[NSRCA-discussion] 2.4Ghz

[John Konneker]

Thanks Allan,
I talked to Horizon yesterday and they suggested I swap receivers since I had a spare.
Range tested and all that good stuff before flying.  First flight was about like most of the others but second flight was
much improved.  Had to head for home after that but I'll try it again today I hope.

I flew my pattern ship all last year using a DX7 and the AR7000 with no problems. Later I bought the flight log and tested it on the AR7000. While it showed correctly there were two receivers in operation, some of the other readings were strange. It turned out my AR7000 wasn't upgraded to support the flight log. Still the flight log acted as if it did.Recently I bought a R921 on e-Bay. I range tested it with the flight log. The readings were terrible. I sent the R921 back to Horizon. They could find nothing wrong. When it returned I tested it again. Still bad readings. Talked to Horizon again. Was told to try it in a plane. Before doing that, one more time I range tested it on top of a paper box. Did the exact same thing with two receivers that I had successfully test flow in an airplane. This last test, the "bad" receiver had better numbers than the two "good" ones!I'm now wondering if these receivers retain some information after being turned off and this leads to erratic flight log readings. BTW, someone on one of the discussion lists says when there is a frame lost it is not counted as an antenna fade. I don't know if this is true but it does make the math work. Yes, I've had on occasion more frame losses than antenna fades.AllanIn a message dated 6/25/2008 9:20:15 AM Central Daylight Time, jlkonn at hotmail.com writes:
I am curious what other folk's experience has been with JR/Spektrum 2.4Ghz.I have experienced a frame loss when one satelite Rx showed -0- fades.  It's my understanding this shouldn't happen.  I have another 9ch Rx from the "Great Receiver Giveaway" I'm going to try but was wondering what others are finding is average for fades and frame losses per flight?Thanks!JLK**************Gas prices getting you down?
