Homebrew QRP 7 MHz SSB transceiver: circuit anatomy
A look at the circuit of a basic 7 MHz SSB transceiver and a description of some of the finer points. The circuit presented is an amalgamation of ideas from designs like the following:

Sometimes you plan to do one type of radio activity but end up doing something else. This video is where I go portable and end up working 80m slow scan TV in the middle of the day.

Are you hearing signals that you shouldn't in the HF amateur bands? No, it may not be because they're transmitting where they shouldn't. And neither might it be your equipment. Your antenna could instead be the problem.
Watch as I fault find and fix a problem with my G5RV antenna at home. The repair also made the antenna behave as it should and removed the risk of it generating harmonics on transmit.

DRONE
drone-machine-annoying-noise-maker
A novelty project that serves no useful purpose and a break from the usual radio stuff on here. It makes various beat noises and rhythms.
There's six audio oscillators - two low frequency and four high frequency. The two low frequency oscillators can trigger two of the high frequency oscillators, making some interesting effects possible. A light dependent resistor and touch plates allow even more variations.
Machines like this tend to polarise people - they're either loved or hated. Some like the lifelike rhythms or buzzes created, while others dismiss the output as discordant cacophany that is not music.
In case anyone is wondering this machine is not very original and I took some short cuts. There's numerous circuits for drone machines and simple synthesisers on the web and being audio are easier to get going first time than radio gear. And as shown in the video it's definitely worthwhile having the function of LF frequency oscillators triggering HF oscillators.
