Hi I have a K2, serial number 2490 fitted with the KDSP2 board, DSP firmware version 3.18, microcontroller version 3.10.
The DSP appears to be working ok. If I disable the DSP via the display button (DSP = BYP) the audio is muted for a short period of time and then audio returns as would be expected. However if I turn the DSP back on I get a loud crackle from the speaker. The crackle appears when the volume is turned fully down. Increasing the volume increases the loudness of the crackle. From the KDSP2 manual I assume the speaker output should be muted when the DSP board is turned on or off but my K2 seems to only mute the speaker when the DSP is turned off. Any ideas what could be causing this? Thanks Andy _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
