No, when the beacon's off, so's the digi.

You must have the volume turned down, your receiver front end is dead,
or your antenna's not plugged in, or all three..

 Gilb's Laws of Unreliability
1. At the source of every error which is blamed on the computer you will
   find at least two human errors, including the error blaming it on the
2. Any system which depends on human reliability is unreliable.
3. Undetectable errors are infinite in variety, in contrast to detectable
   errors, which by definition are limited.
4. Investment in reliability will increase until it exceeds the probable
   cost of errors or until someone insists on getting some useful work done.
