    Charge Coupling on the Cheap

    Thought you guys might be interested in this effort ...hope you can make sense of this..

    This afternoon I completed one channel of my first charge coupled network.

    I decide to use the existing 2122H mid section of the 3145 network..charge coupled and the Hf and uhf section of the 4344mk11 network per the schematic charge coupled as I had those chokes in my workshop.

    Also picked up two bags of surplus (100 qty) 250volt 2 uf mains rated capacitors (polypropylene?) for 10 bucks at my diy shop and paralleled them up to make up the values and bypassed them with 0.01 uf polystyrenes.

    Initially impressions are promising. Plan to build up the other channel in a day or two.

    Me thinks its the way to go for a nice low cost network. The most expensive part is the copper foil..left overs from diy Geortz cables!

    This is just mock-up network for evaluation.......so don't cringe too much about the construction

    cheers

    Ian
