Re: Locked up browsers

Apparently Google monitors all my posts, Chrome version 56 disabled the chrome://plugins settings. You no longer can disable or enable plugins in this area. You now need to use chrome://flags to disable Flash. To disable Flash chrome://flags/#prefer-html-over-flash set to Enabled. This disables the...

Re: Locked up browsers

I have not had a locked up browser in a while, was this summer sometime. Currently use Chrome and Firefox but have no browser bars, flash, or java installed. In Chrome under chrome://plugins/ Widevine, Flash, and Native Client is disabled. Most browser crashes are due to Flash or Javascript errors. ...

Re: Designing website with Muse,Wix,Weebly vs. straight HTML

It really does not matter a lot what content management system (CMS) or writing the site in raw HTML, CSS, and Javascript. Hand coding will usually create a slightly faster site, but this is mostly due to knowledge of website design not the hand coding itself. If you want the site to be fast look in...

Internet Firewall Importance

Ports Scanned and Approx Percentage Seen 12-30-2016 TCP 60% 23, 2323, 23231 Telnet 15% 80, 8080, 8088, 8...

Re: Lower cost portable spectrum analyzer

I am not sure what you consider portable. Similar to the Rigol DSA815 is the Siglent SSA3021X with 10 Hz RBW. Or the RF Explorer handheld will work if you just want to survey a site.
Note: I do not own either so no hands on experience just hearsay.

Re: Missing FM pilot

How did you determine that they are still running the MPX subcarrier? I used my RTL-SDR receiver and software. It displays both the demodulated audio and discriminator output. And here is a article from Radio World on what you can do. And just in case you were wandering what SDR I was using here is...

Re: need drives

Way back in the day there was Capital Resource and Recovery which sold older computer parts. They are no longer around anymore but I did find PacificGeek and Discount Computer Depot still has some parts. Or a google search for computer recycling and the town, most sell parts.

Re: Missing FM pilot

Since the station is not doing anything wrong I might as well let everyone know the call letters for the station are KTCC.

Re: Missing FM pilot

Thanks for all the replies. It looks like other than not able to listen in stereo there is no real way to encourage them to fix it. I was hoping to be able to make a case for them to fix it. The bad part is the college has the money to fix it. But the professor really does not care much about the ra...

Re: Missing FM pilot

I don't believe that is covered in the rules anymore. As long as the occupied bandwidth doesn't exceed 75kHz, I wouldn't expect much concern by the FCC. Any particular reason why it's bothering you? It really does not bother me much other than it is not really correct. Kinda like a really messy cab...

Missing FM pilot

A nearby class A college radio station is transmitting FM stereo without a 19 kHz pilot. The 38 kHz stereo information is still being transmitted but no pilot. This has been this way for over a year. My question, is this within the FCC rules to have such a modulation. On the FCC website I read that ...
