Hi Retired Handyman,
This might be ancient history and I'm anything but well versed about the capabilities of the various DCC systems. But while attending the 2011 NMRA convention show I spent a bunch of time at the DCC Mfg. booths. Saved the CVP booth for last and after visiting with Al and handling the T5000 wireless throttle it was Easy DCC for me. I immediately liked the T5000 throttle and it felt right at home in my hand, Al's friendliness, knowledge and helpfulness was impressive, so too CVP's history in robust garden railway control.
Those guys at CVP were a great help in guiding me thru set-up via email and phone, and more than patient in increasing my understanding of DCC while answering all my dumb questions. Have now been enjoying my CVP system and their fantastic customer service since 2012.
Good luck and regards, Peter
