1) if you're talking AM radios.. any TX works with any RX as long
as they are both on the same band with the correct pair of xtals.
With FM you've got issues with single vs double conversions,
and hassles with incompatible xtals at times.
2) yes you can use RXes with more channels than your TX;
also viceversa. Still have ch1 & ch2, the rest just do nothing.

also depends on the transmitter as the KO ex-1 mars r will only work with the kr301f i think.
where as the ex-10 helios will work with any rx
Helios has a switch you can flick to "old compatability" mode to
work with non-HRS gear. If you don't then it won't work.
Mars-R don't have this switch.
