Wireless Temple Audio Broadcast -- 2

Budget: ₹1500 - ₹12500

I need a complete, practical system that carries live chanting and prayers from our temple and plays them through a roadside speaker roughly 5 km away. The audio only has to be standard-quality speech and music, but it must stay clear, continuous, and sync correctly with the live feed in the sanctum.

Your job is to specify, price, and integrate everything—transmitter, receiver, antenna choice, power amp, weather-proof speaker, control electronics, plus the small software layer that captures the temple microphone signal and pushes it over the air. Any off-the-shelf modules are fine, yet I still want a clean bill of materials showing individual hardware costs and a separate line for your development time so the trustees can approve the budget.

Key requirements • Live audio, no noticeable delay, reliable coverage across 3–5 km of mixed terrain and occasional traffic noise. • Installation must respect local spectrum rules; if a licence-free band is used, note compliance limits. • Simple operator workflow: power-on, press play, and the system streams until switched off; optional remote monitoring or auto-reconnect is a plus.

Deliverables

1. Schematics and wiring diagram.
2. Itemised parts list with current market prices.
3. Firmware / software (source code) with build and deployment instructions.
4. Step-by-step installation and tuning guide.
5. Final cost summary: hardware subtotal, your software/service fee, and any optional add-ons.

I will test the setup on-site; acceptance is granted once the broadcast is clearly audible to highway travellers during normal daytime conditions.

System to be developed using voip on internet. Two locations ( multiple site delivery speakers desirable not essential)
