Batboard

Hi there I'm new to the Batboard & this is my first post. I'm wondering how I can get both RX & TX audio to the 15 pin port on the back of a astro spectra mobile. I want to record all comms. I was able to get the RX audio there via pin 21 from the ACCY connector on the command board by moving a jumper allowing the disc. aduio through. I havent been able to find a way to get the TX audio. Any help would be of much use. Thank you.

found it! TX can be pulled off of R415 on the command board. Now I just need to sum them together.

Try a Recording Mixer it should do the job.

I think it is pin 11 on the rear accy connector of the Astro Spectra that gives both RX and TX audio mixed.
We use it for recorded audio all the time.
I know there is a jumper on the command board associated with it. I will look it up and post.
