The first 955 I bought without a crystal cause I have many new cyrstals here on my channel. I've never not once had a problem buying a receiver and putting my crystal in it (until now). It just occured to me the other night that it could be I simply have a 940 receivcer that's not perfect and a new 955 that's just not perfect. Interesting that both the high end receivers and the two or three low end receivers I have would all work close up, albeit with a few jitters on the non-pcm receivers. But all would fail miserably walking 20 feet from the airplane.

Lee, I'll go 100 paces this evening, I went 75 and I'm in a neighborhood, wasn't much further I could go and still see my Fiance to give me the hand signal if the speed brake popped up in fail safe. At 75 paces I did turn the switch off to make sure it would go in fail safe and it did. I turned back on and danced in circles all the way back to the airplane in pure control and happiness

So, at least for me the lesson learned order my JR receivers "with" a crystal in them. I had heard that before, but my practical experiance suggested that swapping cyrstals was not a range issue. at least till now.
