These units were generally ground based, being often associated with search light radar. The "RDF" refers to radio direction finding, a title often used to hide the real use of the equipment.
The units had wide band receivers and although hundreds of units were released after the war, they were not very useful. A few brave souls used them on 2 metres - they were great until more than one signal appeared on the band. All signals tended to mix together. Most were wrecked for parts - even then there was not much of use in them.
The RDF No1 comes with a built in power supply - but this was designed for 80 volts at 2000 cycles.
