"Bob Henderson" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Hi Doug
These things are very different. If you want to enhance CW performance of the R-4C, you need the Sherwood 600 Hz roofing filter. with switching kit. With that you can switch between regular Drake roofing filter, which is fine for SSB and the Sherwood 600Hz CW roofing filter, which is superb for CW. If you're thinking about also adding SSB roofing filters, you might want to use the Sherwood custom front panel switch but if you just want the CF/600 then you can use a spare contact pair on the R-4C mode switch. If you'd like further details, just ask. Forget the GUF-1 filter. Waste of time. I have one and it isn't worth the time to put it in place.

I use the rig for rag chewing on CW (and occasionally SSB) and also for CW contests. The new filter would only be to enhance CW ops during contests.

I'm not sure I'm reading the Sherwood Engineering web site correctly but it *appears* that one would need the filter, the filter switch kit and the custom front panel switch. That option totals $300. > > There is also the GUF-1 from International Radio. It's 8 KHz so not quite the same thing but no doubt a huge improvement.
