Hi Stefan

My fault on the frequency, I must pay more attention, you are generating 
with SpecLab and you did say
> The QRG is centered at 8969.98000 Hz. The DFCW shift is 3 mHz.

To be pedantic that is DFCW with a shift of +1.5mHz and -1.5mHz and CF 
of 8969.98000.:-) :-)

However I had lost frequency lock on 424uHz anyway.
When ever I look at your second Grabber it is dead, like NOW, so I 
didn't look to compare, and I was in the garden planting out so as to 
catch this lovely Bank Holiday rain.:-)
