| Here are the brief descriptions of the programs capabilities & uses. Feel free to download. |

EME Calculator Version 7.04 Small but significant changes have be made to this new generation version where, as a result of careful 'real world' measurements, the achieved values of dish efficiency have been refined. Spill over values, referenced to a 45 degree elevation, have similarly been adjusted. The resultant changes
provide a high degree of theoretical to achievable correlation and now
approach practical measurement capabilities. My appreciation to Peter
G3LTF for all his considerable Moon noise now included in
calculation (may be disabled)

Site & Radiation
Calculator Ver 6.44
"EMRCalc.exe" 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.

Transmission Line
Calculator Ver 1.15
"ZCalc.exe" 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

Four Pole
Interdigital Filter Ver 1.67
"InterDigitalFilter.exe" 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.

"EME2009.exe" (Windows
version of VK3UMs famous DOS EME Planner and Autotrack … available at the
end of this listing)
