Check the listing for details. AM BDCST. DUAL COIL CRYSTAL RADIO RECEIVER W/HEADSET & TUNABLE TRAP FOR BCI. Condition: New. Listed at 122.50 USD. I make these from scratch, so please allow about 8 to 10 days for shipment, once purchased. Most any reasonable color is possible. If you have a preference, please inquire when purchasing. I've made several versions of this radio over time. You'll receive the one in the first photo, with your choice of color. Please inquire when ordering. This is a little overkill for a crystal radio receiver, but I wanted something that was a good performer. We have a local 50K watt AM station that renders a simple crystal set pretty useless without a tunable trap. So this set has a tunable trap control right on the front panel that covers the full am spectrum, just in case you have a similar situation with BCI where you live. I find that even though our local station is really powerful and pretty invasive, the trap will null out better than 95% of the interference, virtually eliminating the issue. All this is possible with one jumbo size plug-in coil form that I have custom made for this radio. The color of the magnet wire may vary, depending on what I have in stock, so it could be red, green or copper color. The circuit uses two L/C tuned circuits, which are paralleled to one front panel control, using a dual 265pf capacitor. A separate control adjusts the antenna coupling, and yet a third control adjusts for elimination of BCI. Headphone volume is quite adequate for most medium power am stations, with good selectivity that is made possible by the dual tuned circuit, along with the adjustable BCI trap. You will receive a impedance Piezo Headset like the one in the photo, which is included in the price. The size of the radio chassis is about 6.5 x 4 x 2 3/8ths inches.
