DITTO!! I could not agree more with this piece of advice. With a tight front end and IF strip I have found the need for a noise blanker to be nil when using the 600Hz roofing filter's and the 500 or 250 Hz drake cw filters. For SSB BW's the need for a noise blanker is nice at times and I do open my receiver up to the stock BW's in order to get the 4NB to work.
One not for the good of the order - the "Sherwood" R-4C did outperform my OMNI 6 (with a full load of filters and the INRAD roofing filter mod) in the pile ups during the recent VP8ORK DX-pedition. We are talking 559 (R-4C) verses 229 (OMNI 6). No comparison.

It has a switch so I can keep it wide if I want (and use NB), or use SSB or CW Roofing filters to keep unwanted adjacent signals from de-sensing the RX. It works super!
