But how do they know which repeater to call you on?
That's why the D710 can put ur voice freq in ur packet.

That's a bug that should get fixed in the next firmware.

The difference in communications area between a voice repeater
and simplex Voice Alert is from 10 to 100 times greater.  So it
makes a big difference in your voice reachability...

That is not the cause.  The cause is simply a bug in the
scanning program.  It stops scanning because the radio
transmits.  It will do this whether you have the auto-frequency
update enabled or not.  But I agree, It should not stop scanning
side B if side A transmits.

Hopefully they can fix this in the next release.
