Ok. Put the little op-amp together via the Repeater Builder website. http://www.repeater-builder.com/rbtip/audioamp.html I did the one with the 15k resistor and .0047uf cap. Couldn't tell you what pot I used. Grabbed one and threw it on. Going to look thru my junk later this week and get a 10 or 50k and try it. Because the audio is still real low and REAL distorted.
However...with what Ron said...made me think about what another friend of mine said. Isn't the ADI looking for something like 600ohms? (like a hand mic would be) Much different than an 8 ohm speaker. This same setup works with a TM-G707 without any matching...why shouldn't it work with the ADI?
