Hello Markus,
There seems to be a problem with the time in spectrum lab. The time in
the text box is correct, however the time in the X axis is correct
when I start spectrum lab, but seems to be going faster over time. The
solution is to restart spectrum lab before I go to bed every night, to
ensure that the offset is minimum, however I forgot to do that
yesterday. Does anyone have any suggestions how to fix this?
I have been monitoring the DCF39 signal (peak_a in a 20 Hz window
centered around DCF39) and noise_n for the past few months. This has
worked well with my little ISDR-136 receiver in the past but I have
had some difficulty to get it going with the tentec RX331. No doubt,
it will be probably a setting somewhere in spectrum lab, but haven't
had a chance to troubleshoot this so far. Hopefully it will happen
this weekend.
73, Dimitris VK1SV
