Hello W5JA, and welcome to the community!
We are in the process (it happened this morning) of transitioning the previous ShakeNet portal as explained in this topic: ShakeNet Web Portal Transition
Thus, the main hub for displaying data from all Shakes has become DataView and, in the case of replicating the ShakeNet display, its MultiStream feature. While it may not be exactly the same, it offers similar channel display capabilities, along with enhanced features such as filtering live incoming traces and a double waveform/spectrogram live display for each channel.
I’ll add a link for readers who may not know how to reach it: https://dataview.raspberryshake.org/
Again, welcome to our Shake family! I hope you’ll enjoy your new instrument!
