Ground Tuning Unit.
« on: November 19, 2018, 06:51:03 AM »
Hello,

Here is an interesting document on a portable station using a ground tuning unit...
If someone could turn it into a PDF and email it to me: gil@thisdomain.com (switch thisdomain.com for radiopreppers.com). I can only open it on my phone but not my Mac...
Have anyone here used a ground tuner? Comments?
Thanks to Alex, VK2PRC for sending me this file.

Thank you!

Gil.

If someone could turn it into a PDF and email it to me: gil@thisdomain.com (switch thisdomain.com for radiopreppers.com). I can only open it on my phone but not my Mac...

I just emailed you the requested PDF (12 pages), converted from DOCX to PDF, made by my MacBook Pro using Microsoft Word.app from Microsoft Office Home and Student 2016 for Mac suite.

Afterwards I discovered that a somewhat earlier version is available online at this URL:

https://www.vk5pas.com/uploads/1/3/9/8/13982788/-guide_to_building_a_portable_station_complete_with__gtu__1_.pdf

That one is signed: "Alex, VK2HAS", while the one I converted ends with: "Alex, VK2HAS now changed to VK2PRC". However, they both begin thus: "Date: 06.02.2016   By: Alex Ball VK2HAS".

BTW, there are several more or less free online services to convert from DOC or DOCX to PDF, here are the five top hits in my Google search:

https://smallpdf.com/word-to-pdf
https://www.ilovepdf.com/word_to_pdf
https://www.freepdfconvert.com/
https://online2pdf.com/doc-to-pdf
https://convertonlinefree.com/

I have used the first one earlier, when in a hurry, and I just tried it with your DOCX. It worked fine, except it downloaded with about half the size of what my Word.app yielded. I guess this matters only if you need high quality printouts.

Gil, the Mac version of the free OpenOffice suite opens DOCX files with no problems.  I use it frequently on Microsoft formatted files, including DOCX text and XLS spreadsheet.  As long as there isn't any weird formatting or macros involved, it works fine.  It also exports files as PDF through the menu "File/Export as PDF" option.

Many people have switched to the free LibreOffice fork of OpenOffice because of a difference in "free" license terms, but LibreOffice made some UI decisions I have a hard time living with so I went back to OpenOffice.

In any event, both of these handle DOCX/XLS files and export as PDF easily.
