Long Wave Radio Receiving Measurements at the Bureau of Standards in 1929

This paper gives monthly averages of daylight signal intensity at Washington for 1929, as received from a number of European and American low-frequency stations. Several of the stations formerly measured have ceased to transmit regularly at hours sutitable for all-daylight transmission paths and their measurement has therefore been discontinued. The annual average field intensities of the European stations have not shown much change since last year, but the atmospheric disturbances have increased.
