HAM radio searching and pouncing fisherman and hunter ?

 This article is for amateur radio operators but can be interesting for SWL. I translate an article in French.

https://arml.r-e-f.org/pdf/les_concours_radio.pdf

The Fisherman and Hunter Technique.

English-speaking countries say: "Running" & "Searching and Pouncing," which I've translated as fisherman and hunter.


There are two ways to conduct a contest:


• We scan the frequencies, listen, and answer the "callers" (we'll call ourselves hunters).


• We make repetitive calls, and whoever wants to can answer (we'll call ourselves fishermen).


Obviously, during a contest, you can alternate between these two techniques.


The Hunters:



Hunters scan the band looking for a contact. You have to scan kHz by kHz and pay close attention to the received signals.

When you come across someone making calls (a fisherman), wait your turn and try to understand their answering strategy. Do they answer the first callers or the last?


While you wait your turn, be sure to note down the call sign of the fisherman and their control group. You will need these to perform a coherence test when it's your turn.

If you are unable to make the QSO, no problem, memorize the frequency and try again later when operating conditions are better.



Fishermen



Fishermen have a simple technique. They choose a frequency,

ask if it's free (standard courtesy applies), and repeatedly call out "CQ Contest" for

long minutes (30, 40, or 60 minutes). Every incoming QSO is welcome. If you're a fisherman, it's up to you to be quick enough to keep the other calling stations waiting.

When you're a fisherman, don't forget to QRZ at the end of the contact to say

"next," and every two or three QSOs, give your call sign. This will allow the waiting stations to note it down.

Do not exceed a 3- to 5-second pause between calls. Otherwise,

you risk not being heard by a caller scanning the

band. Or worse, if the frequency is good, intruders might try

to take it, either by calling on the same frequency (which isn't

very polite) or by calling 1 or 2 kHz off your frequency, which isn't any more

polite. You have only one choice: choose another frequency, or stay on

this one, indicating that it is already in use and that you are in a contest. If

you are using Morse code, use PSE QSY. In principle, things

sort themselves out. If you have a "strong and clear" signal, you

can try your luck. Be aware that if you ultimately have to change

frequencies, the ends of the band are quieter (less

congested).

Whatever the situation, there is one thing you must never forget:

…remain polite. Try to find a compromise between contestants and non-contestants; ultimately, the bands belong to everyone. Also, keep in mind that

even as a fisherman, you sometimes have to move… this will help you

put things in perspective.


The “hunter” or “fisherman” dilemma

To be a fisherman, you need a certain amount of experience.


The choice between hunting and fishing can be made as follows:


• If you have a powerful station (power, antenna, etc.) with clear and perfectly intelligible audio, don't hesitate, go fishing for QSOs; it's a good strategy.


• If, on the other hand, you have a low or medium power station, or

you don't dare call because you don't know what the response will be, let yourself be fished. Even if your signal is weak, you can

be a multiplier. For the "fisherman," you're already a QSO anyway, maybe even the one that will win him the match, so be sure he'll do everything he can to copy you.


Keep in mind that in a contest, there are more hunters than fishermen.


That's partly why fishing pays off.

Use this fact and make your calls.

The best SWL active antenna 10 meter to 160 meter HAM bands


This antenna is use by the famous WEB SDR Maasbree in the Netherlands


In a world where increasing noise and QRM levels in residential areas are worse than ever, radio amateurs have to look for solutions. So, do, what the professionals do, and set up antennas on remote rural areas, and use the internet to distribute the received signals to the amateurs. Use WebSDR techniques.

  • Offering an alternative for radio amateurs with high local man-made noise levels
  • Supporting making QSO’s (short latency <0.5sec)
  • Supporting ham bands only and including CW segments
  • 24/7 available, reliable and predictable
  • Antenna radiation pattern matching transmitting antennas common on residential locations
  • Not intended to be a shortwave listening station or to provide the best possible reception

 

Why the choice for WebSDR?

  • it offers a 400msec well controlled low latency
  • supports a large number of users

Low consistent latency <500msec is essential for making QSO’s using a WebSDR!

 

This WebSDR uses a single broadband antenna for the 80m/60m/40m/30m/20m HAM radio bands. It is intended to give radio amateurs the possibility to receive a good signal on these band, in terms of QRM/Noise. It has not the intention to be the best receiving facility. Amateurs have to use their own transmitting antenna at their residential locations. It makes no sense receiving a lot of stations that are not able to hear you. So transmitting and receiving should be in balance.

A quick overview of the set up is given. The active small broadband receiving antenna is a 1.69 m2 small loop with a broadband amplifier. From there we use a 100m coax cable to the shack. In the shack we have a 5 and a 4 band passive filter which is feeding the receivers for the 9 bands. These receivers are connected to two computer. On the computers we run Debian, with WebSDR software of Pieter-Tjerk, PA3FWM, and specific intermediate software for the SDRplay receivers. Bas, ON5HB, helped us with the intermediate software (TNX Bas). More information about the WebSDR project of Pieter-Tjerk can be found on http://www.websdr.org.

Pieter-Tjerk (PA3FWM) is the developer of this WebSDR   concept.

Initial development was for the bands 80m, 60m, 40, 30m and 20m. Later in 2020 we also started to work on a 2m websdr, which came to life end of 2020. Early June 2021 we splitted the 2m band in a lower band (horizontal Big Wheel) and a upper band (vertical Diamond). Most of the work for the 2m band was copy and past, but a separate chapter is written to discuss specific 2m issues. The 2m websdr runs on a PI4. April 2022 we added the higher HF amateur bands (17,15,12,10m).

Antenna for the HF bands

A small broadband active loop antenna: Active broadband loop antenna

Broadband loop amplifier (update March 2022 of 2018 and of 2003 design)

 

 

The broadband loop amplifier design requirements

  • Bandwidth starting from 1.8MHz or lower and up to 30MHz
  • Noise contribution lower than the rural ambient noise level
  • Best balancing and decoupling from the feeding coaxial cable (minimizing coupled man-made noise and for measurement applications)
  • Very good large signal behavior (IM products <= noise level of the amplifier)
  • Output level comparable to the half wave dipole
  • Controlled gain (especially if using loops in matched pairs and for measurement applications)
  • Overload protected (your own transmit signal e.g.)
  • Receiver maximum input level limited to about 13dBm
  • Filtering potentially overloading local out of band (VHF) signals
  • Using regular components, not too complex circuit, no SMD’s (junk box)
  • Low visibility of the loop for neighbors

Of course the result will be a compromise, on all aspects good enough.

(see for the principle of the amplification: Broadband amplification)

Design and specification bandwidth: 1MHz-30MHz

Note: balancing and visibility both are very relevant on a residential location. Especially balancing is most relevant because of the high man-made noise levels on residential locations.

 


The null of the loop is pointing east/west. The null is orthogonal to the surface of the loop.
Gain in the WebSDR is set for an equivalent antenna factor AF=0.35 on all bands.
PCB design by PA3CSG.
The PCB is available through the Maasbree WebSDR website.

Why not a old transceiver from Japan to listen shortwave

 YAESU, ICOM, KENWOOD and other Japanese brands have made a lot of TX RX for amateur radio operators. Last 35 years. In North America or Europe, but also in Asia or South America, it is not hard to find one in good shape to listen to medium wave and shortwave. These brands don't make only receivers in 2025 and the price of a transceiver is a minimum of 1000 euros or US dollars.  French makes a website with prices of secondhand TX.

https://web.archive.org/web/20201216020146/https://radioamateur.org/argus/

Prices are in euros, and one euro is 1.18 US dollar.

Price start at 170 euros

They have now a website for secondhand amateur radio equipment 

https://radioamateur.org/

Some shops sell secondhand radios.

On RIGPIX you can see all the TX made by Japan

21 and 22 February 2026 you can listen all the the French departments and French overseas territories

Rules of the contest French HF Championship "Coupe du REF SSB"

https://concours.r-e-f.org/reglements/actuels/reg_cdfhfdx_en_20250315.pdf

F stations send RST+Dept number (or Prefix for overseas French stations) Ex for F6XXX: RS 59 dept; 75 So it's simple to know who the department number is.

Bands 80, 40, 20, 15, 10m

What is a French département?



https://www.axl.cefan.ulaval.ca/europe/france_departements.htm

A department is a territorial division that can be either an administrative district or the territory where the departmental authority operates. The departmental capital is generally the seat of the prefecture and the local government services, but some exceptions exist.

There are 101 departments as administrative districts and 94 departments as territorial authorities



The other territories of the French Republic are not departments. They nevertheless have a similar code.

Five overseas collectivities:

975: Saint-Pierre-et-Miquelon, a department from 1976 to 1985, has not been part of the European Union since 1985 (OCT);

977: Saint-Barthélemy, a single collectivity, formerly attached to Guadeloupe, has not been part of the European Union since 2012 (OCT);

978: Saint-Martin, a single collectivity, formerly attached to Guadeloupe, is part of the European Union (OR);

986: Wallis and Futuna, a single collectivity, has never been part of the European Union (OCT);

987: French Polynesia, also designated an overseas country since 2004, has never been part of the European Union (OCTs).

An overseas country with a sui generis status:

988: New Caledonia, has never been part of the European Union (OCTs).

An overseas territory with a special status:

984: French Southern and Antarctic Lands, without a permanent population, composed of five districts: the Crozet Archipelago; the Kerguelen Archipelago; Saint-Paul and Amsterdam Islands; Adélie Land; and the Scattered Islands in the Indian Ocean.

A unique collectivity, falling under the State's private domain:

989: Clipperton Island, formerly part of French Polynesia, without a permanent population.

Seven overseas collectivities of the French Republic share their territory with departmental constituencies:

Three collectivities with special status (CSP):

69M: Lyon metropolitan area with the Rhône constituency (69);

75C: City of Paris with the Paris constituency (75).

The collectivity of Corsica with the constituencies of Corse-du-Sud (2A) and Haute-Corse (2B).
Three single territorial collectivities (CTU) located overseas:

972R: Martinique (972R) with the Martinique constituency (972);

973R: French Guiana (973R) with the French Guiana constituency (973);

976R: Mayotte (976R) with the Mayotte constituency (974);

Example: Île-de-France region


Paris is the French department number 75



In this region there are 12 271 794 inhabitants

I remember in the 90s when i was younger, I listened to all the French departments on the weekend of this contest

Beware of excess: how many cups of coffee does it take to consume too much caffeine?
According to the European Food Safety Authority (EFSA), a healthy adult should not exceed 400 mg of caffeine per day, the equivalent of four 200 mL cups per day. Consuming too much coffee can have harmful effects on your health.

1. It's a proven medical fact that we should sleep in multiples of 90 minutes. Most sleep 90 mins on early Sunday morning, and some on Saturday morning too. In general, it seems like a good idea to get 3 hours in before the contest starts, which is easy in Europe, but difficult in West USA. Varied feelings about whether to get a'lie in' on the Friday morning, but certainly not good to have a very late night on Thursday. 'Adrenelin' seems to be a big factor for some in keeping you going through the weekend. For others, the opposite is true - relaxed and laid-back gets them through. Whether you're wired or tired, it makes little difference to the final result. It's the ability to sustain concentration that matters.

2. Drink in moderation, but regularly. Drink to quench your thirst. Do not drink caffeinated beverages. Caffeine will lower the blood sugar level thereby affecting the ability to concentrate. Coke, tea and coffee contain caffeine. Milk will make talking difficult - radio and TV news readers avoid milk. Unsweetened fruit juice, a little often, is good. It is far more difficult to wake up if you have managed to get to sleep with a high caffeine level.

3. When to eat? Stick to eating at regular intervals. Every 6 hours with a small snack at 3hr intervals is good. Normal eating times are also good. It's what your body expects.

4. What to eat? The objective is to maintain a steady blood-glucose level of around 4-5 mmol throughout the weekend, with a slightly higher than normal intake of protein. In normal healthy individuals, high blood-glucose levels lead to poor concentration and drowsiness whilst low blood-glucose levels lead to iritability, short temper and loss of aptitude. 4-5 mmol, a moderately low level, will be achieved by avoiding anything containing simple carbohydrates like sugar or bleached pure white flour. So, good is wholemeal bread, bad is plain white bread. Good is potato skins, bad is creamed potato. Good is natural fruit juices, bad is sports drinks. Good is fruit, bad is sweets/candy. While sports drinks will give the body a big hit of energy, this hit is followed by a very deep low in blood-glucose levels. Complex carbohydrates (vegetables, fruits and grains) are good, in that they take a long time to digest, help maintain a stable blood-glucose level and help avoid surges.

So what should we eat and drink?

sandwiches of wholemeal bread, with meat or cheese
fruit/grain/granola bars (but watch out for high sugar content)
pure orange juice
water
nuts
apples
banana

5. How much to eat? In general, it is best to eat less food than you would normally.

6. Avoid smoking.

7. Keep fit. This is really quite important. If you are fit your body will react less badly to poor sleep patterns.

8. Avoid alcohol and sexy ladies !!! I joke

9. Avoid working on 'stuff' right up to the wire. Prepare well for the contest and 'know' what you have. There is a hidden side to knowing that you are well prepared. This will help you relax prior to and during the event, which is one of the keys to making it through the full 48 hours. It feels good to feel loud, and believe that your signal is getting through - 'I know what I'm doing'. Learn from the previous year. Immediately after a major contest write down what was wrong, what went wrong, what was good, and what was bad. That way, next year you will be a little more prepared, and a little more relaxed.

10. Smile when you talk. Sound happy. Even if you feel like death, don't let the other guy know it! People like to call happy people. Not a lot of good on CW, of course.

Other points worth noting...

Vitimin B can help you feel less tired over a period of time, and may be beneficial. I would not take this as a recommendation to take vitamins though - see your doctor first!

Ask your doctor before the if you have health problems such as diabetes, high blood pressure, etc.



Be careful if you are a real OM (old man).
