Suggested by a 1990 book for amateurs, this circuit makes use of an integrated component that is not common today. It converts signals from one band to signals in a 10.7 MHz band below.
The current can be kept constant in the load circuit using the integrated regulator LM350. The...
Found in older documentation this setting applies to modern components, noting that the power...
This circuit is suggested by American documentation from 1970. It makes use of transistors of the time...
