Re: Need interface cable or instructions on building one


 

I built this for a Henry amp to Kenwood TS-850 and TS-870. There's a pin on the "DIN" socket that has 12 volts (power supply voltage) on transmit. Pin 7 in my case. Use that and ground.
Pin 7 (in my case) has a maximum current draw of 10mA. This circuit draws just under 4mA on transmit.
You need to verify the pin number and maximum current draw for your radio. My Henry amp has a spike of over 200 volts when TX relay disengages. That's why that darlington was chosen.
If you build this you can test it with 12 volts DC and verify current draw etc before you connect to your radio and amp.

I have a Kenwood TS-590sg and recently acquired a Dentron GLA-1000 amp.? Needing to interface these two devices. So.. if someone has a cable that would work.. or a connection diagram I could use to build my own.. That would be pretty awesome.
