[Elecraft] [K3] Question about APF with Diversity Rx enabled
VE3MV: > As I understand it, (at a high level) with Diversity turned on, both the MainRx and SubRx are turned on, use the same bandwidth roofing filters and the main VFO A provides the same LO signal for both receivers resulting in audio from the MainRx going to the left ear and the SubRx audio going to the right ear. If the APF is now turned on, does the DSP1 for the MainRx and DSP2 for the SubRx now apply that filter functionality to the two separate Main and SubRx audio signals so that turning the shift knob actually tunes the peak in both of the separate audio streams together? Yes, but both VFOs share the VCO reference (i.e. not VFO A driving VFO B). Both VFOs are always tuned together by the DSPs and MCU when in diversity mode. 73, Bill W4ZV __ 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
[Elecraft] [K3] Question about APF with Diversity Rx enabled
GA: Perhaps someone (Wayne or Lyle or ??) could provide some further explanation about how the APF is implemented when Diversity RX is turned on. As I understand it, (at a high level) with Diversity turned on, both the MainRx and SubRx are turned on, use the same bandwidth roofing filters and the main VFO A provides the same LO signal for both receivers resulting in audio from the MainRx going to the left ear and the SubRx audio going to the right ear. If the APF is now turned on, does the DSP1 for the MainRx and DSP2 for the SubRx now apply that filter functionality to the two separate Main and SubRx audio signals so that turning the shift knob actually tunes the peak in both of the separate audio streams together? I'm just trying to get a better understanding of what's going on in the radio. Thanks and HNY to all. 73, Doug VE3MV __ 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
