Re: [AFMUG] STL license frequencies

I tried to do nlos stl on 950. Didn’t work at all. It needed a very strong experience signal for full quieting. Sent from my iPhone > On Feb 13, 2019, at 5:51 AM, Lewis Bergman wrote: > > They are more likely to want a camera pointing at their transmitter rack. > Most of them don't have as mu

Re: [AFMUG] STL license frequencies

They are more likely to want a camera pointing at their transmitter rack. Most of them don't have as much monitoring as you would think. We had a few on our network. They used our ethernet as primary and a sat backup. Only the large market stations have engineers that know anything. The rest contac

Barix does coordination, application etc. They also have ip equipment  for forward and store or lost link(s) between studio and tower. https://www.barix.com/ https://www.barix.com/downloads/downloads-software/studio-transmitter-link-stl-application/ On Tuesday, February 12, 2019 Tim Hardy wr

Re: [AFMUG] STL license frequencies

Comrex Briclinc will do wonders at transporting the audio over an IP STL. Otherwise for analog audio only the 900mhz band as discussed is where you’ll be. Should be able to go through foliage. Mountain. Not so much. > On Feb 13, 2019, at 12:08 AM, Daniel White wrote: > > Sure. But consideri

Re: [AFMUG] STL license frequencies

Sure.  But considering it would be a new link more bandwidth opens new opportunities like maybe they want a video camera up there for security. If its NLOS though, yeah 950MHz is going to be a better bet. Daniel White Co-Founder - Business De

Re: [AFMUG] STL license frequencies

Yeah, I've seen that done. One guy had some boxes he got from Holland, I was stunned that they didn't have a jitter buffer.  It seemed to me since the transmission is one way that it would be harmless to have a 5 or even 10 second buffer and have plenty of time to retransmit any lost bits.  Se

Re: [AFMUG] STL license frequencies

we have a lot of radio stations on our network and they just feed their transmitters of our IP network. -sean On Tue, Feb 12, 2019 at 6:14 PM Adam Moffett wrote: > I'm trying to help out a local radio station. I've never dealt with > this before, but aren't there licensed frequencies that a r

Re: [AFMUG] STL license frequencies

The STL gear that I've seen is small-channel audio-only data, something like unidirectional 128kbit with a high-quality audio codec. If you need to find out equipement manufacturers I can look up pictures taken inside of sites where I saw STL devices in use. Based on it being higher-power 900mhz b

Re: [AFMUG] STL license frequencies

I wonder how much bandwidth an STL really needs. We can do 11ghz in two hops, but the single hop path is NLOS. On 2/12/2019 8:57 PM, Daniel White wrote: Adam, There isn't a lot of spectrum on those channels, so your only going to get 3Mbps or something like that. I'd probably put up someth

Re: [AFMUG] STL license frequencies

Adam, There isn't a lot of spectrum on those channels, so your only going to get 3Mbps or something like that. I'd probably put up something like an AF-11 instead if your on a budget. Jeff Holdenrid over at DoubleRadius has done a lot of work with both radio and TV STL links.  I did a few pr
