New Inductor Information

This page describes the construction and measurements on the new inductors used in my SB-101 re-engineering project. All inductors will be varnished on completion of test.

Inductors 1 and 2 below are used in the new five section 8.4 - 8.9MHz bandpass filter used in the shared tunable IF section and shown here on this web site.
