"Webby Harry Lythall - SM0VPO. Ok, I am back on the receivers again. It seems that many QRP circuits are all usually transmitters but I believe that receivers are quite important too. In this project you can build a SIMPLE receiver for VHF NBFM and the only active component is a diode. Yes, it's a crystal set! " - Harry lythall

http://sm0vpo.altervista.org/antennas/frameant.htm Webby Harry Lythall - SM0VPO. This project is dedicated to Patrick. It was inspired by the e-mail question "How do you measure the impedance of an antenna?". The simple answer is that it does not really matter too much. If an antenna impedance is a little too high then the losses are still too small to worry about, but there are methods of ...

Webby Harry Lythall (SM0VPO) This project was developed as a result of experiments to become QRV on 80 meters, again, using the little balcony of mine. I have now built several of these antennas with equal success every time. The frame antenna may not be the most efficient but it can get you QRV on 80 and is ideal for boats and holidays. http://www.sm0vpo.altervista.org/scope/oscilloscope-timebase-digital.htm
