Re: Receive Stutter

Geoff, speaking only about what I see in CPUID, what concerns me is what I'm not seeing. Unless I'm missing something, it looks like you have only one fan and its not identified as a CPU cooling fan. Is that correct? Do you have a CPU cooler? If so please identify the make and model? Is there more t...

Re: Receive Stutter

Try using "F2" to get into BIOS. You have an obvious cooling problem almost certainly associated with your CPU cooling system (check connections to MB). The CPU will throttle down under those conditions. Try installing and running CPUID: http://www.cpuid.com/softwares/hwmonitor.html It wil...

Re: Receive Stutter

Geoff, could you download and run LatencyMon and share the results? That should identify potential driver and process issues causing latency and/or page faults which are usually at the heart of the problem. Also, see my recent posts in the LatencyMon Benchmarks thread. You will see some good and bad...

Re: LatencyMon Benchmarks

Rob, that looks pretty darn good to me. I assume you have no issues with pops and drops. Now, let me show you a bit of history which might make you feel very good about your setup and help explain why I decided to do my latest build. This is a screenshot of LatencyMon sometime after my 2016 build us...

Re: LatencyMon Benchmarks

I don't want to publish that until I see if I can fix my 2D problem. Needless to say, its nothing to brag about. Also, I'm not sure that a 2D benchmark is relevant anymore. Other modern benchmark software ignores it. Scott (and others), check this one out: https://benchmark.unigine.com/superposition...

Re: LatencyMon Benchmarks

The new build includes a Xeon E5 2696 V4 CPU which I was able to get as a "new pull." I purchased some G.Skill 3200 RAM also but it is no faster with that processor than my old Corsair 2133. The E5 2696 only supports RAM speed to 2400 and if you try to OC the RAM, it won't post. So I have ...

Re: LatencyMon Benchmarks

Scott, as we discussed, the most significant benefit of my recent re-build is the reduction of latency to near zero. I ran LatencyMon with HPSDR and all related audio software for over an hour last night with beautiful results. I repeated that result today but eventually I would see a brief isolated...

Re: VAC Fails after Win 10 Creators Upgrade

Interesting comment on the Win sound settings. I just checked and found mine were reset to 44100 from 48000. However, everything still worked. While driver issues were expected as soon as the update process began, I was surprised that it affected something in HPSDR, and further surprised that the fi...

VAC Fails after Win 10 Creators Upgrade

MS inflicted me with the Win 10 Creators update over the last couple days. I have been reading that many of you had to reload various drivers as a result so I was not surprised when I could not get TX audio into HPSDR via VAC 1 using my ASI 5211 card. RX audio, which also goes through that card, was...

Re: New PC Build: now UPDATED with overclocking performance

Scott, wow! You're killing me on the graphics score and substantially better on memory as well. I noticed your Corsair stats and thought to myself that my CPU cooling fans had been running wild lately and checked mine. Temps were out of control; some CPU cores were in the mid-60's. A bit of research...

8000DLE Diversity Setup

I am just now putting my diversity antenna in line and found myself scratching my head. Reviewing the manual, I see a reference to "RF1" which is said to me "reserved." However, on my 8000, that connector is marked "ADC 2." not "RF 1." I am assuming that will ...

Re: Problems with original equipment fuses and fuse holders

One obvious answer to this issue is to use a RIGrunner, or similar, nominal 12 vdc fused PDU and direct cable runs from the PDU. Since I have approximately 10 12 vdc devices, that is what I have done and there are no fuses on the lines, only on the PDU. Works great and I have seen no measurable volt...

I don't see any problem with the 8000 sitting on the computer. There is no heat under the unit and it is well supported by the c...

Re: New PC Build

Scott, any driver/latency issues with your NVIDIA card? Guessing not since you are indicating a reduction in the drops and pops department. As mentioned, I was pretty disappointed in the video performance of the FirePro 5100 as per Passmark. Probably shouldn't have been a surprise since I could actu...

Re: New PC Build

Scott, nice build for sure! I'm having a bit of Passmark envy. I got an overall score on my Dream Machine of aprox. 5400. The CPU benchmark was 14k+ and the disk benchmark was 23k+ but I fell apart on the video scores. As you may remember, I went to the AMD FirePro 5100 to get rid of the latency iss...

Phil, I know that not everyone has the issue, or at least not to the extent that it is highly annoying. Don't know why, but every system is slightly different. I, also, will encounter the issue on a fresh boot - right from moment one. But, rebooting, sometimes more than once, will clear it eventuall...

Re: PureSignal Performance

Phil, while I know you addressed this question to Scott, I can tell you that I interface with my 8000 (and formerly my 200D) with a dedicated network adapter and it had no effect on the issue whatsoever. I, too, can also see it on tune, and I don't think VAC is the culprit. I do not believe it is a ...

Re: PureSignal Performance

Scott describes the issue quite well, as always. My worst glitches were associated with a video card that had a huge latency issue. After replacing it with a an AMD Firepro 5100, I saw a huge improvement but still had occasional "glitches." I initially thought rebooting HPSDR solved the is...

Re: Alpha 89 vs. PureSignal

For what it's worth, EBS in the OM amps can be turned off by a simple jumper on two pins on the control board. EBS in the Acom 2000A can be turned off by wiring a jumper in, which not hard to do but nothing like as simple as the OM's. I don't know about the rest of the Acom line. I can tell you that...

Re: External feedback level calculations

Stu, in the context of a run from the XDC-1 coupler to the PS sample input connector, I don't know what you mean by 50 ohm termination. The attenuator itself does not specify an impedance. The cable is 50 ohm coax. I assume the sample input on the 8000 is 50 ohm. The Ref. port on the XDC-1 is termin...

Re: External feedback level calculations

Based on my operational power level with an external amp, I ran the math as set out by Scott and found that I have about 6.6 db of phantom attenuation in my system with my 8000DLE. In other words, based on the math, where I should be seeing 26.6 db on the step attenuator, I'm seeing only 20. I gener...
