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.

History of recent updates
- EME Calculator Ver 7.00
With the help of Peter G3LTF have revised several of our calculation methods and this version relates
extremely closely to theoretical and practical measurements. Due to the changes I have made I have
implemented a new series version (7.00)
EME Calculator Ver 6.05
Increased definition of Dish size input to cater for small dishes. (now nearest 100mm)
Coaxial Cable attenuation updated (Rx Performance option) Build date 26th August 2009
EMECalc Ver 6.04
Moon noise now included in calculation (may be disabled)
UTAS - PI9CAM uW cal file added.
Additional WSJT and common bandwidths preset selection
Version history may be viewed from program
6.04 Changes to Receiver Performances Calculator relating to ground
temperature commensurate to spill over and feed through. Addition of
Lambda Dish calculation and blockage warning. Help file updated.
** Release date 13 August 2009
This now includes another 10 Feed types and an updated Planet calculations including actual Bochum site information courtesy of James G3RUH.
During the past month or so Peter G3LTF and I have been investigating the discrepancy between the theoretical feed efficiency measurements and those that are obtained in 'real world' situations. Our focus was on the actual realised values of dish efficiency, spillover and feed through. Given the reference data from Paul W1GHZ we have been able to ascertain, through practical measurements, what the realised values of efficiency are for the dish feed types provided in the program.
In addition, and again with the considerable assistance of Peter G3LTF, we have also refined the calculations of Effective ground temperature and C/S - Ground. Results now reflect actual measurements (to a very high degree) efficiency, spill over, feed through, sky, and the ground noise interaction. A significant, although seemingly minor at first glance, improvement in accuracy.
Those that use yagi arrays, sorry, you will still need to derive their own 'spillover', (side lobes), and 'feed thru' , (front to back) values commensurate with their own installation. The
variables are just too large to provide a meaningful result if derived from a data base. You will still need to obtain your data from actual on site polar plots.
This revision also includes another VE4MA 'standard option feed' and now caters for both flush and 0.15L (normal) ring configurations. The EIA Dual Dipole feed has also been included which fills the gap for those with 70cm feeds. RA3AQ feed types will be added later when time permits.
Finally I have included a Planet 'reality check' calculation option for those that believe EVE is feasible from your back yard! A demonstration station file Venus-EVE.cal, based on known (and assumed) values of the Bochum Dish, has been included for your interest. The integral Help file has been updated and includes a detailed explanation with respect the changes and additions.

History, detailed
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.
- 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

Transmission Line Calculator ( ZCalculator.exe ) Version 1:15
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!’

square conductors.
Four Pole Interdigital Filter (InterDigitalFilter.exe)
- InterDigitalFilter-Ver 1.67 InterDigitalFilter-Ver1.67 Install.zip
minor addition to screen for minimising.
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)
