Ever since I first head about it, I've been interested in Tam Valley's radio DCC system.  Now that I finally have the budget for it, I'm considering making a purchase.  Before I do, has anybody used it, and can you comment on it?

Using a Zephyr DCS 51 with a programming track.

Bought (4) TCS  T1's  put three of them in older yarders. reset their CV's to 111, 222, 333, 444.

111,222,333 all can operate in forward and reverse. The white wire is front light and it is on the minute I put the loco on the track. No rear (Yellow light) ever lights. Have moved all three decoders from one loco to another and the same occurs.

I will start off now and say i'm sorry if I offend anyone and that this may have been an isolated incident.  

About a week ago I picked up a Bachmann DCC GP30 for $50 at my LHS - Thankfully!  My son liked it and had no problems running it, but it was loud (Motor noise) and jerky.  The loud motor noise I could have lived with since we were upgrading from a Bachmann DC starter set, but the jerkyness caused constant uncoupling and turned a fun time for my 10 Year old son into work time having to stop and recouple the cars every 10 minutes or so.

I've seen a number of posts here lately that say something like "After I connected all of my feeders / electric I had a dead short."
