[NSRCA-discussion] Digital Pug-In module

[Jay Marshall]

Check some of the signal views posted on the 'net using a spectrum analyzer.
You will clearly see the difference.

I don't know what you mean by "pure spread spectrum" -- Futaba uses the
frequency-hopping style of spread spectrum, while JR/Spektrum use the
direct-sequencing style.  Both are internationally-recognized types of SS --
there is a third (which I can't remember at the moment) and  several hybrid
types.  All must meet global standards for SS transmission.

The technology is different. Futaba is pure spread spectrum and Spektrum is
dual frequency diversity. Probably isn't any difference to the non-engineer
and both work very well. A slight advantage to the Spektrum is the number of
Bind-And-Fly models that Horizon is putting out.

I have a Futaba 9C currently on 72 MHZ. I see that both Futaba and Spektrum
have conversion packages for 2.4 access. Any comments on either or both?
(Spektrum is offering a good price right now!) Thanx-- Larry
