My 15(?) year old yaesu ht is half the size of my current smart phone. One of my ham friends has one a lot smaller than mine...


But the point is moot if the OP didn't realize he'd need a licence and all that and is unwilling. Size might not even be a big concern, I was just throwing it out there. And for the record I have no idea how much ham activity is in Central America, what bands they use, I haven't really been into the hobby since my college days.
