I agree with you Ken. The K6TU site is the way to go for generating the
terrain files.
All you do is enter the coordinates for the tower and name the files. A
couple of minutes later, you get an email with a link to your new files.

and it is free!

Go tohttp://k6tu.net/?q=TerrainProfiles
and let it generate the files for you. Much easier. And the price is right.

I wonder if someone can help me with getting the terrain for HFTA.
It appears that the Microdem site has a virus in their program download.
When I try to install the version from the web site, it tries to delete
bootmgr, pagefile.sys, etc. Then it ends with a unexpected memory leak
exception. I

I just double checked my HFTA software, and it does present a set of elevation
angle statistics for 1.8MHZ that are significantly different than the
statistics it shows for 3.5MHZ. Not sure how these are derived. 73 Charlie

As I recall they never blew up the receiver here, unlike TF4M, GM3POI, and
others in that direction from KL7 who were consistently available during times
of low absorption over the N Pole.
Then again, who knows what antenna array they were using or the ERP when heard.
I'd still like to know th

Radio Arcala - I have always believed that a horizontal antenna on 160m at
very high latitudes would generally be worse (note that I didn't say always)
than a vertical due to the effect of the Earth's magnetic field. How
"theory" translates to "the real world" is always subject to careful

How strong of a signal can that enormous Yagi radiate into the USA on 160?

HFTA - It can import the elevation angle files generated from IONCAP/VOACAP

yes, the files only go down to 80m because of IONCAP/VOACAP limitations.
