Adjustable coil for mediumwave (MW) DIY detector radio

thingiverse

This is an all-adjustable coil made specifically for a medium-wave DIY detector radio project.\nBuilding this radio will require about 30 turns to detect most popular European stations, producing an impedance of approximately 50-180 uH.\nThe radio operates within a frequency range spanning roughly 550kHz up to 1100kHz. If you're captivated by this invention, you might want to take on the task of creating one for yourself using these guidelines:\n\nhttp://www.thingiverse.com/thing:425768 Building this medium-wave DIY detector radio is possible with minimal materials and requires these parts to create the simplest version - the detector: 1.\nThe main part necessary here, you need printed coil housing with handle attached for ferrite rod.\nFerrite Rod-2cm-long-with Two Flat Side \nof 0.15 inches of a German Type\nAAGermanium type Diode-1-\nin the simple design AA-112-or Similar\nceramic capacitor type: P F-47, C E- crystal Ear piece-(with an impedance Of abt High Impedance).0 of 2000Ohm.2 laquered copper wire with 0.04 inch diameter \of approx twenty-meter-for Antenna- Ten-Meter ground-20 Connection
