Greetings everyone, Recently I got the mod done on my Drake SPR4 so the 2.3 crystal filter will work on AM. The filter is very good. In some cases comparing the R/C filter, also 2.3 khz on the R8, the SPR4 does better. It is amazing hearing the difference. But the problem I now have is the audio on the SPR4 is so muddy that understanding is hard to do in many cases. In comparing the 2.3 khz crystal filter in the old SP-600 I had, the audio could be adjusted with the crystal phasing, which the SPR4 does not have. The notch filter helps a bit. I do have an old Radio Shack graffic eq that I could run the audio through. Any suggestions on cleaning up the SPR4 audio? Thanks.
