VK3UM EME Calculator 5.33 EMECalc-Ver5.33 Install1.zip
Hi All
Latest update now includes cross polarity calculations commensurate
with circular to linear polarisation.
3400 MHz (as suggested) and an update of the Help file.
Regards, Doug VK3UM
This latest EME and Receiver Performance Calculator (Ver 5.32)
incorporates colour changes to enhance the contrast between screens
and to assist persons with possible eyesight difficulties. In
addition, the ability to manually change sfu values has been removed to prevent
possible calculation errors. It is no longer required given the in
built sfu data base and ability to down load current sfu values.
The Help file has been updated to reflect changes.
VK3UM EMRCalculator.. VK3UM EMRCalc Ver 6.40 Install.zip
I have made relative a relative minor change to the dBi and dBd use of the VE7BQH G/T tables. This was to ensure that the table was commensurate to the dBd figures. It was possible to use them in a dBi context and this update resolves the potential abnormality.
VK3UM EME Planner .. EME2008-5Apr2008 Install2.zip
- Changes to this update are the inclusion of all 2.3GHz ranges plus more precise frequency definitions for 10,24,47 GHz which
will be reflected in the Doppler calculations.
- minor changes to the VK5DJ interface.
- Sun noise and eclipse correction implemented. .. no Help file ..still!!
I have had one report that the Planner may not run on Vista. (like so many other programs!!). Does any one have any further info on that aspect, please?
As always, your comments and suggestions are always welcome.

(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 EME2006 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. The next version will incorporate VK5DJ hardware when it becomes available. Refer http://vk5dj.mountgambier.org/Amateur_radio.htmlOriginally the software would only run with the VK3UM tracking board (which is now no longer in production), however Tom W2DRZ w2drz@madbbs.com now provides suitable interface boards.
I have removed the Y factor and EME Budget screens that were previously available in DOS versions. The accurate distance calculator has been retained. These specific options are available separately, and with significant added detail and accuracy, in the VK3UM EMECalc program. (refer this site.)
Finally be aware that the Doppler accuracy above 23cm 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.

The version (21Oct 2007) corrects a bug when using the distance calculator generated coordinates from a user input Grid square when doing common windows in the Planner screen.
Thanks Gabriel for pointing it out.

History
5.00
This latest update provides a significant improvement in the calculation accuracy of Sun Noise.
With the assistance of IPS Australia and John (VK5DJ), the current flux data is now down loaded directly into the program and the interpolated
and extrapolated values calculated (commensurate with IPS), for all frequencies provided within the program. The actual figures are now derived
directly from actual measurements. Previously 'fudge factors' were used, and although accurate for a narrow range of sfu's, this latest version
complies with the IPS method of measurement and will follow all values of future sfu.
The program also includes a sfu history file that covers flux values from 65 - 220 sfu in 5 sfu steps. This may be used to re-view any previous measurements
with higher degree accuracy. The IPS data also provides indications of actual data quality. This is used to provide warnings when accuracy may be compromised
on a specific or a range of frequencies.
More information may be obtained from the integrated Help file which has been updated to include this latest facility as well as other user suggested refinements.
The latest update of the calculator has the following notable refinements and additions.
- Aperture Correction Factor for both Sun and Moon is now fully implemented.
- Additional frequencies added for the full coverage of the 2.3GHz band as well as Radio Astronomy and Deep Space allocations.
- revamp of the Y Factor Calculations. Given the data available, Aperture Source calculations are only valid for 144 and 432 MHz and are now only
provided for those bands. Point Source calculations continue to be provided, now with an indication as to validity of data source. (verified or an extrapolated value.)
- updated Help file.
Due to an over sight, the Aperture Correction Factor for the Sun calculations was previously never implemented. The Moon calculation also did not cover
all aperture sizes. The factor correction value is now displayed both as a decimal value and as the dB reduction applicable. For those using frequencies
above 23cm this correction factor becomes most apparent and the calculator will now provide a most accurate value of expected Sun and Moon Noise
commensurate with your system. Try reverse engineering to find a problem area and improve your system if necessary.
I would be most interested in hearing (directly) from those using the higher frequencies, as to the correlation of calculated values with their own systems.
I would also be interested to hear from any one that has definitive Noise Flux values for the Noises Sources I use in the program relating to frequencies greater
than 10GHz as well as for 70 and 50MHz. Some sources between 3Ghz and above also are missing definitive values.
(The extrapolated values are shown in red in the program or the calculation boxes are left blank).
Many thanks to Peter G3LTF for his help and advice in confirming the figures on his 3456 MHz system. (spot on! .. but you would expect that from Peter!)
This provides most all possible variables to calculate the S+N/N ratio of two stations and includes, Station Power, Antennae, frequency from 50MHz to 48GHz. Receive noise temperature and cascaded noise figure, transmission losses, spill over, feed through, ground temperature and perigee/apogee parameters. Sun noise respective to Solar flux, moon noise and ground noise calculations are also provided. Object size / Aperture conversion factor is included. Y factor measurements of noise sources and has the ability to vary preset values to "reverse engineer" your results. Additionally there is a pre amplifier parameter screen to allow you to see the ends effect changes you make that will have a subsequent effect on your overall performance. Coaxial cable types and their losses are included in the selected calculations. A free space calculator is also provided for other applications. Space precludes a more detailed description but a basic ‘get you started’ help file is provided in pdf format. It also provides Moon noise calculation, object/aperture correction factor, apogee/perigee path variation, variable ground temperature, and improved Noise Y factor calculations commensurate with current noise flux densities and antennae aperture. Common Commercial yagi available types are provided.
Version 4.00 of the calculator has the following notable refinements and additions.

The software some may not want to know about … but you should!
The initial version was first released in Prague 2000. his soft ware addresses Electro Magnetic Radiation (EMR) safety issues. It defaults to both the FCC and Australian RF Safety Standards as well as being fully adjustable to suit you own National Standard. Covers 1.8MHz to 48GHz for both circular and rectangular apertures.
Selectable common antennae types are provided as well as variable input is included. An EME calculator is provided (not as comprehensive as EMECalc) as well as a height / distance / on axis calculation is also included. Note. The Australian Standard is almost identical to the European Union and Swedish Standards. (Pulse calculations are not provided in this Amateur version)
It is your responsibility to ensure that your Radiation conforms to the World recommended guidelines for the sake of your family, your neighbours … and yourself .. Check it out .. you most likely will be alarmed to find the extent of your own radiation.
The latest update for the RF Radiation and Performance Calculator (EMRCalc) now includes
- a comprehensive integrated Help File. (Contents, Index, Search)
- additional Controlled Environment calculations for all Standards.
- examples of various forms of types of calculations provided. (related directly to FCC and ACMA examples).
they can be loaded directly by incorporated example files.
- FCC 'Evaluation' recommendations are now included.
- improved colour scheme for those that may be colour impaired (recommended).
This Program has now been incorporated into EMRCalc Ver 6:0 (January 2007 see above)

Transmission Line Calculator ( ZCalculator.exe ) Version 1:09
Born out of the frustration of building feeds with commercially available tube sizes! It handles round to round as well as square to round tube sizes. Additionally it provides parallel transmission line calculations. This software allows you to select the size of the inner or outer conductor or required impedance and calculate one of the parameters after selecting two of the others! Fractional conversions are also included for Imperial tube sizes. Variable dielectric constant and Metric/Imperial conversion are provided as well as multiple wave length calculations. It also provides VSWR calculations and error calculations inherent with directional couplers. Another feature is the inclusion of a Dish reflection calculator. ‘It has it all for getting your feed spot on the money first time … that’s why I wrote it!’
VK3UM Transmission Line Calculator Ver 1.09 Install1.zip build 2008.1.9.3
The original IDF program I wrote for DOS in 1985 has now been up graded for Windows. Design criteria based on an article from the article by Ian White (G3SEK) in Radio Communications February 1984. Allows the design of a 4 pole inter digital filter from box depth, rod size, centre frequency, 3dB point and 40dB point. Most suitable for frequencies above 300 MHz. Below 300 MHz the size becomes some what impractical. Graphical display of all dimensions. (very accurate)
