For years, as recommended by Tony we have been adding an extra, in series, external LPF to our Softrocks.
Now we are getting posts like this.
Is this more theoretical?
Does it really make very much difference?

- If you're using a single band external filter you don't need any switches. That's probably the most common arrangement.If you DO switch the external filters, you should use a 2 pole switch as K5BCQ suggests.
