Rotter is a Recording of Transmission / Audio Logger for JACK. It was designed for use by radio stations, who are legally required to keep a recording of all their output. Rotter runs continuously, writing to a new file every hour.

Rotter can output files in servaral different strutures, including all files in a single directory or create a directory structure.The advantage of using a folder hierarchy is that you can store related files in the hour's directory.

50 Volt Line Transformers

To move audio from studio to transmitter without having the requirement of screened cable I use a 50 volt line transformer.
You need:-
All the part numbers (and photos) are from Jaycar Electronics.

1 x KC5152 Champ audio amp kit

2 x MM1900 Line transformers


Feed the audio into the amplifier and then into the secondary of one transformer. The primary of the transformer feeds over the long cable to the primary of the second transformer. It then gets stepped down to line level at the destination.

Warning!
Don't touch the wires between the 2 transformers. There could be as much as 50 volts AC!
