Thank you Marco, the last maintenance on my grabber-PC was obviously too late in the night.
Without your reference, I might have let it run until Monday :)

me too although I regret I have no longer a cat :-(

I had to take a picture after I was successful repairing my LF/MF
exciter... damnd Si570 aaaargh I really wish to see in the eye balls
who projected such IC chip container..
Anyway I'm finally active on MF wspr but probably need to add a
variometer also for MF nevertheless the relative high SWR the antenna
is performing quite well. Yesterday and last night missing the standard
generator of the LF/MF exciter I was on the air running the venerable
Singer CSM-1 as generator getting plenty os spots.
Thanks everybody for listening and uploading spots.
Just a quick note for Vinny.. give a look on the setting of wspr:
yesterday and today I'm on MF only ;-)

Could be.   No such problems here due to using LP smoothed
pulse for centroid measurement.

Needs about 15.9 Gbyte RAM when using the optimum list
length of 62k.   Would be a silly amount of memory except
that it works.


I feel better knowing that your workbench constructions look a lot
like mine!    One stray cat and the whole thing comes to pieces.
