When I read that MRC was responsible for the decoder in the Genesis Challenger, I cringed - MRC's own cheapie sound decoders have generally received unfavorable reviews. So, I was curious to know if they used a stock MRC sound decoder, or if MRC made improvements for Athearn?

The logivc goes that the Challenger you have in your hot littles is the announced (but never delivered) Roco Challenger, and as its normal decoder supplier (Lenz) hasn't as yet done sound - although interestingly, their newest decoder offers a SUSI interface for sound, that's another story - then they turned to ESU.
Our group here has several ESU-equipped loco's, they are impressive (except for the whistle). ESU decoders come equipped with speaker and baffle, their chuff is as good as I've heard, and they are easily installed. One of our members put one in a Bachmann K4, and again, apart from that woeful whistle, it is quite an effective combo. Incidentally, I understand the latest version does make the whistle playable, but we're still waiting for one to try out.

You're right, we finally got hold of one to look at, its clearly an MRC. And sounds crappy. A smear on what is an otherwise fine model. Oh well, mark it "Upgrade With Tsunami". Apologies to those fine folk at ESU who feel I may have slighted their decoders.
