Preliminary considerations

First of all, a few important points:

  • it leads to the need radio monitoring in order to get a clear picture of your area. This activity becomes vital. If you are not doing anything in terms of communications, then at least have monitoring equipment;
  • your communication equipment must be autonomous, work without power;
  • energy to power the equipment;
  • it is necessary to accomplish the tasks;
  • Many scenarios will require the ability to work from field conditions. Your equipment must be portable or at least easily transportable;
  • workshops on repair of electronics will consider if you consider long-term energy autonomy scenarios. At best, you can turn to a handicraft or self-taught with a modest choice of spare parts and diagnostic devices. Your equipment must be maintainable in these conditions;
  • You may want to apply certain methods. communication protection (COMSEC). Depending on the type of situation and the severity of the radio channel, it should be noted.

Please note that your communication points are not subject to autonomous conditions.

The most importantly of all, and, unfortunately, the most often overlooked. It gives you the signal to read the signal. This attitude should be changed.

Listening is twice as important as transmitting. Good set radio monitoring equipment to each survivor should be considered as an urgent need. Fortunately, to equip a modest but effective monitoring post You will need very few specific branded equipment.

Independent power sources. Batteries or 12-volt DC. This can seriously affect the equipment lamp in the context of EMP. This is a list of radios.

Monitoring of VHF and CB broadcast stations

Is tactical point of view, especially in relation to emergency communications monitoring. However, tracking channels are even more important for assessing and future trends. If you can, you can touch you. You can use it.

So, the equipment of the first stage for your radio monitoring post probably already at your disposal. It is portable broadcast radio on the VHF and CB (Translator’s note) and on the ultrashort (VHF) are often called the AM band and the FM band, respectively. However, there is no need for a modulator, however, it is not necessary to do so. The VHF is divided into a number of ways to mention the VHF. It is a rule of thumb, that is, the interval of 400-500 MHz. . If possible, both should be connected to quality external antennas for the best reception. Such as electronics and electronics stores. In the case of the aerials . Loop antennas have excellent quality, such as directivity.

The main stations federal channel repeaters, because they are from the sides of the political spectrum. I would like to clarify the problem below in more places. It is up to a hundred kilometers away. Will be closer during the day. Do not bother with cable and satellite TV – the costs are not worth it.

Broadcast news adds one piece. As an example, it was transported by rail. It’s not a problem. monitoring broadcast stations The National Guard from Fort Carson at the National Guard Training Center. From here you can begin to unwind the tangle of details. What is happening around you.

Setting up a modern TV is simple. Turn on and start scanning channels. He will find the stations that are currently broadcasting. This is a list of newsletters that you need. From the radio a little more fuss. It will be the first time that it has been tuned.

One of the best radio receivers for monitoring SV can be found at flea markets, disassembly, etc. If you are looking for a system for short or short distance heating, you have

This is where you can see the radio stations. They can be quite “unformatted”, but this is valuable.

Designed for your design radio monitoring post. It can be very useful to listen to a low-power station.

As of September 11, 2001, 12 different television transmitters were placed on the WTC buildings. The Empire State Building. This is a small public station. When the towers collapsed, all 12 stations stopped broadcasting. I’m acquaintance, who was then distressed in a recent conversation. It was received from the WTC. If you have any additional features, it can be useful to receive a signal from a spare broadcasting site, or from another area.

If you’re a lot of people, they’re not a lot of money. For a beginner, installing a radio channel. The same applies to broadcast range scan, Consider the radio station where the radio station was a radio station. the characteristics of the differences).

Monitoring shortwave broadcast

So far I have a wide audience, accessible to listening with consumer electronics. VHF and CBA, United Kingdom and National Oceanic and Atmospheric Administration. local disasters of natural disasters. This is an important picture. Now we will expand our interests to shortwave broadcasting.

The shortwave bands (from 1.7 to 30 MHz) have the ability to provide connectivity around the world, however, many users emergency radio communication (such as RAS (Note. Interpreter. In amateur radio, which is a real radio emergency service), ARES, Racks, etc.) amateurs on the air.) Amateur radio, amateurs on the air, VHF radio to fail task. Short waves are also used by various broadcast stations around the world. Your broadcasters broadcast. This is important, since it’s not possible, it’s biased. By collecting the data, you can neutralize the distortion and relatively reliably imagine what is happening.

If you want to see what kind of mode is it? It can be either USB or VBP, UBB, or LSB, or NBP, or UBB, SSB “generally” can be used. option.). SSB is a narrowband voice mode on shortwave. SSB also for a variety of digital modes, used by amateur and departmental stations. Many modular mode signals used by shortwave broadcasters.

Since you’re not getting any attention to you, you can’t pay attention to these frequencies. A good receiver covers frequencies from 500 kHz to 30 MHz and above. This includes amateur bands, international illegal stations, and CB.

The illustration shows a wonderful receiver. Icom R-75, which I highly recommend. It is an easy-to-use device for reserve growth opportunities. It accepts AM, SSB, CW, and FM modulations from 30 kHz to 60 MHz. Ike analog architecture (not SDR, software-defined radio). It can be a good idea to buy it for three hundred dollars.

It’s not the case for the VHF, it’s not. Tactical military radio stations of 30-88 MHz, in increments of 25 kHz. When they are not in frequency hopping mode, they usually work with a 150 Hz subton (the standard subton 151.4 is quite compatible). Also, it is important to note that there are radio transmission stations for transmitting radio transmitters above the sibi-shih frequency.

There is no need for more than 1.7 to 30 MHz, and not just within the amateur bands. If you choose to receive a call sign, a radio amateur license, rather than a receiver. Are not satisfied with the models. Icom IC-718 or Yaesu FT-857. It is not so important that it is a practice to practice with the chosen one. However, it’s better to save money and stay on the receiver.

Different ranges of short waves are better. In general, the 1.7-6 MHz waves propagate better at night, 15-30 MHz work well during the day, 6-15 MHz function normally 24 hours a day.

It’s best to start short listening broadcasting stations. They use AM modulation, broadcast at a certain schedule. You can find the following sites:

Shortwave bands are also used to communicate over long distances. This is in contrast to the “broadcasting” stations. When voice mode is used, modulation is applied by USB. It can be found at the link below.

Amateur Radio is another user of shortwave communication, you may be interested in monitoring networks, weather and regional networks. This is an Internet search engine.
