Review on SURECOM SF401 Plus: Advanced Frequency Counter with CTCCSS/DCS Decoder for Radio Transceiver by Puggzy Wallin

Now I can use my radio for work. That way I know it's clean, loaded, and working properly. Used the finder to get the frequency and ctoss numbers. They said that this is a hidden channel and cannot be shared. Now handy for stealing frequencies from baddies at local airsoft games. All you have to do is create a list of channels or figure out how to tune in to the radio instantly.
