FT8 Transmission using Matlab script, HackRF One

transmitting FT8with my HackRF One using a 2W rf amplifier connected to 10m length of coax using one conductor as the antenna. This was connected to the hackRF. Five pieces of software used. For the FT8 audio signal a MATLAB script using precomputed FT8 channel symbols sent from PC speaker headphone output to line in on my laptop. Used SDRangel to USB modulate a carrier and send this to the hackrf. To monitor my transmissions, used an rtl-sdr dongle set up in SDR# and fed the received audio to WSJT-X 2.0.1 using VB Audio cable all running on Windows 7. So far successful Tx over short distances only..
