Hello, I just hooked up my new TS-64 to the MSR2000. I did it this way: Black to pin 1 Squelch Gate (GND) Red to pin 12 Squelch Gate (+V) Green to pin 10 R1 Audio (JU1 removed) discriminator output from rx Blue to pin 13 R1 Audio, High pass audio out of TS-64 White to pin 14 Squelch Gate PL indicate, line pulled to +12 with 2K, and to CAT500 PL input Gray to LINE PTT on MSR2000 backplane Orange to CAT500 pin 10 DB25 PTT Yellow to pin 11 Squelch Gate Tx Audio (TS-64 tone out) Violet to pin 13 Squelch Gate (Local PTT) idles high, no local mic installed
I set the DIP switch as follows: ON ON ON OFF ON ON = 141.3 The Squelch Gate card is removed. Jumper clipping the White to ground mutes the MSR2000 audio. Verified power going to TS-64. TS-64 does not mute the rx audio. With PL indicate line high, CAT500 attempts to transmit via PTT going to TS-64 PTT input. TS-64 does not take it's PTT output low however. Factory defaults on TS-64 jumpers, none set that I can tell. It was my intention for the TS-64 to keep the White low until tone is heard. Then it would release that line, telling the CAT500 we have PL, then the CAT 500 would key, then the TS-64 would key. Upon CAT500 release of PTT, the TS-64 is supposed to reverse burst and delay a little. Thing works fine without TS-64 if I manually do PL indicate with a jumper clip and hook CAT500 PTT to Line PTT on MSR2000. Any one out there that has experience with TS-64? BTW I tried ALL the tones on the input freq. TIA and 73's Glen K4KV Colquitt County Ham Radio Society Moultrie, GA WD4KOW repeater 146.19/79 near Sumner GA 600' AGL
