When this radio is not in crossband repeat mode it will transmit by itself. The transmission lasts about a half second.
Has anyone else noticed this?

Yeasu used to have a function in their HTs and mobiles called Auto Range  System.

If you had DCS operation selected and ARTS turned on, the radio will transmit a 1-second DCS burst to see if any other radio with DCS and ARTS turned on was in range. It would do this every time the PTT was pressed or bout every 15 seconds. If another radio was in range, it responded and your radio would ring bell.

Perhaps you have this turned on.

Check your owners manual for the ARTS system.

I guess this should teach me to read the manual. I do appreciate everyone's help.

Was having ARTS turned on the problem?

Does not appear to be the problem.
This particular radio has manafested some other problems as well. The cure has been to turn it off and back on.
Once it had very low audio on xmit. Turned it off and back on and the problem was cured. Same thing on this momentary xmit problem.
Thanks for the help.

I think it's time to send it to Yaesu.

BTW, have you done a RESET, according to the manual?

Sometimes a reset will solve a multitude of problems.

Also, has it been modified for out of band operation? That can also, if not properly done, cause strange things to happen.

Not yet. But I am going to do that next.
There have not been any mods made.
