Hi All.
I've just converted to DCC. The experience was a whole bunch easier than I imagined.
I have a Bachmann diesel that came with DCC on board. I also have a Proto 1000 that I converted with a basic decoder.
I have found that the Proto 1000 runs a lot faster on the flat than it did before, but it looses a lot on a grade, this problem requires that I be a lot more attentive when setting the speed.
I also have to be more attentive when running two units at the same time, I've had a few minor collisions and derailments, all due to operator error.

I need some help selecting the right decoders for the next two units.
I have a Model Power USRA Pacific 4-6-2 and a Bachmann Spectrum SD 45, I would like to install a decoder with sound in both units.
Although I don't want to go CHEAP and NASTY, cost is an issue, Her Royal Highness holds the purse strings.
Any recommendations would be much appreciated.
Thanks in advance
Mac
 
Basic decoders that lack back EMF (BEMF) will tend to run away going down a grade. I use Digitrax DZ125 decoders with BEMF and have almost no problem with runaways on down grades. While the DZ125 is a basic Z Scale decoder it's more than robust enough for use with HO equipment. I use them in Athearn Blue Box locos. I have some on the layout right now. A pair of Athearn GP38-2's, a pair of Athearn SDP40F's and a pair of 70's era Atlas GP40's that all use DZ125's. Digitrax decoders can be set to certain speed tables. I have mine programmed at settings between the lowest (switcher) and medium (road locomotive) settings. These give me realistic scale speeds as well as realistic acceleration and deceleration. The DZ125 can fit into very small spaces where space is at a premium.
 
Hi Jefferey.
Thanks for the response.
Not sure I know what a DZ125 with BEMF is?
Is the BEMF something to do with sound??
Thanks again

decoders that can read the ammount of back EFM (it also needs to be programmed to enabled as it is not by default) can keep your motor speed relatively constant no matter the load, ie increase power to keep speed when climbing and decrease when rolling down hill. cruise control basically.
no experience with it yet though.

this decoder has back EMF detection, however the manual says certain types of earlyer motors might not be completely compatible. Jeffrey, do you know if this means the Athrean BB loco motors?

I have no problem with BEMF on my Athearn locos. I do however avoid MRC decoders like the plague. I've had two non-sound ones go up in smoke on me within a days time. I bought them because I could get both for half of what a Digitrax decoder cost. Not a good deal. I haven't touched any MRC decoders since.
