It's hot. 13.8
Hey Lil
If you have a volt meter can you measure the output of pin 6 for me, I will be ordering one of these 8900's in the next few weeks and I also would like to run a road devel mic on it cheers
See above picture. Use 1,3, 5 and Pull pins 2, 4, 6 for RD104
Here it is. If you run the radio on a regulated power supply then all you need is a few diodes to step down the voltage. Each diode steps the voltage down .6 volts. You might have to run a ground wire as well to cut down on a chance noise entering (ground loop)the audio stream.
You make a post like this, but then you ask how to wire a RD mic to the 8900?
Mmmmm
I was able to get my RD mic working decently by turning the gain on mic way down and menu mic gain to about 31-35 per cbradiomagazine's suggestions. It's doing pretty good. Got a good report from my cousin around 30 miles away on ssb. Said it sounded "damn good". Now I just need to talk to some friends on am and see if its any better. I still wanna ground the radio chassis to the jeep chassis. Also still have a 1-2 second delay between keyup and audio actually being transmitted. I've never even heard of that till I tried the astatic 636l on it yesterday. Must be an astatic thing. I need to find out what relay solves this and where to put it.
