Re: High Intesity Tower Lights

I found this interesting, https://www.faa.gov/regulations_policie ... /70_7460-1 in the fact that the new installs of LED lighting are required to have infrared LED's as well to aid with night vision goggles.

No, full power NBC affiliate on upper VHF. None of the cable and satellite receive sites use anything other than an over the air feed.

Re: FCC announces first steps in the Repack

Late to the discussion, sorry! While I see multiple folks that believe that broadcasting an OTA is archaic (based on the majority watching those signals on cable and satellite), I shouldn't need to remind anyone that 100% of all viewers of my station are watching OTA. How do you deliver to all the c...

Re: Drone (sUAS) Coordination?

Kelly, I also have a part 107 certificate, and fly an Inspire 1 Pro for newsgathering. I successfully received a 107.29 waiver which allows operations after civil twilight, which the law also allows. The 2.4/5.8 unlicensed spectrum is not as much concern to me as the general airspace coordination. H...

Drone (sUAS) Coordination?

A quick question about those using flying cameras to gather news. As they become more active at news events, is there anyone doing anything to coordinate use, frequencies, etc. the way we did BAS ENG shots and wireless mic frequencies? (At least on the guys that are following the rules?) Yes, I have...

Re: NBC: spurious Namedropper trigger?

Yup, they put the Today Show crawl with time and temperature in from 17:31:15 to 17:33:20. I didn't check the rest of the show, however.

Re: Receiver Preamp?

My two cents...
If you are trying to improve C/N, the preamp will hurt more than help. If you are trying to correct a lossy feedline, they help. I suspect you are starving for signal at the receive, which the preamp will boost the desired as well as the noise...

Re: Want to know what makes (most) UHF engineers cringe?

Not as bad as discovering (after the transmitter went off), it had tripped a breaker on the heat exchanger fan, and the Technalogix had boiled the glycol out of the stainless reservoir into both exciters and upconverters! Swelled the tank up like a toad...

Re: DTV Pro Channel

Phil, I'll try to stay on track with your original question. There are no subcarriers on an 8VSB signal, only additional audio streams with a unique PID. IF you are still running an analog STL path (which is rare as most have a digital STL path for TV), the capability should exist to add a subcarrie...

Re: XMTTR IS OFF THE AR

At the risk of being repetitive (have I said that before?), the WJJY-TV history is at http://www.brainmist.com/wjjy_tv/wjjy_tv.htm . I love seeing the RCA stuff when it was new.
