[Ham-Mac] VHF Path Loss Capability Calculator

[James Duffey]

If there are any VHF weak signal enthusiasts out there, I have written  
a small MathPad worksheet to assist in calculating your station's  
capability. If you know the path loss for the station you want to  
work, you can also calculate the expected signal to noise ratio over  
that path.

Let me know if you want a copy and I can email it to you. MathPad is a  
free worksheet based mathematical calculator available from the  
University of New Hampshire. I use it for a lot of calculations and  
find it much easier to use than excel. Even if you are not interested  
in VHF, you might be interested in MathPad.

I recently discovered the SPLAT! web site that is an online version of  
the Linux program SPLAT! by John, KB2BD. SPLAT! calculates the path  
loss for any frequency between 20 MHz and 20 GHz between any two  
stations using the Longley-Rice Irregular Terrain model. That was  
inspiration for me to calculate my rover stations capability more  
precisely and hence I wrote the worksheet. - Duffey
