The signal is much too strong to be a good test, you should
still decode quite easily at DF6NM if you drop to 5W.
I got the system noise down to 1.5nV/m per root Hz which is
far lower than it needs to be I think. I'm a bit worried about
tuning drift with the junk box parts. Front-end filter Q is
high and as tuning drifts with temperature change it will throw
the phase calibration out. When a distant carrier shows a
phase change during the night, I won't know if it's real or
just the front-end cooling down.

Not ready yet. Lots of work still to do.
Today I built the antenna and I already have cable run out to
the rx site. This week I'll put it all together but I don't
expect it to work straight away. There will be oscillations,
overload, intermod, interference - all the usual problems, and
I'll probably have to make up some new software to get a clean
PPS timing measurement when the LF is mixed in with it.
