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.

Jim is slightly optimistic. The "nominal" audio frequency for the JT65A software is 1270.5 Hz and the "window" is +/- 1000 Hz (see: pg 35, JT65-hf-setup.pdf distributed with the JT65HF package by W6CQZ). In practice most transceivers do not work very well in the bottom 200 Hz or so of the "window" due to IF filter roll-off leaving room for 8 to 10 signals maximum. 73, ...

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!
