Re: Computer-controlled small L-band switches?

Hey, I remember you guys in Syracuse always putting in for an L-Band router way back when I was in charge of capital for the company! You never did get one eh? Damn things were always so expensive. Nope, it never did happen... and now we have just over two dozen dishes, a bazillion Quintech active ...

Re: Computer-controlled small L-band switches?

Can't remember to bring home dinner, but I still remember what Radio Shack part number 276-1576 was... My wife and I both worked for Radio Shack about 40 years ago (not at the same time, though... we hadn't met yet). Even now if one of us goes "15-1140", the other will probably come back with "75 o...

Re: Computer-controlled small L-band switches?

The last three places I've worked in have all used Quintech gear. The current place I am in uses an Evertz. Did you notice that last month Evertz bought Quintech? For years I have dreamed of having a Quintech L-band routing switcher in our plant, but sadly I don't see it happening. We had a Quintec...

Re: BVH-2000 EOT (end of tape) stop not working?

Make sure the timer roller isn't slipping -- give it a very good cleaning with isopropyl alcohol to try and get rid of the surface glaze. Also, make sure that it spins freely (if the bearings are at all stiff, the tape is more likely to slip on the roller). You might want to pop the C-clip that hold...

Re: RING MY BELL

I heard Jimmy Kimmel gave ABC affiliates a chance to donate to the Treasury last night. You're right. I just checked our confidence recorder, and they used the two-tone attention signal several times starting about a minute and a half into the show. These people should know better... but we're the ...

Re: New UPS suggestion

We used to use a lot of Liebert (Emerson) GXT series UPSs in that size: 208 in, 120/208 out. They have held up quite well, and because they're "on-line" units, noise on the input doesn't make it through to the output. Also, there's no glitch on the output from a relay kicking the feed over to the in...

And then, NBC Newschannel distributes a package about the test, voiced by Jay Grey, with nat sound of the TONES at the end. :evil: So stupid...they ought to know better. They did send a corrected pack, but still... I anticipated this, and explicitly warned our news department ahead of time. The urg...

We did see IPAWS go offline *after* the test, between 3:28 and 3:40 Central. (has anyone else seen that?)
Yes, our ENDECs have been seeing a lot more polling failures than normal for the last week or so.

Re: RING MY BELL

We had quite the cellular cacophony throughout our building, followed two minutes later by every single one of 27 program streams relaying EAS as each station's ENDEC got and relayed the alert. It was something of a contest to see which stations would be first... in our case, the Elmira station won,...

IPAWS Server bouncing?

For the last half hour or so, all five Sage ENDECs in our regional group have been showing the IPAWS server going up and down -- and they're all in different locations, so it isn't just the internet feed to our building. We're running the most recent firmware with the new certificate. Is anyone else...

Re: Genlock

We generally think of genlock as a means of keeping sources in phase, since that's necessary for clean transitions. It's easy to forget that in order to enforce a phase relationship, you're more fundamentally forcing each source's internal oscillator to run at exactly the same frequency. That become...

Re: Sony BVH 2000 PS. Gray screen, with color flicker

I am less familiar with the PAL version than with the American NTSC version, but the color flicker problem sounds like you are looking at video that is not time-base corrected. Also, if you are using a time-base corrector, make sure your monitor is getting the "TBC" and not the "demod" output. Final...

Re: BVH-2000 playback muting to grey screen

Bear in mind that the interface to the external BVT (via the round multi-pin connector) doesn't necessarily use the exact same handshaking circuits that the internal BKH timebase corrector uses... so there are credible cases where the fault could still be in the SV-43 board. One thing that could tel...

Re: BVH-2000 playback muting to grey screen

The SV-43 card is common to both NTSC and PAL/SECAM models; it is the gateway between the main system controllers (SY-79 and SY-80), and the analog servos for the reels, capstan, and drum. When you hit the PLAY button, the machine goes through several modes before it gets to the point of being compl...

Re: Tantalum caps

Sounds like our old Panasonic DVC Pro cameras... Ugh... DVC-Pro. Our original centralcasting facility used several dozen DVC-Pro decks, twelve of them in a spawn-of-Satan robotic contraption called a TiltRac. We ended up buying an entire reel of surface mount capacitors from Digikey after the first...
