Sorry for your loss, I have a Wills hobbies 73 inch Zero.  I think it is quite close to the CMP.

 In you video, what was the beeping I kept hearing? And in the back ground I do see a tower of some kind. Any chances you were getting interferance from the tower?

 It looks like there are microwave dishes and cell dishes, are there any new dishes that have gone up lately? maybe running close to your frequency or drowning out your TX...

BTW beautiful land scape. Love to get my dirt bike out there for a rip or two.
