Triple 7's mic mod includes trimming down the RD's volume slide control and make it a internally adjustable. I'm going to hook up a modulation meter to it to see what kind of numbers I get,and to set up the RD to the radio. It's a lot quieter radio on receive than the DX-959 and has fairly good modulstion. It's a nice radio for the price and rock steady on frequency. Tap in to 13.8 volts that's on one of the radio's mic pins and use it to power the RD instead of it's battery and replace the red case(Triple 7's mod)with a chrome one I bought from DNJ. A 1K resistor will go between the audio and the ground in the RD mic. When I get the Road Devil mic I'll wire it up to the 6 pin mic plug. I want to be cautious and not blow out a trace like CBRadioMagazine did with his 8900. I just got the mic adapters in today to run my 2018 mic on along with a 6 pin RCI jack that's not wired for a 8900.
