Some days I find at my convenient store an aluminum form for baking bread. I have bought it. But I never bake bread with it I make a simple Three Bands Regenerative Receiver inside of the form. Nothing new it is in the schematic. It is widely known in Russia so called multivibrator regenerative receiver. Figure 1 shows schematic of the receiver.

Receiver works at the MW (0.63- 1.53- MHz), HF- I (1.8- 5.0- MHz), HF- II (5.0- 16.0- MHz). Inductors were made separately for each of the band. The inductors are sitting rather close to each other. For inductors L2 and L3 there are used form in 10- mm OD. The form has a trimming ferrite rod in 8- mm OD and 10- mm length. Inductor L1 is an inductor from my junk- box. Figure 2 shows i view of the receiver.
