I use it for two things: 1) Diversity reception. I find that weak CW reception is greatly improved with diversity. For example, on 40M, I use a dipole connected to the main antenna and a small vertical on the subreceiver. When the signal fades on one antenna, it often comes up on the other. And the response to noise seems to be different in the two receivers. The result it that far fewer characters are 'questionable', and copy is easier. 2) Pileups. I listen to the DX station on the main receiver and the pileup in the sub; the K3 is in split mode so it will transmit on the sub's frequency. I have the K3 set up to use the same antenna in this case, but I use a narrow bandwidth in the main and a wider one in the sub. I have set the K3 to send the main signal to both ears and the sub only to the left in this mode. This allows me to easily pick out the station that the DX is working and be on the right frequency when I call him. This sounds complicated, but the K3 is designed to do this stuff (the antenna setup is sticky for diversity/non-diversity, and the channelization of the audio only affects non-diversity). Combined with the macro capability, it takes ONE button-press on the K3 to activate either of these modes. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
