Super Pro Mods Article - September 1958 CQ

I have (in gif format) a copy of this article. If anyone wants the file - e-mail me.

Mods in the article are:
1) Product Detector
2) Improved frequency stability in the HF oscillator
3) Improved AVC action
4) 3KC bandpass crystal filter
5) Improved RF sensitivity & resistance to overload & cross modulation.
