DIGIVOX-2 INTERFACE FOR DIGITAL BROADCASTING
DIGIVOX-2 is a passive, power-independent system that connects a computer to a radio.
It is designed for digital modes that use the sound card as a modem.
Interface features:
allows you to connectany VHF/UHF or KF radio with a PC
works very well with handheld radios, e.g. Baofeng
provides full and complete galvanic separation between radio and computer (600V)
does not require external power supply
you don't need a serial or USB port. Connection to the computer is only through the audio I/O of the sound
card
works with most computer programs designed to broadcast digital Packet,PSK31, RTTY, SSTV, FAX, etc.
works very well with the Winlink Ekspress program (e-mail using radio waves), which allows you to send
messages in the absence of internet using a gateway (e.g. Poznan SR3WLK) or directly (peer -to-peer)
Schematic diagram:
When a sound signal of appropriate amplitude appears on the audio output of the sound card (SP),
the Q1 transistor is opened, causing the DIGIVOX-2 PTT output to short to ground.
