In a world of digital comms with very capable competition, AOR has been looking for a reason to exist. They have turned to high end gear. For some time now, their radios were DDS and capable of running from an external 10MHz. I suspect they are used in a rack of gear to direction find. The black box SDR version is the next obvious step since nobody was actually playing with the knobs anyway.
I would be surprised if there were vans with 3 or 4 of these black box radios as part of a "stingray" or "silent ping" set up using correlation techniques to RDF cellular users. It has enough bandwidth to cover all known cellular providers. It could probably RDF wifi. -----Original Message----- From: Jim Lux <jim...@earthlink.net> Sender: time-nuts-boun...@febo.com Date: Wed, 24 Apr 2013 04:33:26 To: <time-nuts@febo.com> Reply-To: Discussion of precise time and frequency measurement <time-nuts@febo.com> Subject: Re: [time-nuts] Radio with GPSDO On 4/23/13 6:54 PM, li...@lazygranch.com wrote: > http://www.aorusa.com/receivers/ar2300.html > > Just a FYI. > Interesting.. I see they use the OEM GPS from Garmin. I wonder what kind of DO performance they get, and whether they actually discipline the oscillator or just measure it. Since they've got a DDS, they could use a quiet fixed OCXO, undisciplined, and just adjust the DDS control word. Fascinating, also, that they provide a raw I/Q sample output. Clearly, that's the way of the future, and it makes sense. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
