Hi everyone.
Here is the situation.
I have a Motorola XPR radio receiving a fire department.
Speaker have been disconnected to prevent local audio specially at night.
Audio output is from the rear connector and goes to an isolation transformer IN-OUT then feed the sound card dongle on the PC running Zello Work and Zello standard.
I would like to tap on the audio output from the XPR to feed extra devices.
Like a local amp/speaker for local listening in my Ham Shack and also feed a Bluetooth local transmitter so i can keep listening while doing some work either in house our around the house outside without have to use Zello App on a cell or PoC radio.
That said i need idea on how to split the audio without inducing noise or ground loop.
Right now i have this setup below and proposed setup.
Any comments or suggestions
