SLOW-SCAN TELEVISION (SSTV) WITH VC-H1

Slow-scan Television (SSTV) is a popular application for transmitting still images over the air from one station to another. The VC-H1 is an optional portable unit which includes all requirements for SSTV; a slow-scan converter, a CCD camera, and a LCD monitor. You can transmit or receive full-color images just by connecting the VC-H1 to this transceiver. For further information on the VC-H1, see the instruction manual for the VC-H1.

From this transceiver you can enter and superimpose a message, an RSV report, and a call sign onto an image on the VC-H1 monitor. You can also select colors for those information.

Note: Use an optional PG-4V cable to connect the VC-H1 to this transceiver. For this cable, contact your authorized KENWOOD dealer. The cable that comes with the VC-H1 allows only image transfer from/ to other stations.
