Abstract :
A telemetry system used to remotely record a primate´s body temperature is presented. A transmitter implanted in the retroperitoneal space of each monkey transmits a pulse at a frequency that is linearly proportional to the body temperature of the monkey. This signal is transmitted on a carrier frequency in the AM band of 27 MHz. The signal is demodulated using a Sony ICF-2020 receiver. Once it is filtered, the signal is sent to a Digital PDP11 data collection system. A solution to the problem of antenna placement is described. Results show an immense improvement in the signal strength and reduction of noise
