Hello Hobby Squawk forum,
While some years with DC electronics have been acquired, an excursion into radio frequency world is fairly recent.
l
A device that drops a payload from a single line kite has been developed. The device,
called the KiteMessenger
uses a sail to ascend the kite line and a 433 mhz transceiver to drop a parachute
load and allow the KiteMessenger to descend back down the line so the operation
can be repeated.
Several transceivers have been employed in an effort to increase the range of the transceiver.
The latest transceiver
Wireless Relay 12V Long Range Remote Control Switch, Universal 433Mhz RF Transmitter Receiver Mini Remote Relay in Latched Module for Home Use and More DC 3.7V 4.5V 5V 6V 7.4V 9V 12V - - Amazon.com
will send the signal out a 1000 meters on the ground but up in the air, for some reason unknown,
the maximum range is about 90 to 120 meters depending on atmospheric conditions.
A parachute drop of about 150 to 200 meters is sought.
Research on single channel remote control transceivers that can send a signal to
a microcontroller
indicates that besides the transceivers found on Amazon
like the '433 mhz Wireless Relay 12V Long Range Remote Control Switch' referenced above
there are also transceivers in the 915 mhz range.
The question is:|
Will using a 915 mhz transciever increase the range as compared to a 433 mhz receiver?
That is, there a relationship between frequency and transmission range?
Thanks.
