Maybe the way it's presented.
Probably.
A better word could be Scenario plan. Different setups of FL's that can be saved and quickly fetched. It's almost exactly as the Profile settings in Sentinel but works directly on the scanner and only involves the FL's in the same way that the startup keys are doing, and in some way as virtual scanners in Whistler scanners.
If there is some hidden remote command in Unidens scanners that can trigger the power on startup keys, besides FQK, SQK, DQK there would be a PQK, then that function are exactly what would be used, a quick way of fetching preset selection of FL's. A startup key like 1 can now be set to enable FL 1-2-3 and startup 2 to FL 4-5-6 and startup 3 can be FL 3-4 as one FL can be assigned to several startup keys.
The remote command to select FL's has to include all 00-99 quick keys and their state for each can be set to enable-disable-ignore and that whole string of FQK,2,1,0,0,2,..........,0 could be saved to a menu selection as well as a Windows keyboard hotkey configuration, if ProScan can make use of it. Each different configuration of a FQK string can be saved to its own location, SP1, SP2 and so on.
If that would be possible to implement then additional functions can be done that triggers those SP stored settings.
For that special REV function, if one scanner controlled by ProScan can be set as a slave to another scanner, then that other scanner are set as master and configured to use that first scanner as slave, then master are sending the active frequency, the one displayed in the log, to the slave and the slave then do REV on that frequency and temporarily interrupts whatever it is doing. When master continues to scan or duration timer stops, the slave would preferable go back to prior duty, being it scan, search or any other mode it was set to.
The special REV function could be enabled by a menu like in Options or Tools and then a button would appear, perhaps like the ones "Active Row In View" or next to "Audio Control" with a "REV Monitor" label to quickly enable or disable the function.
