Business Radio Hire
Business Radio is the next step up in performance and security from license free solutions like PMR 446.
I can provide Business Radio equipment for hire on "Supplier Light" channels to customers in Norfolk and Suffolk in the UK under my OFCOM license including:
- Motorola UHF Digital/Analogue PMR repeater
- Up to 10 Motorola DP3600 professional grade UHF Analogue/Digital radios
- 4 TYT/Retevis branded VHF and 6 UHF Analogue/Digital Radios
- Vertex-Standard VHF PMR repeater
- 5 Retevis VHF analogue PMR radios
- 12 Retevis UHF analogue radios
Short term radio hire rates are £12 per day for Motorola, £10 per day for TYT Analogue/Digital radios and £3/day for analogue radios. Repeater Hire starts at £75 per day for analogue FM and £100 per day for DMR digital. Please contact us for long term hire rates and radio accessories.
A trailer mounted base station mast is available for hire at £75 per day.
WiFi and Cellular
We can design, build and install cellular to wi-fi gateways for remote and rural locations and have two complete self contained battery powered routers for use at open air events which are able to operate in locations where phones and payment terminals would have poor coverage. Hire is £50 per day plus cost of SIM card(s).
Radio Related Services
We have both Rohde and Schwarz and Marconi test sets and can carry out functional testing and performance measurements on most analogue and some digital radios up to 1GHz and can program Motorola, TYT, Retevis and some other brands subject to software availability.
We can carry out OFCOM commissioning tests on VHF FM Broadcast stations up to 100 Watts output using a RIGOL spectrum analyser with a current calibration certificate.
We can install and test broadcast and communications antennas from 1MHz to 3GHz.
I am a licensed radio amateur and can test all of the major brands of transceiver and may be able to carry out repairs if parts and manuals are still available.
Work is carried out on a time and materials basis at £30 per hour plus cost of parts and materials.
Theatrical Prop Hire
We have a significant collection of historic military and amateur radio communications equipment and are open to hire opportunities and technical advisory roles for film, TV and theatre prop use. Price on application.
Technical Consultancy
IP and Computing
I have 37 years experience in the telecommunications and IT fields with BT covering everything from IP networks, the beginnings of commercial VOIP and online computer games, Datacentre construction and operation, and Digital TV to Satellite communications. I have at various points prior to my retirement from BT been a Chartered Engineer a Chartered IT professional and held a Cisco CCNA certification.
I am available for consultation on network configuration and design and to deliver network training. Most of my recent experience has been with Cisco and Checkpoint equipment using BGP, EIGRP, PIM in datacentre and WAN installations.
I have experience since the 1990s building web sites having started using old school raw HTML and CGI and more recently using AWS and IONOS cloud based services and can advise on cloud migration from personal experience.
Radio
We are able to do radio coverage surveys for the VHF and UHF bands.
We are able to do spectrum occupancy surveys from 1 to 2500MHz and interference monitoring or investigation and tracing within the capabilities of our test equipment. This work will be done on a time and materials basis at our consultancy rates.
Frequency Control
I still hold stock of the Epson SG8002 programmable quartz oscillator and can provide programmed examples until stocks are exhausted.
The SG8002 comes in a 4 pin J-Lead SMT package slightly larger than a classic 8 pin DIP so easily hand soldered and can be programmed for frequencies between 1.5 and 125MHz with 3.3 or 5 volt supply, and optional TTL or CMOS squarewave outputs.
