I just moved to Chicago and have found that there are no longer any

.1, .3, .5, or .7).

Having lived in Chicago, may I suggest you pick out a frequency and see
which one works best while producing a stronger signal that what is
received on the frequencies you have available. Unless your FM receiver is
subject to overload, the FM modulator should produce enough of a signal for
you to produce a big enough dB difference that the modulator signal
captures the FM receiver.


One other approach if your lease is retro enough to have a tape player is to
find one of the formerly common adapters with a plug and plug that into the
XM receiver. Most XM receivers I've seen have audio available through a
common 1/8 inch stereo jack, meaning that any matching audio technique will
work. You also may have jacks on the radio in the car which would allow a
straight audio connection.
