All my radios use RT Systems' software and it is
simply the best out there. If you have 2 or more radios you can "Copy & Paste" entire Simplex/Repeater files from one radio to another in seconds to reprogram the other easily. The programming cables always work (unlike cheap offshore ones) and simply you will never go wrong. Always remember to save the original download Image File from your radio and save it as such. If your radio ever acts up you will need this File to reset the radio. Then start with your Programming and save that File as you wish to name it.
