THE STEALTH
The Confidential Catch
The
KN2C DF2020T
is an economical but very sophisticated Doppler DF "kit" with a GPS
input, and RS232 output to provide the ability to indicate its location and draw bearing
automatically or manually on Google Earth map to find the RF transmitter more conveniently.
KN2C-2020T
kit Includes eight assembled / tested PC boards: MAIN board and 2 Sub boards
in the main unit, and five antenna boards in the antenna modules (one for each of four antennas
and one for auxiliary antenna). Completion work is required by the user to finish the DF main
unit. Guidelines for the completion work are provided.
The user must provide a NB FM receiver, antennas and a PC for DF bearing (Windows OS).
DF2020 display program further requires a GPS receiver with NMEA 4800 baud output.
