Usually a WSPR station contains a computer and a transceiver, but it is also possible to build very simple beacon transmitters with little effort. Having the need to measure milliwatt powers from my WSPR transceiver, I decided to build a simple measurement device that would indicate power up to 5W. You can search by specification using our parametric search tool, download datasheets and get quotations. In the past I have stated several times on the Yahoo Group that I would not be adding FM to the mcHF (a completely stand-alone QRP SDR HF transceiver) any time soon, mostly because I was quite certain that there was simply not enough processor horsepower to do it properly, but quite recently I (sort of) got obsessed with making it work, going from "0 to 60" in just a few evenings of code. Output power. Joe Taylor, K1JT. For example a simple WSPR beacon can be built using the Si 570. A few days ago we posted about RpiTx, a piece of software that allows you to turn your Raspberry Pi into a multi purpose transmitter by modulating the output on one of the GPIO pins.
