The frequency resolution (or step) on FIA's manpack radio RF-10 is still 0.5 MHz, whilst since 1.5/1.6 all group frequencies are now spaced at 0.2 MHz intervals, making it impossible to access most channels.

Also, RF-10 radio's default channel is still 48 MHz while the other FIA radio (R-148E) has 42 MHz as default platoon channel (though FIA's faction set up has 52MHz as platoon channel)
