Reply to "How to run postwar, Lionel Legacy and some form of DCC on same track... and what to use options"

Thanks Sinclair

yes this is helpful.  I just read last night about Niel Young (I can just see him coming up with rust never sleeps due to cleaning his track constantly) helping to get TMCC created along with some silicon valley pals and that it radiates to antennas in the KHz frequency range.  It would appear the outside rail would comprise a loop antenna for circles of track and just a lot random antennas for more complex stuff.  Cannot imagine that it is tremendously efficient or resonant.  Or could think of it as the locomotive antenna in the (reactive) near field of the current carrying modulated TMCC outer rail.   Probably more reasonable physically.  That makes sense why DCC would interfere with TMCC radiatio as the DCC is a strong DC signal (as far as us radio frequency guys are concerned) interferes with the TMCC low frequency radiated signal.  The Digital modulation for DCC is probably not far off from the TMCC band and the track carrying the DCC radiates just as well (which is not well) as the TMCC signal.  Cool system.

It does look like to run the post war type engines I need to have power blocks or convert them the some form of TMCC or DCC but perhaps as you say best not the mix those two.

Thanks!
