Hi guys, great site. I have a 525 that plays great but I have a 622 that will not hold the signal any of them. I contacted customer support and they walked me through alot of steps and finially decided that I needed a tech. My check switch is going from 1 to 50 instead of 1 to 4. I was wondering if it was the seperator the dpp44 switch or something else. Thanks for any and all help, Mike
