  • Notes

  • This project started not only for fun, also as an exercise to test the capabilities of early radio receivers. Being surprised with the performance, then decide to realize this model following the aesthetics of early radio equipment, using antique components wherever was possible.
    This two-step tuned receiver with regeneration, has lower sensitivity but almost similar selectivity and better noise rejection than standard superhet receivers.
