Thanks guys for the suggestions, duly noted ham fest season is just around the corner. My receiver does have the Sherwood audio amp mode in it and it is really surprising how clean the audio is. To be honest I might try the Timewave on my OMNI 6.

(Don Jones) IMHO, the only thing that is better than what Don describes is the R-4C as he describes BUT.......use a Timewave 599ZX with a pair of noise canceling earphones (the Bose are expensive, but quite comfortable). The Timewave has a superior audio amp and I set up the filter as a bandpass with the low end at ~300 Hz and the high end at 1,500 Hz. This helps with the low end "rumble" and the high end atmosphere noise and makes the radio even more enjoyable. I rarely use the other features of the DSP filter, but on occasion, the "Random" function does help. Only on few occasions do I use the CW function of the DSP. It does help also, but for the most part, the R-4C audio into the DSP filter is "clean". I have recently aligned my R-4C and used the headphone jack with out the Timewave and again realized what a huge difference it makes. The DSP filter is not low cost, but I got it 10 years ago and it is still a viable solution. I am sure that there are lower cost filters out there, but can not attest to the audio amps on them. One of the cost drivers of the 599ZX is the ability to go to 5 kHz as the upper cut off frequency. This compares to others that have a cut off at 3 kHz or so. For amateur radio, the 3 kHz is fine, but I also use the 599ZX with my Drake R-8B for BCBDX and Beacons.
