DTMF-8

DTMF-8 is an inexpensive, self contained, DTMF (dual tone multiple frequency) decoder board which permits users to control remotely, via radio or other audio producing source, the on or off state of eight devices. For larger applications several DTMF-8 boards can be attached to the same control audio source to control dozens of devices. DTMF-8 supports four modes of operation.

OSD-GPS (ID): On-screen display GPS board with ID

$119.00

Description:

OSD-GPS (ID) is an on-screen display board that overlays NMEA 0183 GPS latitude, longitude, heading, speed, time, and optional altitude onto an incoming NTSC or optional PAL video source. In addition, a user defined message like an amateur radio callsign can be overlaid on-screen to meet FCC id requirements. The on-board button keypad allows users to program their callsign which is stored in a non-volatile eeprom so even with loss of power the callsign is retained.
