Everyone
Something to consider also is that when the R390 was developed, the
mechanical filter development project(s) Collins was not yet complete. The
use of L/C networks for selectivity was the current approach during the R390
development. Had the mechanical filter project(s) been complete, the R390
would have had them from the beginning.
