Hi Ian: I also have a Kent Paddle that I love dearly. I replaced the Vibroplex paddle about two years ago and this is the best one I have ever had among many including the Jones, Bencher, etc. I have both an ICOM 706 Mk ii(g) and an ICOM 746 and it works well with both. I don't know what mode Iambic the 706 is though but thought I would comment on the Kent Product. 73's de Stan W5ZF No. 6183
