A great feature about the newer Icom handhelds is that they are programmable from a computer. Especially nice for the Q7a and R2 since there is no keypad. Even on the W32a it can get tedious to program a great number of channels. The software from RT Systems makes it quick and easy. Buy the cable and software for one radio and just the software for the rest.
Same cable works for all handhelds.
You just need the special adapter for the Q7a unless you own the speaker mic adapter from Icom.
