Important Notice: In Canada it's illegal to operate aircraft models on the
frequencies 72.080, 72.160, 72.320, 72.400,
and 72.960 (in RED). Their use
is no longer allowed due to the close proximity to the other channels and the
fact
that equipment using these frequencies would be wide band and technically
out-of-date. Pilots disobeying this ruling
risk hefty fines and confiscation of
their radio control gear.
* 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While the warning was originally for PCM sets, and a bit outdated now, there is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 causes 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.
