How are you tuning (dragging, scroll wheel, VFO controller) and is it dependent on the rate of changing the frequency.
Also, does it happen when the Spur Reduction is on and/or off? -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jerry Sharp Sent: Sunday, October 05, 2008 9:56 PM To: FlexRadio Subject: [Flexradio] Rx Drops Out While Tuning. 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.
