I went through the driver control panel and set buffer size to 512 and sampling rate to 48K. Also, set mode to "Normal". This done, I was able to raise one PMBO, but couldn't hold the connection. The receive signal was quite weak, and the PMBO eventually dropped me. Probably I should try another time when propagation is better. I still don't have a good fix on how to set the receive signal for the PTC modem and whether or not the Flex should operate in DIGU or USB. The connection I made was USB, but in DIGU mode, I have to crank up the TX gain to 35 or above to get the drive needed for ALC to be near 0. What is your experience? Gary AI4IN
