Re: Audio cable for AM transmitter site? Star Quad or Ethernet or What?

Don't forget to put the shrink on BEFORE terminating the wire! :D For those of us who date back to using large multicore cables for studio cameras (think GE PE-350 or Ikegami HK-357), it's "don't forget to put the boot and shell on the cable before soldering all those wires!" Some of our younger st...

Re: NBC Namedropper Trigger Configuration / METAR server

The NWS METAR site is tgftp.nws.noaa.gov , which currently resolves to 140.90.101.79. I can use Filezilla to drill down through their folders and grab the actual coded text file Evertz uses. When the Namedropper temperature stops working, I bypass and reboot first. If that doesn't work, I ping tgft...

NBC Namedropper Trigger Configuration / METAR server

For those of you who have been missing the temperature on the Today Show graphics since last week: the current known working METAR IP address is now 140.90.101.79 . It's changed several times over the last few months, and Evertz got me this latest address this morning -- and both of our Namedroppers...

Re: Audio cable for AM transmitter site? Star Quad or Ethernet or What?

... 3M had just come out with nifty little dispensers with rolls of plastic adhesive numeral marker tapes (0 - 9). Those are the ScotchCode numbers of which I wrote. I certainly hope they've improved the adhesive since 1985! (And kudos for not ending that sentence with a preposition -- my English t...

Belden 8451 two wires, foil shield. Thousands of feet in use around the country in all kinds of studios.
Heck, we have literally miles of 8451 and 9451 just in our building alone!

Re: Audio cable for AM transmitter site? Star Quad or Ethernet or What?

Since we have a diversity of opinion here, I'll broaden it a bit: 1) Belden 8451 is excellent for analog line-level signals, but 9451 is easier to work with: the foil shield is bonded to the jacket, so it strips cleanly. Otherwise, the two are identical. In our plant, 20-50 feet is a relatively shor...

Re: NBC Namedropper Trigger Configuration Help

I'm probably wrong, but I always figured the Ku space was cheaper, which is why they started Ku and stuck with it. Another reason for choosing Ku in the beginning could have been TI. C-band TI was still a thing in the mid-80s...AT&T Long Lines didn't turn down the TD-2 microwave systems in this are...

Re: NBC Namedropper Trigger Configuration Help

One of these days, I'm hoping NBC will start IP-streaming the backup feeds. The new RIST (ARQ) protocol makes for a surprisingly robust link, even over public internet circuits, and you don't need the overhead of forward error correction. Having a feed that doesn't suffer from sun outages, rain fade...

Re: Adding Genlock

If you remember also, the original Teranex upconverters wouldn't encode captioning. You'd have to use an external captioning encoder. On our first generation Harmonic encoders, we had a serial feed from the Evertz captioning encoder into the Harmonic to send CC. (Long before the 708 standard became...

Re: Adding Genlock

Yikes that's a hefty price tag.. I don't know their history but am interested now. They were pricey indeed. It reminds me of when scientific pocket calculators first came out: the original HP35 sold for $395, and the programmable HP65 was $795 (equivalent to about $6,500 today). The HP35s on my des...

Re: NBC Namedropper Trigger Configuration Help

Glad you were able to figure it out. How do you not have a Skypath rack? You must be a new affiliate. Most of us are lucky enough to have 30-year-old dishes with a rack of 1290 receivers protected by a UPS that takes a month or more for NBC's contractor to ship a replacement when they die. :D Our c...

Re: NBC Namedropper Trigger Configuration Help

As a starting point, I would patch the Namedropper out of the air path and connect it straight to the RX8200 output, and see if it triggers. If it does, then hook Namedropper to various points in your chain to see where it stops triggering. Our plant happens to be a centralcasting hub that includes ...

Re: Adding Genlock

I have to chuckle when I see newer Teranex units selling for around $1500: our original six cost something like $60,000 apiece, and were not nearly as versatile. They also consumed a great deal of power for their size -- at least 500 watts apiece, with the result that we had to install the same sort...

Re: Cheap Chyron

I should backtrack... are they analog, or standard def digital, or what? If they're that old, maybe a better solution is to seek out a piece of used equipment.

Re: Cheap Chyron

You're looking for graphics generation, not captioning, right? If they are using a newer Ross production switcher (e.g., a Carbonite), a relatively inexpensive solution is the least expensive version of XPression. It runs on a standard PC, and pushes rendered graphics into switcher frame buffers so ...
