[Premium-Rx] RFSpace SDR-14 digital receiver

[Guy Atkins]

Keep in mind that the SDR-14 is more of a lab instrument, rather than
strictly a receiver. It will be lacking in certain performance specs that we
take for granted in a premium or "serious" consumer-grade receiver, for that
matter. From the rfspace.com web site:

"A secondary application of the SDR-14 is as a general coverage receiver. It
can perform as a respectable receiver but since it has a "wide open" 30MHz
wide front end, it can be overloaded by any strong signals within the 30MHz
band. The SDR-14 has built in attenuators that can be controlled from the PC
to help as well as a manual jumpered broadcast band HF filter if one is near
a local AM broadcast band transmitter. Any demodulation functions must be
done by the host PC since the SDR-14 does not have any DSP functionality to
perform demodulation."

For other options in a software-defined receiver, check out the g303i or the
newer g313i from Winradio http://www.winradio.com/home/g313i.htm or the
SDR-1000  from Flex Radio: http://www.flex-radio.com/   The g313i also does
RF spectrum recording to hard drive like the SDR-14, but only in 20 kHz
swaths of RF. The SDR-14 apparently will record a 160 kHz wide bandwidth of
RF for later playback.

I'm in lust.

How much?
