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
