I'm trying to use a Connect Systems CS-800 interconnect to key a GE MLS 1 to transmit. I'm not overly familiar with the MLS 1 nor have I been able to find any LBI's online relating to my specific VHF version, MLSH040. I've listed the pinout of the rear connector on the MLS below;
PIN 1 EXT SPK HI 2 PTT/CLOCK 3 MIC LO 4 MIC HI 5 PTT-/A- 6 EXT SPK LO 7 CG DSBL/DATE 8 STORE On the CS-800 interconnect there are connections for Audio In, Audio Out, PTT, COS, GND. It also has a relay switched PTT connection if the radios unkeyed PTT voltage exceeds 16VDC or if inverted keying is required (closure to 12V). I've tried the obvious connections between Audio Out and PTT but I just can't seem to get it to work. Also, the radio was recently tested and the interconnect was working on two of my other radios. If anyone has had any similiar experiances with this radio I would appreciate any help. Thanks, Steve Yahoo!
