Regarding Observation 3070365 …
Hello,
When listening to this observation 3070365, I can hear ‘CAMSAT BJ1SE’ between 04:30 and 04:42,
which seems good, but nothing is decoded in the ‘Data’ tab.
Also there is a strong QRM/QRN as background, is that a local noise or does it comes from the air ?
Can anyone please advise ?
Thanks and regards, 73’s Benoit ON3ZZT
The CW decoder is not as good as your ears, and requires a pretty high SNR to get good results.
The noise you are seeing is most likely local. More likely since your station is named ‘indoor’. Lots of seemingly innocuous devices produce large amounts of noise on the 2m and 70cm bands.
You might want to try turning off devices around your receive system and see if the noise drops away. It’s probably easier to do this while accessing your SDR via SoapySDRRemote (see here: https://wiki.satnogs.org/Omnidirectional_Station_How_To#Setting_the_gain ) rather than scheduling observations.
Thanks Mark !
I understand that, with all the noise, the automatic CW decoder doesn’t perform well 
Yes the antenna is indoor in the attic, but with the outside antenna, I’ve got same problem.
I’ll try to remove noisy devices and follow the gain procedure again.
