But it does great with 96kHz ASIO or 48KHz ASIO which I have > tested. Alberto does not have any EMU products but I have two. I own the 1820m and also the 1616m. Both work extremely well with ASIO and winrad but the EMU setup was not easy. I understand that Creative/Emu have made some changes to their cheaper products. Mine, for example, do not need any sample delay. Which reminds me, sample delay is not ever needed for ASIO; it is only needed for WMME. Another thing we have heard about Emu is that they are using ASIO channel assignments other than #1 and #2 for their new cheaper products so it is likely that this is what you are experiencing. Alberto will be adding full ASIO channel selection in the next release so that will take care of that problem. It is not a problem of the DLL support that the channel skew calibration only works perfectly at one offset frequency. This is a true statement about the softrock, the Flex1000, and all soundcards no matter now good they are. The calibration of this is supposedly done by "Rocky" software but I have never been able to see it work properly. Linrad also can be calibrated using a pulse source applied to the receiver inputs. Linrad will typically create an image rejection of around 60dB across the entire displayed band. When manually adjusting the calibration controls in Winrad while using the better Emu cards, I see a spot image rejection of 115dB and it is still better than 60dB over a modest offset range. The full band calibration will be incorporated into a future version of Winrad but it is obviously dependent on the hardware so Alberto is waiting for me to design that. 73, Jeffrey Pawlan WA6KBL _______________________________________________ Winrad mailing list [email protected] http://winrad.org/mailman/listinfo/winrad_winrad.org
