[TowerTalk] Big Rak and HDX-555

[Les Kalmus]

No one is calling anyone anything.

My experience is what I explained with a heavily loaded Orion AND a 
lightly loaded second Orion (but no slippage) with both using the stock 
controller with the updated electronics. In fact, one of those 
controllers was so noisy that M2 sent me an RF filter kit which helped 
but didn't eliminate the problem. I have the photos to prove it.

Green Heron controllers fixed both problems.
