The audio on 97.9 is awful and they don't ID this translator at the top of the hour.
From reading those here who know more about translators, I see that they can ID code or do an originating station ID just every few hours.
Here are the actual rules:
47 CFR § 74.1283 - Station identification.
§ 74.1283
Station identification.
(a) The call sign of an FM broadcast translator
station will consist of the initial letter K or W followed by the channel number assigned to the translator and two letters. The use of the initial letter will generally conform to the pattern used in the broadcast service. The two letter combinations following the channel number will be assigned in order and requests for the assignment of particular combinations of letters will not be considered.
(b) The call sign of an FM booster
station or
LPFM booster will consist of the call sign of the
primary station followed by the letters “FM” or “LP” and the number of the booster
station being authorized, e.g., WFCCFM–1 or WFCCLP–1.
(c) A translator
station authorized under this subpart shall be identified by one of the following methods.
(1) By arranging for the
primary station whose
station is being
rebroadcast to identify the translator
station by call sign and location. Three such identifications shall be made during each day: once between 7 a.m. and 9 a.m., once between 12:55 p.m. and 1:05 p.m. and once between 4 p.m. and 6 p.m.
Stations which do not begin their broadcast before 9 a.m. shall make their first identification at the beginning of their broadcast days. The licensee of an
FM translator whose
station identification is made by the
primary station must arrange for the
primary station licensee to keep in its file, and to make available to FCC personnel, the translator's call letters and location, giving the name, address and telephone number of the licensee or his service representative to be contacted in the event of malfunction of the translator. It shall be the responsibility of the translator licensee to furnish current information to the
primary station licensee for this purpose.
(2) By transmitting the call sign in International Morse Code at least once each hour. Transmitters of FM broadcast translator
stations of more than 1 watt transmitter output power must be equipped with an automatic keying device that will transmit the call sign at least once each hour, unless there is in effect a firm agreement with the translator's
primary station as provided in
§ 74.1283(c)(1) of this section. Transmission of the call sign can be accomplished by:
(i) Frequency shifting key; the carrier shift shall not be less than 5 kHz nor greater than 25 kHz.
(ii) Amplitude modulation of the FM carrier of at least 30 percent modulation. The audio frequency tone use shall not be within 200 hertz of the Emergency Broadcast System Attention signal alerting frequencies.
