Where/how exactly did you install the chokes on both the shore power line and the coax (I assume the external TV connection)?
I am going to try the situation with the shore power at the next park along our route and see if it makes any difference. I will also contact technical support for both Concertone and for the converter to see if anyone has anything to say.
Yes, the one on the coax it the one that runs from the antenna to the radio. Go to Radio Shack & ask for suppressors & or chokes. The are made to open up & form around the power wire & coax. To me the inside material looks like it is carbon like you see in lead pencils.
I don't have the parts numbers however if you look at my profile & go to my statistic's then look for post started by Emptypockets if you go back far enough you will see where I posted a full report on what I did.
