First off I'm glad to be back, been lurking though, left model railroading for about 2 years, kinda burned out for awhile and pursued other interests, LOL guitars and singing country music all over West Virginia, love it and made a lot of knew friends and met a few model railroaders along the way too! A lot of train songs. Here's my concern, I really want to upgrade from EZ Command to Dynamis and the only reason is to be able to use more of the functions and other goodies in my sound decoder loco's and engines. I have been programming cv's with the Digitrax PR 3 on a mobile programing track. I don't operate more than 3 trains at one time, but could do 6, but I like the idea of 4 digit address's and 40 entry's. My concern is in the title I've read on some forums that flourescent lights interfere with the transmitter signals. If that is the case does anyone know of a filter either for the lights or the DCC command station that I can use? Thanx in advance, Jim (Rangerover)
