So I downloaded JMRI and I have the computer interface cable. I am able to operate my locomotive through JMRI(I don't need to do that though), but I am unable to program on the main. I do not have a programming track. I could build a program track pretty easy, but is there any way to get this thing to program on the main? I keep getting error 306 when I try to write CV's and I can not read CV's at all. When I dont get error 306 using the 'write' tab, JMRI says 'ok', but nothing happens. Again, using MRC prodigy express as my DCC system.

I have an older Stewart F7 unit with a Kato drive. I recently did some servicing on the unit and after I reassembled the unit, I could hear a chugging noise coming from it (assuming it's an issue with one of the gear boxes). I took it apart again and ran it without the shell after inspecting the mechanism (didn't see anything wrong with the mechanism. Motor runs fine) and the noise was still present along with the unit slowing down slightly on one of my curves (22" radius) after minutes of running.

I recently purchased my first sound equipped locomotive with LokSound.  I like it very much and I am considering converting my fleet to ESU decoders.  I had considered mixing Loksounds and LokPilots in my consists to save money but I have read  that doesn't work very well.  Is it possible to mix these two types in a consist without too much trouble?
