Does anybody on the list know what I can do to get past a
couple error messages I receive when trying to open a DEM
file in Microdem? The error messages are "Need 7z for GZ extraction"
and "xxx is Not an acceptable DEM". I went to the 7z website and
downloaded & installed the 7Z extraction utility, but that didn't help.
Any input would really be appreciated. Been trying to get Microdem
working for months without success.
You're doing this for HFTA, right? Last I heard about this, the formats
of the Microdem data and/or its extraction process have changed over the
years that HFTA has been using them. HFTA author, Dean Straw, has done
some talks about using HFTA, including the Microdem process, most
recently in a WebEx for PVRC. In addition, ARRL has done their best to
keep up with the changes, and I remember Dean pointing us to stuff on
the ARRL website. I think you can find a recording of the WebEx on the
PVRC website.
