Auburn Road Frequency Control
The NH Flying Tiger's Frequency Control Board is located at the center of our pit area. The key which opens the gate will also unlock the frequency control board. The first person to arrive
is responsible for unlocking and opening the frequency control board. The last person to leave is responsible to ensure that the frequency board is closed and secured with the lock. Note that there are
two sliding metal bars inside at the bottom which will hold the two doors open. Rotate them as you slide these bars out to hold the door open, and then
retract them to allow the doors to be closed.
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 your transmitter or transmitter module 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 must be used for all radios including 72 MHz aircraft frequencies, 2.4 GHz (Spread Spectrum or DSS systems), as well as the 50 MHz Amateur Radio Frequencies ( Ham frequencies require that you have a valid amateur radio license).
You must also use this system for 27 MHz and 49 MHz frequencies as well, most of which are for use and coordination with small, lightweight (park flyer) type of aircraft (be aware that surface models such as 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 and therefore is "Not recommended for use".
If the frequency control board is ever removed for service, each person flying at this site 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 2.4 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 turning on your transmitter or flying. An example of a Frequency Control Pin is shown.
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.
