Can a VHF DSC Radio give out their position and other inof when polled from ashore?

No, you cannot automatically poll position information from other DSC users in the current system.  A new system (backwards compatible with DSC) called Automatic Identification System may be capable of this.\n\nThe primary purpose of DSC was to provide a means for one marine VHF station to specifically contact another while keeping the speaker muted during other unrelated radio traffic.  The positioning transmitting capability was added as part of an automated distress calling feature.

ADF's detect an electric field and a magnetic field which are perpendicular in space and their amplitudes vary sinusoidally with time. The magnetic field induces a voltage into the windings of the ADF loop antenna. By measuring the phase difference between the windings the ADF is able to determine the direction of the beacon. \n\nPutting beacons around the house and using ADF to navigate turns out to be expensive and inefficient as GPS and proximity sensors are available and work better.

I don't think it has that functionality yet, that is why it is still on Beta. Try sending it to the Community forum on the top right of the page.\n\nI would also suggest using the ROAD view and then estimate the addresss by going to the same site in Google map or Google Earth.

for the boeing B777-400 they have communications and navigation antennas:\n\n\n1.  3 -VHF antennas - communication \n2.  1 HF antenna      -communication\n3.  1- SATCOM        -comm./navigation\n4.  2- TCAS antennas - navigation\n5.  6- EGPWS antennas -navigation\n6. 1-RADAR antenna     -navigation(mostly weather forecast ahead)\n7. 2- DME antennas   - Navigation\n8.  3- glideslope antennas - navigation during landing\n9.  2-ATC antennas -navigation to prevent air collision\n10. 1- VOR antenna - navigation\n12. 2- Localizer Antennas - navigation\n\nsome more which I might have missed, but this are most of them.

You can set the band of your radio to SW or short wave. Start tuning. You will get many international channels. The clarity will be poor though. Satellite radio is the best.

Sure.  An oscilloscope ought to do the trick.

you can use a fm modulator

In this situation a compass needle will not point to anywhere on the dial very strongly - it will just wander around weakly with no real direction. Explorers now need GPS to determine the exact pole location; it shifts slightly every year.\n\nDC :-)

Your transmitter will work, your receiver won't.\nbut you could bounce the signal onto a simple solar cell\nconnected to a set of headphones and you should be\nable to receive a weak signal...\nYour receiver won't work because light won't move the paper and the grains of sand.....

Radio shack has a book (about $20) that has every freq you could ever need in it , even your local #'s

There is often a wide divergence between theory and application.  I remember one application where lengthy mechanical linkages and cables were used to transmit rudder position for a huge seagoing ship in the even that the steering gear room became flooded (and electronic indication was lost).  The system had too much lost motion to indicate rudder position even though it looked good in theory.  I suggested connecting a vertical rod to the rudders that pierced the overhead into the ("unflooded") compartment above which could be connected to a reliable electronic transmitter (similar to existing "flooded" transmitters) and that worked much better.  Even electronic control systems can exhibit unexpected hysteresis when built.

WHAT ARE YOU LOOKIN FOR? IS IT THE HARDWARE TOWER ANTENNA, TRANSMITTER/ RECEIVER , DISPLAY??????\n\nWhat specification\n\nWhat are they looking for is it a weather radar or is it a navigation radar.  IS is used for landing aircraft aboard the rig?  Is the rig on the land or is it in the water.  Is the rig in the Gulf of Mexico or is it in the North Atlantic. If it is in some body of water what body.  If it is land bound where?  Is it within 150 miles of an airport?\n\nWhere is the rig located and what does the radar need to see?  Is it for the Weather or Aircraft?\n\nWHAT IS THE FUNCTION OF THE RADAR ON THE RIG IF IT IS AN OIL DRILLING RIG???\n\nWHAT DOES TEXACO NEED RADAR FOR ???\n\nBe glad to help \n\nAPS

People say 'save our ship' or 'save our souls'.  But really it's just a easily recognizable morse code sound.   dit dit dit dah dah dah dit dit dit.  It's easy to pick up without paying direct attention.
