Law enforcement confirms a child has been abducted. Law enforcement believes the circumstances surrounding the abduction indicate that the child is in danger of serious bodily harm or death.

Encyclopedia Encyclopedia : M : MO : MOR : Morse code Morse code is a method for transmitting information, using standardized sequences of short and long marks or pulses — commonly known as "dots" and "dashes" — for the letters, numerals, punctuation and special characters of a message.

The WBR – A Simple High Performance Regen Receiver for 40M by N1BYT EDIT (July 26th 2014) – If you’re thinking of building the WBR, I strongly suggest you check out my most recent build here, which incorporates a mod suggested by LA3PNA, and a different configuration for the AF amp that I think provides nicer sounding audio. The full schematic is published there also. A few weeks ago when a sizable order of parts arrived from Dan’s Small Parts And Kits, the plan was to use them (along with the parts from a few smaller orders from kitsandparts.com and Mouser) as the basis for some fun home-brew projects. I got my feet wet by building some small circuits Manhattan style – an audio filter and RF preamp for my VRX-1 DC receiver, and a crystal oscillator in an Altoids tin to check out the MeSQUARES I had just received from QRPMe.
