Appendix 1
Intermediate frequencies
This list covers models going back to the first commercial superhets and has been submitted, where possible, to the makers for checking. Frequencles thus: 465, 473, are alternatives, but 123–127 indicates the circuits should be staggered over the band indicated. Sometimes the frequencies for each circuit in a ‘staggered’ set are shown thus: 127–123–123–127.
