[Elecraft] K3: pseudo KRX3 "free" via LP-Pan+Power SDR

[Eric Swartz - WA6HHQ, Elecraft]

Yes. Actually only withing the bandwidth of the sound card, which is 
much less than the K3's IF bandwidth pre-crystal filter.

Also, the hardware KRX3 also has much better dynamic range than the PC 
based SDR approach. On the order of 30 dB or more for blocking dynamic 
range than the sound card based SDR RX. For anything besides casual use 
this is significant.

On the other hand, the combination of PowerSDR and the K3 -with- the 
KRX3 sub RX, is outstanding. It fully integrates with the KRX3's main 
and sub RX frequency on its panoramic display.

73, Eric  WA6HHQ
