your welcome. I have happy memories looking my sliderule too. wrote:

Dad had the same one. By the time I got to that point in school it was all scientific calculators. But I would see dad at the dinning table hunched over doing what he loved to do. I would crawl up on

I still have mine from 1971.

I used one in college..45 years ago :-)

Real nice. I wish I knew where mine disappeared to. Had a cheap plastic one and a good one (Pickett Brand??)

Nice find! I still have my dad's Post slide rule AND the leather belt holster AND the hard cover? instruction book. I used it with a $45 four function calculator in my undergrad physics class in the

There is an excellent group, [email protected], which covers the history, uses and collecting of slide rules; a great resource for small time collectors like me and for serious collectors and users.

This is the second thread about slide rules in the past month. Here is the link to the previous thread. /g/nanovna-users/message/29044

It needs to be rotated 45 degrees, not 90, to work with the polarity switch you have. If all you want is circular polarization, you don't need to rotate it, just use the phasing harness.

I am not at home at the moment to investigate the antenna. I should have paid more attention when selecting antennas. All the parasitic elements are in and X config but now that you mention it the

Well I considered that rotating it 45 degrees would fix it, but is it simple enough? The antenna boom is square and I am not sure how that will be easily attached to the mast or other mount system.

A slice of pi will do.

Yes, you simply rotate the Antenne by 45 degrees and it will worked fine. Regards Matthias www.dd1us.de -------- Ursprüngliche Nachricht -------- Von: "Dave W6OQ via groups.io"

Glenn: I reviewed the antenna that you linked to (WMO-18011) and I am pretty sure that it isn't compatible with the polarization switch that you linked to. The antenna has an unusual feed element that

That was what I suspected however as a regular user I can open and view the file in the error message. I am sure it is a permission thing. Have to keep looking. Thanks Glenn VE9GJ

Then check permissions on the paths in the error for a start. It sounds like something does not have permissions to a non-root user.

Will do. I discovered it works OK when run as root. 73 Glenn VE9GJ

Open a new issue on their github if it wasn't reported before.

Hey, that's a greedy slide rule! It wants money! One dollar to pose for a photo. How much does it ask to calculate a square root? :-)
