Racal TRA-921,

also called Racal Syncal, is a solid state portable HF radio, built in the UK.

It is one of the many radios that Racal built between the 60s and the 80s for military and paramilitary purposes. It was used by armies throughout the world.

Frequency is switched by decade switches, an ATU is built in.

The GDR used this radio to develop their mobile and portable HF radios like SEG-15 and SEG-100. So, for example, the antenna bases of the TRA-921 and the SEG-15 are identical.

Connectors for handsets
