Thanks George, I have found some simple transistor interfaces and will
be building on early next week for my Paragon.
I just couldn't find much discussion online from folks with Paragons
but plenty of Omni and Corsair chat. Not all radios require a
transistor in the interface, Omni 5's, 6's, and 6+'s can key FSK
directly off pin 3 of the DB9 through a 1K Ohm resistor.
