    Thanks for the fast reply.  I am powering the station with solar, seven 240 watt 48 volt panels charging seven marine batteries in 12 volt, parallel.  It just started a couple of hours ago and I have not had much time to fully check it out.  Tomorrow I will check power cables and connections, voltage and such.  Also check the codes.  I have used the radio since it arrived in June with no problems.  I was hospitalized twice right after getting it and that delayed setting it up properly by reading the manual and setting the features I want.  I hope to complete that soon.  I'll repost here with what I find out tomorrow, hopefully having found the problem.

     Again, thanks!

     Jim, sometimes the power pole connections on the back of the radio come loose a bit, check that. Make sure its in all the way, you could have an insufficient ground because of it. Good luck brother. Stay out of the hospital. God bless.

    PROBLEM SOLVED!!  Thanks folks, all that was wrong was the power connecter where it hooked to an old MFJ power distribution unit.  I simply installed Anderson Power Pole connectors and plugged into my new MFJ **** which solved the problem.  Thanks again!
