Fresh Software - 20050917 level
- I've posted a few updates to the SoftRock updates for PowerSDR. Nothing
major, just some bug fixes. Specifically:
- Fixed problem using an SDR 1000 in fixed freq mode
- Fixed a potential glitch/hang in level calibration with a SoftRock 40
- Fixed smooth panadapter scrolling when in fixed freq mode

When I operate on the low bands (40M thru 160M) I have to turn off my
PC's. In fact I sometimes have had to unplug them completely, as the
power supply isn't completely off when the On/Off switch is in the Off
I found the problem to be caused by the computer's switching power
supply. In fact I lost a power supply in one of my computers recenly,
and replaced it with a better grade supply, and then was happy to find
that the noise from that computer was gone.
Try unplugging your computer completely and see if that quiets things
