[Amps] Emtorn DX3 problem

[Will Matney]

Lon,

Is this modem an external device? If so, have him to take some aluminum foil and wrap the modem up good, shileding it, just letting the wires come out. Take a jumper lead and attach one end to the foil and the other to a good known ground. Try it out and see if the modem kicks out. That will tell if the problem is from an emmited RF killing the modem or it's coming in through the wiring. There shouldn't be any RF with the amp in idle but who knows?
