[CQ-Contest] SO2R with modern computers

[Yo3ctk]

Hi all,

We at YR7M would like to try our hand at SO2R. We already have a moderately competitive M/S setup, essentially equipped with monobanders and CAT radios, along with ICE band filters, band decoders and Six Pack antenna switching system. We're using WL software. I was looking at the DX Doubler for completing the automation of the station. However, it seems that a parallel port is essential for this device, and our computers are all laptops, with only USB ports.

Is there a modern alternative to the DX Doubler (or similar boxes) that are only using USB ports? Thanks for any hint.
