Re: X-Y protocol??

I had a frustrating issue with something similar.... I can't find it on the BMD website now, but they at one time sold a DVI extender which pushed SDI over 1694A. Worked fine for the intended purpose, but one guy thought he could use it as a DVI-to-SDI converter. Problem is, it told the computer it ...

Re: X-Y protocol??

So I wasn't imagining things about RS-422. It's been a few years (like fifteen) since I've had to work on an X/Y system.

When we went digital (and before we went HD) I had to get a small Jupiter working as the back-end for a Saturn MCR. I still have nightmares.

Re: X-Y protocol??

That's indeed a rather broad question:) It's a way of connecting control panels to a router, introduced by Leitch. (later Harris later Imagine which still sells X/Y products) Physical connections are a 75-ohm coax bus terminated at both ends. I have a vague recollection there's a way to make it work...

Re: Replacement for HD-Star

They let me have ours back:) From the Main Menu; - Sig Info - ANC Status Any ancillary signal that's present shows up in white. (it's grayed out if it's not present) It'll also show red if the packet is present but has errors. The Setup button lets you define the three User-n options at the bottom o...

Re: Replacement for HD-Star

Of course, one of my guys is using ours somewhere else right now... There is a screen that shows a present/not present for a variety of well-known DID/SDID combinations. At the bottom of that screen there are (IIRC) three "User" combinations you can set to anything you want. I was having problems wi...

Re: Replacement for HD-Star

We also have a Phabrix. Upsides: - Far more available tests. (for example, it will check for specific DID/SDID combinations in the ancillary data. Like NBC Namedropper cues.) - Reads AES audio. - Appears to be better built physically. - Networkable. (although we haven't looked into that function yet...

FM translators of AM stations

I was curious -- ran a query against the facility and int_translator tables of the CDBS database this evening. 73.9% of all authorized AM stations are the listed primary of at least one FM translator license, construction permit, or application. That figure does not include AM stations which are rel...

Re: Singling out 2 stations on same frequency

Pretty decent TV antenna. (FM radio falls very close to TV channel 6, so a decent TV antenna usually also performs well for FM. A dedicated FM radio antenna would work better but I don't see any decent ones on Amazon.) Turning it vertically causes it to respond to vertical polarization. (installed h...

Re: USB Keyboards/Mice for Studio

DO NOT use more than one wireless keyboard/mouse in the same studio! I came in to work one day to find someone had, for aesthetic reasons, replaced seven wired keyboards/mice in the studio with seven wireless units. After about two hours' work I was able to get each keyboard/mouse paired with the ri...

Re: NBC: spurious Namedropper trigger?

The Namedropper's "backdoor.cgi" page says it's seeing the trigger signal on 52 0F -- but it's not inserting anything. Patch out the X50 & it works fine.

Strange....

Re: Revitalized AM Translators

This rule has recently changed. (last spring IIRC) Originally the translator's coverage area had to be within 25 miles of the AM station *and* the 2mV/m contour. It was changed to with 25 miles of the AM station *or* the 2mV/m. I'm betting the translator in question was authorized before the rules c...

Silent spot

Yep, they're at it again... Someone has produced a spot with ~20sec. of silence at the head.

I see why they did it -- it makes artistic sense in context -- but I'm tired of these emails from the silence sensor.....

Re: Getting Through Windows Firewall

If the computer isn't doing anything critical then you might consider just configuring it for remote desktop and have the audio diverted to the client computer...that way there isn't any special config for whatever you are listening on. I did this during the eclipse. Had a SDR connected to the PC a...
