www.qrp4fun.de Software for ham radio operators

You do not only want to use your computer for plays? Then I would like to tell you a few programs, with which you can use him also for the amateur radio. In addition, I would like to point you to the calculations I have made.
 
Spectrogram Richard Horne to the top
 
Spectrogram Spectrogram The program represents the AF spectrum. It needs only a sound card. I use it very gladly for measuring on IF/AF filter. Only a source of noise to the receiver input, the AF output to the sound card and already I can see, how the filter operates.
Mr. Richard Horne, the creator of this program, gave me in November 2005 the permission to put the last freeware version 5.1.7 on my webpage. Thank you Mr. Horne!
 
Spectrum Lab Wolfgang Büscher, DL4YHF to the top
 
Spectrum Lab Spectrum Lab The program Spectrum Lab represents the AF spectrum as waterfall diagramm and/or "fidgety" line. It needs only a sound card. The features of this program are manifoldly, but with experiments you can handle it without reading the help file.
 
sPlan Abacom Ingenieurgesellschaft to the top
 
sPlan sPlan With the program sPlan 8.0 by Abacom you can fast design schematic circuit diagrams on your Windows PC. A extensive and easy to extensible component library will help you thereby. Within minutes you will understand the handling of the program.

Sprint-Layout Abacom Ingenieurgesellschaft to the top
 
Sprint-Layout Sprint-Layout With the program Sprint-Layout 6.0 by Abacom you can easily and fast design single-sided and double-sided printed circuit boards on your Windows PC. The handling of the program is learnable within minutes.
There is a demo version. Although it does not allow printing and saving, all other functions can be used.
 
Azimuth Tony Field, VE6YP to the top
 
Azimuth The program Azimuth represents the world (or a window of it) in azimuth or classic projection. A simple way, to print your own Beam maps for each point of the earth. An alternative with more features is AZMap.
 
AZMap Paul Burton, AA6Z to the top
 
AZMap The program AZMap represents the world in azimuth projection. A simple way, to print your own Beam maps for each point of the earth. It's possible to display among other things also the aurora zones and the night side of the earth, like to see in the screenshot. An alternative with less features is Azimuth.
 
Free Azimuthal Maps Tom Epperly, NS6T to the top
 
Free Azimuthal Maps Who want to use Beam maps without installing a program, who con use the Free Azimuthal Maps, Tom Epperly, NS6T. After you put in your own location and the wanted size a PDF file will be created. This file you can print.
 
Mini Ring Core Calculator Wilfried Burmeister, DL5SWB; Klaus Warsow, DG0KW to the top
 
Mini Ring Core Calculator The freeware program Mini Ring Core Calculator in the now available version 1.3.3 makes it easy to calculate the inductance, the number of turns, the resistance, the necessary wire length and other technical features of coils. Withal both different core types/sizes and the construction of air coiles are supported. The operation of the program is alternatively possible in English, German, French and Italien. The program is available here.
 
NCDXF/IARU International Beacon Network to the top
 
Northern California DX Foundation NCDXF The NCDXF/IARU International Beacon Network with its beacons is a good aid to estimate the propagation conditions. The project covers 18 beacons, which are developed in all parts of the earth. The beacons send cyclically all 3 minutes. The callsign is always send with 100 W. Then four long dashes of 1 seconds follow, with which the output is lowered from 100 W first to 10 W then to 1 W and at the end to 0.1 W. Than the next beacon follows.
Beacon schedule If I switch on my station, I observe only once these beacons. Because its transmit also with 10 and 1 W I can take a good judgement over the conditions and whether staying on the bands is meaningful or not. The time, when which beacon sends, indicates my beacon schedule. Thus I can assign still callsign signals, which I heard not completely.
 
VOACAP NTIA/ITS to the top
 
VOACAP - MUF Map The online-tool VOACAP (Voice of America Coverage Analysis Program) is usuable for propagation predictions for shortwave connections in many versions. All parts are qualified for the frequency area from 3 to 30 MHz. The "MUF Map" is the prediction of the maximum usable frequency.
VOACAP - REL VOACAP - SDBW "REL Map" is the prediction of the QSO reliability from any point in the world on a freely selectable band with a predetermined antenna and power. The "SDBW Map" is the prediction of the signal power level at the receiver. In addition, there are various other predictions. Give it a try!
 
Kp Index German Research Centre for Geosciences to the top
 
Kp-Index © GFZ (CC BY 4.0) The Kp index was developed to represent solar particle radiation from the last 3 hours by its magnetic effect. The symbolic representation takes place in numbers from 0 (quiet) to 9 (extreme storm). The Kp index is determined by a standardized procedure from the data of 13 worldwide observatories. The German Research Centre for Geosciences (GFZ) provides the current Kp index of the last 3 days graphically prepared. In addition, the data are avaible in the archive back up to 1932 - also graphically processed.
 
Space Weather Conditions Space Weather Prediction Center to the top
 
Space Weather Prediction Center The Space Weather Prediction Center belongs to the National Oceanic and Athmospheric Administration (NOAA), among others. It deals with the "space weather", for example the electrically charged particles that are continuously emitted by our sun at a speed of more than 300 km/s. This particle stream is also known as the solar wind. If this wind hits the Earth, it has different effects on magnetosphere, ionosphere and thermosphere. On the webpage of the Space Weather Prediction Center the strength of the solar wind is indicated and when a geomagnetic storm is to be expected. In addition, a small video shows when it will come to Northern Lights (Aurora borealis).
 
Solar-Terrestrical Data Paul L. Herrmann, N0NBH to the top
 
The activity of the sun influences the propagation conditions on Earth. Compact representations of measured and calculated values provides by Paul L. Herrmann, N0NBH, on his webpage.
He also provides explanations on certain values on the amateur radio bands. The presented illustrations can be integrated into your own webpage, as it is done here.

HamQTH Petr Hlozek, OK2CQR to the top
 
HamQTH If you are looking for an address of an international ham radio station, so HamQTH offers information, which are visible completely also without a registration.
The freely available call sign lists from each country are basis for the data. Each ham radio operator determines, which information are presented. It's possible to present only the name and the QTH, but also addresses for snailmail, the webpage or email and so on. Who want to be deleted from the directory sends only an email to the owner.
 
QRZ.COM Fred Lloyd, AA7BQ to the top
 
QRZ.COM If you look for the address of an international ham radio station, then QRZ.COM offers a comprehensive database with information. The information should be correctly, because they are entered there by each ham radio amateur themself and also hopefully kept up to date. There is a disadvantage however: In order to be able to see all information, you must have registered yourself and logged in before. But you can copy the address afterwards also from the webpage in order to paste it for example into the write program for labels.
 
Hamcall Buckmaster International to the top
 
Hamcall If you look for the address of an international ham radio station, then also Hamcall offers a comprehensive data base with information. The information should be correctly, because also they are entered there by each ham radio amateur themself and also hopefully kept up to date. The address is immediately visible. If you want do see the email address, you have registered yourself before and logged in. The address is copyable only as picture of the webpage. But each write program for labels permits also to insert pictures, so you do not have to type the address.
 
SelfHTML Stefan Münz to the top
 
SelfHTML-Wiki You want to design your own webpages? There are an extensive and free documentation named SelfHTML about the design of webpages. Stefan Münz of TeamOne created it from 1995. The documentation is already online available as Version 8.0 and for offline use as Version 8.1.2. It is/was also available as book.
HTML5 handbook Later, with the support of others users, it became the SelfHTML-Wiki. Without that documentation my webpages would not look like it does now. The best source of knowledge I know!
But the internet is evolving. In the meantime, there is the HTML5 handbook created by Stefan Münz and Clemens Gull. It is available as E-Book (PDF) by Franzis-Verlag (ISBN 978-3-645-20345-6). The full contents of this book can also be viewed online here.
 
ftp-uploader Gregor Schommer Systemberatung to the top
 
ftp-uploader After creating webpages, you certainly want to publish them. There are many suitable FTP programs that allow the project designed on your own computer to be transferred on a rented web space. However, I have only found only a single program that automatically detects new or modified webpages and only uploads these pages. All other programs must be told which files to upload. The program I use is the ftp-uploader. In addition, the program can be operated in a time-controlled manner and can be used, for example, to upload periodic newly generated files.
ftp-uploader If you're a privat use and only want to create a relatively small project with fewer than 500 items, you can use it as a freeware version for free. Otherwise, it costs one time 19.95 €. Then, however, an infinite number of folder/projects with as many files as they like are transferable.
Addendum: My provider, Telekom, switched all FTP access to SFTP from the beginning of April 2019. As a result, the ftp-uploader could no longer access my web space. But there is a guide to configure the additional program Bitvise Tunneliers. After that, the ftp-uploader can be used by telecom users again.
Addendum 2: Since October 2020, Strato customers must first activate their FTP access - SFTP is used on a low standard. But there is also a guide for this.
 
MailWasher Free Mailwasher to the top
MailWasher Pro Firetrust
 
Mailwasher Spam is every bit of unwelcome and circulars in your post box. Fortunately there are ways to decrease or eliminate the amount of spam you receive in your daily e-mail. MailWasher Free by Mailwasher is the free available version. Although this version is no longer continued to develop, it is fully usable for the spam defense. However the free version can supervise only one email account.
Firetrust The follower MailWasher Pro from Firetrust develops constantly and possesses more possibilities than the free version. It is 30 days free for use, but the money for registration is profitable.
 
AntiVir Avira to the top
 
AntiVir In the meantime there are a lot of computer virus - and each day there are more. That's why it is importent, to protect oneself effective against digital attacks. An easy method for it is the AntiVir Personal Edition by Avira, which is free for personal use.
 
Firefox Mozilla Foundation to the top
 
Firefox If you look for a web browser, which is safe and nevertheless fast, then regard once the free Firefox. It comes from the house Mozilla and is available for Windows, Macintosh and Linux computers. The standard design can be extended by various add-ons. In addition different language modules are offered.
 
Thunderbird Mozilla Foundation to the top
 
Thunderbird Before the next thunderstorm draws up while handling your past e-mail program, you should test the free Thunderbird. It comes from the house Mozilla and is available for computers with the operating systems Windows, Macintosh and Linux. It administers several accounts independently and makes the problem-free import of messages from the program used so far. In addition it is available with different language modules.
 
form.taxi Reinhard Söllradl - wrkt*biz to the top
 
SmtpJS Since August 2022 I use the free service by form.taxi for sending the data from my guestbook via e-mail to me. These service can be used free of charge in case of low volumes. As a result I must integrate no PHP or Perl on my webpage and the visitor can still send me a message. You can configure the form according to your needs, because the formular remains on your own webpage.
 
Validators W3 Consortium to the top
 
W3 Consortium Especially one who designed his webpages without any automats will also want to know after completed work, whether the provided HTML text is also error free. Because if the rules set up by the W3 consortium are only kept, the pages are indicated in such a way by the different browsers, how it also intended the author. Some browsers tolerate also small errors, but one should designed webpages without errors. You can use for HTML files the Makeup Validator Service.
CSS3 HTML5 The procedure to check the contingently used CSS files is identically. This time you use entirely the CSS Validation Service. The checks functions as follows: Go to the respective Validator, enter the complete address (with https://) of the webpage and cklick "Check". If all is correct, this indicated by a green symbol. Otherwise the symbol is red, the number of the errors/warnings is displayed and the affected positions will be displayed.
In addition, the W3 Consortium provides the Link Checker, which allows you to check the link of a webpage.
