Re: Looking for advice on FM regen receivers
Quote:
1930s Amateur Radio Handbooks (from the RSGB and ARRL) have quite a few circuits for super-regen receivers dating from the epoch when amateurs had frequency-allocations at 56- and 112MHz. Some of these were interesting, making use of concentric tuned-lines (for higher 'Q') rather than coils - often nicknamed 'Organ-pipes' for obvious reasons. |

Re: Looking for advice on FM regen receivers
There was a similar thread in 2018. See https://www.vintage-radio.net/forum/...d.php?t=142752
A Google search for "Ataka Super-regenerative" brought up the bibliography for Whitehead's book at Google books. It includes references to a couple of articles in the Sept 1948 issue of the U.S. magazine "Electronics", which you can find at americanradiohistory.com John |
