The "original" circuits consisted of a number of PDF files containing the circuits for major sections of the PD-8 Transceiver.

These "originals" were copies taken from an original Handbook and many were not easy to read and had many blemishes and hard-to-read component values.

It is believed that the origin of the copies of the Handbook Circuits was the "Radista" website - but this is not known for sure. 

Each circuit file was inverted to produce a "Black-Print", rather reminiscent of a "Blueprint", to improve contrast to the eye when viewing the Circuits on Computer.

Each Circuit file was further processed by removing spots, blemishes and smears.   The readibility of individual numbers and letters was improved, provided it could be firmly established what the value should actually be.  If there was any doubt, no change was made.

This was a painstaking process, but the result is Circuits which are much easier and nicer to look at and understand.
