I will try to play around with the > 125 MHz clock of the AD9850, so let's see what I come up with. I'm switching my 4MHz LXO by a very small fast 10V relay, driven directly (!) from the TXD output of the RS232 of my old i386 notebook. 45.45 baud is no problem, it works fine up to approx. 75 baud. I'm using the "opening" relay contact. It works fine at RTS or DTR too. Of course it has to be a *very* low power one... Using opto-coupling devices there I was not able to get a clean signal. 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
