Hello,
I did a comparison between 6300 (that I have owned for more than four years) and my new PRO2 when used in SO2R contest operations.
I used the best configuration possibile for both the systems, so Flex 6300 is configured for N1MM while the PRO2 is configured for 5MContest.
Results are quite interesting, and open considerations and great expectations for the TCI protocol. Just think about audio and data stream implementation in the TCI and what it means in terms of flexybility and reliability.
