Each receiver features two separate receivers and antennas built into one device. The transmitter transmits on two frequencies simultaneously while the receiver receives and decodes both sets of information. Should one signal be blocked or corrupted or should one receiver malfunction in flight, the other frequency or receiver will take over. DuaLink offers the security of having two radios operating simultaneously on two separate frequencies. This is called dual path redundancy.<BR><BR>Steven Maxwell<BR> <BR> <BR><BR><BR>> [Original Message]<BR>> From: John Konneker <jlkonn@hotmail.com><BR>> To: <nsrca-discussion@lists.nsrca.org><BR>> Date: 2/26/2007 10:59:24 AM<BR>> Subject: [NSRCA-discussion] 2.4ghz<BR>><BR>> I have been teetering back and forth over buying one of the new DX7's.<BR>> There has been a lot said about the "can't" be interfered with in the 2.4ghz <BR>> band.<BR>> Someone posted this link on one of the RCU threads.<BR>> http://www.fcc.gov/Bureaus/Engineering_Technology/Documents/cfr/1998/47cfr15.pdf<BR>> Specifically section 15.247 looks as though it says a channel hoping system <BR>> can occupy any channel for up to .4 seconds.<BR>> Although the data to the rx may be unique wouldn't this still cause a <BR>> lockout due to the bad "packet" being received?<BR>> Does this mean it would be possible for several FASST channel hoping systems <BR>> to cause a noticeable problem on a system such as Specktrum's that locks on <BR>> to a single channel when turned on and stays there?<BR>> And I guess to some extent to other channel hoping systems?<BR>> I am no expert...<BR>> Just trying to understand this sea change about to occur with our radios.<BR>> Thanks!<BR>>
