MISCELLANEOUS SIGNALS:






What is a driftnet beacon?
A driftnet beacon is a battery-powered radio transmitter installed inside a marine buoy. This "radio buoy" / "fishing buoy" / "fishery buoy" [photos] is tied to the end of an ocean drift net, or occasionally, a longline (see this news article). The signal allows fishermen to perform RDF (radio direction finding) techniques to determine the exact location of the net after it's been deployed a while. The high popularity of these driftnet beacons is undoubtedly due to their low cost--they are a "poor man's alternative" to the remote control radio buoys, GPS-enabled buoys, and satellite buoys. Driftnets longer than 1.5 miles were outlawed worldwide in the early 1990s.

What does a 26 MHz driftnet beacon sound like?
Typically, after about 10 seconds of a single tone (to allow RDF), a Morse code identifier or "callsign" is transmitted once before the beacon goes quiet for a moment (usually around 100 seconds). The callsign is thought to be unique to each driftnet, and it's assumed that the callsigns are chosen by a single equipment supplier since the majority adhere to a 3-letter standard on 26 MHz, and a 2-letter standard (with poor dot/dash ratio) on 28 MHz. Using CW-R mode to monitor them, you will hear the characteristic drop in pitch (presumably from the battery dropping in voltage). Hear them for yourself: Any beacon listed in the above charts as a link is an MP3 sound file that can be downloaded to your computer.

Why are some callsigns found on multiple frequencies?
Perhaps the longest driftnets have more than one radio buoy attached, and a new frequency is needed for each buoy so that the fisherman is not burdened with listening to all signals crammed together on one frequency. Or maybe each new frequency represents a different driftnet owned by the same owner, although two signals of the same callsign have been heard simultaneously on the same frequency (one example is NAB). The frequency 26.500 is discouraged for use with driftnet beacons as it is the emergency frequency (AM mode) in New Zealand's HF Citizens Band (source).

What are the chances that these are really signals from driftnets and longlines?
One of them actually has a callsign of NET. The mathematical probability that these three characters were chosen at random is
     1     
46,656
and one has a callsign of FISH on 26.555 MHz (and 26.830 MHz as reported by a European listener whose loggings are here). The chances of that callsign being randomly chosen are worse than one in a million:

1,679,616

Where are these driftnet beacons located?
The thinking is that most of the ones I hear are in the Pacific offshore regions of Central and South America. Evidence that supports this theory: About one out of every 4 people in Chile is associated with the fishing business, and "18-20 percent of the world fish supply comes from the areas fed by the Humboldt Current." Many are thought to be in the Atlantic offshore regions of Brazil through Argentina. The best way to determine location is to simultaneously listen to signals of known location on nearby frequencies (such as ham radio beacons found on 28.160 - 28.300 MHz). It is important to do this under weak signal conditions because otherwise, the bands could be open to multiple locations at the same time, and location predictions would be difficult (often the short F2 hop and long TEP hop signals come in at the same time). There are three ways to get weak conditions: 1) listen when the Solar Flux Index is less than about 90, 2) monitor outside of the strong F2 seasons of March/April and October/November, or 3) monitor when the proton level is high after a solar flare. Remember that any ghost net (drift net that has been abandoned in the ocean) is not likely to be in the same location year after year because of the influence of ocean currents. To get some idea of which nations are most likely to have an active fishing industry, look at this chart of fishing industry by country. It shows that Peru leads the way, followed by Chile, Argentina, Brazil, Venezuela, Ecuador, and Panama. Also, remember that one of the callsigns contains the letter — which is part of the Spanish alphabet, but not the Portuguese or English alphabets.

Are these signals coming from actively maintained nets and lines or from "ghost" nets and lines?
Most are coming from actively maintained driftnets and longlines. The transmitters are battery-powered devices, so if there is nobody replacing the batteries, the transmitters would eventually have to lose power completely, although some designs may include solar panels in order to try keeping the batteries operational longer. The fact that these signals are present year after year suggests that someone is replacing batteries. For example, beacon "MMI" was logged by another enthusiast in 2002 on 10m and is still transmitting October 2016 on 26 MHz. Also, some callsigns are found on multiple frequencies in the same moment of any given day, suggesting either that very long driftnets/longlines are being used (with one radio buoy attached every few hundred meters), or that multiple nets are in use by the same owner at the same time in the same "skip touchdown zone."

What propagation mode is allowing these signals to be heard in NY State?
The furthest signals are coming in via F2 propagation, including "afternoon TEP" (Trans-equatorial Propagation). Signals that travel via TEP tend to start and finish at roughly equal distances from the magnetic equator (south of the equator), with up to 15 degrees of tilt off a straight north-south path. For example, in April 2012, I had the rare occasion to work 6m TEP to northeastern Argentina on paths that were as far as 14.2 degrees east of south. The west coast of South America is at the same general longitude as NY State (about 75 degrees west). F2 is possible to northern South America, and same-hemisphere F2 is possible to distant parts of the Gulf of Mexico, with path lengths of 1500-2000 miles. Sporadic-E signals are possible from the northern Gulf of Mexico, especially from 0900-1400 local time, and especially outside of the conventional F2 seasons of March/April and October/November, but no sporadic-E signals have been confirmed yet. The unique thing about monitoring these signals is that the best conditions occur when the propagation is NOT favoring land masses. When that's the case, you get not only enhanced conditions to maritime areas, but also attenuation from the high-power land-based signals that interfere.

Best time to listen:
During your local daylight hours. Daylight hours are the only time F2 is available to facilitate hearing these signals (unless you live in the tropics where sometimes F2 conditions persist beyond local sundown). In some years, morning and evening are best, probably due to the grayline DX advantage. In other years, the middle of the day works best, with a slight weakening almost always noted during the hour of 11:30 AM - 12:30 PM local time when the absorbent D-layer is most active directly beneath the sun. I am noticing in 2013 that when the Solar Flux Index is below 100, the signals don't start appearing in the morning until the local 0800 hour. But when the flux gets higher, the signals begin showing up in the local 0700 hour. The best time of year is March/April, and October/November. The reception of these signals during the day shows that driftnets are not being deployed exclusively overnight as some have claimed. Of course, if they are ghost nets, then the transmitters will operate continuously until the batteries are dead.

Why log them?
Once their locations are known (and if the location is always the same), the hope is that these transmissions can be used as daily propagation indicators, serving the same purpose as licensed beacon transmitters. Since they are being heard via F2, they could also provide clues to the overall condition of the F2 layer to allow such things as studying each solar cycle or confirming a proton event after a solar flare. Southeastern US stations reported unusually high amounts of TEP on 6m in early 2012 (which also made it into the northeastern US). The TEP returned to the northern US on 05-September-2012, which was very likely a clue that the F2 layer is increasing in robustness the way it did just before the first peak of Cycle 23. Finally, on 09 November 2013, I worked my first 6m F2 since Cycle 23, and copied Colombian beacon HK6FRC/b at S3 using only my Moxon rectangle antenna while operating away from home. In general, the challenge will be to use all the driftnet information to become more familiar with the behavior of the F2 layer of the ionosphere (which could lead to the discovery of new patterns that occur at a certain point in a day, year, or solar cycle). Furthermore, if any of these signals represents a ghost net, then maybe volunteers can use RDF equipment to track down and remove the nets. If these signals do suggest active illegal fishing methods (as is assumed because of the use of illegal frequencies), then perhaps someday the information will help law enforcement officials catch the offenders. More direction finders can be seen here.

Some of the following observations suggest that these Australian-heard driftnet beacons are a different group at a different location than the ones being heard in North America. But they are likely located north / south of the listeners who reported them, which is the same phenomenon being noticed by listeners in North America:

1) They follow the same sending pattern as the lower HF driftnet beacons (callsign sent 3 times, then silence for approximately 4 minutes). This suggests that the same equipment supplier is producing the electronics for both areas of spectrum (not the case for North American-heard signals).

2) They do not have a bending pitch (better Voltage Controlled Oscillator used in construction? crystal versus synthesized frequency generation? compensation circuit for battery voltage sag?). Most signals heard in North America *do* have bending pitch, except for the signals that are thought to be "status codes" (which are briefly transmitted on the air to confirm a particular status of the unit, such as BA for battery, or PW for power).

3) The bearing for 5ABH and IR2 is being reported as about 180 degrees from Guam on short path, and about 0 degrees from southeastern Australia on short path, making the most likely location the waters 400 km / 250 miles south of Papua, New Guinea.

4) They do not strictly follow the 5 KHz spacing like the units heard in North America.

5) The majority are 4-character callsigns versus the majority being 3-character callsigns for units heard in North America in the same frequency range.

6) Australian listeners report the same phenomenon as North American listeners: Some signals have been heard on the same frequency at the same bearing for years without battery failure. This suggests that there may be photovoltaic cells or wave-action generators charging the batteries. Perhaps these particular callsigns represent ghost nets or separated buoys that got caught in a whirlpool, got drawn into the vortex of an ocean gyre, or washed ashore and therefore don't change location anymore. Perhaps when a buoy becomes separated, the portion of the net or longline previously being held up is now dropping very low and getting snagged more easily on a jagged ocean floor, meaning that any remaining radio buoys on the net are now fixed in location.
