Micro-Tel
Micro-Tel was an electronics company based in Hunt Valley, Maryland (US). It was established in 1962 by Dick Finke (later with Bill Richardson). The company specialized in high-end microwave receivers that were mainly intended for the US Goverment and the US Department of Defense.

The company was built on the foundation layed by Richard S. Finke in 1962 when he started his own company. Being educated in electronics during WWII, he had build up a strong reputation and began developing equipment for the DoD.

By 1972, he had teamed up with Bill Richardson to become one of the most important pioneers in the world of defence electronics. Together they founded Micro-Tel Inc. and settled down in Hunt Valley, Maryland (US) where in 1982 they built a brand new 30,000 square foot facility for 2.6 million US$; quite a lot of money in those days.
  

Micro-Tel became well known during the early 1980s for its range of microwave receivers, such as the PR-700 and the MSR-901. In 1989, Micro-Tel was taken over by M/A-COM, which in turn was taken over by Tyco International Ltd. in 1999. Under Tyco, Micro-Tel M/A-COM became the worlds largest producer of microwave components and equipment for the defence industry.

In 2008, after a series of complaints against Tyco International about fraude and bribery in Saudi Arabia, the M/A-COM SIGINT division was sold to Cobham and is currently known as Cobham Advanced Electronic Solutions (CAES). They are no longer based based in Hunt Valley (MD, USA).

History
The history of Micro-Tel starts with Richard (Bill) S. Finke, a native of New York City, born on 31 March 1923 and educated at schools in the Forest Hills area. When America got involved in WWII in 1941, Finke was 18 y.o. and studied Electrical Engineering at the New York University.

In 1943, at the age of 20, he earned a degree in Electrical Engineering from New York University. Shortly afterwards he joined the Army where he became an officer in the Army Signals Corps. He spent most of his time during World War II in Europe. After the war, he started working for the US electronics company RCA Corporation and later for the Central Intelligence Agency (CIA).

Micro-Tel Corporation
In the early 1950s, Finke moved to the Baltimore area where he worked for Martin Marietta Cor­poration and the Bendix Communication Division, until he started his own company in 1962. The company became known as Micro-Tel Corporation and specialized in microwave receivers for the US Department of Defence (DoD) and for various US domestic intelligence agencies.

Micro-Tel Inc.
In 1972, Bill Finke met Bill Richardson and together they set up Micro-Tel Inc. As they wanted to expand the company, they moved to Hunt Valley, Maryland (US). At the time, they were one of the first technology companies to settle down in the area, which has since become one of the region's most important high-tech hotspots.

Adams-Russell
In 1978, Micro-Tel merged with Adams-Russell and was eventually renamed Adams-Russell, Micro-Tel Divi­sion (1981). The image below shows the Mirco-Tel asssembly workshop in July 1980, with President Dick Finke and Bill Richardson behind some of the company's equipment.


Plans were made for a new premises for which they started rasing the necessary fun­ding in the middle of the recession of 1980. Below is an artist's impression of the proposed building.


In 1982 a brand new 30,000 square foot facility was erected at Gilroy Road for no less than 2.6 million US$. In this period, Micro-Tel became best known for their range of microwave compo­nents, measurement receivers and intercept equipment, with their typical faint mint colour.

Even­tually. Dick Finke sold his shares in the company and retired. In 1989 he moved from Towson to Oxford (US), where on 28 November 1992, at the age of 69, he died of a heart attack [1].

M/A-COM
In 1989, Micro-Tel was sold to M/A-COM Inc., a Public Company from Burlington, (MA, US) with a desire to expand. At that time, M/A-COM had well over a 1000 employees and was growing rapidly [2]. With the acquisition of Micro-Tel they hoped to expand their business in microwave equipment and components for the defence industry. In early 1999, Micro-Tel was renamed M/A-COM SIGINT Products and that same year they won a US$ 3.5 million contract to supply an unknown number of microwave receivers to the US Department of Defence (DoD) [3].

Tyco
Shortly afterwards, also in 1999, M/A-COM was taken over by Tyco International Ltd., a Swiss-based electronics giant that had acquired many companies over the years, in order to increase their global market share. As a result, Tyco became the worlds largest supplier [4] of advanced microwave electronics for the defence industry with over 3500 employees by 2006 [5].

In 2006, Tyco reported a sales turnover of 12.7 billion US$. Later that year however, the tide turned when Tyco was accused of accountancy fraude, tax fraude, and bribery [6][7]. Several complaints against the company were filed under the Foreign Corrupt Practices Act (FCPA), mainly related to a Tyco subsidary in Saudi Arabia, resulting in a settlement of approx. 30 million US$.

Cobham
Following the 2006 fraude case, M/A-COM was moved from Tyco International (Switzerland) to Tyco Electronics (Florida, US), but to no avail. Investigations revealed that the fraude had con­ti­nued even after the settlement in 2006. Finally, on 13 May 2008, M/A-COM, and hence SIGINT Products (which had nothing to do with the fraude), was sold for US$ 425 million to Cobham Defence Electronics, one of the largest defence contracters in the United Kingdom [8].

The microwave products division (i.e. the former Micro-Tel) became a separate business unit of Cobham Defence Electronics, known as CDES SIGINT, and was still located at the old address in Hunt Valley, Maryland (US) in 2013 [9]. A quick search on Google Maps reveals that the building at 10713 Gilroy Road has hardly changed since 1982. Apparently it is currently abandoned (2015).


Advent International
On 17 January 2020, following approval from the UK Government and security guarantees by the buyer, Cobham was taken over by the American private equity firm Advent International for GBP 4 billion [12]. Immediately after the acquisition however, Advent started divesting most of Cob­ham's sub­sidaries and business units. 18 months into the deal, they had already sold the bulk of Cobham's operations to other buyers, leaving no manufacturing operations in the UK.

CAES
In 2021, the former RF division of Cobham became Cobham Advanced Electronic Solutions (CAES), with is a standalone US national company with an independent board of directors [13]. In November 2024, CAES became part of Honeywell International Inc. [14][15].

Impressions
One of the first people to be hired by Dick Finke and Bill Richardson after they founded Micro-Tel Inc. in 1972, was Fred Markle who eventually became the lead design engineer. The image below shows Markle in front of one of the radio systems he designed. It is part of a series of three pho­to­graphs from Markle's estate, that were rediscovered by his son Jody in early 2025 [16].


The photographs, that were in a deplorable state when they were rediscovered and had signi­fi­cantly faded over the years, were colour-correct and digitally enhanced at Crypto Museum.
