If you are suffering any noise, hum or buzz in the audio of the feeds, this device seems to be the go in fixing that.
Simply Connect the "Isolator" into your Audio out Jack on the scanner, and AUX cable to the other port of the Isolator. No Chopping/modding cables needed...
They are only $9.95 from Jaycar, and i have bought several and they work a Treat!
They improved the Audio nicely when i connect remotely via Proscan & Freescan and the Audio is nearly Perfect!
Also, i am using them for POCSAG decoding, check ou the thread below on that one as well...
