This provides most all possible variables to calculate the S+N/N ratio of two stations & include, Station Power, Antennae, frequency from 50 MHz to 48 GHz.  Receive noise temperature & cascade noise figure, transmission loss, spill over, feed through, ground temperature & perigee/apogee parameters are provided.  Sun noise respective to Solar Flux, moon noise and ground noise calculations are also provided.  Object size / apertures conversion factor is included.  Y factor measurements of noise sources (commensurate to date) & the ability to vary present values is included to "reverse engineer" your results.  Sun noise is interpolated/extrapolated direct from the Australian Ionospheric Service for real time accuracy. A commercial data base of common yagi antennae is included. Linear to Circular Polarity corrections have been added for cross polarisation situations. Deep Space and Radio Astronomy frequencies are included. A free space calculator is also provided.

Additionally there is a pre amplifier parameter screen to allow you to see all the effects changes will have on your performance.  Coaxial / hard Line cable types & their losses are included.  Termination (temperature variable) to Cold Sky is also provided as well as Transmission Line reflection Loss and Antennae Relay insertion loss.  The reference calculation option provides direct values of losses or gains of any chosen parameter .

An extensive Help file is integral to the package.
 

Based in Prague 2000 this software addresses RF Radiation issues.  It provides for the FCC, Council of  European Union (CEU) & Australian RF Safety Standards as well an adjustable option to suit your own National Standards.  Program covers 1.8 MHz  to 48 GHz for both circular & rectangular aperatures.  Selectable common antenna types are provided as well as variable input.  Height/distance/on axis calculations are provided in a graphic format.  A further graphical display of near & far circular aperatures is included in the package which may help you to convince your authorities that your station is safe for your neighbours. An extensive Help file is integral to the package.
 

Born from the frustration of building feeds with commercially available tube sizes!!! This program allows you to select the size of the inner or outer conductor or required impedance & calculate one of the parameters after selecting any of the other two.  Variable dielectric constant & metric/imperial conversion is included as well as multiple wave length calculations.  Circular - Circular, Square -Circular, parallel lines and Centered Strip Line
along with VSWR,  Coupler Directivity and Dish co-efficient calculations are provided.  Also included are quarter wave transition and coaxial length calculations.   A Help file is included in the package.
 

The original IDF program I wrote for DOS in 1985 has now been updated to run on Window operating systems.  Design criteria is based on an article by Ian White (G3SEK) in Radio Communications February 1984.  The program allows the design of a 4 pole interdigital filter from box depth, rod size, center frequency, 3dB point & 40dB point.  Most suitable for frequencies above 300 MHz as below this the size becomes some what impractical.  The program has a graphical display of all dimensions. Construction hints are provided.

 

(Windows version of VK3UMs famous DOS EME Planner and Autotrack … available at the end of this listing)

The Windows version of the old DOS versions of the VK3UM EME Planner and the VK3UM AutoTrack is now called EME2007 and is now available for those that have one of the 120+ boards "out there" or those that want to run the familiar old display screens and features. It has been a long time in coming as I was happy with my own version running my own dish. However as a result of so many requests, and with the help from Michel (HB9JAW) and  Peter (SM2CEW) that have beta tested this new version, I have decided to release it for those in need. The software has many "unique" additional features for Spatial and Real time Noise displays, an extensive data base, as well as the prediction planning features. All planet and selected quiet and noise source tracking is provided in this version so if you want to track Mars or Jupiter Noise this will do it for you.

It handles Pulse, Digital and Analog input and is compatible with the earlier DOS version.

It now incorporates the VK5DJ hardware. Refer http://vk5dj.mountgambier.org/Amateur_radio.html Originally, the software would only run with the VK3UM tracking board (which is now no longer in production), however along with John VK5DJ board it also will  interface with Tom W2DRZ w2drz@madbbs.com interface board.

Finally be aware that the Doppler accuracy above 23cm. It may be not as accurate as required by some nor is the basic Noise data Base. There is no help file! Suggestions and bug reports are always welcome.
