Abstract

Moon-reflected signals were received on 150.6 mc and 413.25 mc on 36 days during the quarter. Data have not been analyzed for correlations with magnetic and solar activity which occurred during the times of observation. A phase-lock receiver, designed to stay tuned to the incoming moon-reflected signals at 150.6 mc, is working well. Small errors in antenna position, both at the transmitter and at the receiver, lead to errors in Faraday rotation angle at 413.25 cm, which can cause erroneous resolution of the n X 180 degree ambiguity. When observations are made for one or two hour periods these errors tend to cancel. A thesis for the M.S. degree, by Capt. J. L. Geisinger, dealing with the design of circularly polarized antennas for 150 mc, is appended. (Author)
