This week the EbNaut autodecoders at DL0AO and DF6NM have been refurbished, producing more compact output with one line for each successful decode. My current script and required utilities are here: http://df6nm.bplaced.net/VLF/fec_tests/ebnaut_autodecode_scripts.zip Our autodecoders are currently observing 137477 Hz. Until yesterday, VO1NA has been making strong and consistent decodes every night. Today I'm doing a few of low-power daytime tests on his QRG, with the LEA-6T barefoot to the antenna.

When the signal is strong, some symmetrical sidebands become visible, are you still modulating with 7 char EbNaut messages every other half hour? I've placed my current autodecoder scripts here but note that this setup is driven by opds and sort of specific to my LF grabber. For Linux, you may want to start from the scripts which Domenico has recently posted.

The TX carrier is on continuously at 50 watts with the excitation XOR phase inverted by Paul's Ebkey.c on a raspi3. There have been some daytime decodes recently. Is the autodetect easy to set up? If not perhaps I'd best review the advice from you and Stefan again. 73 Joe |
