I was lucky to find a QS1R multi-band SDR on eBay. They work out of the box across 7 bands simultaneously with CW Skimmer Server. Unfortunately the QS1R was discontinued a long time ago and there doesn’t seem to be an easy to setup equivalent.
My setup is:
Windows 10 Pro 64 bit, on an old Dell Optiplex ex office PC (i7, 16GB RAM, 128GB SSD). The requirements for Skimmer are not such a powerful PC, but they are cheap on the refurbished market.
QS1R fed from a home made PA0RDT active antenna in the far corner of the garden (details on my web site). My DC feed interface for the active antenna drops the DC when I transmit on HF.
I combine my local Skimmer spots with the DX cluster using Wintelnetx (free utility), which allows me to set the local log program to receive both, or just mine, via a button in Wintelnetx... no change needed to the logging program cluster settings to switch.
I sometimes upload Skimmer spots to the RBN via the Reverse Beacon Aggregator utility program, obviously set to work directly with Skimmer Server... not the combined output of Wintelnetx.
The above works very reliably, the only difficulty is obtaining a suitable RX.
