The pair are programmed on the three 449Mhz channels ie 449.3125,449.400,449.475 with Ctcss tones of 156.7hz, 165.5 and 192.8 respectively. They are working fine and they have good batteries. These radios are intended for professional use and you are supposed to get a £75 licence which is valid for 5years. If you are interested in three radios I do have another one brand new in the box which could be sent with the same frequencies as the pair. Obviously a little more expensive as it is brand new with a battery. An additional charger could also be supplied. Message to discuss if interested in the three.
