GB7WB Modifications to FX5000 Transmitter For D-Star Operation.

To modify an FX5000 VHF or UHF for D-Star GMSK operation simply add a 47nF capacitor across C493 (22nF) which is next to IC403 (TL072) in the transmitter driver module.
Then remove C536 (10uF) which is next to IC504 (LM324)

No modifications are necessary to the receiver module.
