
Region 1-2 and 3 the 2400.000 to 2450.000 MHz band is allowed for
Amateur Satellite Service.

In IARU Region 1 band plan only ATV is permitted between 2427.000 to
2443.000 MHz if no satellites uses this segment.

If  you start to use EME at 2.4 GHz against the IARU recommendations for the
simple reason that already you have some receiving equipments for AO40 than
the life for Satellite Service will be worse in the future,more worse than
actually considering all existing pollution owing for LAN, cordless and so
on.

Contact please your VHF/UHF/SHF Manager IARU Region 2
