Smoother tuning on the DX-392 and ATS818CS receiver
The rough tuning of the DX392 made it a pain to use when manually tuning the shortwave or amateur bands. The problem is the receiver is designed to mute between frequency steps. The modification described cuts a circuit board track to remove the mute and make tuning easier. It applies to the DX392/ATS818CS (ie the unit with the tape recorder). If you have the unit without the tape then refer to W9JES mods below.

PEDES
pedestrian-mobile-hf-antenna
A look at a hand-carried antenna for pedestrian mobile operation between 7 and 28 MHz. It is similar to the commercially-available 'Miracle Whip'.
Efficiency is low but solid interstate SSB contacts (up to about 1000km) can still be made on 7 MHz. Efficiency is better on 14 MHz with the best DX to date being Antarctica. A beachside location is an advantage.

SUPER
super-cheap-single-pole-beam-for-21-mhz
Beams can be heavy and bulky so are rarely used by HF portable operators. But not this one! Described is a simple vertically polarised beam for 21 MHz. With a quick to rotate wire reflector and easily-fed off-centre driven element.
Thanks to Nik VK3ZK for the test.

TUTOR
tutorial-demonstrating-capacitance
Explaining resistance, capacitance, inductance and reactance. Testing the reactance of capacitors and inductors, I explain how it changes with applied frequency. I'm using Peak Electronic Design's LCR45 LCR meter.
Other topics covered include resistive attenuators, complex impedances, low pass filters, high pass filters and tuned circuits. Don't let that scare you - it's kept as simple as possible.

Using two cheap Chinese handhelds (Baofeng UV82) to work through the AO91 amateur satellite. Their performance is marginal for this application. But if you pick a high pass, operate out in the open and choose a time when there's not many others on then you may make contacts.

A DRO

What happens when you connect the audio output of a drone machine to the video input of a TV? You get various effects on the screen. I explore this with various combinations of tones. Later I connect a radio to see how music can create patterns on the screen.
