Various ramblings – Electronics, Radio, 3D Printing & CNC
While working on a small PIC project as an addition to a larger project (a JUMA RX1 DDS LSB/CW receiver) I had the displeasure of using Microchip’s IDE MPLAB. MPLAB looks like it was designed in the mid-90’s, and while it does let you piece together code and compile it into PIC compatible hex, it’s not the most user friendly...
With the case finished, there was only one thing left to do… Jam the radio in the case and make it work! The digital dial kit and main board are secured to the case using brass stand offs (used for securing motherboards in PC cases), once cleaned up they solder rather nicely to the PCB cladding. The lid is secured...
Being my first transceiver, I really wanted to make it my own (well, as much as I could with a kit…). I had seen many radios built into cases made from FR4 fibreglass PCB material, and thought I might have a go at doing my own. Quite a simple process but it would have been much easier if I had...
To align my SW-40 transceiver I needed to use a dummy load, something I didn’t yet have. The dummy load I bodged together in a hurry was 2 x 0.5 watt 100 ohm resistors in parallel on a BNC chasis connector. It worked, but got warm enough to discolour the resistors enough to make reading the values tricky. I had...
My first transceiver kit, a nice little radio with great instructions and is easy to build. I built this board over 2 nights, about 4-5 hours in total. While researching and ordering this kit I was still in the process of getting my foundation license, and not long after getting the kit in the mail I stumbled onto a small...
My first project for the radio section of my website, and a nice easy one at that! This is a loaded dipole for the 40m/7MHz band, this design was chosen mainly due to the fact I don’t have enough room to hang a full size dipole. I created the design using a great calculator I found here. There are many great...
