Does anybody out there know approximately what frequencies the older 0-100 tuning scale correspond to? Sure- I could divide the broadcast range in half, and put 50 at that frequency, but It would be nice to know where some modern stations would fall on this scale. Any ideas from old station programming guides or service manuals?

Hi Warren

Radios with 0-100 on the dial generally were not linear. The zero was the highest frequency which usually represents around 1500 on the band. Some of the early radios do not even tune this high. The 100 reading was around 550. A station at 900 usually read around 30 on the 0-100 scale. Most of the modern stations will be found crowded between 0-30.

The 0-100 loging scale was often used on vernier dials because it could be used both on antenna tuning capacitators and on detector tuned circuits . The biggest problems is that some variable capacitators are linear in capacity with respect to rotation, while others are wavelength linear and still others are frequency linear (that is stations 10 khz apart are evenly spaced across the dial)
