With Alpha versions up to AQ, both Linux and Windows XP, the position on the waterfall (in PSK250 mode) stills wander up and down by several hundred Hz despite my settings to keep within 20 Hz (General and Mail) . Particularly in the presence of a nearby signal, any mode. In an older version 3.12 that came with my Puppy of PSKMAIL Server, it did not do this, rock solid on 1000 Hz. I have not installed AR yet
