A program to decode morse code (CW) via sound card to text. It can work as narrow-band sound DSP-filter also. No additional hardware required — you need only receiver and computer (5x86-133 or better) with a sound card. Can integrate with AALog logger. It is a software morse decoder that really work!

Bent element yagi for attics. This is a horzontally polarized three Element Yagi. The bent Elements cause very little performance lose. When you consider it is only 8ft. 5" wide and 7ft. 6" long and still has 6.2dbi gain and 20db front to back ratio. And when you off center feed it you get a perfect 50 ohm match to coaxial cables.The SWR is less than 2to1 for 600khz. Not bad for a Antenna that the neighbors don't even know exist.
