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.
line upwards Spectrogram
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 (EXE, 294 KB) on my webpage. Thank you Mr. Horne!

upwards Azimuth by Tony Field, VE6YP
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.
upwards AZMap by Paul Burton, AA6Z
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.
upwards Free Azimuthal Maps by Tom Epperly, NS6T
Free Azimuthal Maps Who want to use Beam maps without installing a program, who con use the Free Azimuthal Maps by 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.
upwards Mini Ring Core Calculator by Wilfried Burmeister (SK), DL5SWB and Klaus Warsow, DG0KW
Mini Ring Core Calculator The freeware program Mini Ring Core Calculator in the now avaiable version 1.3.1 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.
upwards NCDXF/IARU International Beacon Network
NCDXF/IARU International Beacon Network 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 4 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.
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.
upwards VOACAP
VOACAP Online Coverage Maps 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.
VOACAP Online Point-to-Point Predictions At the Online Coverage Maps, you can receive predigtions for the whole world. The Online Point-to-Point Predictions is usuable, if the propagation for a point-to-point connection should be estimated. The Pro­pa­ga­tion Plan­ner enables the prediction of the propagation conditions to each of 21 areas worldwide on the short and the long path. On the DX Charts you will see when the upcoming large DXpeditions should be reachable.
upwards Kp Index by German Research Centre for Geosciences
Kp-Index ©: GFZ 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 at the current Kp index graphically prepared on its .
nach oben Space Weather Conditions by Space Weather Prediction Center
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", i.e. 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).
line upwards Solar-Terrestrical Data by Paul L. Herrmann, N0NBH
Solar-Terrestrical Data © N0NBH 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 website, as it is done here.
upwards HamQTH by Petr Hlozek, OK2CQR

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.
CSS Validation Service 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 http://) 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.
