Simple 30 meter receiver low power qrss beacons and psk31
That is possible by using a low CW speed. QRS mean reduce your CW speed. With that extra S of QRSS they want to indicate that it is really a very low CW speed
Telephone Remote Control Project
Basically the interface allows me to dial my home phone number and connect my interface with a password after the answering machine answers
Tenner QRP 10m CW Transceiver
Small experimental CW 500mW transceiver using just 5 transistors
The flea a 40m minimalist transceiver
The transmitter is based in the old " Cubic Incher" by AE6C It runs very well. The receiver is really a new idea d>
