I have a surplus dealer leaflet that sez you can tweak the final and cover 40 meters as well. However the rec tuning is pretty "fast" as is. It's almost like a toy radio in its simplicity.

I had the "Swedish set" and maybe the most complete 288 set around, let my brother sell them for me. I sort of regret that now, but i tend to regret selling anything that is "cool". I do have enough splendiforous projects left and i do absolutely not want to end up leaving a huge mess like the deceased owners of the irrationally huge estates whose sales i attended in 2024.
