radio scanners
« on: August 06, 2007, 05:53:23 pm »

Currently own two - GRE's - PSR 295 (which does most of what's out there but bought specifically for Military Airband) and a PSR 282, which does Civvy airband and good on marine VHF.

Was the proud owner of many HF sets as a listener, the last being a Grundig Sat 800 which was sold six months ago.

Any others into 'scanning'?

Coast Guard VHF and Cape Cod Maritime VHF listener here. Anybody can listen online. In fact right now there is a report of "ref flares" and "all boats are instructed to keep a sharp look out" DSC alert received (boat in distress)...i hope they are ok...

Weeds,

Thanks for the PM. A full list of US Marine VHF channels is here:

http://www.navcen.uscg.gov/marcomms/vhf.htm

Usually, a scanner will either come with simply channel numbers eg 01 and you have to manually input the frequency you want stored on it. For example Channel 1 could be used as Marine Channel 16 - 156.800. Modulation is FM.

Some scanners will show the frequency readout. eg. Mine is 'banked' with mil airband, civ airband and marine VHF. I have VHF Channel 16 Marine on my channel 40 though the readout shows 156.800 FMN (FM Narrow). I also have a dual watch so that, if I program it, it will pick up two channels by scanning both. I make one usually Channel 16 and the other our primary lifeboatr working channel (also HM Coastguard) which is Channel Zero (156.000). I can also make a priority frequency the 'select' one so that if it is scanning, then the priority will come in every two seconds, but lock when it gets a signal.

If you want to say what scanner you have I may be able to help further.

The UK does not allow re-broadcast of marine VHF but I have got links for the Dutch system, which also uses AIS so you can hear and 'see' the ships on an auto- refresh map. It is situated here:

http://www.scannernet.nl/AIS%20Google%20Online%20DSC.html

and here: http://members.home.nl/krid/livescanner.html

There is an AIS map of the US at: http://ais3.siitech.net/VTSLite/AView.aspx but I don't think it has VHF - but you could use a map which shows ships movements (known as AIS) and listen to your scanner at the same time?
