The continual tone is more than likely the spot button next to the speed 
control for CW keyer. Make sure that the button is not pushed in. It is real 
easy to do. I have done it a few times.

There is a relay inside the radio. If you are hearing it chatter. you should 
see the radio going from TX to RX.If you do not see that, not sure. There 
could be some thing else. I have not gotten into the digital modes yet, some 
thing that I will more than likely do eventually.

When I get frustrated with the radio here is what I do....
Unplug every thing from the radio. Add just the power & coax. Go through it 
all and make sure that things are normal. 90% of the time there is some 
thing. Add the CAT interface for computer control. Then I check the audio 
connections, one at a time. Also make sure that you are using the proper 
connector to the proper jack. I always forget which are stereo and what are 

Hope that helps!
