Previously, I had built the Lindsay superhet, which was a tremendous learning experience. |
All simple direct conversion receiver designs suffer from degraded selectivity performance and are more subject to overload by contrasted to even modest superhet designs. |
As part of the marketing effort they issued a circuit for a 2 waveband superhet using 6K8,6K7,6Q7 and a 6V6 valve with the HT derived from a metal rectifier. |
Receivers employed a simple tuned radio frequency design rather than superhet circuits, which were considered standard on radios manufactured for American consumers. |
In the superhet or superheterodyne radio, the received signal enters one input of the mixed. |
This circuit evolved from the desire to have transceiver operation when using my homebrew superhet receivers. |
