Thanks, Simon! It makes sense that if the "native" speed is 48K, any other speed would require some type of "conversion".
One more question, if I can impose on your good nature! What impact, if any, does the error in sampling rate have on any TX/RX offset? During the Tara Rumble I noticed that almost every station that responded to my CQ, came back a bit lower in frequency than mine. One station I responded to even told me I was off- frequency. I don't believe my IC-746 has any offset, and my RIT/XIT was off. Does that large error rate of 6984 ppm create an offset, and can I determine how great it is?
