You are experiencing overload to the detector in the Century 21 from a
nearby BC station. I suggest you listen to the station ID and then look up
the frequency on the internet and then install a series inductor and
variable capacitor resonate at the offending stations frequency from the
center conductor of the coax to ground and tune the capacitor until the
unwanted signal is attenuated. You can connect this device by using a
T-connector the one port to the radio, one port to the antenna and the
remaining port connected to the series LC circuit between center conductor
and ground.

Subject: [TenTec] Century 21 Analog Question...
Hello:
I have an old Century 21 (analog dial) which seems to be suffering from
overload
on 40 meters; some SWBC station (apparently a domestic English language
religious station) is very clearly heard as you tune across the entire 40
meter band... with the CW and SSB signals also appearing as you happen
across them.
The rig appears to operate fine (with no SWBC blasting through) on 15
meters; I was astonished to work an F6 near Limoges on the first call...
Any comments, on list or e-mail, would certainly be appreciated.
73,
