MMSSTV Yoniq... Is anyone using it?

[VK3LU]

I am using MMSSTV at the moment and have got it working great. I decided to have a go at its latest variation MMSSTV Yoniq, a Spanish creation. I have it working but I cannot get the band selection to work. It is a different approach to the original and it has me stumped. I am trying to control an IC7300
Is anyone using it and got the band selection working? How is it done?
