Did a little work on the transmitter. Put in the ceramic mounts for the balanced modulator and drilled two boards (so I have a spare).
The balanced modulator will be built "dead bug" style using the copper surface for a ground plane, making it stable. The screws are in ceramic insulators, so the board is not grounded, there will be ONE ground to the board, to prevent ground loops.

Hardware not tight, it will be level!
