Way down in the specs you have the sampling rate, 122 MHz and I don't see a spec for the A/D Equivalent Number Of Bits (ENOB). That is a useful measure of the dynamic range, as most if not all 16 Bit A/Ds have a lower number of ENOB. Perhaps these should be more prominently advertised as they can be used to compare direct sampling SDRs in a more Apples to Apples fashion.
Do you use an FPGA as a Digital Down Converter? If so, prominently advertise that too. Having a high bandwidth I/Q output to USB or Ethernet, and a driver to the standards used by multiple Panadapter and Spectrum Analysis software would also be great. Lastly, the ability to directly sync to a low phase noise 10 MHz reference without frequency jumps would be very useful with said Spectrum Analyis software to be able to use the K4 as a measuring tool. Maybe two modes, sort of follow a crappy 10 MHz source and lock to one that has low enough phase noise to match your radio's performance. 73, Mark W7MLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
