Although UK dealers are happy to take a deposit, I am not aware of a "final" (initial!) price or of any shipments. Maybe the design is still be optimised? I would hope that 5MHz is covered as standard as there will be a worldwide allocation (in most countries) from 2017 and some European nations have contiguous allocations of up to 150kHz I believe. Maybe they are looking at the FT991 to see if there are any bands/features that can/should be added?
Personally, I hope they release the 10W version in Europe as well as Japan. This would be a fine successor to the IC703. I'd buy one of these. Buy the 100W version? Probably not.
It is a pity 472kHz TX is not included in any Japanese (any?) transceivers. I guess this design would stretch the PA and ATU designs too far.
