Hallo Mathew, I picked up on your reply to Thor- "Humidity does strange things to material that can absorb moisture and change to overall operating characteristics of a model layout". This has nothing to do with your original request in this forum request, but alows me to ask you about this humidity issue.
My system is based on a Märklin C track, Windigipet 2021.0b, CS3 and a PC. Two very active Windigipet friends have developed an alternative feedback system (20 units installed on my layout,) based on LocoNet and a DR5000 controller. There is an issue with the contact signal which is not that stable, the Windigipet FB software has the possibilty to lenghten this sampling time ( I hope this is the correct terminology ?) which does not seem to help. Isopropanol does improve matters slightly along with track wheel cleaning but the underlying issue still remains.
Is there a way in Windigipet to overcome this issue? and / or is this a straight humidity problem?
One last point, I have often seperately measured anything from 60v to 170v between the negative and positive side of my C track to EARTH which seems to be humidity related and the amount of layout track traffic. 18v between positive and negative supply remain unchanged. Is this a problem for the layout electronics? Märklin have effectively ignored my request for clarifiction on this issue.
I look forward to your reply with best regards, Dave Conner, Berlin.
