Paired it with my IC-7610 and WOW!!!

Bob, KW4CQ just posted this review of the RSPduo over on eHam reviews

I recently added the RSPduo and SDRuno to my arsenal of DX chasing tools and I'm so glad I did. The spectrum analyzer and waterfall display aided me in no small way in finding an opening in the recebt KH1/KH7Z DXpedition pileup on 40m cw. I paired the RSPduo with my Icom IC-7610 sharing a common antenna using the Icom's RX/IN and RX/OUT ports. I used a Mini Circuits ZSC-2-2+ Power Splitter to make the connection between the Icom and the antenna. For added front end RF protection to the front end of the RSPduo I placed an Array Solutions RF Limiter/Arrestor, Model AS-RXFEP in line with the Icom RX/OUT and the RSPduo antenna input. Full tech specs on these relatively low cost devices are available on the manufacturer's web sites. My display is a 27" Samsung monitor, which gives me a fantastic view of SDRuno's controls, frequency spectrum bandspread, and waterfall. A pair of Bose sound powered PC connected speakers produces some awesome listening pleasure on SSB signals from the RSPduo. I can conveniently operate transmitting on the IC-7610 while listening and spectrum monitoring on the RSPduo, or on the 7610 alone.
Try it you'll like it.

Bob,

Very cool. My RSPduo just showed up, and it seems to be a pretty impressive receiver. I also just received my splitter from Mini Circuits.

My question is.. is the Array Solutions limiter really necessary or does the 7610 provide enough isolation on the RX IN/OUT loop to protect the RSPduo?

Thanks & 73 de KM8V
