Trying to get a clearer signal by listening in LSB mode, I have noticed
that the LSB signal is apparently absent (or considerably reduced). USB is
OK. Does someone know if indeed Vatican Radio transmits in a carrier + USB
mode on this frequency ? If so, why ? (it seems more logical to take a
carrier + LSB mode to avoid interference from 531).

True, it would be better as far as interference is concerned. Actually they
are on 526.5 (at least they were there last time I checked), which is the
lower limit of the mediumwave band. (The lower "official" channel being
531, 4.5 kHz for each SB makes 526.5 the lower limit of the band.)

If they used LSB, the side band would be outside the BC band.

Also they do not worry too much about inferference from Switzerland 531
kHz, since the Vatican station is only meant for local coverage and locally
they are far stronger than the Beromunster station.
