As mentioned earlier, we are producing the prototype run of low pass filters for your homebrew or kit type transmitters of 20 watts output or lower. By limiting power to the QRP and low power range, we hope to be able to produce a kit for a very reasonable price. These will work for one band,  We are concentrating on 80 and 40 meters to start with. As always, we will include a well written do it yourself instruction book. The final parts for this prototype run are being air mailed in now. Stay tuned!
