You don't have to apologize! That's exactly the right attitude!

Did the overload damage your system or ruin your calibration? Maybe there’s no way to prevent it if the ionosphere is being blasted. ?

These overload conditions occur in most ADCs when the magnitude exceeds 0 dBm. Usually, it's not even individual narrowband signals that trigger this, but rather the sum of several high-field signals when there's a lot of power across the entire spectrum, as was the case during the contest. The ADC could certainly be damaged at some point, but I hope the hardware contains mitigating measures.

Tyson,

that really looks great!

It appears that there is a file size limit at 2 GB. Jim describes one way to automatically record data here ("Run Timed Observation" from the "File" menue):

/g/radio-jove/message/7640

?

Another way is "File/Run From Schedule File". You'll find the description of the .skd file in RSS' Help file.

Do you have a photo of your new location/antenna?

Hi all,

Jack Ganssle and I were able to setup a dual dipole kit about an hour northeast from the Mills Cross Array historical site, far enough from Washington, D.C. and Baltimore for reduced interference. ?

Attached is a shot of a recent observation.? Any feedback would be greatly appreciated.

We ran into a file size limit in Radio Sky Spectrograph with an initial dataset.? The file was 2GB total.

What is the file size limit and is there a way to automate stop/start for file creation in RSS?

Thanks so much!

The ionosphere didn't really get going in the morning after a first prominent teepee arc around 06:25 UTC. In the evening, the airglow was just as quickly gone long before the sun had set.
