N3DVI: Perfect CW speaker

Perfect CW speaker

This little design is by KD1JV, Steve Weber:

I haven't built this yet-- but I want to. The way it sounds is that this would be the perfect speaker to go in my shack, as I am about a 90% CW only op and my old HW-8 (not to mention my bad hearing) needs all the help it can get.

The design of the speaker is tuned to peak at a 600Hz tone and then attenuates other frequencies to help you in crowded band conditions etc.

I have been drooling over this little design for a few weeks and I intend to build it soon. Steve Weber,KD1JV does a fantastic job as a designer; and I have loved the items of his design I have used.

Homebrew Dipole Antennas

You can purchase one of these from me if you'd like. Email me for pricing and other information at n3dvibill@gmail.com. These 1/4 wave single band dipoles are made using 18 gauge insulated wire and are capable of handling 200 watts of power. They have a center insulator made of 1/4 inch plexiglass and all connections use solid connecting crimp-on lugs and stainless steel nuts and bolts. The SO - 39 is also mounted to the insulator with stainless steel hardware and has been weather sealed on the back side to protect it and the solder connection from the elements. The wire used for the wings of the antenna is flexible. This means that these lightweight antennas are easily put up and taken down, making them perfect for Field-Day, Go Kits, or for camping use. As a permanent instillation they will give years of useful service. These antennas are fully assembled and tested.
