Re: AES/EBU utility mixer

I tried very hard to find a similar device, but to no avail. What I ended up with in my facility was a Windows 10 LTSB 1RU Lenovo mini-server (not connected to any network at all, so no worries of updates) with a Lynx 16 card in it. Ours is for Katz Expressway sub-mixing, so its actually in the airc...

Re: Does the FCC keep track somewhere of subchannels?

While the FCC doesn't keep track, since broadcasters actually have to pay licencing to iBiquity to transmit in HD, and therefore iBiquity knows who is on the air with HD, the database on https://hdradio.com/stations is actually pretty accurate. There may be a few stations listed that aren't running ...

Re: Nautel Extended Digital Mode

Extended Digital would be set in the Importer actually... you are running in MP3 mode when you probably want to be running in MP1. The exgine doesn't care... it just spits out what is fed to it. Unless you have specifically configured this, the extra bandwidth is also being wasted. I run MP3 on one ...

Re: High School Studio patchbay - help!

I agree, however I have had very good experience with the super cheap SDI-HDMI converters. Given you're working on a school budget, this could probably make more economical sense. Pull something like Canare L-4CFB or equivalent, which would be far cheaper per foot than HDMI, and then terminate in BN...

Re: computer audio interface - alternative to 3.5mm

I've had excellent luck with Digigram UAX220 series USB sound cards. I have many of them throughout my facility on Intel NUCs, several in daily on-air use. https://www.digigram.com/sound-cards/uax220v2-stereo-usb-sound-card/ There is also a version with a mic preamp built in as well, depending on yo...

Re: Starlink LAN

Here is a link to photos of one of my 5.8 links after first installation... https://www.dslreports.com/forum/r30059401-12-mile-Ubiquiti-shot-in-a-major-metro Site has changed quite a bit since then (including a few cable ties... lol) but the 5-5.8ghz link remains stable.

Re: Starlink LAN

You will get much better results for less cost and effort by going to a higher frequency. 5.8 gig unlicensed or if licensed, 6 or 11 gig. You can easily get 50 to 100 gig throughput. The unlicensed stuff is a few hundred dollars. There is no point in putting good money into 950 Meg gear. True... an...

Re: Starlink LAN

I'm temporarily passing an AES feed over that exact scenario (900 on 950 dishes) on the same link I spoke of before... using Moseley Rincons... because I can repurpose them later once the Starlinks come back... that's Moseley's proper config for IP... but of course it's their product. 900mhz is not ...

Re: Starlink LAN

Going through a project with them right now actually using that function/port. I assume you're talking about 950mhz boxes... not T1 which are inherently bi-directional. I can't speak to a Barix box, although I don't see why it wouldn't work with some form of UTP, but I CAN tell you if your StarLink ...

Re: Ideas for creating a stream from multiple stations?

Thanks Shane, Spot replacement is a little out of the scope of the project at the moment, although I'd have a super awesome mess to deal with if they wanted that to happen. I'm almost positive that in order for this to remain on the up-and-up that it would be a direct simulcast (spots included) for ...

Ideas for creating a stream from multiple stations?

So here's a new curve ball I haven't heard of someone dealing with yet... One of my stations in Phoenix has begun syndication on our afternoon show as a night show for client stations. We are currently in 4 additional markets, and we're looking at hitting 10 or more before the end of the year. The h...

Re: Lower cost portable spectrum analyzer

I recently bought one of these https://smile.amazon.com/dp/B00XZYPPZ8/ref=cm_sw_r_cp_ep_dp_3A-iyb6JCWBSR for a project I was working on, and I highly recommend it if it fits your needs. It definitely works stand alone, although the resolution of the data isn't awesome on the screen unless your looki...

Manuals for Potomac AG-51/AA-51?

Hi guys, I've inherited an AG-51 and an AA-51 in great shape (cosmetically, at least) that came from the former Scottsdale facility of a certain processing manufacturer that's recently changed ownership. I even have some of the transformers to go with them, but the biggest problem I'm having is trac...

Re: Calculate approximate ERP from field strength at known distance

No, they filed a complaint with the FCC. I have responded to their complaint the old fashioned way by resolving all listener complaints however, but I just was trying to do further research in case if they attempt to continue fighting.

Re: Calculate approximate ERP from field strength at known distance

Thank you all for your opinions and experience. We do have legal council working with us, and I've been working to rectify complaints the old fashioned way as well. I'm just trying to poke as many holes as possible.
