Dual RF Final Conversion From Single Final Board
One of the best ways to increase the
output of any single ended output cb radio is to add a second output
transistor. This is not very practical with many units as the extra space
is not available.
However, the Connex 3300 and the Galaxy DX-radios which do not have
two Rf finals use the same pc board as the double final units.
Below, you will find the RF output circuit for the single output
stage such as the Connex 3300, the Galaxy DX-33 and the DX-44 and the RF
output circuit for the double output stage such as the DX-88 and DX-99.
The various units will vary somewhat from these schematics but using these
versions will work in any of the units that use the ept360014B pc board.
Armed with this information, along with a my visual layout, it
becomes an easy task to convert a single-ended unit to a dual final unit.
