Those are the servos I am using! A hex frog juicer is a piece of electronic kit that detects a short circuit in the frog and switch blade of a turnout as it changes position and very very quickly reverses the polarity of the frog and blade. I am talking DCC here, they do not operate on DC. The changeover takes place within a few microseconds and is undetectable by the DCC system so no stuttering of the locos or resets occur. See http://tamvalleydepot.com/products/dccfrogjuicers.html An American product available from Digitrains amongst others. Colin

I am using a Megapoints controller with a DCC interface and the electronics, set up and use have been reliable so far BUT the constant ticking of the servos is very annoying. At a show it wouldn't be noticeable but in the relative quiet of the Railway Room it certainly is. I asked Dave and he said buzzing could be fixed but the ticking was common to all servos. I gave up grovelling under the baseboard trying to set up micro-switches on blocks of wood to work reliably and not cause the servo to buzz. Invested in a hex frog juicer and couldn't be happier with the result; much easier to install and no adjustment needed; if a tad more expensive! :-) Any one got any suggestions or ideas about removing servo tick? I guess they are slightly adjusting their position all the time, well every few 10s of seconds or so. Colin in Lindum

Did you ever get a reply or sort this problem out? I have just put my 2nd. 4 CEP on the track and it has the same problem. DCC sound fitted green unit with the small yellow warning panels. My other unit fitted with the same sound decoder works just fine.
