Mr. Wolfson and his crew were recognized by Rear Admiral D.B. McKinney NAWCWPNS Commander when they were presented with a NAWCWPNS Team Award for their accomplishments with the HAWK.
It read in part “You accept the massive challenge and worked within your own job description to learn the logistic field to acquire parts locate technical manuals and track all leads necessary to enable the system to work. You accomplished this under a very primitive and adverse working environment; outdoors in the wind and other severe desert conditions, adapting and creating tools and equipment as needed. The speed with which you restored the radar and your efforts to keep the cost low saved the government in excess of $1.2 million.”
January 1993 I was summoned to the office of the Division Branch Head to talk about my previous experience with the HAWK missile system. He informed me that ECHO Range will be taking delivery of a PIP II Hawk System from Letterkenny Army Depot and asked me if I would take the Team Lead Position. While waiting for delivery of the HAWK system he asked me to look at some problems the Roland ADA System was having with their Target Tracking Transmitter. To make the Roland ADA system mobile and fast reacting the system was designed in a modular fashion like a fighter aircraft, to trouble shoot the radar and fire control systems while installed in the system was impossible. While studying the system schematics I discovered that the system was designed to be serviced at a purpose built Test Station with the necessary power supplies, and inputs to operate the Transmitter. The Transmitter was also designed with test points that were brought out to the interface connector that was monitored at the test station. As a result of my research into the Roland Transmitter I was able to design a Roland TTR Transmitter Test Station. I scrounged enough test equipment, power supplies, salvaged some op amps and modular reference power supplies to build an interface panel. The TTR Transmitter was completed, tested and put into operation May 1993.

That's it for the highlight, now for the boring stuff
Repair and Calibration at Kratos Defense and Security Solutions
To maintain obsolete Foreign Military Systems I was tasked to bring vintage test stations out of storage, repair and calibrate the test equipment.
Repaired multimeter and checking calibration. The laptop uploaded data from the oscilloscope and I created files that were used to certify calibration of the multimeter.
Just finished repairing an HP Function Generator and checking calibration. The laptop got data from the oscilloscope and I was able to download the display in files which were used to certify the Function Generator as being fully functional and meeting calibration requirements.

Laptop display that will be saved with text as to all parameters of all three Oscope traces.
The test equipment I repaired and calibrated went into this circuit card test station.

I'll skip the time I was in Egypt with Raytheon, Yes I took a lot of pictures, but Cameras were not allowed in the Depot, so no pictures of my work there.
My shop at Donna Ana Missile Range with Kratos Defense and Security Solutions. I had two HFC Consoles used for repairing HAWK modules. Shown is the oscilloscope connected to the console for checkout.

Worked with Instrumention support Branch on the North Ranges to help them get their HAWK Radar AN/MPQ-46 functional.
LOL Really enjoyed this test, don’t know how much I can say about it, but I can say we didn’t make it easy for them.
Through contacts at the Air Defense School at Fort Bliss I was able to arrange training classes for the latest version of HAWK which was the last class in HAWK at Fort Bliss Texas. Also worked with ARM Target group on the North Ranges to help them get their HAWK System functional, and also helped them locate needed spares and Technical manuals.
Jan 86 to Sept. 91 I was assigned to Environmental Test Section Code 62122, as Instrumention Engineer. I worked with Test Instrumentation such as Endevco Charge Amps, strain gauges, thermocouples, computer-embedded process controllers, and Ling and Unholtz Dickey Shaker systems. Designed and built the SSPA test set, this test set is used to test and repair the Ling Electronics Solid State Power Amplifier (SSPA) modules used in the Ling model SSPA 48 and SSPA 96 High Power Amplifiers used to drive the Ling Shakers that are used for Vibration testing.
Because of the modular construction of both the SSPA 48 and SSPA 96 High Power Amplifiers, troubleshooting the output modules was impossible. The modules were installed vertically in groups of 8 modules; there were only two inches between modules. The Emitter and Collector Bus leads were in a wiring harness and connected to the front of the modules, the module cooling hoses with the audio (3M) connector connected from the rear of the modules. The modules could not be extended from the bay for troubleshooting purposes because of the way it was installed into the bay.
The Ling Model 8096 and 8048 Solid State Power Amplifier (SSPA) is a high power, water-cooled audio amplifier specifically designed to provide the necessary power output to drive an electrodynamic shaker for vibration testing applications.
The purpose of these amplifiers is to amplify sine, random or shock wave signals in a variable audio frequency and amplitude range. The modular construction of the Ling Solid State Power Amplifier (SSPA) permits a wide selection in the number of output modules to be used in a particular amplifier, thus providing a wide variation in total output power.

June 85 to Jan 86 Kentron Int M.S.S. 690 Meteorological Sounding System. I was hired to find the problem with the system. Discovered that the problem was in the raiosondes. Designed and built test set to repair and calibrate the Sondes.

My work at Laurel Mountain (CA) with Kentron Int
I worked with everything on the mountain. The radar which was an AN/FPS-20 Heavy Ground Search Radar. The microwave communications, Air to ground radios, and even the chemical toilet which broke down often. I worked here from 1985 to 1986 Seen in the picture, Data converter that converted analog data from the radar to digital data which was transmitted via RLM-4 Microwave Link to Edwards AFB, and China Lake Mission Control.

June 1983; AN/TPQ-39(V) NIDIR. Variant of the AN/TPQ- 39 radar, uses antenna pedestal of the Nike Hercules TTR, MTR, or TRR Radars; 11 built 1974 to 1979 1983. My first job at China Lake Naval Air Warfare Center, was to help build one of these Radars.
September 1979; operated and maintained the 469L Corts telemetry station. Responsible for maintaining closed circuit television system associated with the telemetry station and local radar. Also responsible for the maintenance and repair of the local Terracom Microwave units and UHF and VHF Ground to air Radio sets.
At times I would also fly out to remote mountain sites via Air Force Helicopter to resolve problems with equipment such as Radar Borsite Tower, Microwave relay station, or HAMOTS (High Accuracy Multiple Object Tracking System) station.
My first job after I got out of the Army. Digital Instrumentation Radar (DIR) AN/TPQ-39 (V) The Radar was not functional, I repaired the Radar and it was turned over to the government to be used during the Crusie missile flyoff. Tracks flying targets in either skin or beacon modes for the gathering of positional data. The heart of this radar was the Data General minicomputer, Nova 800. Also responsible for the repair and modification of the Milgo and Variplotter Poltboards, and Brush instruments chart recorders.
