4-4-5 VFO FREE search

The VFO FREE search parameter determines how long the AR8600 will remain on an active frequency

before resuming VFO search even though the frequency is still active. This is useful if you wish to gain

a picture of what is happening on a band without the AR8600 being tied to a busy frequency for long

periods of time (such as when monitoring active amateur band repeaters etc). VFO FREE search saves

you having to manually intervene to force the VFO search process to resume and saves the need to

lockout frequencies using the FREQUENCY PASS facility. The limits are OFF and 01 to 60 seconds
