The old AMB and MyLaps ones are all good David. It's just the MRT PTXs. MRT is able to send a signal the old decoders understand. The new decoders only see AMB signals and filter out most if not all of MRTs. As I used to buy bulk MRTs and offer them to those who needed them, I don't want to see anyone get stuck with them if the club goes to an RC4 decoder or RC3 upgrade to RC4 firmware.
