The Digitrax PR4 USB Decoder programmer works as advertised! I can easily program my DCC decoders using the PR4 with DecoderPro and totally bypass the command station. Awesome product!

As always, great working with Yankee Dabler. I do have a question. It is my understanding members of the CB&W Model Railroad Club (Grafton VA) receive a partial discount on all purchases. I tried, CBW, cbw,CB&W and cb&w and it didn't respond. Do I have the wrong code? Please advise for future purchases.
