Hi again, A little while ago I wrote the message below. I am still searching for ways to compensate for the tilt in my new 2.8kHz crystal filter. One way would be to have a way to set the RX equalizer through a serial command / macro. Is this going to happen soon? Another way would be to have the RX equalizer settings stored by mode so they could be different for USB and LSB. Is this going to happen soon? Am I really asking too much here? I spent money getting the 8 pole 2.8kHz filter hoping it would solve the tonality difference between USB and LSB, but achieved nothing. Recently there was somebody on here wishing that Elecraft would sort these filters weeding out the ones with a bad tilt. Should I order another one hoping to get one with a flatter response?
AB2TC - Knut Hello all, I recently replaced the 5-pole 2.7kHz roofing filter in my K3 with the 8-pole 2.8kHz hoping to get rid of the difference in tonality between USB and LSB. But the difference is still there. These two links show the noise spectrum of the receiver in USB and LSB. http://ab2tc.getmyip.com:8000/pictures/usb.png http://ab2tc.getmyip.com:8000/pictures/lsb.png In USB there is a definite upward tilt of the passband and the opposite for LSB. This is quite audible. Is this normal and is there anything I can do about it (other than asking Elecraft to add by mode equalizer)?
