Necessary was a laptop with software and a 2-meter band radio set with an antenna.
With this gear, Is was possible to transmit and receive both pictures and text by utilizing A.T.V..
Modulating and demodulation are done with the sound chip of the laptop.
We listened and sent from the 2 meters amateur band on one of the canals for using A.T.V..
When it was silent on the used frequency pictures were transmitted
controlled by the software. (similar to packet-radio.)
A.T.V. repeater coverage ensured a large range above the South West of the Netherlands.
It has been a nice and productive club meeting..
Till next time and 73 Evert.
The photograph above: A.T.V. applied for guarding the Veron bunker. Video camera with U.H.F. modulator/transmitter for the guarding of the shack.
We are using on the transmitter site, not a computer or laptop but instead the cheap electronics below
On the reception side, personal computer software takes to care of filtering and timestamping the pictures.
