Hi Jeff,
Congrats on the purchase of your 7200. It’s an awesome rig and the built in interface works great so don’t worry! Have you received yours yet?
I was basically swapping to the Signalink out of pure laziness. When swapping from SSB phone over to JT 65, the 7200 requires a few extra menu button presses when switching modes than what is required by the Signalink. I also like the physical knobs for TX and RX on the Signalink, though all of those levels can be manipulated with the sliders in the WSJT-X program.
What modes are you planning on using on the 7200? I’ve had the IC-718, the IC-7000, and now the IC-7200 and I have to say the 7200 is the perfect ratio of simplicity vs features for the way I use it.
