A Java multiplatform application used to find EEPROM locations for different radio settings. a very simple to use multi-platform Java application which can be used to find EEPROM locations for different transceiver settings. This information can then be used to send the right CAT commands to configure the radio remotely. Use this application on your own risk.

Antuino is an accurate instrument that can be used in the field to measure SWR, field strength, modulation, etc. In the lab, it can be used to sweep filters, measure gain, distortion, frequency response, etc. It works upto 150 Mhz. On the third harmonic, it is usable on 435 Mhz band as well (with reduced sensitivity).

The TECLA Thirty, an early wireless age crystal set, is featured among a gallery of over 100 collectible headphones, with detailed close-up photos of vintage models. Several pages offer vintage headphones for sale, including Brandes, Baldwin, and Western Electric, suitable for crystal set use or collecting. Construction details are provided for a reproduction KILBOURNE AND CLARKE crystal set, built with vintage 1920s parts and featuring a miniature variable condenser for fine tuning. The resource also presents a project for a simple crystal radio and a 1-tube amplifier, complete with a schematic and component diagram, suitable for driving a horn speaker or amplifying weak signals for headphones. Instructions for mounting argentiferous galena detector crystals are included, along with information on MRL Handbooks covering crystal detectors and modern diodes. Additional projects include a 2A3 single-ended triode tube amplifier and two stereo tube amps using 12AX7, 6V6, 5Y3G, 6SN7, VT-25, and 5U4G tubes.
