Arduino: 1-Watt 2m Transmitter with RF Signal Generator abram, September 15, 2021October 19, 2021 Since I do a lot of RF projects, I wanted to see if I could make a 2m power amplifier using a minimal set of components. I have a number of BS170 MOSFET transistors that I’ve used for dozens of applications over the years from guitar pedal pre-amps to digital… Continue Reading
2m AM Exciter abram, March 18, 2018April 9, 2018 Here’s a project that I’ve been working on for a class recently. This is a very basic 2m AM Transmitter that operates from 144.25 to 144.31 MHz. It does put out a low powered RF signal (around 5 mW PEP) that has been copied over 1 mile from the transmitter…. Continue Reading
