silly general question

Hello, I was gifted two Midland GTX400 radio’s, as was my father. My two radios communicate fine as do his, but I can’t get all four to talk to eachother. I know this sounds silly but why won’t they all work together? I have been very careful to set them all on the same chanel with the same privacy settings, but they still don’t work. Any help someone can offer would be great.

The only things that I can think of that would cause what you are describing is the radios being on a different channel/privacy code, or the radios being out of range of each other.

Are you absolutely certain that you have matching channels/privacy codes? If so, try turning the privacy codes off and see what happens.

Here is the Midland GXT400 manual, if you need it.
