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.
