F4FDP - Jean-Luc - This is F4FDP's blog on Vox.

Adonis - Adonis microphones for amateur radio, and accessories, vox, double vox, voice memory, voice mixer

Wolphi-Link Android Smart phone to FT-817 857 897 interface Priority listing - Wolphi-Link is an Android Smartphone to Ham Radio interface. Wolphi-Link works with DroidSSTV, DroidPSK, DroidRTTY and Morse Decoder. It will work with radios which don't have a VOX.

QSK for the TL-922 and SB-220 mods - Beautifully constructed amplifiers. Unfortunately, are not suited for high speed T-R switching, a necessary attribute for operating AMTOR, QSK-CW, or SSB-VOX modes.

FT-817 ND Modifications - DRM reception / SDR output (IF 12 kHz), Using the internal VOX for the data jack, Connection of the mini speaker microfone ICOM HM-46

Radio Bahamas, ZNS - Info about the three AM BCB stations of ZNS (Zed-N-S), Radio Bahamas.

Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

Vox Recorder  ^pop - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists.

Audiocoreder - Audiocorder is a VOX program which allows your Macintosh to act as an audio recorder

Vox Actuated Recorder for Windows - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input.

SUPERVOX - S 300 - AM CW SSB linear amplifier for 160 80 and 40 meter band

A simple VOX circuit - Here is a 3 transistors 6 diodes circuit that is a Voice Operated Tx PTT control as well as an ANTI VOX circuit to stop mis-operation from Rx noise by G8MNY

A fool-proof VOX - A circuit which had been used in many other application before. The configuration described here is optimized for IPHONE/radio operation.
