Complete semi conductor rebuild Racal 17 (a present from my friend Pieter PA2HDU) The set was in very bad shape. So I get the idee to complete redesign this perfect radio, with semi conductors, no tubes are used. So not a carefully overhaul, but completely rebuild and redesigned.
Some adjustments has to be made, because all the special Wadley Loop filters including the complete (100kc) IF where made to accommodate tubes. Transistors and fet’s have different impedance's especially the coils / filters.
The goal was; use exactly the original Wadley Loop design, but every part adjusted to the use of semi conductors. Also SSB (product detector) and FM are added.
Only hand drawn diagrams / schematics exist. One day I will find the time to make proper drawings. But don’t wait for me, it good be a long wait?
