You're most likely getting the 22m SW signal rectified at the product detector.
If using a tuner doesn't help, you could try a 1/4 wave stub tuned to the
offending frequency; connect it in parallel with your feedline using a "T"
adapter.  It should be wide enough to knock down the other signals in the band
as well.

Given that the Century 21 is a DC receiver,
is it common to hear strong out of band
signals that are not affected by tuning?
Here's what I have. On 20 meters I am hearing
a strong SWBC signal at all points on the 20 meter
band. Using another receiver I have identified the
signal as a very strong S9 +10dB SWBC on 13.640mHz. I
have also heard other similiar strong signals on
various 13.6xx mHz frequencies in the same way.
Is this an example of the common "blowby" problem in
the DC type of receivers ?

Thanks for any info.
