Will it go into transmit if you press the mox button? ?Will it go into transmit when you hit the Morse key?

Hi !

You can find all information in manual section here :
/g/Yaesu-FT-980/files/03%20-%20Yaesu%20FT-980%20All%20Manuals/FT-980%20Operating%20Manual
The MOX button acts as microphone PTT, it can lock the FT-980 in transmit mode until depressed.
Very usful to send? a tune by selecting FSK mode.

jean have you ever repaired this radio for no transmit? i am thinking that maybe something is bad in the power supply of the radio and i wanted to know if i can use an external power supply for a ft-107m and see if i can get the ft-980 to transmit? marc

Before you attempt to use external supplies you should measure the voltages of the internal supplies.

Is it set to a ham frequency?

Why not download the manual and learn what controls are available?? and then what the theory of operation is?.

There is so much of this buying broken rigs and then getting on line to see if someone can tell you what to repair.

In it's day the FT-980 was Yaesu's top of the line radio.? This hobby will become much more rewarding for you if you can develop basic troubleshooting skills and solve a lot of these problems on your own.

For us old farts.....there were no computers or internet, just snail mail or the telephone.? ???

Is the radio connected to a dummy load or suitable HF antenna? Power it on, chose a ham band and post some photos of the front panel so we can see the frequency and positions of all the knobs etc

As Wald posted....

--Just to eliminate the cockpit errors... you are in HAM mode, right?? Not GEN???
?
You probably do not realize how many times I tried to call someone while in GEN mode...?
So please confirm and we will move forward.
