I'm busy enhancing some DCC-friendly HO turnouts, following Allan Gartner's excellent website. Has anyone had experience performing similar solder connections on the double crossover? Some locos are

Mike, You can't fool Mother Nature. 40v for 200nSec across a 100 ohm resistor 8,000 times/sec is only 3.2 micro-watts. You have something wrong with your set-up. Wrong value of C or shorted C or a

Hi Don, In your calculation, you used 14 volts in your formula. But I have 40 volts peak for 200ns. It sounds like the power would be the .156 watts at nominal voltage, PLUS additional power when it

Sorry folks I goofed Resistor dissipation of series R-C across DCC track bus is Pw = 1/2 X C X V^2 X ~8kHz X 4 (not 2) So for a 0.1 uFD cap and 14.25V DCC, the resistor heat will be ~0.32 watts.

Mike, sounds like you have a shorted cap! [ the R & C ARE in series...Right? :-) ] e^2/R = 1.5 watts for 130 ohm resistor directly on a 14V DCC bus For cap & series resistor: resistor Pw = 1/2 X C X

Hi All, I recently scoped the DCC signal at the far end of my booster districts and saw considerable ringing and excessive overshoot on the rising edges of our DCC signal. After reading previous post

I knew I had worked on a page to explain transpondiing, and it had to be somewhere. Well I finally found it. Still needs to be cleaned up, but here it is.

Mike Possibility 1: You need a wire from the booster ground to pin 11. Possibility 2: You need one detection section wired up and working. Leave it connected, don't remove the wire and then connect up

Just a thought, You do not need to select the loco for detection, but you do need to select it for transponding. Did you try to run the loco on that short test track? If the loco is transponding the

It sounds like you have your acceleration CV set too high. Set CV3 to 0. Your problem should go away. Once you are sure your problem is gone, you can program CV3 to any value that gives you

I think the biggest problem with transponding is the cost. I'm not saying Digitrax is overcharging (I'm sure others will :-), it's just that the shear number of transponders, detectors, and BDL16's

wrote: I've been using it outdoors on my G scale layout for several years. While detection using the BDL is a real pain outdoors, the transponding is very reliable. I have more than 50 transponders

Hi Allan. I'm also interested in getting this to work, but am not quite as far along as you are. I did notice that DigiTrax decoders seem to come factory set with transponding turned off. (I'm not

Well, OK. Pick any signal diode - get 2. 50 V or greater, 100ma or greater. Its just not critical. 1N400x, 1N914, 1N4148, whatever you can find in your junk-box or at Radio Shack. The cathode end of

After looking again at the output capability of the various stationary decoders, 160mA seems high. I found this "low signal" relay from Mouser which seems more appropriate:

I wanted to add to Don's advice about using accessory decoders for stall type motors. That is true. However, you can't use just any relay. Check the maximum current the decoder can put out for a stall
