No Graham... it is in your CMOS boot set-up....you should be able to adjust the PCI bus speed, or perhaps the clock divider speed that the bus clock is based on....73...Jordan....

... Er no .. but what to set and what to adjust .?. I assumed the clock was on the sound card .. small xtal oscillator ?

Tnx

Have you tried adjusting the PCI bus settings in CMOS..?

The card is a PCI  ,   M - Audio Delta 4

running with windows  xp-pro

There are a selection of clock speeds .. but  it seems that when a
application runs . it defaults to the 44k setting .. but  for all other
software .. no problem .. works very well

Is this for an on-board sound card, and if not, what type of bus is it
on..?

wspr and the over clocked sound card

Was there a resolve to the problem of the short wspr tx produced by a
soundcard that was running  slightly  faster than it  should

1.5 seconds short .....  about 1 %

, resulting in no decodes for strong signals .. presumably by providing
too many sync's

There is no way of changing the sample rate of the card .. there is a
option in the  driver . but  as soon as wspr  runs . the  card reverts
to
the  normal 44 khz setting

No problems with any of the  other  systems as the  card can be
calibrated
(though not  needed)

any  fixes or ideas ??

tnx

Graham ..
