One DTB NSME ground transponder and two RCA airborne DMEs distance measuring equipment were modified to provide equipment suitable for in-flight evaluation of the findings of the report entitled, Accurate DME for Use with ILS. AD-427 721 The modifications consist chiefly of reducing the pulse rise-time, providing two-mode I-F amplifiers to provide wider bandwidth to pass these pulses while maintaining high selectivity, change the timing to the first pulse of the coded pair, provide a constant reply prf which is independent of the number of interrogating aircraft, and preserve the compatibility of the ground and airborne equipments to provide service with unmodified equipments within the VORTAC system.
