I've really been looking forward to this, I ordered mine earlier today. I'm going to use it with a Raspberry Pi 4B, USB sound card, and Gentoo Linux. Antenna will be a QRPGuys UnUnTenna Plus

I just ordered my QRPGuys DSB Digital Transceiver kit. Really looking forward to building this, should be fun for only $40. N1ESE

Gang, We are pleased to offer the QRPGuys DSB Digital Transceiver kit. It includes three easily changed FT8 band modules for 40/30/20m. The kit uses all thru hole components. Price is $40. We are

Terry, I'd sent that message to the group and CC to me. The link worked both ways here. I usually don't CC to me but wanted to check the link. Try this:

Good advice to stay away from strong solvents. Carb cleaner and brake cleaner are usually recycled solvent mixtures that can vary considerably from batch to batch. I restored about a dozen 5 tube

Before I invested too much time, I’d clean it up enough to power it up and see if it’s worth the effort. You’ll have bring it up slowly on a Variac to reform the power supply caps. Then I’d

OFF-TOPIC - Skip as you may wish. I've acquired a 1950s oscilloscope. The exterior is cleaning up nicely with Simple Green and a toothbrush. But the inside is baked-on dust and fluff. Compressed air

Thanks for the report Chuck, I'm really looking forward to this project. N1ESE

A Siglent SVA 1015X Spectrum & Vector Network Analyzer image sent to me by Ken, WA4MNT, shows that the second harmonic is down more than 50dB from the fundamental. This has got to be much better than

I built a beta version of the DSB transceiver, which will be available via the QRPGuys.com web page sometime in the near future upon arrival of parts. I built the kit according to the PDF from their

With the USB-C cable/charger bug on the pi 4, it has had me wondering how to power it properly from 12V. Anyone running their pi 4 from 12V and mind sharing with me how. I haven't bought a pi 4 yet,

I don't know how many readers here are into scratch - build. Anyway, I can't just toss these. I have 2 "wideband amplifier boards" from Northern 550 hybrid SSB boat radio. 4.5 x 2.5 inches, 5
