9 band vertical HF antenna
May be it sounds crazy, but this antenna realization is my former idea of using any random wire as HF multiband

27m Titanex vertical
The antenna tuning unit used with this 27m Titanex vertical was originally designed to operate on 40, 80 and 160m

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'

DHD Double Half Delta

DHD Double Half Delta This is a dhd double half delta in theory it should return a low signal but with a good s - n ratio roughly like a beverage

Visual CW Tuning Indicator

Visual CW Tuning Indicator Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs an awkward and time-consuming procedure
