Preparations to begin meeting an order of components used in unmanned aerial vehicles contributed to AML Communications Inc. posting lower revenue for the second quarter when compared to a year ago. The Camarillo-based manufacturer of microelectronic assemblies eported net income of $189,000, or $0.02 per diluted share, on revenues of $3.8 million for the quarter ending Sept. 30. For the same period a year ago, AML reported net income of $486,000, or $0.05 per diluted share, on revenues of $4.5 million. The company invested in efficiency and cost savings improvements to meet the 50 percent increase in production level anticipated to fill a $3.7 million contract for assemblies used in unmanned vehicles. The production of those components is expected to begin in the fourth quarter. Temporary allocation of resources associated with production on a new program also contributed to lower revenues in the second quarter, the company said. Mark R. Madler
