Re: Definition of a heartstopper

Every quarter, one of our local Chevy dealers runs 30-second spots that are silent...black background with supers that slowly fade in and out. They get my attention! :D

Re: Repack

Not having a backup STL option is...wow. We heard a horror story of a station that didn't have a backup encoder and spent (I think) 4 days off the air. We still have our original Flexicoder and a NetVX still around for doomsday duty, and two matching Selenios as our main and backup encoders. What's ...

Re: Harris Z FM FET replacement

I've only had one Z PA failure, and I didn't fix it myself because I didn't have the time, but Paul Thurst's broadcast engineering blog has details on swapping Z PA FETs. I don't believe he had to align anything. One thing to be mindful of is the age of the transmitter. Harris changed the FET suppli...

Re: BE AM-6A RF Out Problem

I'm working on an AM-1A with a similar problem...symptom was high reflected power, even when running into a good dummy load. I was advised to first try the balance adjustment procedure on the Directional Coupler replacement manual (you can download it from the BE website). That got the reflected pow...

Re: SmartCaster Systems help.

I have a RF client that is still running a version that predates me... Probably early 90's in what looks like DOS. I have never had to touch it since a guy at the station is intimately familiar with it and keeps it limping along. One of my clients has two DOS Smartcaster chassis sitting in the base...

Re: SmartCaster Systems help.

http://smartsbroadcast.com/library/ Here you'll find manuals for the current Skylla product and the older Smartcaster 2002 product that merged the DOS Smartcaster program with On Air Digital's RS-HD Linux-based audio playout...the Smartcaster software runs in a DOS emulation window within Linux.

Re: NBC Late Night and closed captions

Yup, they are only doing 608 apparently. This started on May 13th with Fallon. Commercials come though with 708. I have my encoders set to translate 608 to 708 when 708 is missing, so that explains why I still have CC on my Volicon recordings. I just found out NBC has moved network master control t...

Re: IRD control

Make it three thumbs-up for Compusat. It works, and it controls a lot more than receivers. It costs, but if you have to automate receiver switching, dish moves, recordings, etc...this is the way to go.

Re: NBC Namedropper Trigger Configuration Help

Thanks for all of the great replies everyone! I actually have a new question regarding Namedropper. This is the box that just wont stop! After all of the drama with getting the triggers to receive properly, I now have an issue with LTC. When we set it up initially, we just set the time manually unt...

Re: SX 2.5 Won't Power on No Lights

Always a good idea to check for loose connections on the regular. It'll also save your ATU components and avoid downtime... The input and output connections on the SX PA boards are also good places to check for tightness. The output side of the SX1 I care for burned off at the lug and I had to do s...

Re: SX 2.5 Won't Power on No Lights

Loose bolts are one thing, but a guy should never have loose nuts. Ouch! That's part of our routine with our Harris Platinum SS TV transmitter...check all of the DC bus connections for tightness. Lotta current to arc-weld with if it got loose. That, and cleaning, are about all we do for maintenance...
