It just take a little getting used to to tune in the signal on the correct side of zero beat.

It should have a 500Hz filter--but it is an audio filter, not crystal. If you can live with th; /archives//html/TenTec/2017-12/msg00098.html (7,822 bytes)

Its advantage over direct conversion is freedom from hum and images (wrong sideband). __________________________________________; /archives//html/TenTec/2017-12/msg00104.html (7,668 bytes)
