VoxHF

Your IVAO communications, wherever you need them.

A local-first browser console for radio, live voice, transponder controls, weather and network messages. Altitude stays on the simulator PC while the controls follow you to another screen.

Core controls

The essentials stay together.

Radio and transponder

Tune one active frequency on COM1 or COM2, transmit, and control squawk, STBY/ALT and IDENT.

One focused workspace

Keep messages, nearby stations, route weather and the controls used during a live flight together.

Local control, remote reach

Keep the IVAO connection on your simulator PC and choose whether the browser stays local or uses your relay.

Inside VoxHF

One workspace. Four focused jobs.

Each view is reserved for one core workflow, so the final screenshots can show the product clearly instead of shrinking the entire interface into every frame.

01 / Radio and XPDR

Control the active radio and transponder.

Tune COM1 or COM2, choose nearby stations, and manage squawk, STBY/ALT and IDENT from the same panel.

02 / Live voice

Use the microphone you already have.

Listen to RX on multiple trusted devices and transmit from the browser, including with a phone as the cockpit microphone.

03 / Network messages

Keep every conversation in its place.

Send commands with autocomplete and separate frequency traffic from private controller or pilot conversations.

04 / Route weather

Read weather without decoding it twice.

Request route METAR and TAF reports, then expand them into a clearer interpretation when the raw report is not enough.

How it works

Altitude stays on the simulator. VoxHF meets you in the browser.

01
Run the local agent
It connects to PilotUI, PilotCore, IVAO FSD and the TS2 voice service on the simulator PC.
02
Open a trusted browser
Use the local address, connect to an existing server or point the agent at a relay you host.
03
Keep flying normally
Altitude remains authoritative while VoxHF mirrors state and sends only allowlisted controls.

Local by design

Your IVAO connection stays on your PC.

The browser never connects directly to IVAO. The optional relay only carries authenticated state, commands and live audio between the local agent and trusted browsers.

Choose your setup

One cockpit. Three ways to reach it.

Start locally with no account, connect through a server you trust, or run the complete stack under your control.

Use it locally

No account and no external server. Open VoxHF directly on the simulator PC.

Local setup 02

Connect to a server

Reach your local agent from another trusted device or network through an existing server.

Remote setup 03

Host your own

Operate the webapp, relay, account database and administration tools yourself.

Server setup

Project status

Local and remote COM, XPDR, messaging, weather, browser RX and microphone TX.

In validation

Clean installation, VPS recovery, compatibility checks and broader security review.

Next

Independent review, beta feedback and stabilization toward a release candidate.

Questions

The short version.

Does VoxHF replace Altitude?

No. Altitude and PilotCore retain the IVAO connection. VoxHF adds a browser control and communications surface around them.

Can I use only the local version?

Yes. Local Slim requires no account, relay or public network access.

Can I connect to somebody else's server?

Yes. The operator provides the app address and account access. Review the operator before trusting an independent server.

Does VoxHF store voice or chat?

Default installations relay live audio and messages without recording voice or maintaining persistent full chat history. Independent operators control their own deployments.

Is VoxHF an official IVAO product?

No. VoxHF is independent, unofficial and not affiliated with or endorsed by IVAO.
