Japanese Neofight Receiver
In old days there are many "Japanese someting" in Japan. They are American culture translated to Japan. For example the singer who sings the song of Space battle ship Yamato was called the Japanese Prethry. In America they have a neofight (Neaphoit) receiver. It is constructed by NE612 balanced modulator. It is direct conversion receiver. I will show you a similor product. See fig 1!
TA7310 includes a oscillator. It oscillates 7MHz CW. And it is mixed with antenna signal by a balanced modulator. TA7310 includes an AMP. It is used as a audio AMP. This machine has total 37dB gain. I can hear CW and SSB signal with my dipole antenna.
