Not here Geoff, but I can't really tell. I assume there will be distortion any time one goes "whacking great holes" in the spectrum of a signal to blank noise pulses, and that will vary widely based on the strength of the signal, presence of nearby signals and many other factors.
IIRC the exact nature of the process based on the settings for the NB in the K3 has changed from firmware rev to firmware rev too. Ron AC7AC -----Original Message----- Dave, It's also my impression that the DSP noise blanker introduces more distortion on SSB signals in Firmware 4.22 than in previous firmware. I haven't rolled back to a previous version to check it out like you have but I will next week. Anyone else notice this? 73 to all Geoff G3UCK ______________________________________________________________ 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
