I agree 23 kbps is a waste of time... AAC+ really shines around 32 kbps and
It would sound a lot better at PL 2 @ 27.8 kbps or even PL 3 @ 30.8 kbps if
they could afford to drop the protection level that much. Surely it
wouldn't hurt for them to test these increased bitrates to see if the
reception drops off much?
Increasing the PL-value means that you need to increase the power to
compensate for the lower protection.
If you know that 90 % of the cost of a MW or LW-station is directly
related to the cost of broadcasting (i.e. the electricity bill), you're
better prepared for a rough ride on the next meeting with the management
of the radio-station.
If that is the case then the cost of the 'talent' must be very low, an ideal 100% efficient 1kW transmitter would cost about 10p/hr to power, of course they are not 100%, but a lot of local MW stations are around 1kW and about 80%; there are other electricity costs in addition to the transmitter, but these are not simply proportional to it. A larger broadcaster will have more studio etc. expense, but should be able to negotiate lower rates for electricity.
In simple terms; do you really think that my local 1kw MW station is paying 1p/hr for staff, rent, rates, heating, programmes, etc.?
In truth it costs broadcasters thousands of pounds per hour, and because of this we could not persuade many to scrap working equipment and replace it with more efficient transmitters to save 1p/hr.
There are always two people in every picture: the photographer and the viewer.
