The graph is now calibrated and reads actual input power into the 75 ohm terminated input of the HP SLM. I finally figured out how to use the 100 db dynamic range of this instrument. The output tracks perfectly with Spectrum Lab. The antenna is a 3.3 meter square loop with no amplification. The plot is uploaded every 5 minuets to: http://www.w4dex.com/75khz/hbg.jpg The daily plot will be stored in the 75 khz directory at: http://www.w4dex.com/75khz/ If there is blank data for a period it will probably be due to shutting down during thunderstorms. I would like to run on this signal through the winter solstice. Then I could change to whatever signal is deemed to be useful. Comments and or suggestions will be appreciated. My thanks to Wolf for Spectrum Lab and his assistance. Dexter, W4DEX www.w4dex.com
