941-960mhz
« on: June 12, 2018, 07:49:03 pm »

Shure and Lectro (and probably some other manufacturers) have transmitter/receivers in this frequency band. Anyone tried them? Toured with them? Pros/Cons of working in that frequency range?

I frequently use Shure 944-952 MHz equipment under my BAS-LP license. This past weekend, I had 8ch of IEM and 4ch of mics in X1, which completely filled the band while avoiding four local STL freqs.

The gear works very well, and often times the band is surprisingly clear of primary users (we are secondary on an SBE coordinated, non-interference basis) in otherwise difficult locations such as Manhattan.

However, you must really know what you're doing. You could easily take a major broadcaster off the air if you mess up.  It requires diligent ULS geographic license searches, figuring out geographically where their TX and RX stations are and what that means to you, knowing exactly what their emission designators mean, presenting your freqs to the local SBE coordinator for approval, and being damned careful on gig day.

As far as touring with them, if you're not an NFL GDC or equivalent, or if you're not a nationally recognized expert in the field or assisted by one daily, please don't do it. It wouldn't take many interference incidents for our priveleges in the band to be summarily reverted back to "broadcasters only" rules.

Ok, good info.

So this is frequency band which requires a license to legally operate within the USA?

Are those STL primary use?

Correct. Operation requires a BAS-LP license.

Yes. Studio to Transmitter Link. Most often aural.

That's interesting so your co-channel users are point to point?  Do you actually get the coordinates like a microwave path? 

Can you reuse inside a facility with co-channel users in the parking lot?

That's a lot of liability.

It's almost always fixed PTP paths, rather than mobile remote trucks, but indeed it is a lot of liability. It takes a bit of educated research via ULS to determine the paths, and I personally never attempt co-channel ops. That would be profoundly unwise.

In "the good old days" of common carrier operations we would get very creative with directional arrays to back up to our competitions contours.  We were the scrappy aggressive  local carrier against Pactel.  We would get a license grant a put up a station in what they perceived as their operating contour but was actually right on the edge of the licensed contour. 

As the secondary service clearly your caution is well deserved.

I was unaware of this service, thanks for the detailed explanation.
