Hi, Thanks to everyone for there feedback regarding my bassy audio. I have now downloaded Spectrogram and read N0SS's K2_SSB_Gram notes (17/01/2001). I struggled a bit to find the correct settings with the latest version of Spectrogram but have made a start with the following settings
Sample 22k Mono Scope 2 Plot type signal Averaging 1second Spectrum DB/hz max 30 Freq linear Fft 2048 Freq res 10.8 High band Limit 2570 Low band Limit 0 My K2 #4039 is using the unmoded 2.2 (Revison D, Jan 8, 2004) SSB filter I do get some vaguely sensible graphs(!) But I have a few questions! 1. Are these spectrogram setting optimal? 2. What upper and lower frequency markers should I use? 3. Mention is made in another doc of placing a 10Ohm resistor to ground if using the headphone output (as I am) do I need to do this if so where should the resistor be placed? Or should I use the speaker output? 4. Any other suggested documents hints etc? Thank you very much!! I just want to get my K2 set up nicely and work some of you guys!!
