The an prc 77 and 1077 used rechargables when i was in ,one plugged in and a spare in the batteri compartment .Reloading had to be done by a cord in the NM-135 / M113 variant we used.

It gave app 5 km range in good conditions but could do better if lucky .

Foliage ,terrain,buildings ,weather would easily cut range in 2 or 4 .

The An-Prc whats its name handheld 2,5 km radio was strictly LOS in many cases.Sometimes it would do better if lucky ,but I recall talking with the guys who used them a lot and they said to make sure of contact you would have to be abl eto see the other guy !

Old version this .

Couldnt say about more modern stuff.The AN pRC 77 we had in our IFVs using long whip antennas and vehicle powersource I guess could do 20 km or more if lucky .

All American made stuff.

Tried Motorola handsets later got a good 2 km out of them if not to much obstacles ,but this dropped with above mentioned conditions .Used a civvie VHF radio in our APC too ,got a good 20-30 km out of it -more if lucky .

Sometimes radios sound crystal and sometimes like mush even if the weather is the same and the radio location too.

Go figure.
