Hi,
Anyone point me in them right direction please.
I want to build an outboard adjUstable cw audio filter.
I am rubbish at making pcb boards so maybe a commercial one would suit me.
all replies and any help greatly appreciated. Dave G0AYD.

Loads of them here:

Can anybody recommend a particular one?7

Why look any further..?

They have a good reputation. But they are designed for mounting inside the radio in line with AF gain.
This may not be possible for this user.

I think this one may be a better option.
