Description of the process downloading data and restrictions applicable on QRZ.com

Access to such a large database which is a database of address and other information about the world of amateur stations is limited. Is restricted due to limited bandwidth access and access policy used by webmasters server We must be aware of these limitations.

Database of amateur stations from lookup server contains the following data for amateur stations:

1st Block - Address

1. Station callsign

2. Name the station operator

3 .Adres station in 2 lines

4 .QTH only for a server HAMQTH.COM

5. Name of the country in which the station is

6. E-mail - available only when the mouse moves over the field of e-mail. This is a protection against downloading an address in an automatic way by the programs-robots, and then to send spam advertising of these stations . For a server HAMQTH.COM is possible to obtain this address automatically

7. Photo station operator that loaded the amateur station.

8. Viewed a number of times the station data - so Lookups

2 nd Block - Biography Description stations .

1. Biographical description how loaded the station operator

3. Blok Detail

1.	Callsign station administrating data station - it's the beginning station callsign that this data is introduced and next callsign station when this station has established an account at QRZ.COM .

2.	Date the last update data of the station

3.	Latitude - latitude station

4.	Longitude - longitude Station

5.	Grid Locator Square station in the form of 6 character like JO90hg

6.	U.S. State - State - for the U.S. or Canada

7.	US County - County to the U.S. or Canada

8.	Web Page - a link to a web page if the station has its own page www.pol QSL_via

9.	Field QSL_Info - QSL_Via how to send QSL card. It is the most important field in the data about the station. This field should contain only the following information:

•	Field blank - means and the card has to go through the QSL Bureau

•	Callsign QSL Manager e.g W3IKH eg QSL Manager Golf QSL_Via QSL Manager

•	Word DIRECT

•	Word DIRECT + Callsign QSL Manager eg DIRECT QSL Manager W3IKH

This field is manually entered by user on QRZ.COM , however, and therefore includes many incorrect and inconsistencies in the data. Therefore, this field is not directly suitable for inclusion in the QSL card. Members loggers postulated many times that the loggers programs solve this problem . My program BUREAU_ALL_QRZ_COM program solves this problem by correcting the field QSL_Via described in the chapter. Corrected value of this field is enter to the field QSL_Via Logger32 giving directly to the place it on the QSL card

10. QSL box by Mail? (Traditional)-Contains the word Yes - if you can send QSL card via the traditional - ie direct. If it contains the word No then this route of transmission is not available for some local reason

11. Field to eQSL QSL? may contain the word Yes or No

12 .Field Use LOTW ? may contain the word Yes if the station is registered in LOTW or No if the station does not use LOTW . It should be noted that the field of 10 to 12 may be blank if the user has not chosen these fields

13 . Other Callsigns - other callsign that have a station or have had in the past

14 . Map of the location of the station to the selected position .

Discussed above, if the fields are provided in standard ADIF fields is transfer to the fields currently being conducted QSO. These fields need not even be selected in the window OPERATOR - the main window of data entry. For this to be aware that such fields such as ZIP. Old Call, Web Page, QSL fields by (three boxes) do not fall for to a Logger32, because there are not provided

Collecting data by selecting the station:

•	when you click on the callsign stations on the spot, ie bandmap's or DX Spot Map or in the DX-Spots window when you click on the sign in the window,

•	when you click on the callsign stations on the receiving station in a digital emissions window

•

after the enter manually callsign of the station in the field CALL in a window OPERATOR in the basic data entry window. From this that here there is a rule that after change even one letter or number (deletion or addition) in the window SP9AUV - Lookup - QSL_Via program reset all fields and there are appear blink string Press TAB SPACE ESC or mouse after completing the callsign. You can also press any function key F1 to F12. You can click the mouse on any window Logger32 - not only in the program window. You must to tell program that the callsign is full, otherwise how the program is to know about the end of characters? . For the lazy or not familiar operators introduced possibility, that after a certain period of inactivity since the introduction of the last letters the program itself will begin the process of downloading data from the server. By default this parameter is set to 4000 msec, but you can change it by pressing button CONFIG

•	After the initial introduction of the prefix and selecting it from the drop down menu with the mouse from list of station had already been do previously QSO

Description of the process of downloading data

•	Why do I want to give users the knowledge on the subject. Apparently you are not interested in such knowledge. It turns out that this knowledge will help in taking action when there are problems with downloading this data, or a long wait for the data.

•	As I said above, the fastest is downloading data from QRZ.COM in XML format - it has the highest priority at QRZ.COM. However, this is a paid service.

•

Program BUREAU_ALL_QRZ_COM_FI.exe download data in a text format with very fast downloading of the data. Here are a few observations in the downlink in HTTP protocol what use browser also a mini-browsers build into program . When downloading data over HTTP we need to know the following circumstances:.

•

QRZ.COM server use designated by the webmasters themselves policy priorities. Since for the program is not a problem to determine which browser is using by a computer that gets its web page. I noticed that the prosecution through a browser such as Firefox data from the qrz.com appear much earlier than for those mini-browser built on a ready-made components of the WebBrowser.

•

It should also be aware that such a server as QRZ.COM is quite heavily loaded. In the Internet, each packet has determined time the packet reaches its destination - the so-called Time-to-live . If this time is exceeded packet is simply reset by the router which recognize . Unlike the Internet will to rapidly clogged by circulating a package. It can happen so that our request to provide data for some stations do not reach the goal. It may also happen that only part shall drag the initial data, while the rest of the packets will be cut because of exceeding the time Time-to-live.

•	In this case, as above we should check whether we have the Internet - for example in the DOS window (cmd) issue the command

Ping wp.pl

pinging qrz.com the server does not make sense - because the service is disabled on the server qrz.com
