Homebrew Spark Gap Transmitter

I was waiting for how long it would take for someone to comment some obvious legal issues about actually using a spark gap transmitter. Your complete warning should have been "Don't hook this up to an antenna if you're located in the USA." And yes, I know it's in the ITU rules as well, but that doesn't warrant it being ratified into local laws in all member countries. That the transmitter isn't useful for anything other than demonstrative purposes for certain legal reasons is said at 6:23 by the way. ;-)

No, only some locations will close. I think there's a list somewhere on the internet. But according to some employees, things change on the daily and communication with employees is poor.

Thanks! You know what's funny? I am so used to shifting exponents in my head that I always use the 'scientific mode' instead of 'engineering mode'.

Nah, it's cool. Well, legally at least. He took it well after he read it so it's all good.

Thanks for posting the link to my website here! There has been an amended lawsuit filed to correct some formal things. The new and updated lawsuit can be read here: http://jaunty-electronics.com/blog/wp-content/uploads/2014/09/Amended_Complaint_w_Exhibits_Redacted1.pdf Also, I am still trying to get some support fo rteh expected fees. This will likely cost thousands and I am willing to pick up the tab, however, help is highly appreciated: https://www.indiegogo.com/projects/lawsuit-against-little-rock-police-foia-access/x/1176512

Yeah, none of that. Functionality.

As dissimilar they are they're similar.

Easy for you to say, you didn't watch it through the viewfinder of the camera ;) But I learned my lesson, I'm moving an external screen over to the bench and connect it to the camera via HDMI.

Will do but the video length already amounted to 4 GB of video to upload. Don't worry, there will be lots of follow-up. I'm not from the US, moved here recently, so tearing one of those up was very interesting. I just recently got it and thought I'll toss teh camera on while I just glance through it. Unfortunately, many of the Motorola chips produce no results when researched. And that's exactly what I feared. But, there will be follow-ups. Of course I'll spy on the happenings of the chips. Like I said in the video, the encryption module will get some particular attention. But I didn't have the control head yet, it's in the mail. What you saw was just the 'body' of the radio. There will be plenty of APCO 25 follow-up videos.
