Title: 812 Rig - More Progress
Post by: KA8WTK on January 07, 2007, 04:52:02 PM
  After the RF deck it was time to move down to the VFO/driver deck. In this rig a Navy CBY-52208 transmitter has been modified to control frequency and supply drive to the push-pull 812's. The frequency is 3 to 4 megacycles. Does anyone know where an article exists that could help me detail what some of the changes would be and help to identify the network shown in the potos?
  The first picture shows the unit out of the rack. The next picture shows some of the internal modifications and the output network in a seperate box bolted to the back of the top cover. The last picture shows the cleaned-up unit ready to back into it's holder.
  More to come...............
