*** YMMV depending on equipment. I found I had to push the record level
to distortion to obtain adequate audio level on my recordings on AM. My
FM tuner provides two different output impedances and levels. I had to
step down the impedance to run stereo cans at adequate level, but the
match to the PC sound card was fine since the tuner output impedances
are in the same range which I step up to from the HQ-150.
