QRPGuys No Tune End Fed Half Wave

About a year ago, I bought a few end fed half wave antenna kits from the QRPGuys. The No Tune End Fed Half Wave is of those that I got out of curiosity. The fact that there is no tuner required seemed intriguing. Basically, I’m skeptical so I’m going to build this one and try […]

5Watter Organic Transceiver Build Phase 3: Keyer and Keying Sections

This particular block should be straightforward. Basically, Diz’s kit ships with a programmed IC for using with a paddle. I believe that we will also be installing the keying switching transistors as well in this section. Components J4 – command button J5 – paddle jack J10 – speed control potentiometer (10k linear recommended; not included) […]

5Watter Organic Transceiver Build Phase 2: Audio Amplifier and AGC

Last time around, I built the power supply and had an absolute blast discovering why components were placed in their particular way. This time, I’ll be building up the audio amplifier section while performing research as I did in Phase 1. In general, this section revolves around placing an LM386, the requisite components that make […]

5Watter Organic Transceiver Build Phase 1: Power Supply

When building the 5Watter by W8DIZ, K7QO recommends building the power supply first as a troubleshooting measure. If the voltage regulators are installed and giving correct voltages, then you’ve eliminated one potential problem down the line. That, and it is difficult to determine whether everything else is working correctly if you can’t feed power to […]

A 5Watter Organic Transceiver Build: Introduction

When I first began my ham radio career some seven years ago, I was immediately drawn to kit building. One of the first kits that I discovered was the 1Watter, offered by Kits and Parts. I held off too long on getting that particular kit because of the small SMD parts and the lack of […]

SMD Soldering Practice: Basic FM Receiver

A few days ago, I received a 5Watter kit from Diz, W8DIZ. I knew that it would contain some small parts but they were even smaller than I imagined. In preparation for soldering smaller and smaller components, I decided that a lower cost kit would offer the practice necessary to solder these small parts. While […]

The 4SQRP Hi-Per-Mite CW Audio Filter

The FT-817/818 has been in production for over 20 years and now that I own one, it is easy to see why. It is a fun radio to operate and fits a lot in a small package. There’s really just one thing that I don’t like about it: the wideness of its filtering can make […]

The QCX

One of my favorite radios in the shack is the QCX, a QRP kit offered by qrp-labs.com. While the QCX has been in production since 2017, the 2020 updated version featured a nice, tailor made case (optional, but highly recommended) and a pcb which offered a more spaced out design for electronic components. These updates […]
