Dear Colleagues,

 

I was going through some old files and came across a reference that I hope some members of this august group might be able to help me with. The article made reference to Chart no 19 from the “collection of Wireless World Radio Data Charts.” The chart illustrated was used for determining the bandpass of a variable width IF filter. Does anyone have a copy of this collection of charts or, better, know where it can be found on the web??

 

Any help that could be rendered would be most welcome and please excuse the “off-topic” use of bandwidth.

 

Thnaks and 73,

David Weinreich
