I have some of the original model of the non-sound DC Revolution RX boards, some of the sound equipped DC RX boards (bought about 3-4 years ago)Finally use the USB dongle with care it will not work with original crest receivers(the ones without capacitors built in) and needs a patch for the early "new" type receivers.
With regard to the US pricing its a permanent sale a bit like DFS
John, I'm not sure about that. There are 2 ways this can be implemented:
1. Throttle sends tokens like (go faster, stop, reverse) to decoder in loco.
2. decoder received the tokens and converts to DCC signals to output to DCC decoder.
This method is very much like DCC system where command station function and booster is in decoder.
This is similar to most traditional DCC systems
1. Throttle sends DCC commands over wireless link.
2. Decoder just forwards DCC commands to attached DCC decoder
This method is like "deadrail" and AirWire
Command station function is in throttle, booster function on board loco.
It's not clear which of these 2 methods is in use. Your post indicates the first method, the way it was explained to me by Navin (works at Precision RC, the manufacturer) is the second method.
I'll have to wait until someone actually determines this.
