Hi guys, I experience a strange bandwidth behaviour when using DATA modes with my new K3s. (latest firmware) Maybe I am missing something...
Example: When I select "data" with the mode switch and have DATA A selected the bandwidth is approx. 700 Hz. The bandwidth indicator gives "max. bandwidth" (all the bars). Given the fact that e.g. WSJT uses wide band audio I change the bandwidth settings to maximum, being 4 kHz. (Lo = 0.05, High = 4.05) The bandwidth indicator still gives "max. bandwidth" (no change to previous indication) Now I switch to AFSK A : I get the dual band pass filter for RTTY, as previously selected. So far, so good. However, I almost do not hear anything. Only when I turn "HI" a little bit back and forth I do get the narrow filter response in audio. As a next step I switch back to DATA A. Once again I get the indication of a large bandwidth in the display, however what I hear is quite narrow. Lo is set to 1.15 and High to 1.85. The bandwidth indicator still gives "max. bandwidth" I have to adjust shift/width to get the original/wanted 4 kc again. So I always see the wanted bandwidth in the display, but never hear the corresponding audio bandwidth right away when switching between DATA A and AFSK A. I get the impression that the bandwidth at DATA A has a fixed setting and is not stored like in SSB/CW. The behaviour at AFSK A is not clear to me. (The same happens when I switch to PSK D. No audio as well.) This could all be my error (if so, what am I doing wrong), dedicated design (if so, why?) or a bug. Can someone please tell me what I should do to get the correct behaviour and memory of bandwidth? Thanks! 73 Henk PA0C ______________________________________________________________ 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 Message delivered to [email protected]
