TheXR2211is a modem on a chip and would make a nice audio frequency to digital data converter. It would accept either audio from a radio or audio from the wire line with some clamping Zener diodes. For better sensitivity when working with a radio link where there's a lot of noise a ...

General Radio by James Kilton Clapp Clapp invented the Clapp oscillator which uses a capacitor in series with an inductor (or crystal) to allow adjusting the frequency (Wiki). Most of these patent numbers appear in the manual for the GR 1100-A Frequency Standards (Radio Nerds) or the ...
Radio Frequency IDentification (Wiki: RFID) is different than anti shoplifting tags (Wiki: Security Tag). The idea with a security tag is to be able to detect it electronically if it is active. When you purchase a product as part of the check out process the clerk disables the tag so th...

The desired loop would be 1.5 mH for WWVB and the cap would be 4.7 nF with a Q of 100. To get the above coil down to 1.5 mH would require removing a lot of turns which would reduce it's series resistance increasing the Q, probably to way over 100. Then either a fixed resistor ...
