I wouldn't swear to it being a tone sharp (or 1.6 semitones) but it was definitely VERY high, and consistent. The program was actually two hours (or 1'54" as it turned out). The station must be automated in the evening, hence the station break at precisely 9:59. The station is WXXI-FM in Rochester NY.

Ah-With Heart and Voice. Such a nice program. Give them a break.
