I play airsoft here in Quebec Canada, and I have 2 Baofeng BF-888s that I got a few years back. Now people are mostly using UV-5Rs. I used CHIRP to program my radio to the same frequency used by the field so that everyone can talk but even with the right frequency something is wrong. On some channels I can talk but I can't hear on any of the channels. I guess it's something else that is different but I can't seem to find what.
The channel that are used are 1 to 5, the others are the default ones from the factory that I don't use, I only needed 5 channels.
