No, wait, what???  You have the same problem with a tuner make by a different manufacturer?   It is time to start looking for items that are in your system no matter which tuner or antenna you are using.  Don't ignore the radio side of the tuner.  An intermittent short or open in a connector or coax on the INPUT side of the tuner will cause the tuner to be unable to figure out what frequency you are on since it can generate square waves with harmonics well above HF.  Look for items that are common no matter which tuner you are using, and don't forget the radio itself.
