An interesting home built 3 valve radio from the late 20's/early 30's. I still can't get my head round that's nearly 100 years ago. Uses the amazingly titled Igranic "What are the wild waves saying" basket weave coils as LW/MW switchable TRF front end and the centre one as the regeneration "tickler". Just needed a few tweaks and a new power supply to remove the battery requirement. It actually still has a wireless licence from the 30's stuck inside the lid.
