The start of the next sentence has been incorporated in the link. Just remove the "So" at the end.... works fine.

The link gives an error, but I have no doubt that the meaning of the term varies a bit.
Thanks for the reference. I’ll try to get it working from here.

However the similar British device was called a wavemeter "Wavemeter Class D" http://www.vmarsmanuals.co.uk/archive/724_Wavemeter_Class_D_No2_Working_Instructions.pdfSo here in the UK the 221 was often also called a wavemeter. Classic wavemeters were also available for example the Marconi TF975.
