This new P3 Beta Noise Blanker feature works very well for me here. I am plagued by electric fence clicks and while the K3 NB does a great job of eliminating the audible clicks I could always see them on the P3, displayed as horizontal lines in the Waterfall and base line jumping in sync with the clicks.
Now with the P3 NB engaged this annoyance is eliminated. Great job! Many thanks Alan and Elecraft. 73 F5VJC On 24 April 2014 22:13, Alan Bloom <a...@elecraft.com> wrote: > > > New P3 beta software, version 01.28, is now uploaded to the Elecraft web > site: > > http://www.elecraft.com/software/P3/elecraft_p3_software.htm > > This requires K3 firmware version 4.25 or later and if you have the SVGA > option, SVGA firmware version 1.16 or later.
