On the latest count, there are six Perseus SDRs, one NetSDR, one Winradio G31DDC and two Winradio G33DDCs. There are around 20 hard drives (mostly Seagate and Western Digital) from 2 to 4 TB each.
The boxes on top of the Perseus in the picture are preamps. The boxes below are antenna switches.
We also have three Telenor 3G internet modems with typically 17 MBPS down and 3 MBPS up for remote operation. 3G is a vast improvement over the previous 450 MHz ICE internet connection. All internal network connections are cabled, no wifi.
The PCs are everything from large desktop to small desktop to micro desktop (Intel NUC) and laptops. They range from very new processors to at least two years old. OS is mostly W7-64 but also W8.1-64. Mostly the hard drives are connected through USB 3 ports.
We want to avoid cheap, noisy, switching PSUs, so all the hard drives are powered by amateur-grade linear PSUs (mostly Diamond). Everything save the PCs are using 12VDC. The Perseus and NetSDR are powered by USB 3 from a PC or (mostly) separate linear 5V supplies. The original PSUs are not used.
