For FrequencyCast show 106, Kelly and Pete look at using a 3D printer to print more printers, plans from BT to buy back o2, and our experiences at a local Raspberry Jam. We also look at the world of shortwave and numbers stations, look at possible Freeview changes, and see what EE and Vodafone are up to with digital TV.
