This happened a month ago and then went away. Now it's coming on more
regular. Usually I remove the power and when turned back on, it's gone.
Today I have put it off and on 6/7 times and it still remains. Checked all
the PTT connections etc and OK. Even removed the PTT mike. No key
attached. Ideas?
