Hi all,
I did not expect this resonance, but I'll try to explain and to be more precise
. Some statements at first:- I am not an electronic specialist; -results came from trial and error tests; I have a testbed for 60Hz Operation(230V 50Hz ->12V DC ->115V 60Hz)
I give you examples:
-conventional Trainsounds:Lionel 4-4-0 General-type Steam Locomotive ''Western & Atlantic from 2008: when operated with 60Hz you have steamsound and whistle, bell and crew dialogue are triggered by the whistle/bell button; when operated with 50Hz you have all at once together. It looks like that the power grid pulse of 60Hz or in Europe 50Hz is used to trigger anything in the electronics even in conventional mode. Operation in 50Hz seems to be regarded by electronics as pressing whistle/bell button.In this case I did not find a solution to overplay that. Only switch off or remove the sound board.
Trainsounds with TMCC: Lionel Trainsounds Caboose, Madison Trainsounds Baggage Car. when operated with 60Hz you have complete functionality, when operated with 50Hz you hear nothing. These cars have two devices: a receiver(not R2LC) and the Trainsounds board. As I understand the background, the TMCC signal uses the Zero passing of the 60Hz sine wave to get processed in the receiver and further on. To get the passing, a synchronization between the 60Hz pulse and the signal must occur(please, correct me , if I am wrong). That is done by a timer ? that is(was?) fixed for 60Hz . In one case I replaced the original receiver with an ERR minicommander, in the other case I replaced the original receiver with a receiver from a TMCC crane car that was prepared for 50Hz/60Hz operation. The original Trainsounds boards were not replaced in this case. As I operate only TMCC/Legacy, I did not performe a test in conventioal environment, I guess it would not work comparable to the TMCC cranes inoperables conventionally.. But It works in TMCC/Legacy 50Hz environment until today.
Early TMCC crane:comparable to the Trainsounds with TMCC. In 2008 Jon Z. changed the design of the receiver and a small chip applicable for 50Hz and 60Hz was introduced. I replaced some receivers in Europe to get the cranes operational in 50Hz. I have a TMCC crane in addition from early 2009 that is operational from the beginning with 50Hz.
By the way, early minicommanders were not operational in 50Hz. Jon Z. changed in about 2005/2006.
GRJ: I guess, you 'll come to York ? Then we can go in more details as I intend to visit .
NICK12DMC: I tried a small 60Hz fed layout for operation of the TMCC crane in the 60Hz version in parallel to and separated from the 50Hz layout, but that did not work proper. Signal reception was sometimes insufficient, so I try to have all TMCC/Legacy available for 50Hz.
As I stated I am not the electronic specialist, but I hope that helpes a little bit more
Regards
