Wg Cdr Shabda Prakash Tewari has been working as Officer Commanding of one of the Repair and Maintenance Units since 29 Sep 88. His efforts to keep the old radars in usable condition have positively enhanced air defence capability of South Western Air Command.

Wg Cdr Tewari successfully undertook several projects which enhanced the operational efficiency of the Indian Air Force. Trial modification of radar warning receiver has been successfully completed. This modification has been called 'Force Multiplier' by the CAS. The modification has been accepted by Air HQ for incorporation. Wg Cdr Tewari has also developed two modifications on MiG-23 to provide digital indication of height and time to the pilots.

During 1989, component level repair facilities for printed circuit boards (PCBs) of HF sets used by MOF have been set up at one of the RMUs. Integration of Russian made communication systems with mobile tropo system has been made possible after incorporating some modifications at the RMU. This has enhanced communication capabilities in SWAC.

For his outstanding contribution to improve operational efficiency of the Indian Air Force, the President is pleased to award Vishisht Seva Medal to Wg Cdr SP Tewari.

Warrant Officer Gour Babu Sharma was on the posted strength of a Repair Maintenance Unit since 01 Apr 86.

WO Sharma while carrying out all routine on-site repairs and laboratory tasks involved himself with setting up repair facilities for repairing PCBs of HF R/T sets and other ground based communication and navigation equipment. So far facilities have been set up for repairing about 25 types of PCBs and a large number have been repaired using these facilities during the preceding one year.

DRDF of a flying Wing experienced most unusual interference phenomena which could neither be explained nor rectified by concerned technical personnel using conventional diagnostic techniques. Air HQ entrusted this task to the RMU and WO Sharma took up the challenge. He meticulously studied all other electronic emissions in the area and analysed their impact on the DRDF. This was a major feat requiring original thinking and thorough knowledge of modern electronics and earned appreciation for the RMU from Air HQ and HQ SWAC.

For his exceptional professional skills, contribution towards improving the operational efficiency of our airfield facilities, the President is pleased to award Vishisht Seva Medal to WO Gour Babu Sharma.
