I heartily second it. Ed's passive filter is inexpensive (I think,
it cost me $20 six months ago) and came assembled (almost!) in a nice
case! Works like a charm and I would suggest it anyday when somebody
is trying homebrew a CW filter. It took me about 30 mins. to put it
together and it was very easy. Go for it. It will be bux well spent.

PS: I am just a happy customer. I am not connected to Ed Wetherhold
in anyway...blah, blah, blah.

        Go for the CW filter that has been in the ARRL handbook for the
last few years. It was designed by Ed Wetherhold, W3NQN, and it works like
a champ! Totally passive, not requiring any power, it goes between the
audio output and your speaker or headset. I've had mine for 3 years and it
works just like it is advertised, fantastic!!! I sent for the parts and
the toriods were free...I had to pay for the capacitors, but geesh,... it
was cheeeeep!
        If you don't have the ARRL handbook, go to the public or university
library and check: TK6550 R18 or around that area in the library.

I'm not finacially connected with Ed, but I sure endorse his design!
