Mylaps transponder missing laps

Mylaps transponder missing laps
I have a fairly new (7-8 race days) mylaps 3 wire transponder that will occasionally miss a lap. It's happened in two different cars now. Today it was in my 1/12 scale where I initially had it mounted on its side stuck to my servo. It missed 2 laps during my first qualifier, so I moved it to the top of my servo mounted flat. In the main it missed another lap. Will the servo cause interference with the signal of the transponder, or is it something I should contact mylaps about?

RTFM?
The transponder need to be mounted flat because then it will transmit its signal up and down.

Yes, mounting ontop of the servo means its mounted flat, but if the timing loop is under the track, it has to go through a 2mm thick aluminum chassis and all the gears and motor and PCB of the servo, and maybe another 2mm of CF before the signal can be picked up
Mount off to the side of the chassis on a piece of scrap lexan, giving it the best possible chance of sending its signal and see if your loosing laps again. Contact the manufacture of it does indeed doesnt count all the laps

That would make sense, but I forgot to mention that our loop is above the track, that why I figured putting it on top of the servo might work since it would be closer to the wire. I'll try moving it away from the servo next time and see if that makes a difference.

Possible issues, from my experience, when mounting transponders:
-avoid mounting on metal or carbon,avoid mounting on servos or close to any electronics
-mount it horizontally. Plenty of guys will tell you "theirs works good vertically", but that's no reason for you to mount it that way.
-this is mostly for older big ones, but check the wires exiting the case. This is the cause of 99% problems with the old ones, fix this by resoldering (plenty of how-to's on this forum) and you're good as new. I've fixed mine and still use to this day. Wish I could have done a cleaner job back then so it looks a bit nicer
Avoiding carbon and metal are small things but they can help. Horizontal placement is a must. Try and mount it on a piece of plastic, hanging from it, preferably away from other electronics. When you've fixed the issue, go to your timekeeper and check if the hits per second (or whatever it's called) is a healthy number.

Conducting materials close to an antenna can make the signal weak.

What version decoder does your track use?
Isn't the 3 wire only compatible with AMB 4.5 and newer?
I think you might need to get the 2 wire Hybrid if your track is using an older system.
I am running MRT transponders which work on all MyLaps systems up to AMB 4.4
I mount my transponder on top of the servo like this and the loop is buried under duct tape on the track, I have never missed a lap over the past 9+ years I've been racing with MRT transponders

We've had similar issues at out local track. The loop is mounted above the track and they move it around from road course to oval and if they don't get the loop back at the right height, it misses laps as yours does. The scoring system also can tell if your transponder has a weak/strong signal so the directer can adjust for this also. Gotta find that right spot for the loop and the signal.

1/12 .....
Did you power it from the receiver or from the battery?

There is a slight possibillity that the transponder is bad. Any possibillity you can read out the hit value and compare it with others?

Just throwing it out there. "Homemade" loops can cause issues as well. I've mounted my PTs, all versions, just about every way you're NOT suppose to without issue.
