* HAM Radio Operators are alowed to operate equipment on the 50 & 53 Mhz frequencies. The 72Mhz band, channel 11 - 60, is exclusively for use with all model aircraft. The 75Mhz band, channel 61 - 90, is exclusively for use with all model cars and boats. The old 27Mhz band, channel 1-10, is still allowed but no longer used since its range is wide-band and most likely will conflict with other equipment on these freq's.

A warning was received from MAAC concerning the Futaba 8UAF/P and the Digital Computer Radios.

Warning 1: The Futaba 8UAF/P series radio should be checked for a loose connection between the transmitter's frequency module and the radio itself. Apparently, the little 5-pin connector that is soldered into the radios' circuit board cracked (cold solder joints?) and the radio ceased to function. Please inspect your radio before it is too-late!

Warning 2: (Updated March 12, 2000) Several clubs and associations have put out a warning about using cell phones near computer radios. It appears to be cellphones of inferior designs, most of them coming from Asia and mainly China.
There have been a number of occasions where these radios have either lost their settings or had them scrambled. There was one case where a large model had its throttle failsafe reversed so that it went full throttle on failsafe. There had been testing which confirms that using a cell phone close to a computer radio can cause a loss of memory settings. The recommendation is that cell phones should not be used within a 10 feet (3 meter) radius of any type of computer radio OR receiver. While the warning was originally for PCM sets, there is evidence that PPM (or FM) is also affected. I personally would recommend to keep cellphones out of the pit area all together. After doing some more checking I came to the conclusion that it concerns not all cellphones but only some models. The owner of Flight-Craft Hobby Shop (Steve Gray) in Kitchener mentioned that he uses his cellphone all the time in the vicinity of his radio and has no problems whatsoever.
This proves my point that not all cellphones cause this type of interference. The problems they encounter in the UK and other parts of Europe may very well be related to the different frequencies they are using for both cellphones (freq. unknown) and radios (35Mhz). I like to say 'use good judgement and don't take any risks' especially with helicopters.
