RE: Frequency control?
Guys,
Frank initially said he was going to issue a pin for 2.4 GHz at FL Jets, but decided in the end not to require any pins for 2.4 GHz. It hasn't been a major problem - mainly due to the fact that the winds were so bad today that nobody wanted to fly (and only a few did).
John Redman flew the snot out of his KingCat with a Spektrum module in his JR 10X and another JR rep flew a CARF Flash with a DX-7. He went WAY out there, and there were never any problems with either aircraft. BV also flew his new Electra jet on a DX-7.
I don't think that the Spektrum 2.4 GHz radios are going to be a problem at the smaller events, or even at the bigger ones, until more folks get them. Also, I think its still unclear how the various manufacturer's 2.4 GHz systems are going to play together.
One of the interesting tests will be at the Joe Nall flyin (> 500 pilots) when 100 or more of those systems show up. It appears that only a maximum of 40 can transmit at a time, and what will happen when 40 guys have their radios on in the pits or the ready-line and a guy steps up to fly and his Spektrum TX won't radiate because it can't find 2 open "channels" amongst the 80 that Spektrum has divided the band up into.
Frank, for this year's MidAtlantic, I would recommend allowing Spektrum DX-7 or module flyers to fly, and NOT impound their transmitter. I would simply keep a list of pilots (and the corresponding aircraft), that are flying on 2.4, just so that everybody knows who they are. Frankly, this year, I'd be surprised if more than a dozen Spektrum systems show up.
