Who are you and what do you do?
Chris Angove has had a passion for electrical and electronics engineering from an early age. He owns and manages Faraday Consultancy Limited (FCL). FCL provides professional
engineering support to client companies across many sectors including: RF, microwave, analog, high-speed digital,
broadcast and communications, telecommunications, radar and defence systems engineering. FCL and Chris Angove support clients' projects from hands-on circuit design through to major systems and everything in-between. FCL is registered in England
and Wales (registration number 2938426).
How can you help my team/project/company?
In today's environment, teams are routinely faced with challenging project timescales.
Promises made must be met, otherwise personal
commitments, the company's reputation and peoples' jobs may be at risk. FCL can provide valuable support to these companies very quickly and effectively. FCL may well have already achieved similar objectives with other clients.

Who is this guy Chris Angove?
Chris has always been very interested in electrical and electronics engineering. He was brought up in Cornwall and went to The Humphry Davy Grammar School. After completing a telecommunications course he was seconded to the Dubai Satellite Ground Station, United Arab Emirates. There he was on the
24-hour duty engineering team and performed regular maintenance and installation activities on
the live international telecommunications equipment. The
hardware included C-band liquid nitrogen cooled low noise amplifiers, satellite receivers, modulators, upconverters, high power
amplifiers, uninterruptible power supplies, control/monitoring hardware and the antenna tracking equipment. His
duties covered maintenance of the station down to the
three phase solid-state inverters, diesel generator sets, air-conditioning plants, temperature
and humidity recording. He also supported planned maintenance at the nearby terrestrial back-haul site: VHF/UHF terrestrial links, microwave line-of-sight links
and cable terminal equipment.
Between shifts he chose to study and
to further advance his understanding of satellite communications and the broader aspects of electronics and telecommunications.
When he returned to the UK he became a sponsored student on an honours degree (thin sandwich) course in Electrical and Electronics Engineering at The City University, London, completing it with an upper second, supporting his career in electronics, communications and radar engineering. Shortly afterwards he successfully completed an MSc in Microwave and Optical Engineering
at University College London. Since then he has held several senior
engineering positions with respected leading corporates. He has been operating as an independent professional engineer for several years and continues to support clients in various contract roles.
Can I have a copy of Chris's CV?
Certainly. Please contact Chris directly on +44 (0) 7989 305995. He will delighted
to send you one and to explain how he believes he (usually represented by FCL) can help you. To elaborate
on his skills and experience and to answer any questions you may have, he will be very pleased to meet you at a time and place convenient to you.
Evidence of all the qualifications shown on the CV can of course be
Why should I use your services instead of those from company X?
Every contract has been a success: objectives and specifications met and exceeded, documentation delivered and a comprehensive set of indexed and referenced records
and documents left with the client. Most contracts to date have started at 6 months or more and many were
But eventually of course all contracts have to end and Chris is delighted to have worked with all clients and has made many friends. People with these skills and experience are relatively few so names and reputations are remembered. In the case of FCL they are remembered for their
hard work, reliability, adaptability and the consistently high level of professionalism delivered throughout. FCL is also delighted to have supported
several clients on more than one occasion.

What about note keeping and documentation?
FCL follows the record keeping and documentation requirements of the client. Usually a traceable engineering log book, physical or electronic, in which is recorded: day to day work notes, equipment setups and serial numbers, contact details of suppliers, sources of information (references to websites, textbooks, papers,
equations etc.); test results summaries and calculations. This is left with the client at the end of the contract. FCL's default policy on note keeping is to record
sufficiently detailed notes in such a way that tests, investigations etc. can be repeated
reliably at a later date, perhaps after the contract has ended. FCL has received many positive comments about the
detail and quality of both its routine note keeping and the formal reports
that it has produced.
FCL regards the production of quality documentation as an essential part of its services to the client. FCL's documents are relevant, concise, free from rambling,
repetition and unnecessary words. Opinions are not expressed without reliable evidence that the reader may follow up. Perhaps with the exception of Ohm's Law, no formula or assertion is stated without
references to reputable sources. FCL maintains high skill levels of the industry standard word processing, spreadsheet, graphics, drawing and other applications to support the necessary documentation. Clients' deliveries routinely include well written and correctly configured and reviewed documents, accceptable to the customer. FCL has experience in writing most types of deliverable documents (requirements, design proving, test, acceptance) for many types of equipment.
How can we be sure that we will retain the skills and
knowledge gained whilst you are supporting us?
The client will benefit both from the skills that FCL has built up working in similar industries elsewhere and from the continuous R&D work FCL
engages in to prepare for future contracts. On most contracts one of the client's senior engineers
or project managers works directly with FCL's representative to ensure that the best possible support is given. FCL will work with him/her to ensure that everything required is transferred, hardware demonstrated, questioned answered and all documents supplied.
How can I be sure of confidentiality?
FCL respects the clients' proprietary work and always assumes the highest level of confidentiality. It will never release any of this information elsewhere without the explicit and unambiguous written permission from the owner. FCL is happy to sign any reasonably worded confidentiality, non-disclosure or similar agreement with the client.
What is your company philosophy?
To continuously and consistently deliver the highest possible professional service.
Do you provide services directly or through a third party?
Either. If either the client contacts FCL directly or vice versa, and this results in FCL providing the client with services, FCL will
normally invoice the client directly. An exception might be in the unlikely event that FCL has a current exclusivity agreement with a particular third party relating to that client.
How much will you charge?
A competitive market rate. This would normally be delivery-based because FCL works on a business to business basis and FCL can offer increasing discounts for a longer engagements. The savings in time and travelling expenses for all off-site work will be passed on to the client
by way of a reduced rate. These will also reduce the client's costs, reduce traffic congestion and reduce pollution. There will be less environmental damage and extra available time to
support the client which
would otherwise have been spent travelling.
Can you give me more details on your work with client X?
The details of FCL's work with all clients are strictly confidential, even if no formal confidentiality agreement has been signed. If a prospective client wishes to contact one of FCL's previous clients, this may be possible once permission is given.
What facilities do you have?
FCL runs a laboratory equipped for electronics design and development work
currently up to about 6 GHz. For higher frequencies, test equipment is
hired as required. The actual equipment used would be determined by the client's requirements and agreed with the client before starting the contract.
What policies do you have in place for protection of the environment?
FCL supports many policies to protect the environment, including the following:
- Using public and other energy efficient transport instead of car travel, wherever this is possible.
(For two contracts extending to more than 3 years, the transport for
travelling to and from the client's site was a bicycle.)
- Working with the client to allow possible travelling during off-peak
- Maintaining a 'minumum printout policy'.
- Adopting an in-house repair policy for electronic equipment.
- Donating obsolete but serviceable equipment for educational purposes.
- Recycling electronic components for development work.
- Avoiding unnecessary travelling to meetings where the process can be undertaken by email, telephone or teleconference.
