Hi All! This over protection module is something that you can buy in stores or must be built ? I am using with my 6700 a Astron RS 70 - M ( 70 amper). I have it since many years. Reading all this emails I must take a look of its output!! How can i do it? it is so simple like conecting the osciloscopes probes at the output with the transceiver at work?
