Re: AO-7 report.- Band switching



Hi John...

Thank you for answering my questions, I now have an understanding of your
basis for believing that the timer no longer functions or is random at best.

I am now willing to wait quietly for the Eclipse-free date. Has it been
estimated or calculated?

Many thanks!

Roger
