I checked out the Olympus WS100 recorder with a SRF-T615 and E100, and am not totally satisfied with the results.
It seemed a normal listening volume overloaded the recorder a bit.
While recording R. Rebelde 1180 I noticed the recorder emitted noise near that frequency. It wasn't noted on the other frequencies I recorded (530, 670, 710 and 890 kHz). Some of the noise was eliminated by increasing the distance between the receiver and recorder but it was still evident at 1.2 meters (4 feet).
