I have a DTMF controller that replies to your commands to let you know if it did what you wanted it to do.... It has a ptt output and audio in and out.
Would it be okay to splice the audio out for replies from the dtmf controller into the TT4 audio out to radio wire?
Wondering if the audio being played on the tiny tracks audio out pin wouldn't hurt it?
And I'm assuming it would be just fine to splice the audio in from the tiny track to the controller, may require volume adjustments afterwards?
It seems like the ptt you could go to the ptt IN on the TT4 and then the tiny track wouldn't step on its transmissions correct???
Working on building a mnt top digi , but don't want to have to have a whole another radio just for the DTMF controller.
Thanks
