Re: Re:13 Amateur Satellites to Launch in June



Hi William, PE1RAH

I agree completely with you !

They are not amateur communication satellites they are only satellites
using the spectrum recommended by IARU band plan for the Satellite
Amateur Service

The last "real" amateur communication satellite made for the Satellite
Amateur Service i.e. for all of us "to communicate" was VO-52 built
by indian people with your cooperation................go ahead !
