1935 Philco 144

Scott

There were some military/govt coastal /maritime stations that worked at frequencies close to the IF, so the wavetraps attenuated the signal from those stations.
These stations no longer are in service so there is nothing to protect from. So a bad wavetrap can be simply removed with no ill effects today.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
