The Delta 44 (and the Audiophile 192) do not have a microphone input to switch in instead of the line input. Both cards have just the line input (2 or 4 channels). So there is nothing to switch inside the card, except possibly the gain, but I would be much surprized if a gain change would take so long to prevent a reasonable Rx/Tx switching time. > > Sound cards were not designed to be re-configured very often so they > have skimped in that area, after all a typical use is to set it a > certain way and it remains that way. > This is true, but before saying that a 4x4 card is a must, I think that a bit of investigation on the time needed to do a gain change should be performed. Unless the guys at Flexradio have already measured it, in which case it would be interesting to know the results. 73 Alberto I2PHD ------------------------ Yahoo!
