Hello, hope you can help, I sent my FT-450D to a good friend in Florida as he just got his General license. but the radio is not transmitting when he presses the PTT button on the microphone, I sent him a brand new one and the same, everything else works on the rig, the tuner works, the up and down frequency buttons on the microphone works, he has reset the radio a couple of times, but no luck so far on the PTT button. I know it is probably a setup issue but so far we have not been able to find the right one to unlock this mistery.

What microphone is being used with it? I quickly Googled the title of this thread and found the following video. There is a lot of mundane blah blah blah but it addresses a safety issue of the FT-450. The TX is inhibited if the radio is turned on in TX mode.
