Ahh, I was just joshing, Chris.

Truth be told, I am stuck with a whole bunch of QSI-equipped locos.

Sorry Rich, one of the very few times we'll have to agree to disagree. It's not that I'm a QSI hater, but they have always had that wonky "go to sleep" issue and they often need to be reset. Plus, their sound file for diesel just doesn't sound anything like a EMD nor an Alco. That said, they originated many years ago in the infancy of DCC and were life changing. It's just that nowadays they're a dinosaur. Just my $.02

Regards, Chris

Arto, I don't think the wire conditions you mention have anything to do with the problem.  Hate to bring a negative comment, but those old QSI decoders are junk (ask me how I know). I would bite the bullet and just replace it with a current manufactuers' decoder (Tsunami, LokSound, TCS)

Regards, Chris

Another QSI hater.
 
It wounds my heart with a monotonous languor.  Smile, Wink & Grin
 
I love QSI decoders in spite of their quirkiness.

This is sort of related to my QSI post.

I moved on to speed match three BLI E8 Pragon2 locos.

I've only been changing CV5 values. On several occasions now, somehow, CV1 (loco address) seems to be changing to some random value and therefore changing the locomotive's address.

SO, I'm wondering if the wire gauge I'm using to go from The DigiTrax PR3 or LokProgrammer the Programming Track is too small. For sake of convenience I'm temporarily using a couple of sections of Bachmann E-Z Track with one of those "grade crossing/connector" track sections. The wire is Bachmann E-Z Track, about 10' long. Seems pretty thin. Using a wire gauge I'd say it's 26awg.

I think it's kind of weird that CV1 has changed "by itself" while changing only CV5, on two different locos, same brand, same model.
