Well, on 80 meters you probably need more than a short counterpoise, and you do not mention how long the random wire is.? A tuner can load up all kinds of poor antennas and just results in RF trying to go someplace it shouldn't.? I understand the antenna dilemma if you are dealing with restrictions.? But if you want your QCX to work then you will need to reconsider that antenna system...
