Q: What makes FM the ideal bandwidth for broadcasting?

A: There is only one answer to this question.  FM band transmission is clearer so it cuts down on static, pops, and crackles. That means that you get to hear the broadcast that you are tuned in to without all of the background noise and distractions.  

Q: How do I find a good channel?

A: Unless you live in a very remote part of the continental US, you will want to conduct a personal frequency search. Using a quality digitally tuned FM receiver, start listening at the top of the FM band (107.9 MHz). You want to slowly tune down the band searching for empty or very weak channels between two strong stations.

Q: Are some channels better than others?

A: Yes. While you can use any clear channel, interference caused by full power licensed broadcasters may affect your reception of the Landmark Pro Series resulting in subtle audio distortion or faint tones. These are especially noticeable at low volumes on some channels. During speech or quiet passages you might hear a faint tone or low volume musical passages that have a fuzzy quality or the background noise may be varying with the modulation of another FM broadcast station. In every case, the best cure is to find another channel than the one you are on.

Q: Where should I set up my Landmark ALD Transmitter?

A: Your antenna can be anywhere within up to 200 feet of the receivers you want to reach.   In general for best coverage, the antenna should be at the center of the coverage area,
as high above as is reasonably possible.

Q: Can I use more than one Landmark Pro Series in the same area?

A: Yes, the advanced design of the Landmark Pro Series allows multiple transmitters to operate . We suggest using channel that not adjacent. Even if you are using several   individual units, there is no significant interference between
the Landmark Pro Series or with other 72- 76 mhz users.

Q: How can I adjust the volume that the transmitter outputs?

A: There is a pair of volume controls for adjusting the modulation (transmitter volume). For most channel settings and audio sources, the 12 o'clock or 50% setting is the right place to start. While your transmitter performs well on all channels, each unit is factory adjusted for peak modulation quality.

Q: Where can I find information about FCC regulations?

A: In order to gain more information about FCC regulations you can visit the FCC at www.fcc.gov. At this site you can find information about rules, regulations, and the latest news related to the FCC.

Here are the most important ones you need to know.

- NEVER use a fake call sign. If you broadcast content with voice announcing , you can say things like "this is Palm Estates broadcasting"; but must never say "this is WABC-FM". Using a false call sign is a serious Federal offense.

- If notified formally or informally that your transmissions are causing interference, you must cease operation on that channel and find another. Failure to do so can result in equipment confiscation or fines levied by the FCC.

-You may not use any other device to increase the power of the FM-350. Any means that increases the power of the transmitter will bring it under the licensed jurisdiction of the FCC. It is YOUR responsibility to obey the law.

Q: What are the advantages and disadvantages of using Stereo as opposed to Mono?

A: It's all about range and sound quality. Stereo provides the best listening experience. Mono operation gives the best range. If you need the maximum range, and the signal is noisy or shows fading or interference, mono will generally add 30% to the useable distance over which you can hear the broadcast signal clearly. In addition, for spoken word only Mono is often a better choice.

Q: I want a cost effective replacement to the high cost proprietary receivers offered by our competitiors?

RadioOrpheus has everything they don't want you to have. A low cost, high quality receiver that will pick up ANY FM listening assistance (ALD) broadcast no matter what frequency they use. Every channel setting used by our competitors can be traced to an actual FM frequency. This chart explains the frequency breakdown used by our competitors for listening assistance broadcasts.
