They are good at figuring out what one might need for radios - sounds like they speak using radio-frequency. I wonder what else they can figure out! I was hoping to see the options, but it sounds like we need to know what we want before we ask for things instead of seeing what there is to work with. They would want us to replace anything we use - by amount, not necessarily by equivalent quality.
