How do I make the DSP bypassed by default when I power up my K2?

Myron,
You are not able to do that, but what you can do is set the KDSP2 FL1 position to LoPass for CW, SSB and RTTY (if applicable) - NR and NT off. That will cut the high frequency hiss and do nothing else. If you find you need additional DSP filtering, then hold the AFIL button to change to FL2, FL3 and FL4 to give you additional degrees of DSP filtering. I would suggest that you narrow the IF passband using XFIL as a first measure to eliminate QRM and noise before narrowing the AFIL setting. The KDSP2 DSP is in the audio path only where the XFIL settings narrow the IF channel. Note that the K3 is different, the DSP is processed at the 15 kHz IF frequency rather than at audio frequencies - so in the K3, the DSP determines the bandwidth of the IF channel. 73, Don W3FPR On 12/30/2014 6:43 PM, Myron WVØH wrote: > How do I make the DSP bypassed by default when I power up my K2? > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
