I use to have a reference to frequencies used by the different cell systems. That's my call .. and I can't think of another industry that just like the Thunderbolts that when it does a refresh or a fix from a design oh-shit dumps so many of the same thing.
I just read US Patent 6,282,184 "Common Digitizing Rate for Multiple Air Interfaces for Generic Cell Sites in Cellular Radio" .. it mentions it.as a base frequency (11.37) -pete On Wed, Dec 14, 2011 at 2:44 PM, Azelio Boriani <[email protected]> wrote: > The 63.8976MHz frequency seems to be related to the OFDM frame of the WiMAX > standard that has a window of 62400 bytes and the 63.8976MHz can time WiMAX > BaseStations with only powers-of-2 dividers. > > On Wed, Dec 14, 2011 at 11:24 PM, paul swed <[email protected]> wrote: > >> Could be but as a timenut not real magical to me either. >> Regards >> Paul >> >> On Wed, Dec 14, 2011 at 5:06 PM, Javier Herrero <[email protected] >> >wrote: >> >> > I'm begin getting curious... having already received that OCXO, and with >> a >> > 2nd unit arriving...
