Markus, group,

Thank-you for the insipiring anecdotes and signal reports.
I am sad to report that my dad  G3LMD/ VO1FB became a silent key
yeserday morning.

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:

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.

Hi Joe,

the carrier on your frequency is nicely visible night and day. 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.

Hi Markus, Stefan EbNauters,

Thanks for the reports and autodetectors.  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.
