Are these radios capable of tone scan?
Scanning for CTCSS Tone
1. Press the [MENU] key to enter the menu.
2. Enter  on your numeric keypad to come to Menu 11: R-CTCS
3. Press the [MENU] key to select. Insure you have a tone activated (and it is not off)
4.Press the [*SCAN]to begin CTCSS scanning
A flashing "CT" will be in the left status display to indicate the radio is in CTCSS scanning mode.
In this mode, whenever the radio is receiving an RF signal on the selected MR channel or VFO frequency,
the lower display will cycle through the CTCSS tones as they are being tested. Once the frequency of the received CTCSS tone is determined, the "CT" indicator will stop flashing.
Press the [MENU] key to save the scanned tone into memory then press the key to exit the menu.
We have one and ordered another last night for our grandson.
I am very pleased with this radio.
