[amsat-bb] QRM on AO-51

Hi alls, Here in Japan, I can hear many mixed voices, other than amateur radio traffics via the bird. It sounds like from cordless telephones, used in Chinese speaking area. And some time Japanse, but non amateur, too.

To reduce QRMs on AO-51 caused by turning transmitter on by non-amatuer traffic, I strongly feel the ncessity of PL tone to reactivate the bird's transmitter.
