    You can't do it using SmartRF studio. Soldering iron will be better tool :) Note that antenna matching network, balun and antenna is different for each version. SLAU292 have all the BOMs, circuits and board layouts - you can look for (electronic) differences yourself.

    As Ilmars pointed out, the external circuitry for 433 and 868MHz is different. It is even more different than just different part values in the balun.

    You can use an 868MHz transceiver and a 433MHz transceiver, program them for transparency mode and connect them. So anything received on 868MHz will be sent out to 433MHz and back. So the 433MHz endpoint can communicate with the 868Mhz Chronos. However, it would be easier to buy a 433MHz Chronos instead :)
