Interfaccia isolata per 2 radio e PC
Il circuito e piuttosto semplice, molto simile a quello di molte interfacce optoisolate

Interfaccia radio PC per emissioni digitali
Le applicazioni radioamatoriali che consideriamo sono implementate sulla base del protocollo dicomunicazione AX.25 ed utilizzano toni audio per codificare e trasmettere on air le sequenze di bit

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

Convert ADIF to Cabrillo Format

Convert ADIF to Cabrillo Format Have an ADIF file from amateur radio contesting, but the contest you want to enter wants a Cabrillo-formatted file? This is the tool that you need
