Today we’re going to talk about JS8Call. What’s JS8Call? If you’re a ham radio operator on HF, then you likely know all about FT8 and what it’s done for (or to, depending on your perspective…) amateur radio. It’s made a simple 5 watt QRP station capable of truly worldwide contacts! Here in Washington State, I …

As shown in A Previous Post, the QRP Labs QSX is on its way. It’s a SDR based all mode HF rig, 80m through 10m. It’ll be digital ready, too which is very cool! Recently we looked at what it’s going to take to build the QSX, and in this post we’re going to actually start …

Recently on HackADay.com there was an article called “FT8: SAVING HAM RADIO OR KILLING IT?” which drew fire from some and praise from others. The article title itself was a little click-bait-y but justifiable. According to the source article over at flexradio.com FT8 lovers and haters are split almost 50/50. Some say its awful because FT8 …

Yes, you read the title right- 9800 miles (15772km) on 200mw of power using WSPR. Read on to find out how this was done, and why it was even possible to begin with. Equipment used The equipment is simple. At the top is my QRP Labs U3S as shown in a previous post, the Bread …

In September of 2017 I built a QRP Labs U3S and posted my initial review of it on This Blog. That was over a year ago though, and since then a lot has changed. So lets catch up and re-review the U3S and talk about what it can do, and how you can get the …

In 2017, QRP Labs changed the QRP kit landscape when they released the QCX, a high performance single band QRP CW transceiver. For $49 a person can have a self aligning transceiver packed with features. Many wondered: will they follow up with a SSB kit? The answer of course is yes. But it’s going to …

I’ve written about putting together a dual band BITX40 in the past and the methods I used had varying success. The idea was to augment the built in filters with switched in/out add-on filters from QRP-Labs. This is a sound idea, but the layout of Low Pass Filter on the BITX40 really didn’t allow it …

Howdy folks! In this video we compare the $10 QRP Antenna pole that we previously reviewed and the 31′ Fiberglass Jackite pole. They both have their uses, but which one is the clear winner? Or IS there a clear winner? The Jackite pole is great because it’s sturdy, tall, and very high quality. The QRP antenna …

Many electronics experimenters and builders take the lowly 7805 regulator for granted, and we pop it in a circuit without a second thought and move along. But for beginners who are wondering how to power their Arduino or other 5 volt project (such as the QRP Labs U3S) from a 12v-13.8v power supply, the 7805 …
