Band 2 : - 4.0 to 12.0 Mc/s.

Both these bands are directly calibrated on a very good slow-motion dial.

An internal speaker is fitted and can be switched out when headphones are being used.

The receiver has a BFO for CW reception and also a crash-noise limiter of the simple type.

A panel socket for a plug-in lamp is provided for use when working in the dark.
 

Power Supply
The power supplies are incorporated in the receiver which is designed to run from a 6 volt accumulator, it therefore has a vibrator HT pack giving a well smoothed  and filtered 150 volt HT.

With a 6 volt battery supply the load is 2 amps.
