These Sirius radios sure do have strong FM TX's!
I bought a Sanyo CRSR-10, and was surprised to see how much stronger its FM signal was than my XM MyFi. The MyFi must be within a few feet of even the most sensitive radios I have, for the FM signal to be heard.
The CRSR-10, OTOH, can be heard at the other end of my home with a nice signal, on a good radio. I wish the MyFi had such a strong signal. As it is, to listen to XM in other rooms, I must either take the MyFi with me, or plug it into my Part 15 AM TX.
Getting to your question - on the right side of the CRSR-10, there is a jack labeled "FM OUT". According to the manual, this is intended to be connected to a signal injector, as one would use in a vehicle installation to connect in between the existing antenna and FM radio. It would probably be an interesting experiment to connect a pair of "rabbit ears" to this jack and see the results. However, the "FM OUT" is a little headphone-sized jack, and I have lost track of the adaptor I'd need to get to the 300 ohm "flat cable" that my rabbit ears offer.
