396XT Fire Tone Out
No, you cannot do that. Although I never had a 396T, I think they are similar in that the memory allows for 10 different frequencies/tone pairs to be stored. The 396XT added the Fire Tone Out Search functionality. When in Tone-Out Standby it will simultaneously decode up to 10 sets of tones, if they are one the same frequency. If you have say 154.190 programmed with 5 sets of tones and 154.445 programmed with 5 sets of tones, if you select Fire Tone Out Standby and select 154.445, it will decode any of the 5 sets of tones programmed for 154.445. There has even been discussion in other forums regarding Motorola Minitors that scan having the ability to Tone Out on dual frequencies, but inherent problem is when it switched from one frequency to another it might miss the tone being sent, so it probably would end up being hot or miss. Unfortunately, that pretty much means that it requires a dedicated receiver for each frequency that you want to monitor.
