Becoming a ham radio operator is a natural fit for anyone wanting to be self-sufficient. Here's how to get a ham radio license in the U.S.

My favorite ham activity is making contacts via satellites. Not only is there the romantic notion of sending messages into outer space, but you have to

Diana Eng shows how to make your own End-Fed Half-Wavelength Antenna (EFHWA) for portable radio operations.

Crosley Radio Corporation’s 1936 “WLW Model Super-Power Radio Receiver” Surpassing the Zenith Stratosphere turned into a bigger project than anyone had expected.

This Biophone-inspired* ham radio "go box" was a long-planned and often-delayed project. The box contains a small two-way radio and a battery, and by flipping a couple of switches, attaching a quick-connect antenna, and releasing a velcro strap on the microphone, I can be on the air in seconds. It first saw service during the 2018 Honolulu Marathon, operating for 13 hours at Net Control. I had it hooked up to an external battery and antenna. It worked very well. The box is a Nanuk 905. The radio is a Luiton LT-898UV 10 watt dual-band mobile. Internal power is from a 3.4 AH sealed lead-acid battery. A speaker with a cut-off switch and a headphone jack with volume control lets me use either or both without having to readjust the radio volume or unplug the headphone. It's roughly 10" x 12" x 6", and weighs about 9½ lbs. ------- *Biocom's Biophone 3502 was a paramedic telemetry radio made famous by the 1970s NBC TV series Emergency!, which portrayed the Los Angeles County Fire Department's paramedic program. Paramedics used the Biophone to communicate with and send EKGs to the supervising doctor at the hospital emergency department.

The aerial element and the coil are made from a single piece of 1.5mm welding (brazing) rod, and the dimensions are given in Figure . Wind the coil around a 4mm rod or the shank of a twist drill. The lower end is filed to a point and then soldered into the centre conductor of a 4-hole panel- mounting BNC socket. (Try to obtain a good-quality BNC socket with PTFE insulation – the insulation of cheaper sockets is easily damaged.) Trim the element to 427mm (top of element to top of coil) after the wire has been soldered to the socket. The base coil causes the aerial to be rather ‘whippy’, so a piece of 5mm plastic knitting needle can be cut to the length of the coil and then forced into it. The radials are made from four lengths of 3mm welding rod. These are bent and soldered into the four mounting holes of the socket, and then cut to the lengths shown in Figure . The aerial is made waterproof by enclosing it in a 22mm diameter PVC waste water pipe. It is ‘weldable’, and available at plumbers’ merchants, usually by the metre. A coupler is slotted to take the radials (Figure ). Filethe BNC socket as required, so that it slides inside the coupler until the radials poke out of the slots. Cut a length of plastic tubing which is 30mm longer than the aerial, and push it into the coupler. You will then need a plastic bung or screw-top to waterproof the top end.
