The first completely full duplex pilot passenger communication with wireless VHF radio transmission in flight.
EQ-1 | complete wireless communications system.
2 x headsets with carry cases
1 x two place 240v wall charger,
1 x communications base station,
1 x wireless PTT
1 x wiring loom to suit radio (must be specified when ordering)
The EQ-1 radio/communications and headset installation has the ability to move in and out of the cockpit without catching wires on controls or projections has been solved completely.
Your comfort level has improved and the quality of your reception and transmissions is now outstandingly clear.
To be able to maximise the system that you are installing, be it an EQ1 or any one of a variety of other wired systems some basic knowledge is required and rules need to be followed---
1. Good CLEAN power supply to your comms AND radio is essential, your battery is the cleanest source of power. ALL your connections must be made via direct paths to this source.
2. Good negative is also essential DO NOT just connect it anywhere on the airframe, connect it to the common negative terminal of the aircraft, these two rules alone will account for most of that crackle in your head (or the receivers head)
3. Good quality connectors on EVERY connection.
4. Correct aerial and matched impedance cable, use 50ohm cable for a 50 ohm aerial-- simple! Correct co-ax cable length is a myth, use what length you need for a tidy installation.
5. A good ground plane for your aerial with the aerial positioned as close to vertical (up or down) as possible and not obscured by struts or a kingpost.
6. Ensure the antenna is tuned for you installation for optimum performance.
7. Give your wiring room to move, no stretched connections, leave a small loop or sag to take up any vibration or movement then cable tie the rest securely.
8. Keep your headset connectors clean, a quick wipe of the connectors with a rag and a ‘hint’ of ‘Brasso’ works wonders in removing the oxides that build up on those old style connectors.
9. Match the headsets with the comms, match the comms with the radio and match the radio with the aerial. The only way to do this is to speak with the relevant manufacturers and ask the question of which components have been tested and are shown to be compatible to theirs.
This last point is the most difficult to achieve if you try using non recommended components. Each manufacturer has their own quirks that seem to befuddle the most experienced avionics expert when faced with the task of marrying equipment.
A high noise environment will tend to aggravate the problems so the attention to the above rules is a must for best system operation.
The EQ1 installation is relatively simple.
- The base unit (comms box) is lightweight and can be positioned anywhere under the dash using Velcro.
- Three of the wires from the supplied wiring loom are then connected to—power, negative and master switch.
- The remaining plug is plugged into the radio (and will supply clean power to the radio) -- THAT’S IT three wires and plug it in: its now installed.
The PTT is wireless and one or multiple PTT’s can be positioned anywhere convenient.
Microlight pilots will Velcro one on the control bar and instructors will want one on the training bars as well.
The EQ1 is a full duplex digital wireless system designed from the ground up using over 20 years military RF design technology experience.
High quality microphone using digital processing to reduce background noise.
System is designed to interface correctly for each radio manufacturers idiosyncrasies.
Incorporates 4 microphones and uses active noise reduction (ANR) technology for extreme noise aircraft.
Complete wiring loom supplied with various plug in options to suit various interface requirements 1.e.; handheld radios.
Adaptive frequency hopping technology at 2.4GHz. (NOT blue tooth)
Voice is digitized and compressed before being sent across the RF interface.
The system uses TDMA protocol like GSM phones to achieve multi-channel full duplex operation.
VOX system is adjustable by user to adapt to personal environment (no clipped words)
‘SOFTVOX’ enabled to allow for short gaps in voice data.
‘VOX MIC’ protocol used to remove non speaking party from radio transmissions
PTT overrides headset VOX for instantaneous radio transmission
The Base Station (small lightweight unit 125mm x 80mm x 23mm) receives and transmits information to headsets, this is the heart of the system and can be located anywhere out of sight attached with Velcro.
The system also has full voice synthesis capability and can ‘speak’ many different messages and control information; all configurations are done this way (voice prompting). This can be expandable to a choice of languages.
Audio personalised aircraft identification.
Advanced features include, multiple wireless PTT adaptor and automatic audio routing for various situations, 1.e. passenger mic lock outs, MP3 input muting etc.
The external base interface (audio) is full programmable as far as level goes and can hence interface into multiple systems, it also has some expansion and control capability (RS232 and switching). including interface for SkyDat glass cockpit instrumentation for audio warnings on engine parameters being exceeded.
Long life NiMh rechargeable battery including voice announced capacity and low battery warnings.
Auto off function-- headsets will turn off automatically after end of flight.
VHF and UHF (VHF override) operation
No wires to tangle or break. Simple & easy to install
Emergency power back up for ‘fail safe’ operation
Built in battery charger or 240v mains and 12v car chargers with voice announced percentage of charge
Can be charged from the aircraft with auto off when charged.
Wall charger will charge to full then trickle charge indefinitely- this means never having a flat battery after a long break from flying.
Software upgrades via internet.
Headsets can be used independently from the base unit and can operate ‘peer to peer’
