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 ..
