Wireless Set No. 17 Wavemeter Mk.II. ZA 171133.
Because the tuning scale of a No. 17 Set was not calibrated in frequency, an absorption
type wavemeter was supplied for use at a Control Station. The wavemeter fitted on
its side with the wooden projection facing into the back compartment of the set near
the RF coil. In the SEND position, the transceiver dial was tuned until maximum glow
was observed in the wavemeter lamp
