Visio (in pixels) !!

For years I have suffered thru an absence of ‘pixel rulers’ in Visio.
I understand that a pixel is a screen concept, of different dimensions on various display screens… not going into that here. However, I frequently use Visio to construct various image files to fit into an exact space – and resort to using a 2nd program to finally scale my image file to the exact fit ( in units of pixels).

Apparently, in 2008 Noah posted on his blog ( an article describing how to deal with this. Unfortunately it was years and years later before I found it (in 2014). But I did, and it works for me, and I will use it often.

A screen shot and quick explanation from Noah :


Why it works Picas are 6 to the inch. By setting the ratio at 1:16, Visio presents a diagram at 96 picas per inch, the same as the Windows standard of 96 pixels per inch. You could set an appropriate ratio with any of the available units, but it works well with picas, and I find it useful that all units are labeled as p.

Thanks Noah ..!..  /;^)

Thanks Dad, and so many more.

For Veterans Day this year, I got out some of Dad’s insignia – did a quick buff-up and then into the HP scanner. I believe this photo to be from 1945 . . .


Thanks for your service.



That is almost too much alphabet soup.
What that means is that every year those of us that do ham radio, like to test our skills with a large scale exercise – most often coordinated at the state level.
Please read more about ARRL/ARES.            Exercise, Exercise, Exercise…

Hmm, mobile email via VHF radio – could be useful. (and fun) /;^)

My goal this year was to operate my VHF Winlink email from the Subaru.
I also needed to activate the MSFC club station WA4NZD for the exercise.
So, I setup the stuff in the passenger seat, and drove to the club station. There had been some power-grid work earlier in the month at the Fox AMC (host site for our Winlink Internet Gateway) and it had only returned to service the day before the Simulated Emergency Test (SET).  I have a 4G/LTE modem available, and could have also operated the mobile station as an internet gateway if needed.
Someday soon, I’ll test the HF mobile capability as well.

The N4WGY-10 gateway was easy to access from WA4NZD, and a few exercise-related messages were sent. I think I heard Bill/KB4NEI check in directly from FAMC as well.  This is a great resource for the community and I’m glad to see even a few dedicated users checking it out weekly, with their own station ‘s readiness review.  Perhaps I can update the W4HMC website with the latest version of the Communications Plan diagram we used as a baseline this year for our SET.  If you are not yet registered with the Madison County ARES group – and want to be a part of this, please check our HMC website.

There were several nets activated, and lots of check-ins.
Sounds like a good intro for a future post…

Thanks  /;^)

What?_Another blog?_

Almost as though I had too much stuff for just one blog . . .


NetSysHax blog with Wireshark header image

NetSysHax is a blog that was established to offer technical stories and solutions that seem relevant. Alex & I work together during our day jobs, but we both like to offer consulting services when those opportunities arrive. We like to share technical insight and solutions, especially when most problems only need the right tools to become a success story.
Self Promotion needs to be a success story too.

I need to post more stuff on the NetSysHax blog, as well as on this one, my RadioActive site. So bear with me as I work on both in parallel (with appropriate cross-links).
Thanks.. Please visit often for new stuff
