In honor of Jack Prawica

D.L.S. was fortunate to have had Jack our as Technical Manager and Wheeling Lab Manager for 29 years. His quick smile and caring attitude, in addition to his technical and management skills, will be deeply missed. Thank you, Jack, for your years of loyalty and dedication and for the skills you have shared with other engineers who will be carrying on your work.

Our engineering staff is accredited by iNARTE, the International Association of Radio and Telecommunications Engineers, Inc. The US Navy, through NAVAIR to ensure that their equipment was being tested correctly, established this program in the late 1980s. This program exists today, with prospective engineers required to take and pass a written certification examination test. Most NAVAIR related programs still require that the testing be performed, certified, or supervised by iNARTE engineering staff.

D.L.S. provides an experienced technical staff of 25 engineers, 18 of which are certified to the iNARTE standards. These engineers are trained not only in test performance and methodology, but provide engineering assistance with respect to compliance failures, offering on the spot troubleshooting and problem-solving experiences. D.L.S. was also awarded iNARTE’s prestigious organizational certification.
