WTAN - Legal ID Not Legal?
- Thread starter wlsl
- Start date
I believe that it's perfectly legal. FM106 is a WTAN translator ... it is not a radio station.
You are correct b-turner.

Translators must be identified three times daily during their hours of operation. The three times daily it must be identified are: (1) between 7 a.m. and 9 a.m., again between 12:55 p.m. and 1:05 p.m., and finally between 4 p.m. and 6 p.m.

Especially this one, since CW is the abreviation for Morse code.
I'd think that a Morse code ID on an FM transmitter would be an audio tone, not CW.
It's code, not CW. "CW" is "continuous wave" where code is transmitted by alternating the carrier on and off with tone modulation. AM stations do not cut carrier between dits and dots.
Translators can use Frequency Shift Keying (FSK) to identify the station in Morse Code. You would not hear this id on the air.
74.1283(c)(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.
Either (i) or (ii) is legal. Most stations use FSK which shifts the frequency of the station to identify in Morse Code. This is inaudible on air, but can be detected by the FCC.

What does one call an A2 emission;
AM tone modulated code?
It has always been used to ID beacons.
Yes, but that's not CW, which is on/off keying of a carrier (or an audio tone modulating an SSB transmitter).

That's why you need a receiver with a BFO (beat frequency oscillator) to receive CW clearly. Without the addition of a carrier, the dits and dashes sound like buzzing/humming.
But that's not what we're talking about here. An FM translator will not be ID'ing this way. But if it's using FSK, I would think that the minimum 5 kHz shift would be preferable, to minimize disruption of the FM sound.

What was heard was NOT one of their thrice-daily legal ID's; it was a promo.
WTSP id
Its not. It should be "WTSP St. Petersburg, Tampa" because the City of License is St. Petersburg. I'm told the News Director insists Tampa come first. WTSP has been violating the law for years.

KPNX Phoenix (COL Mesa) AZ IDed as Phoenix/Mesa for 50 years, not fixing it until the analog was shut off in 2009. Now it IDs correctly as Mesa/Phoenix.

Correct, for full power stations.
WKIS barely places 70dbu across the farthest edge of their COL,
and only when considering ground anomalies; they miss the northeastern corner on normal maps.
LPFM's do not even have to do that.
WLJM-LP's 60 dbu does not quite touch their COL and WJEW-LP's comes nowhere near theirs.
