HF3W SSB Receiver - Nasa Marine Instruments (2024)

For a yachtsman planning a voyage, the ability to predict the weather is essential.
The rate of change of barometric pressure and history of wind speed can be an invaluable indicator of imminent conditions.

Many sailors rely on low cost domestic barometers, which are inaccurate, have low resolution and very poor history. Several quality paper recording instruments exist but are delicate, fiddly to use and rely on paper which can jam when damp. The MeteoMan overcomes all these problems. It provides an accurate, high resolution barograph recording in excess of five days data on barometric pressure and wind speed. It is easy to use, reliable, rugged and draws very little power from the boat’s battery.
The Meteoman is available with an optional NMEA Wind sensor which provides wind direction, wind speed and external temperature. The Meteoman provides reliable meteorological information for the yachtsman. The main display shows the wind speed and direction, the ambient temperature and the barometric pressure.
To assist in predicting future trends the unit also displays a precision barograph and an anemograph showing barometric pressure and wind speed for the previous five days.

In addition to the meteorological functions the unit includes a marine chronometer, a stop watch, a race countdown timer, display of internal temperature and battery voltage.

MeteoMan can be connected to an NMEA Clipper Wind system where it will get wind speed/direction data via the Clipper wind output.

NMEA Wind Sensor supplied with mounting brackets and 20 metres of two core screened cable.
NMEA 0183 sentences: Wind speed/direction MWV Temperature XDR

The new bluetooth Navtex is a dual frequency Navtex receiver that decodes and stores Navtex messages for viewing on an Android bluetooth enabled mobile phone or tablet. The unit is designed to be run continuously and have the stored messages downloaded as and when required by the user. An android app enables the user to search the stored messages or to program the device to display only wanted message types from selected stations.

The internal memory stores in excess of four hundred typical Navtex messages with new messages overwriting the oldest.The receiver can be supplied with a standard E-vector antenna or, for more challenging conditions, an H-vector antenna is also available. The H-vector antenna has a standard 14 tpi mount and is connected to the receiver using the seven metre cable provided. It can be either surface of rail mounted and there are several suitable, optional mounts available. A fused power cable is also supplied to connect the receiver to a permanent 12 volt power source.

The android app can be freely downloaded from the google play store

The Target Navtex Pro is packed with features yet is still remarkably easy to install and use. Great care has been taken to make this unit very simple to operate, in fact should one lose the comprehensive instruction book supplied with it, it is possible to program the unit via the on-screen menus – it really is that simple. The messages are displayed on a high contrast backlit liquid crystal display with a clear line space between messages to aid location – this is necessary as the unit has a very large memory.
You can be sure you always have up to the minute data as the memory will overwrite the oldest messages if it becomes full. However you can at any time erase the data memory if you wish. It is like a continuous stream of paper – without the mess or expense!
Navtex has come of age, a free worldwide information service in English. A Navtex receiver is a most essential piece of equipment and the Target Navtex Pro is state of the art. This excellent piece of equipment comes complete with its own active aerial and is designed to be left on continuously – consuming a miserly 40mA. Can you afford to be without one?

The Target Navtex receiver is supplied with – Antenna and 7 metre cable, a power cable, a crade mount bracket and a manual.

Liquified petroleum gas (LPG) is an invaluable source of energy on many sailing vessels. It should, however, be used with great care. In its gaseous form it is heavier than air and will always collect at the lowest level in a vessel. Any leak of gas, any spillage of liquid could sink to the bilge and, unable to escape, build up to explosive proportions.

The NASA Marine gas detector system warns if the level of LPG rises above 10% of the lowest explosive limit (LEL) giving adequate warning of the need to ventilate the area before a dangerous situation occurs. The system consists of a cabin mounted monitor and a remote sensor. The monitor gives visual and audible warning if gas levels at the sensor rise above 10% LEL and will warn of fault conditions such as damaged cables etc.
The splash proof sensor is supplied with a 5 metre cable and has a test button to check the system right through to the gas sense element. The sense element is user replaceable in the event of contamination. Supplied with power cable.

The BM-2 Compact is designed for larger battery capacities and higher load currents than its BM-1 Compact sister product.

BM-2 Compact is designed especially for applications where space is at a premium. It fully monitors performance of 12 volt lead acid battery systems with capacities of up to 999 Amp hours. The package is supplied complete with a precision 200 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. The unit continuously monitors voltage, current (charge or discharge), number of amp/hours (charge or discharge), the batteries state of charge and the time to charge or discharge. This information leads to more efficient use of the battery, which can enhance battery life and reduce the risk of failure.

The PC Navtex USB is a two channel navtex receiver designed to operate on your personal computer. It will receive navtex messages even without your PC connected. Navtex messages are stored in a vast internal memory for you to download when you get on board. Down loading is quick and the software provided allows you to select the messages you want.
Leave the unit on 24/7 then, when you get on board, just plug in your PC and immediately download the latest weather forecast from your local station, or any other message stored in the PC Navtex USB’s memory.
