as much as people badtalk those frs radios, I had a pair of motorolas that worked as advertised as far as I could tell... definitely better than 500m range.
Having a radio is better than not having a radio. Then you get into the BS that was NF2... where nothing cut through the channels because there was so much going on.
as a matter of fact, I think my motorola talkabout worked more than the woxoun I have now. Alas... both of them are sitting in FRMSC's lost and found at the moment. :P
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
