 I recently purchased an old (1971) PFM sound system (Mark II?) that came with a Locomotive/Tender Module (LTM) and a reverb add-on system. I also have an MRC Command 2000 DCC system and several decoders, as well as a PFM Tenshodo Big Boy that says it's "PFM Sound Ready". What I'm wondering is if the PFM Sound System is compatible with (i.e. won't cause interference to) the DCC system? Installing the LTM is a fairly complicated process from what I've read and requires removal of the tender body from the frame (no big deal -- looks like 4 - 6 little screws). It also requires rewiring the power to or from the loco motor through various capacitors or diodes and the LTM module. I was thinking that while I'm going to all this trouble to install the sound module, perhaps I should also install a DCC receiver at the same time. Any thoughts or advice on this project would be much appreciated. Also, if anyone can tell me what the purpose of the reverb system is and if it is worthwhile adding, that would be a big help. Thanks, Bill V.
