Summary

The XVTR (transverter) button in the spectrum overlay band menu needs its own sub-menu, similar to how the Band button opens a grid of band selections. The XVTR sub-menu should list available transverter bands/profiles.

Currently the XVTR button is present in the band grid but disabled as a placeholder.

Location

• src/gui/SpectrumOverlayMenu.cpp — band panel grid, XVTR entry

Tasks

• Research SmartSDR's XVTR sub-menu layout and available transverter band options
• Implement XVTR sub-panel (opens from XVTR button in band grid)
• Wire transverter band selection to slice tuning
