Dear All,
in beginning 2018 i startet also to build up a train traking system by use of RFID. I also posponed my action however during my testing i have also seen the behaviour listed in previous reports with the cheap rdm6300.
At the end i choose a larger antenna to get a higher range. Together with an discrete 125kHz detekor ( own design) i was able to extend to a range of approximatly 6 cm (on single antennas) However this leads is the fact i did not decode the Tag ID itself, but this allows me to operate on higher train speed. Since i do not need the Train ID, it works fine for me.
Antenna side by side operation will disturbe each single system.To allow operating antenna side by side (see picture) the 125kHz Signal need to be in sync, therefore i use an external 125kHz Signal as master.
I did not notice any major impact in case the tag is placed below a 9V or 12V motor(i use 8khz PWM to control the motor).
regards
