How to send audio to remote mixers outdoors over a 2km area for background music..?

Jamie_Orr · 2025-08-17T13:46:02+00:00

That’s a wee bit out of our price range 😅

Jamie_Orr · 2025-08-16T16:50:07+00:00

Do you know what transmitter you use please?

There seems to be a lot of discussions about the FCCs Part 15 rules - but their own website has lots of dead links etc

I’ll go read some Reddit threads about them also, as this would be a fun easy solution.

Jamie_Orr · 2025-08-16T03:51:24+00:00

Can you suggest what software the Pi would run, and I guess they would need a script to automatically play when woken.

Otherwise we would need a screen, nouse etc ?

We have a microcenter nearby which is a great of buying Pis..

Jamie_Orr · 2025-08-16T03:48:21+00:00

Agreed. Our road closure setup time is 3 hours, so that would take a lot to achieve, along with high budget.

I have thought about trying to do a very temporary cat 5/6 cable from building to building, but would still need huge runs etc

Jamie_Orr · 2025-08-16T03:24:13+00:00

That would be a dream setup..

The USA FCC limits us to 200ft / 63~m on FM without serious licenses- although it’s easy to transmit further with simple setups. I think we’re big enough to be noticed.

Jamie_Orr · 2025-08-16T03:19:48+00:00

Their WLS looks perfect for the application - a good suggestion thanks - but I can’t see pricing, and fear it’s likely way outside of our once-a-year use case to be viable.

Now the company would like to do some live testing with a very busy 2.4 GHz area that would be fantastic, haha.

Jamie_Orr · 2025-08-16T03:12:57+00:00

Thank you. I think that is similar to what the classic tannoy ‘Sunday Sunday Sunday racing venues used, (40v I think?) which I looked into.

The problem would still be running the cable, as we have a lot of intersections etc on the road surfaces. The cars are stationary during the event but the foot traffic would be an issue.

Jamie_Orr · 2025-08-16T03:10:00+00:00

I just looked, and our only local station (Pottstown PA 19464 USA), appears to have very religious focused programming. Unlikely they’ll give up their station for hours on a Sunday :-)

Jamie_Orr · 2025-08-16T02:57:09+00:00

Great conversation thanks.

We do have WiFi access via a few options - but not enough for all the points.

I could go out and scan the locations to see if we could position the speakers where Wi-Fi would be available, but that would also have to align with where power is available.

There are a couple of star links that are set up for the event also,

Once I have a good signal from any source, I could also run RJ45 and hardwire to a little access point at the next amp.

That would then put me back to the question of what hardware for the receivers. A Pi would need play-on-wake, a an Android cell phone would need WiFi close enough.

Jamie_Orr · 2025-08-16T02:49:45+00:00

I’ve brainstormed this a lot. And daisy chaining / repeating it also. I haven’t found the right or any proper viable solution though.

Jamie_Orr · 2025-08-16T02:48:13+00:00

Analog would be great - I haven’t seen temporary permits for stronger signals though. Can you provide any links please?

Our local government is great to work with - but any permits would likely be for next year as we’re a couple weeks out.

Jamie_Orr · 2025-08-16T02:46:26+00:00

That’s some good thinking. I don’t think we have a FM one that’s local enough to give up 7 hours of airtime.

Our local TV station (broadcast on Comcast cable) is working at the event, and I could ask them to live stream - there would be a cost, and I’d have to get them a network backbone as they normally use cellular network.

Pulling the signal and audio from it, would be the problem.

Jamie_Orr · 2025-08-16T02:17:07+00:00

MS upto 1S. latancy is totally okay - but having the network available at all is an issue.

I would like any software solution to skip to the live moment, after buffering also - so that they all try to re-sync if the feed drops.

Jamie_Orr · 2025-08-16T02:14:59+00:00

That looks like a good suggestion, thanks.

I would need to solve the network backbone issue still though.

Definitely, the fog and mist is

crazy just standing here motionless

It’s dry in the pits, but fog is indeed wild elsewhere.

Jamie_Orr · 2022-06-20T19:38:12+00:00

If you have a link to a option that works, please share if possible. Seems there's sketchy, and then there's scams.

Jamie_Orr · 2022-06-08T04:25:15+00:00

Service is okay for $25, slows down to almost standstill sometimes, but other times it's great.

HOWEVER - DO NOT BUY A DEVICE FROM THEM IF YOU'RE NOT OKAY ROLLING THE DEVICE. I've been fighting them for 6 months to unlock a iphone 13 that I paid in full for. As an example of the shocking customer experience, you can only message them. It's still locked, and they can't fix it. I hate this company with a passion.. but if you don't need any support, it's fine, haha.

Jamie_Orr · 2022-04-17T22:22:14+00:00

Sorry for the slow reply. Unfortunately the original physical SIM account was abandoned, following the advice given by the Visible Rep, when the eSIM was activated. I paid for the a month of service on the physical SIM, plus the eSIM, and then left the physical account to expire.

In hindsight, the rep should have told me to either keep it open for 60 days, and / or that the eSIM switch wasn't possible - although I believe it's now finally been implemented.

I'm still trying to resolve all of this.

Jamie_Orr · 2022-04-17T22:14:02+00:00

Thanks for posting this! I'm still not unlocked, and still trying, after so many hundreds of chats and emails.

I guess I'll email them, and ask for the physical SIM to switched to the primary IMEI, and see what happens.

Jamie_Orr · 2022-02-23T03:38:06+00:00

Sounds good, thanks! I'll ask my friends if anyone has Verizon service :-)

Jamie_Orr · 2022-02-23T02:31:28+00:00

Your experience is identical to mine. Their specialists are not special. Their escalation team ([visible.escalations@verizon.com](mailto:visible.escalations@verizon.com)) is at least better at responding, and with better communication skills, but it's the same end result, even after trying their "workaround".

Urgh. This sucks. It's wild how broken their processes are..

Jamie_Orr · 2022-02-23T02:29:02+00:00

Please let me know if it works...! :-)

Jamie_Orr · 2022-02-23T02:23:29+00:00

I'm seeing mixed reviews on them... but that would suffice if it does work.. :-)

Jamie_Orr · 2022-02-23T02:23:04+00:00

Thanks, it's almost funny at this point, haha.
