Hi Matt, you can find a DOS program called 'atten_22.zip' by OH0NC at http://www.rmham.org/files/misc/index.html.
This enables you to calculate a Pi or T pad for a given input and output impedance. Note that if the input to output transforming does not correspond to your specified attenuation, you get negative resistor values. In this case increase the attenuation. vy 73, Alex DF2UZ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
