My self being new to DSC cords> I have a question. If I am right could this be the problem.
When you plug in a DSC cord you leave the tx switch off. If you turn the tx on with the module in and the DSC cord pluged in does the radio transmit? Or does the DSC cord turn that part off.
Myself not knowing. I always pull the module when using a DSC cord.
Is there any way to use a DSC cord wrongly? That may cause Radio interferance>

Thanks
