This appears to be a mystery radio. Perhaps I was the only one foolish enough to buy one! Hi Hi!

Sorry I don't have one to play with but...yaesu always uses the jump pads next to the if chip..The ft 1dr is just a vx 8 revamped so would assume the 400 is just a revamped ft 350..

Just locate the if ic and look for the solder pad jumpers n carefully remove one at a time "normally the front one " and reset radio and try.

If it doesn't work ...simply reinstall part.

I never waited for mods to show up..yaesu methods doesn't change .

And of course this would be for emergency purposes only or simple general knowledge ."disclaimer".

Thanks for the input! I'd really like to know what Yaesu has to say.
