Is the console unit on, and does it have a wide angle transducer? I could see interference happening in this case. Does the interference go away if you turn off the console unit?

Not familiar with the newer HBird units(yet), and the interference between two of them, or the lack thereof.

Do you have that unit powered from one of the TM batteries. If so, that is the problem. Power it from the starting battery.
