#hamchallenge week 48: Transmit a QRSS signal on the HF bands. For this one I used my fork of WsprryPi (https://git.fkurz.net/dj1yfk/WsprryPi) that was modified to send QRSS CW, on the same Raspberry Pi that runs my 30m grabber at SO5CW. The signal is well readable, but (unsurprisingly, because no antenna was connected to the transmitter) was not picked up by any other grabber. #HC48S @hamchallenge
