B-Street Frequency Control

The NH Flying Tiger's Frequency Control Board is located at the center of our pit area under the shelter.

The only allowed method of reserving your frequency for flying is to cover the channel you are using with your valid AMA card or a duplicate of it. If a transmitter is not in the impound, then the channel number of that transmitter must be reserved by placing your current AMA card over the appropriate channel. This also allows us to be sure that you have valid AMA insurance coverage.

This frequency control system allows for using all 72 MHz aircraft frequencies, as well as the 50 MHz Amateur ( Ham ) frequencies if you have a valid amateur radio license. Our frequency control board allows four pilots to use 2.4 GHz systems. 27 MHz and 49 MHz locations are for use and coordination with small, lightweight (park flyer) type of aircraft (be aware that surface models (cars and other childrens toys) may also use these channels, so you must use extreme caution when flying using 27 MHz or 49 MHz at our flying site.). Please note that the use of the older 53 MHz frequencies is not safe at this (or any other New England) flying site and is noted as "Not recommended for use".

During the winter months we often take down the Frequency Control Board and install a Frequency Control Stand near the Pilot Stations. When the field is in this 'winter mode' each member is responsible for creating and using a Frequency Control Pin which is usually made from a 3 inch by 3 inch card which has your channel number (or 2. GHz as appropriate) displayed in large, easy to see numbers. You should also place your name on the card for easy identification. A clip or clothes pin on the rear of the card will allow you to fasten your Frequency Control Pin to the Frequency Stand along with your current AMA card to secure your frequency before flying. An example of a Frequency Control Pin is shown. If our normal transmitter impound area is not in place, it is up to the members present to agree upon and use a designated transmitter impound area.

Here is a graph of Aircraft channels used by NH Flying Tiger's members. Note that some members may have synthesized transmitters and these may operate on any channel. This data is only as valid as the information provided by the club members.

Please note that the use of RC channel 20 in our area may be affected by TV channel 4. Although the NH Flying Tigers are not aware of any issues with the use of RC channel 20 (or RC channel 21) for the use with aircraft at our Londonderry flying site, you should still be aware of the potential for interference. Many New England RC clubs to the south of us do not allow the use of RC channel 20 at their flying site due to the possibility of interference from TV Channel 4.

This is a graph of Amateur Radio channels used by NH Flying Tiger's members. This data is only as valid as the information provided by the club members. Note that you must show a valid Amateur Radio license to use these frequencies at our flying field. Also be aware that surface models (cars and other childrens toys) may also use these channels as well as local and distant Amateur radio operators for communications so the channels 00 through 09 should not be considered 100% secure for use with flying aircraft. Use with extreme caution!

The older 53 MHz frequencies should not be used in the New England area due to the many active Amateur radio repeaters which are active in the region and can generate considerable interference to flying aircraft.

This is a graph of Land channels used by NH Flying Tiger's members. This data is only as valid as the information provided by the club members. Please note that these channels may not be use for any type of aircraft at our flying field!

This is a graph of 27 MHz and 49 MHz channels used by NH Flying Tiger's members. This data is only as valid as the information provided by the club members. Please note that these channels are only recommended for use on with light, small type of aircraft (such as park flyers) which fly at very close range at our flying field.
