John, I sure it has the voltage but does it have enough current ? You may need to buffer it with a transistor. I would think that it does not need it. However, are you sure you logic is correct as-is or do you need to invert it? Try feeding cos line +5vdc (or ground) without the cos line and see if it triggers the system. ...mike/kb8jnm
Is the 0-5 Volt COS swing on a Kenwood TKR-850 sufficient to switch the COS on a DMK URI? Can't seem to get my system to repeat. I'm out in the 'boondocks' with very few parts and a long way from a Radio Shack. Just hoping I don't need to buffer the COS somehow to get it to switch.
