Default RE: Spektrum DSMX


ORIGINAL: Kimhoff

Horizon Hobby sticks it to the modelers again. They are not offering DSMX for the modules that fit the 72 Mhz radios, unbelievable!



Iam happy the Chinese have quality modules that work so I can get rid of my Spektrum DSM junk and put a quality module in my exisitng radios.

Too bad Horizon didn't figure this out so they could keep their customers they ripped off.



Kimhoff and all readers,

The 72 Mhz band is not suitable for frequency hopping like it is possible in the 2.4 Ghz band.

The 72 Mhz band has 72.010 Mhz to 72.990 Mhz a spread of 0.98 Mhz. ( 980 Khz ) divided in 50 channels of 20 Khz each. In reality it is 1000 Khz since the freq mentioned are the center frequency of the channels.



See _ _ _ http://en.wikipedia.org/wiki/Electro...nce_at_2.4_GHz



The 2.4 Ghz band has 2.400 Ghz to 2.500 Ghz . A full tenth of a Gigahertz or 100 Mhz. A lot more space to hop around.
