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...

“100 Watt” Dummy Load

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...

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...
