This feature would be a lot more useful to me if you could either have it listen for multiple sets of tones on multiple frequencies, OR listen for any tones on multiple frequencies. Reason is, the fire departments here use a number of different tones (for each station, region, zone, etc) on multiple frequencies. Setup a tone-out bank where you plug in your frequencies (all of them), and either plug in your sets of tones or tell it to alert on any tones received, and it just sits there and scans through the frequencies. Ah well...
