Digisonde operation at Maynard, Massachusetts
Abstract
Routine maintenance and calibration of the Digisonde system in Maynard, Massachusetts was performed during the period from 1 October 1973 to 30 June 1974. Power line fluctuations caused a series of shutdowns of the old C-4 transmitter used as power amplifier. Reliability of the system improved after installation of a modified Granger amplifier. The station presently uses the Granger intermediate amplifier feeding 500 W peak power (10 W average) to the transmitting rhombic antenna.
