Back in February I was trying to sort out modes settings and received
some detailed advice from SquarePenguin on possible radio mode settings
that would achieve my objective of recording classical music (from
radio3) at the best resolution but having spoken word at a lower
resolution when recording with pvr.
In short the solution was to leave the "classical Music" pvr list items
to use the default radio (best) setting but add the line:-
radiomode = good
to the pvr items for spoken word.
Time flies and I confess I have only just tried this, prompted by
extravagant disk usage where typical programmes jumped from 30-40 MiB to
90-100 MiB.
The result achieved the desired saving, in this case from 99.6 MiB to
30.0 MiB but my Linn player will not play the file. A sense of deja vu
here as I had similar problems back in January.

Both files check out with AtomicParsley and both play with software
players so it looks like a repeat of the Linn problem even though I am
using their older firmware which solved my "long file" problem.
Will now try radiomode = better and radiomode = worse but if anybody has
any other suggestions please let me know.
