Re: Commercially available replacement for the ATU-20 Coupler

Made by LPB, used in a carrier current AM system. Based on what I have read, also refereed to as a TCU-20.

Not much left of the ATU-20 board after a 4160V feeder fell on the 120/240V secondary

Re: Smart AC Power Circuit Breaker with Web Control?

ABB (and I'm sure others) make motor operated circuit breakers.

The question is what is the breaker tripping in the first place?

Re: VOIP replacing analog

If the studio is staying with an analog broadcast phone system behind the Cisco phone system, the Cisco VG202XM or a Cisco VG204XM would work fine. Ask your telecomm system administrator to make sure they are sending CPC signalling when the call ends - got bit by this one myself. If you are going to...

Knife edge limits for § 15.221 Operation in the band 525-1705 kHz.

The Nonprofit I volunteer at has a potential grant to purchase a TR6000 Model 15.73 and ANXX Antenna. Our attorney is drafting a letter to the FCC to verify that our educational status qualifies us to operate under § 15.221 Before I ask to spend non-grant money on hiring a professional (PE or GROL) ...

Suppressing Windows 10 Update and Forced Reboots

I pretty much gave up fighting MS re the update and forced reboot issue - what seems to be working for me so far Deploy Server 2016, and the "user experience" package. Pretty much acts like W10, with the ability to update and reboot issue on your schedule, not theirs. https://docs.microsoft.com/en-u...

Re: computer dropping off network

I'm not seeing an official release date on 1809. I had a handful of W10 boxes pick it up. Users are stating it updated on it's own. 1803 has it's own bunch of issues with network connectivity. https://www.techrepublic.com/article/how-to-resolve-network-problems-caused-by-the-windows-10-april-2018-up...

Re: computer dropping off network

The forced upgrade to 1809 (Redstone 5) seems to have included all the network problems from the 1803 (April) updates that everyone skipped.
If you have a restore point set, my suggestions would be to roll back.

Re: High School Studio patchbay - help!

A forward looking option would be to deploy coax / connectors suitable for SDI and use HDMI over COAX boxes at both ends. https://www.blackbox.com/en-us/store/Detail.aspx/HDMI-to-3G-SDI-HD-SDI-Converter/VSC-HDMI-SDI https://www.blackbox.com/en-us/store/Detail.aspx/3G-SDI-HD-SDI-to-HDMI-Converter/VSC...

Re: High School Studio patchbay - help!

Here's my questions: 1. How big of a patch bay do I need for this? 2. Do I have them do 10 each of HDMI and XLR? A few VGA? 3. Should I have them drop SDI for down the road when we upgrade cameras? As to capacity: Take what you are currently using and double it. As to future proofing the work, I wo...

Re: PE for New Jersey

Tower + 1.5 yards of transit mix is cheaper then a pole. Since Hurricane Sandy pole pricing is out of control.

Edit: and it still would need a PE as it's *not* a pole used by a public utility....

PE for New Jersey

Need a NJ licensed PE to stamp a *very* small tower job. It being erected on municipal land on behalf of a non-profit, so it needs the permit and seal. When I say small, I mean small - this is literally 20 feet of self supporting Rohn 26G with a PTZ video camera on top. Drop zone is parking lot and ...
