Working on hooking a rigblaster nomic to a Icom 25a mobile radio for echolink. The Icom key line needs to be pulled to ground to key the radio. The nomic is only making it down to 1.5 volts. It's enough to make the tx led on the radio come on but not down low enough to actual key the radio. I've tried to come up with a circuit to pull it the rest of the way but not coming up with anything that works. Any body been down this road before me? A diagram of something that would work would be nice.
Thanks for any help or suggestions. Mike KA2NDW
