I had originally bought a set of BaoFeng BF-888s+ radios that perform very well and perfectly suit my needs.
Needing more, I bought another set, this time buying BaoFeng BF-888s radios.
(Same model code, except the "+" at the end, apparently just a restyling).
The new radios don't talk to the old radios, despite being on the same channel. Both radio sets work well among themselves, but the two sets don't communicate with each other.
I bought both sets from Amazon, delivered to a US address. I live in a country where regulation is not an issue (not the US).
How can I make both sets talk to each other?
I've read somewhere that these BaoFeng radios have a programming cable (that I don't have). If these radios can actually talk to each other, I would very much prefer to fix them without using a cable (e.g., using keys on the units in a way that allows configuring them), as I don't have one, and getting one would be both expensive and time consuming considering where I am now. Otherwise, if getting a cable is the only option, is this a standard cable that can be bought in computers/electronics shops? Is their software readily available?
