I'm currently trying to build a desktop Datatrak LF signal simulator, and reverse-engineer the receiver to the point where they could be used to receive signals in the 136kHz (2200 metre) UK LF amateur radio band. | I'm currently trying to build a desktop Datatrak LF signal simulator, and reverse-engineer the receiver to the point where they could be used to receive signals in the 136kHz (2200 metre) UK LF amateur radio band. |

You may also find my presentation at CampGND interesting: [[https://panels.sneptech.io/campGNDd_RadioLocation_Datatrak.pdf|(slides)]] | You may also find my presentation at CampGND interesting: [[https://panels.sneptech.io/campGNDd_RadioLocation_Datatrak.pdf|(slides)]] [[https://www.youtube.com/watch?v=nB_3iod6LR8|(recording)]]. It was difficult to cram so much into 30 minutes and is quite fast paced. Hopefully I'll be able to give a more detailed talk at a later time! |
