I just bought a pro-97 and is there a way when it is stuck on a specific frequency to see the group number instead of showing the tone? How do i make the backlight come one only when there is a transmission?
If it's showing a "tone" (I'll presume that means a CTCSS tone frequency), there's no "group number" to display. What are you interested in seeing?
No, the PRO-97 - like all other GRE scanners - has no provision for lighting the backlight based on open squelch. (GRE's PSR-500 family will let you set an "alert" for each "object", which can include backlight functions, but that's utterly different.)
If you're referring to the PRO-97's "Bank Alpha/Text Tag"... no, there's no way to display that when displaying the CTCSS/DCS information for a conventional channel programmed to show CTCSS/DCS information. The only way to display the bank's alpha tag is to leave the channel set as "FM" - with no CTCSS or DCS setting.
While this is true on the earlier scanners (PRO-92, etc), it is NOT true for the PRO-97. If you have a channel set to FM, the 4th line is blank. The only time you see the bank alpha tag is while it is scanning.
This was the first issue I encountered with the PRO-97. I love the fact that the bank alpha tag shows all the time on the PRO-93/PRO-95 and in FM mode on the PRO-92. It was a step backward to not provide this on the PRO-97.
