Topband: KD9SV-OK1RR relays ??? (RX Front End Protector)

[Lee K7TJR]

  Sorry Charlie, I don't think I made my thoughts very clear.

  James was quoting from a QST article that there was an impedance
transformation because of the transformers.

This was to make a higher voltage at the diodes. My point was that if the
transformers being used on their circuit board are 1:1 then there is no
impedance transformation and the diodes are fed with the straight RF from
the RX antenna at the 50 ohm level. The design must have changed after the
QST article or something. The QST description is incorrect if they are using
1:1 transformers as shown in their circuit board pictures.
