Historical Radio Telegraph

Build your station. Tune your frequency. Send your message.

Historical Radio Telegraph brings the fascinating world of 1930s–1940s radio communication to Minecraft!

Experience authentic Morse code communication, construct functional radio stations, and establish your own telecommunications network using antennas, transmitters, receivers, and electrical equipment.

This isn’t just another communication mod. Every signal matters, every connection counts, and building a reliable radio station requires proper infrastructure.

How to Use

1. Power your first station

Place a Radio Telegraph Station near the spot where you want your antenna. Connect a Field Radio Generator to one side of the station using at least one Power Cable. The blocks must touch face to face.

Field Radio Generator → Power Cable → Radio Telegraph Station

Right-click the generator with coal to insert fuel. Then right-click it with an empty hand and press START / STOP GENERATOR. You can also connect a Radio Battery Bank to the same cable network. A newly placed battery starts empty and charges while the generator runs.

2. Build a 7 MHz dipole antenna

Find a clear stretch of level ground. Build three Antenna Mast towers in a straight line, each five mast blocks tall. Place the outer towers 10 blocks from the center tower, measured from the center of one mast to the center of the next. For example, use X coordinates 0, 10, and 20, keeping Z the same.

Place an Antenna Feed Point on top of the center mast.
Place an Antenna Insulator on top of each outer mast.
Right-click the feed point with an empty hand. Its panel should read Half-wave dipole. If it reads Quarter-wave vertical, press SWITCH DIPOLE / VERTICAL.

3. Connect the two antenna arms

Use the Antenna Wire Spool to make two separate connections. The center feed point is an endpoint for both wires.

Right-click the center feed point, then the left insulator. Look for Connected 10.00 m.
Right-click the center feed point again, then the right insulator. Look for the same confirmation.

Left insulator ← 10 m of wire → Center feed point ← 10 m of wire → Right insulator

Keep both wire paths clear. If you connect the wrong blocks, hold the spool and Shift + right-click an endpoint to remove its connections. Clicking an outer insulator lets you redo just that arm.

4. Connect the antenna and tune the radio

Run Coaxial Cable from another face of the radio up to the center Antenna Feed Point. Each cable block must touch the next face to face, and the last one must touch the feed point. The mast supports the antenna; the coax carries the radio signal.

Open the radio, switch POWER on, enter 7000.0 in FREQ. (kHz), and press SET. Open [i] to check the station measurements. For this build, look for an antenna Length of 20 m, an Input SWR of 3:1 or lower, and TRANSMITTER READY.

5. Make your first contact

Have another player operate a second powered station with its own antenna in the same dimension. Set both radios to 7000.0 kHz and open both station panels.

For a quick test, send the letter A. Tap SPACE briefly for a dot, pause briefly, then hold SPACE about three times longer for a dash. You can also hold the on-screen MORSE KEY with the mouse. Ask the other operator to listen for the short tone followed by the long tone, then send it back. Once you hear the reply, you have confirmed that both stations can transmit and receive.

If the station shows a warning

Station message	What to check
OPEN OR INVALID ANTENNA ARMS	Select Half-wave dipole. Check that each outer insulator has its own wire to the center feed point. A single wire stretched between the outer towers skips the feed point.
ANTENNA MISMATCH — POWER REDUCED	Open [i] and read Input SWR. For the 7000.0 kHz example, check for two 10 m arms and 20 m total length. For a custom build, an optional Antenna Tuning Unit in the feed line lets you adjust inductance and capacitance while watching the SWR reading.
NO ANTENNA CONNECTED or NO RF FEED LINE	Follow the coax from the radio all the way to the feed point. Check for gaps, diagonal connections, or a cable that ends at the mast.
BATTERY EMPTY / GENERATOR STOPPED	Add fuel, start the generator, and check that a Power Cable connects it to the station.
