Re: Topband: Strange CW Coded Messages
I seriously doubt it - check the links - they all seem to be crystal based. There are "smart" beacons that respond only when interrogated by the owning vessel. Nowhere is there any indication that these things have any smarts at all beyond that, and the vast majority are set and forget until you come back to collect the net - and their purpose is short range - relatively. The fishing trawler gets within maybe 50 miles and uses ordinary DF to find the beacons... your on freq transmissions are unlikely to bother them. It DOES feel good, tho - once. Most likely is that they went into sunlight and you were hearing them on greyline...

Re: Topband: Strange CW Coded Messages
an experiment to see if a couple of photos will make it through- I shrunk them to be small enough that they might be tolerated - but I suspect they will be stripped off these are two of the fish beacons we found washed up on shore at VP6DX. you can read the freq on one of them 2202 KHz. the smaller one we found actually has a small micro and 3 boards.. in another shot you can read the ID on the PROM- EK92. the bigger one with the D cell stack intact shows Z5 for the callsign. What is amazing is that these two were virtually intact- and were not the corroded pile of electronics you would have expected a pile of D cells for ballast, a buoy with a whip, and a simple CW ID timer, and thousands of miles of sea water and you have QRP heard round the world 73 robin, WA6CDR I tried to find a better link, but here is one on a commercial fishing supplies site http://www.commercial-fishing.net/index.php?option=com_virtuemart&page=shop.product_details&flypage=flypage-ask.tpl&category_id=15&product_id=27&Itemid=179 if that doesn't make it through try http://www.commercial-fishing.net/ and marine electronics Radio Beacon I know nothing about these people, its just the first useful example I found for a source for the beacons we hear Robin - Original Message - From: "GeorgeWallner" To: ; Sent: Monday, June 11, 2012 19:20 Subject: Re: Topband: Strange CW Coded Messages On Mon, 11 Jun 2012 18:37:26 -0400 Herb Schoenbohm wrote: These fish beacons are sometimes very strong and normally out in the Gulf of Mexico.

These fish beacons are sometimes very strong and normally out in the Gulf of Mexico. I just wish I could replicate the QRP transmitter and antennaor is it just the saltwater ground?

Re: Topband: Strange CW Coded Messages
These kind of beacons are common for use at the starting end of long lines set by commercial fisherman so they can locate and retrieve the long lines sometimes as long as 50 miles commonly set for sword fish and tuna he off the east coast and surely everywhere else FYI also one that is commonly hear on 1850 ssb is one that ID's "AD3" Sam -Original Message- From: topband-boun...@contesting.com [mailto:topband-boun...@contesting.com]On Behalf Of Milt -- N5IA Sent: Monday, June 11, 2012 4:50 PM To: Mike Waters; gali...@comcast.net; topband Subject: Re: Topband: Strange CW Coded Messages For those that are interested in what one of these units looks like you can go to https://bmoran.onehub.com/fishing-beacon-pictures/pages/files There is a group of my photos, taken on Ducie Atoll, of the fishing beacon which Robin, WA6CDR and I found while installing the Beverage antennas at VP6DX. de Milt, N5IA -Original Message- From: Mike Waters Sent: Monday, June 11, 2012 1:02 PM To: gali...@comcast.net ; topband Subject: Re: Topband: Strange CW Coded Messages Those blasted illegal fishnet buoy transmitters are in use all over the world.

Re: Topband: Strange CW Coded Messages
Hi Joe, There was quite a bit of discussion about fishnet beacons here a year or two ago. If you search back through the Topband archives, you might find your answer. http://lists.contesting.com/archives//html/Topband/ A couple of web sites had a list of them. What antenna did you hear them on? Your 140' BOG or your inverted-L? 73, Mike www.w0btu.com On Mon, Jun 11, 2012 at 10:22 AM, joe wrote: > Yep, indeed it is!
