This project is a USB Audio, Serial and PTT interface for rigs that does not directly support digital modes provided by applications such as FLDIGI, WSJT-X and JS8CALL. Plug these interface devices into your Windows or Linux laptop or Raspbian Raspberry Pi and you can send and receive digital tones to/from your rig and automate the frequency and mode control and PTT control.

A basic introductionto APRS on HF Bands for radioamateurs and how to setup an APRS tracker using Argent Data Systems T3 Mini TNC device, configured and assemble ready for portable operations.
For low voltage applications, like cathode bypass capacitors, most vintage types have an axial configuration, which is less common today but still available. Electrolytic power supply caps likely constitute the single worst liability in old audio, radio and test equipment. Rap about Electrolytics, Reforming, Chassis-Mount Replacements, Under-Chassis Installation, Rebuilding Capacitors
A home made Beverage system for portable use. The goal was to switch between 4 single Beverage antennas without interfering on the other receiving stations.
