Interesting. Going by the prices on powerwerx.com, 250 feet of 16-gauge wire, plus one of these repeaters, costs less than 250 feet of 12-gauge wire alone. You save about $20, even at the MSRP for the repeater.

Clubs that use Digitrax DCC might want to re-think the 12-gauge wire specified in the new NTrak DCC RPs. (The PowerPoles are still a good idea, though.)

Rob .. I don't believe this has anything to do with the power distribution buss on the layouts ..

I think this device is more like a LAN repeater .. which would be good for larger layouts .. where you can bring down the voltages on the loconet when you plug in more throttles ..

12 Guage is still a good practice ..

Okay. I thought the primary reason for going with such heavy wire (heavier than most house wiring!) was signal loss, not voltage drop. But I can't find a reference to back me up, so I may be mistaken.

If voltage drop is the primary problem, then obviously my idea is bogus. Sorry... :(

This is welcome news. I picked up one of the new Micro-Tsunamis and its well worth the price over the MRC steam offering, there really isn't any comparison, even with the small speakers in an N-scale tender.

Not to mention the fact that I've been waiting on a pair of their less expensive LC line to do a pair of HO diesels for someone for over 2 months, it would be nice if they actually made some more of these too.

And diesel in a 16 bit (vs the 8 bit sound samples in most other products) would be really nice. I heard they went so far as to get a person to specifically do diesel sounds and they really are trying to get it right. Of course, just because they are trying doesn't mean they will, but it sure seems to beat some of the very puzzling releases of new items we've had over the last year. The Life-Like GP38-2 without a sight glass with those marshmallow fans and the holes for a winterization hatch or the 'modeler' version of the MP metal shelled F units come to mind. Those products seemed to be made without even a minimal effort to 'do it right.'

Rob,
The repeater is for Loconet.  Some users with large numbers of loconet devices and connections have reported trouble with drooping voltage/current on the network cable. The repeater will boost the signal on the net so it can be run longer distances and handle more devices. A couple of these in the large layout planned for Derby City Express next year should make for a more reliable Loconet.
The cables and connectors used to power the track are part of the track bus. Still need to keep voltage drop at a minimum at the rails.

Because DCC works at a relatively high frequency, there is the "skin effect" where the signal travels on the edge(skin) of the conductor, therefore causing a greater signal loss over smaller wire than would normally be anticipated. Learned this working on USAF aircraft using 400Hz AC power. Voltage loss at 12-15 volts is always an issue too. "Grasshopper, bigger wire is always better..." 8)
