LA6NCA RADIO PAGE
Lo 6 L 39



TRF receiver, 74 kHz to 1530 kHz



This is probably the best TRF receiver that is produced.
It has 6 tuned circuits that follow the frequency setting button.
It has no mixer so the purity of the signal will be very good.
No mirror frequencies or incorrect mixer products occur.
It's amazing to try such a receiver.
It is unfortunately painted with a ugly green color.
It is used by the Norwegian military after the war.
They did not even have the correct olive green color.




A small film about the mechanical details.



Imagine that your radio receiver only consisted of a super-precise filter that could be moved to the desired frequency.
Is there such a thing?
The answer is Lo6K39a and Lo6L39.
Look at this incredible curve.
The signal is feeded in to the antenna input and taken out on the detector.

Ham band 137 kHz.

Ham band 475 kHz.
