Amateur Radio Receiver

Funway Electronics Project 19

Geographic & Historical Alert – this project and project 20 were originally developed in 1979 when there was significant traffic on the 2MHZ – 6MHZ frequencies. There are fewer broadcasts in this frequency band today. These projects are still included for their educational value.
The integrated circuit used in the beer powered radio (Project 14) can also be used to make an amateur band receiver with minor modifications.
It will also receive aircraft, ships and overseas short wave broadcasts, especially during the night. It covers from 2MHz to around 6MHz.
