Dex,
fine - looking forward to try again, I reckon we'll
need about 3 dB more. Unfortunately my antenna still won't be fully
extended for a couple of days due to wind condx.
EDDS = enhanced deep deep search? It might be more
efficient to try the 4 hour mode then ;-)
There's still a very slight frequency
instability on the RX side: I'm tracking DCF77 to eliminate the FiFi-SDR's LO
drift, but currently have no means to simultaneously correct for samplerate
deviations. But I think the residual drift (about 1 mHz) is too
small to affect opds-16 or -64 sensitivity in any way.
Best 73,
Markus (DF6NM)

My frequency is GPS locked so it should have been
exactly on 74.323. I will run again tonight on 74.3229 if you are
available for another try. I just changed the frequency and will
let it run during the day for you to try an EDDS test
:)
