HNY Phil,
While I'm not an attorney, I've read the rules (subject to
interpretation of course). Transmission of music is specifically
unlawful. (What is defined as music these days, also subject to
interpretation, hi hi.)
Defined in the simplest of terms, any sound transmitted other than for
the purposes of communication (voice, tones for digital) is illegal.
This includes background music in the same room as the microphone
(though generally ignored as part of the environment, in the US; same as
telephone 'hold' music in an autopatch; traffic noise etc.) and
certainly includes the 'musical' sounds from most OS (they offer no
communication).
Which, to me, means the sounds from an OS are unlawful to transmit. If
the incidental OS sound is spoken ("You have mail"), that isn't legal in
the digital, non-phone) portions of the bands. At the very least, they
use more spectrum than necessary (i.e. 3 KHz bandwidth in an area for
FT8, which uses ~60 Hz bandwidth per user) and offer nothing for
communication.
Considering the general apathy of the FCC lately (US of course), I'm not
surprised that this has never been tested by citation. I'd much rather
err on the side of caution. Turning off the OS sounds is not a complete
solution.
Using a sound card, specific and limited to the radio use, is a vast
improvement over using the OS sounds device to maintain legality.

A generically 'bad' idea and is the reason that voice, operating

portions of the bands.
Please explain your comment "all illegal" concerning "operating system
sounds". As both a telecommunications engineer and a communications
attorney I have never had to deal with the legality or illegality of
"operating system sounds".
