[hpsdr] Re Ozy Problem

[Geoff]

Hi Guys,
	Last night I dug out my spare Ozy. It has the C7N part. A quick and 
dirty "smoke test" shows it working OK at 96000/2048. A quick try at 192000 
was not sucessful (very choppy audio). I left the system listening to the IBP 
beacons on 20m overnight with no problems. I haven't heard the chattering 
relay problem with either Ozy and the upgrade to the latest firmware on 
Mercury and Penny went smoothly.
	I have a "C7" Ozy, a "C8" Ozy, Mercury, Penny, a Kubuntu/XP laptop and an XP 
desktop box. If anyone has any suggestions with respect to a detailed test 
procedure I am willing to put some time into it. I have a 3 day weekend so 
time won't be a problem.
