[TenTec] good external noise blanker?

[denton sprague]

Both my Omni 7’s have dsp nr….which is pretty much useless to me when the band conditions get dicey….it works, but makes ssb voice sound gravely. I wind up using a wifi interface between my hearing aids, lowering the b/w to about 1000 hrz and twiddling with the af and rf controls.
Anyone using outboard noise blankers that will do a better job?
Times like this I really miss my old broken Orion.
