Dear Henry R.,

If it isn't the path (although it was at one time, it seems), and it  
isn't the RX (stable with dipole nearby the TX), and it isn't the TX,  
what else haven't you substituted or virtually swapped/moved? For my  
money, substitution is THE BEST method for getting close to or pinning  
down what it is... At least that's what I'm used to in the real world.

There are prizes and surprises all the time, though.

Do you have a way to measure return loss at the main receive antenna?  
Can you sweep it in place? Either might give a clue.

Regards,

Henry
