If their ID is WMRQ-HD2, then why can I receive them on 97.1 on a regular FM receiver?
This station broadcasts on two different frequencies:
- They broadcast on a HD signal on 104.1MHz, for which the call letters are WMRQ-FM. You do indeed need a HD Radio to receive this signal.
- They broadcast on an FM translator on 97.1MHz, for which the call letters are W246CC. This is an analog station which can be received on a regular analog radio.
What is the difference (if any) between 100 watt Bomba97.1 & an LPFM like WZBG/Litchfield?
- As MarcB says, WZBG is not a LPFM. And as he says, WACC-LP 107.7 Enfield
is a good example of a LPFM.
From a technical standpoint there is little difference between W246CC and a LPFM. They do hold different types of license.
- The maximum power permissible for a translator is 250 watts, if no interference is caused to other stations. The antenna height of a translator is essentially unlimited, again as long as no interference is caused to other stations. Translators can be licensed at lower powers if higher power would cause interference.
- The maximum power permissible for a LPFM is 100 watts. A LPFM will not be licensed if it cannot use 100 watts without causing interference. The maximum antenna height is 30 meters -- higher antennas are permitted but power must be reduced to compensate.
- Translators must relay some other station -- they cannot originate programming themselves. In La Bomba's case, they're relaying the WMRQ-FM HD2 digital signal.
- LPFMs may originate programming.
