Re: [Flexradio] Rx Drops Out While Tuning.
Thanks all for your suggestions. The problem seems to be pretty much resolved as long as Spur Reduction is turned on. I don't have any extra PCI slots..this MB came with 2 PCI slots and 1 PCI Express slot..all three are filled with cards I need to have. And no, I'm not going to spend $80+ for an overpriced specialized USB to parallel adapter. :) All is good again.

[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.

Re: [Flexradio] Rx Drops Out While Tuning.
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.

Re: [Flexradio] Rx Drops Out While Tuning.
Tim, ah ha, I turned Spur Reduction back on the the problem appears to be mostly gone! But it still drops out once in awhile when I'm tuning fast. Much better though...

Re: [Flexradio] Rx Drops Out While Tuning.
Turning on SR minimizes the number of control signals sent over the parallel cable to the DDS when tuning. Having SR on should be the default configuration used by every radio type. The problem may still be in the parallel interface or the cable itself. Some mobo parallel interfaces may not have the full 5 VDC or is sharing interrupts with a dozen other interfaces and that can cause a problem. You can get a cheap parallel port interface card that goes in the PCI bus for almost next to nothing to try if it keeps on happening. -Tim -Original Message- From: Jerry Sharp [mailto:[EMAIL PROTECTED] Sent: Sunday, October 05, 2008 10:14 PM To: Tim Ellison Cc: FlexRadio Subject: Re: [Flexradio] Rx Drops Out While Tuning.

Re: [Flexradio] Rx Drops Out While Tuning.
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.. 73, Dudley WA5QPZ Jerry Sharp wrote: Fellow Flexers, my SDR-1000 or computer has developed a problem and I could use some suggestions.
