The main PCB used in the Galaxy DX959, DX949 DX2547 are dedicated for 11-meter radios. The main PCB is a hybrid of the EPT690010Z board.

Channeling is done via an additional PC Board using two additional crystals to support 40 channels above and 40 channels below the standard FCC 40. Installation of this board provides a total of 120 channels.

This project is not for novices or anyone who does not have the proper equipment for aligning RF circuitry, or anyone faint at heart. Leave the installation and alignment to a proven technician.

There are two versions of this PCB. Viagra "A" and a newer version called a Viagra "B".

The newer version "B" is much easier to install.
