7 transistor 7 MHz 700mW FT8 and JS8 DSB transceiver
Super simple. Direct conversion/DSB for two popular digital modes on 7 MHz. Under 1w output but gets good results. A lot of similarities to my Beach 40 DSB rig. Video discusses QRP PA design so could be worth watching even if you're not into digital modes.
PS: Into low power amateur radio? Minimum QRP is the top-selling manual on the equipment, antennas, operating and strategy of successful QRP operating. It's available for under $US 5 each in electronic form. Or you can get a paperback version. Visit VK3YE Radio Books to find out more.
