For three years now, Chita has been working with the free ATIS by Phone service. If you call + 7-914-450-7126, you can listen to weather reports. The robot reads, in Russian and English. It works during daylight hours. Chita has a time difference of 6 hours with Moscow.
Meteorological information is taken from the radio at a frequency of 126.4 MHz. And then it is simply transferred to a mobile phone configured to automatically receive a call. There are no restrictions on the duration of the connection. Multichannels, however, also: at one point in time, only one incoming call.
For reference
ATIS (Automatic Terminal Information Service, ATIS) is an automated system that constantly transmits to the radio at the set frequency (usually in the VHF band) information about the meteorological situation in the aerodrome area and the operational information necessary for the aircraft crew to plan the departure and Arrival The abbreviation ATIS in Russia is officially adopted and used in all regulatory documents.
Using ATIS can reduce the load on the dispatcher, making it unnecessary to transmit the same information to each new crew in his area of responsibility.
Information is transmitted at a frequency specific to each aerodrome, which can be clarified by navigation collections. Information is transmitted continuously and cyclically, that is, a message, usually lasting no more than a minute, is repeated again and again. ATIS broadcasts in international airports both in Russian and in English, sometimes at different frequencies.
ATIS reports are regular and special. Regular reports are formed at 00 minutes and 30 minutes every hour. Special reports are formed in case of significant changes in weather conditions (the concept of "significant" implies a transition through certain criteria) or a change in navigation information that affects the operation of flights in the aerodrome area. When generating an ATIS summary, each new message is assigned a letter index. This code (the letter of the Latin alphabet) is transmitted at the beginning and at the end of each message through the phonetic alphabet (for example, A - Alpha, B - Bravo, C - Charlie, etc.). When communicating with the dispatcher, the crew indicates the code of the last ATIS message listened to. Thus, the dispatcher always knows if the pilot has the latest information and, if necessary, asks him to listen to the new message.
The technical implementation of our homemade product is simple. To receive the radio signal, we used a decommissioned R-870M receiver. The Nokia 1616 is watching the GSM network. Between them is a makeshift matching device. Once a day for two hours, the timer starts and recharges the mobile phone’s battery with a standard charger. For three years there were no problems with food. Reservation of energy supply is not provided.
The receiver connects to the phone through galvanic isolation. In order for the mobile phone to know that a headset is connected, and not just headphones, a 5.1 kΩ resistor is provided. A wire with a four-pin plug is taken from a standard headset. The second resistor attenuates the signal from the Loudspeaker output of the receiver. It is better to use the “TELEPHONE” output, but it does not work on our receiver.
We bought the R-870M receiver at some sort of disassembly of the aircraft junk. At first they hesitated a little; there was a choice to take it or a cormorant receiver. We stopped at this - Baklan’s power supply is inconvenient - 28 volts, and ours is powered by a 220 V network.
The antenna is used whip on a magnetic base, forty centimeters long. It takes well even indoors, so just put it on the windowsill. It has been standing there for three years.
If the matching device is assembled correctly, when the plug is connected, the image of the headset appears on the screen. After that, in the properties of the accessory, you need to enable automatic call reception. No settings are required anymore, well, unless the volume of the ringtone is reduced to a minimum.
The matching device is assembled on a piece of foil textolite. Contact tracks are simply cut by a cutter. The transformer is taken from the bulldozer, which was found.
The charger turns on once a day for a couple of hours. This is enough to fully charge the battery. The timer was bought at the store by electricians. It is programmed simply, it works stably.
The second VOLMET by telephone service works on exactly the same elemental base. Information is taken from a different frequency. There are shorter reports, but for several cities. Reads by a man, in two languages. 24 hours a day. The sound quality is not very good - the reports are written, it seems, on magnetic tape. VOLMET phone number + 7-914-804-9361.
The cost of a call is equal to a normal call to a mobile phone of MTS operator.
