Re: re: Crying wolf? RS-15



The received signal strength was as stronger than I normally hear the
beacon (when I can hear it), but it I've hear the beacon as strong as
the return I was getting.  As I noted, I did not hear the beacon.

I'll try again tonight.  I'm usually up late for the FO-29 passes.
