AI INFORATION:

The TR.1366 was a British airborne HF radio transmitter/receiver (transceiver) developed during the Second World War for the Royal Air Force. It was manufactured by Standard Telephones & Cables (STC) and formed part of the Airborne Radio Installation (ARI) 5206.

Main specifications

• Designation: TR.1366
• Manufacturer: Standard Telephones & Cables (STC)
• Type: Aircraft HF R/T (Radiotelephone) transceiver
• Frequency range: 18–20 MHz
• Service: Royal Air Force
• Period: Introduced during the latter part of WWII (around 1944–45).

Purpose

Unlike earlier RAF aircraft radios that were primarily Morse (W/T), the TR.1366 was designed for voice communication (R/T) over the HF band. It allowed:

• Air-to-ground voice communication.
• Air-to-air communication over longer distances than VHF when atmospheric conditions permitted.
• Operation as part of the ARI.5206 installation.

Development

The TR.1366 was later developed into the:

• TR.1462 – described in RAF equipment lists as the HF version of the TR.1366, also produced by STC as the 30-LE-24B and used in the ARI.5206 family.

Documentation

RAF servicing publications list:

• A.P. 2538 – Airborne R/T, 18–20 Mc/s.
• A.P. 2538 JB – Instructions for testing and aligning the TR.1366 using Test Kit Type 7.

Physical characteristics

The equipment consisted of:

• A compact aircraft-mounted transceiver unit.
• Separate control box mounted in the cockpit.
• Remote tuning and aircraft power supply (typically 24 V DC).
• Connection to a trailing-wire or fixed HF aerial depending on the aircraft installation.

Because relatively few were produced compared with famous RAF sets such as the TR.9D, TR.1133 or TR.1143, surviving examples of the TR.1366 are uncommon today.
