I was going to suggest to our club that we take advantage of the offer to upgrade our RC2 to the new RC4 Decoder . Glad I didn't as we have a lot of MRT Transponders in use that it seems don't work with the new decoder.
Sounds like there will be some clubs out there who took advantage of the offer and will have some unhappy members when they realise their MRT transponders will be useless. Can't even resort back to their old decoder if you took advantage of the deal as you had to send them your old decoder as a trade in.
Glad we didn't jump the gun!
