Jerry,
I have to agree with Tim, could be the motherboard parallel port..
Early on with the 1K it was discovered that not all parallel port are
considered equal. Some do not drive hard enough, also you have to be
careful with the cable lengths and type of cable used..

Fellow Flexers, my SDR-1000 or computer has developed a problem and I
could use some suggestions. As I tune across any part of the spectrum,
I hear a relay click from the SDR1K and my receive drops very low. The
display on the panadapter usually drops out of sight on the bottom and
signals become very, very weak. The drop-out points seem to be random,
sometimes I only have to tune 5 KHz, sometimes 200 KHz.
Turning PowerSDR off and back on cures the problem...until I start
tuning again. I've deleted the PowerSDR.mdb file several times and
have tried several different versions of PowerSDR to no joy. I've
also checked all my cables and connections and they seem fine.
One change I've made on this end is a new motherboard and
processor...a Gigabyte GA-73PVM-S2 motherboard and a Pentium quad core
processor. The motherboard has an on board parallel port to which the
SDR is connected.
At first the SDR1K seemed fine with the new computer hardware, then
the problem started. I've played with some of the parallel port
settings within Windows with no luck. BTW, I'm running XP Professional
with service pack 3 installed. I also could not find any articles in
the Knowledge Base pointing to a problem like this.
Any ideas would be helpful at this point.
Thanks and 73,
Jerry Sharp, KD0GS
