Worked on troubleshooting the PAR radio. Did several things with different combinations of antenna cables and antenna looking for a RFI issue. Nothing seemed to make it better.
Did a wire by wire verification of the radio wires to the intercom, all correct like expected since it works to some level. Verified that the three shielded wires were shielded and the wires were good to ground. Still a bad garble. Turned sidetone up on the radio and now I have sidetown, but it is very garbled.
