Andy (G7UHN) over at SWLing Post has written an article detailing the build of his genius companion control display for the Yaesu FT-817 transceiver: Like so many I love getting out portable with my FT-817 but I do seem to spend so much of my operating time fiddling through the soft-keys because my most used […]

Shirt-pocket SSB transceiver
Peter (DK7IH) blogged about his 14MHz shirt-pocket SSB transceiver.
An Isolated RS-422 / RS-485 Shield for the Automation Direct P1AM-100 Open-Source PLC
Glen @ bikerglen.com writes: The RS-422 / RS-485 shield is an open source shield designed to add RS-422 and RS-485 communication capabilities to the ProductivityOpen family of open-source programmable logic controllers (PLC’s) from Automation Direct. It’s loosely based on the Arduino MKR RS-485 shield but updated to use an ADM2582E 3.3 V isolated RS-485 transceiver […]
N6QW Heathkit SSB transceiver
Pete Juliano, N6QW, has a nice build log on his newest version Heathkit 40M SSB Transceiver: What are you thinking — I am not trying to break any world record? My XYL asked me that question today — why are you building another rig? Followed up by a snide comment that I had so many […]
Simpleceiver Plus version 2 SSB transceiver
An update on Pete Juliano’s (N6QW) Simpleceiver project we covered previously: Version 2 — What is it? V2.0 is the Simpleceiver Plus SSB Transceiver Architecture with the following changes: A GRQP Club 9.0 MHz Crystal Filter is used in place of the homebrew 12.096 Four Pole Filter. This gives the advantage of acquiring the matching […]
Shirt Pocket Transceiver with the Si5351 and OLED
Pete Juliano’s (N6QW) Shirt Pocket Transceiver with the Si5351 and OLED display: In 2011 I fulfilled a dream of building a shirt pocket sized QRP SSB transceiver. Well actually I built two of them and the second was a diminutive 2″ X 4″ X 2″. Both used through hole components –so no cheating with SMD. […]
A new transceiver at N6QW, part 2
Pete Juliano, N6QW, has been working on a transceiver project. He writes: Today we complete most of the mechanical work and the only item remaining is the RC Filter to turn the Square Waves into Sine Waves for the tune signal. We have had it on the air in the current box as you always […]
DIY RF Transceiver using MRF49XA and AT90USB162
William Dillon has posted his initial work on a prototype USB RF data packet Transceiver dongle using the MRF49XA and an Atmel AT90USB162 micro controller. He embarked on a journey exploring the development of packet formats and protocols, as well as types of error correction. This open source project’s details, code links, schematic and photos […]
DIY wireless data transceiver
Build your own wireless transceiver: Have you ever wanted to send data from a sensor or project wirelessly? This simple circuit allows you to build your own wireless transceiver using two ICs, a transistor, and two resistors. The IC is from Melexis and uses On-Off Keying modulation and can be battery powered. Via Electronics Lab.
Portable software defined transceiver: Power amplifier
Jason has been working on a portable software defined transceiver design for the past year. Every day this week he’ll discuss a different part of the hardware in a series of guest posts. You can chat with the designer in the forum. Today’s post is about the power amplifier. Since this project is designed for […]
