Oh well since packet is VERY quiet at the moment, I'll send my spreadsheet
suite. It comes in 13 parts approx 9kb.
This is the latest version.
Anyone is welcome to distribute or archive the files on a website etc.
It includes an MS Office 2003 as well as a MS Excel version 4 suite.
Andy's Tool Box recent changes.
Ver 3.3b
* Added barometric pressure conversion.
(Because I'd purchased a Yaesu VX7R with the barometric pressure unit).
Ver 3.3
* Taken some common Amidon core data which was pictorial and converted to
text.
The Amidon data is NOT meant to be a complete listing, just a very simple
guide.
It also makes the whole spreadsheet size 50% smaller !
* Galactic noise now shows normalised figures for SSB and CW.
* Added Maidenhead calculator. Enter 2 grid squares and it returns
distance and beam headings.
