Simple Rtty codec system based on arduino e android A unit for receiving Rtty transmissions was created, the differences are essentially limited to the Arduino software used

All band dipole Mk2 The All Band HF Doublet is often referred to as a random length dipole as it is generally as long as the available space within reason, but here are a couple of limitations to the ultimate dipole length

160M 1/4 Wave Vertical 160m vertical antenna project. It is 100' of Rohn 25G and a 20' aluminum stinger. The base is made out of four 6' power line insulators sandwiched between two Rohn base plates. 7/8' stainless bolts hold the assembly together. 32 radials 50' long and 30 radials 100'
