It seems MTR5B is now upgraded as described in the store description (only assembled version not the kit.) I am glad the side tone issue, which I pointed out in the forum before, was fixed in the new verson along with the battery problem. I wonder if there are any ways to upgrade old version products. I am willing to pay for the upgrade if possible and reasonable. Any relevant information is appreciated. Thanks. de JG1GPY Takeshi Abe
