GE Phoenix Resources

 

This area contains general manuals, schematics and documentation for the GE Phoenix SX and PSX radios. The parallel port programming hardware and the EPROM data structure information is based on the original work of Gary Marsh VO1CPU. Gary and others did the original pioneering background work here. I have built upon the work of Gary and others to create the GE-Flash and PSX200 programming applications for Windows. You can visit Gary's website for additional Phoenix info.   Special thanks to Mike Swiderski K4HBI who gave me my first GE Phoenix PSX-200 radio and turned me on to these great radios. Also, thanks to Gary Benjamin and Doug Bennett for their help testing and debugging the PSX200 software and hardware. Gary and Doug provided valuable assistance with the scopes, logic analyzers and hardware debugging during the initial testing phase of the PSX200 project. Also, special thanks to Larry Waggoner WOKA who helped tremendously with the software debugging, programming details and testing on the various Phoenix models.

Microphone and Connector Wiring

Many Phoenix Radios used the CES 600L microphone with an optional touch tone pad. The CES microphones are still in production and have a number of internal configurable options available (mic & tone gain, etc). For complete option details view the 600L owners manual in PDF format.

CES 600L Microphone Wiring

Color	Function	To Radio P911
BLUE	+12V DC INPUT	+12V *
RED	PTT (logic low)	2
WHITE	TX AUDIO OUT	4
BLACK	CTCSS HANG UP (logic low)	N/C
SHIELD	AUDIO/LOGIC GROUND	3
YELLOW	LOGIC & POWER GROUND	3

* The BLUE +12V wire on the CES600 microphone should be connected to a switched +12V line inside the radio. On my radios I found the switched +12V power at point HL57 (one of the inter-board feed through pins located on the top board near the front panel). I then used one of the extra pins (pin 8) on P911 as my +12V power source. Note on the SX I had to cut a trace on the bottom side of the board in order to use Pin 8 as a microphone power pin; on the PSX-200 no trace ran to this pin and I just ran the wire from HL57 to Pin 8.
