After I had developed a couple of short-wave and VHF-FM Receivers in my spare time, I decided to develop an allmode Receiver for the 144 MHz amateur radio band as my university graduation thesis. This receiver has to be able to receive frequency modulated signals as well as single sideband (SSB) amplitude modulated signals at 144 MHz. The project was supervised and evaluated by Prof. Dr. Ott at the Georg Simon Ohm technical university in Nuremberg, Germany. All copyrights are to the university which means that you must not use any of these circuits for commercial developments.
should be interested in even more details than given below about the circuits
or about the measured data, I will be happy to give it to you on your
