The only station I know of from Europe that does a DRM broadcast
beamed to America is Vatican Radio from 2300UT-2330UT on 9755kHz. It
is FM quality and stays locked in under good conditions with only a
few momentary distortions.

Is that from Europe? Or is it a relay from Radio Canada's site?

There is a listed relay broadcast earlier on 9800 kHz at 1945-2030UT
from Vatican via Canada. This was not monitored.

Here is the signal and transmitted information from the DRM Vatican
broadcast on 9755 at 2300UT and the earlier DRM Radio Canada broadcast
on 9800kHz.

Radio Canada on 9800kHz @ 2100UT - DRM signal S9+25dB
Info: 17.16 kBits/sec / EEP AAC+ Mono / CA
Message box: From Sackville, NB Canada for your listening pleasure
Audio: No dropouts. A few quick intermittent distortions.

Vatican Radio on 9755kHz @ 2300UT - DRM signal s9+20dB
Info: 14.56 kBits/sec / EEP AAC+ Mono / VA
Message box: We are sending a DRM transmission on SW 9755kHz for North
America from Vatican Radio Santa Maria di Galeria-Vatican City
Audio: Periodic dropouts. Multiple intermittent distortions.

Appears the broadcast comes from Europe but can't guarantee it. Will
check the relay broadcast tomorrow if I can.

Vatican relay broadcast from Canada
9800UT @2000UT DRM signal S9+15dB
Info: 17.40 kBits/sec / EEP AAC+ Mono / VA
Message box: blank
Audio: No dropouts. Very few intermittent distortions.

So, it appears there is no way to prove where a DRM signal comes from.
The info area shows the Vatican (VA) as the source but there is no
indication it is relayed by Sackville other than signal quality.
