Gary, I will have my new DP cables Thursday so that will tell the tale as to whether I have a cable issue or not. I'll let you know. Unfortunately, my issue is not solving itself. Hopefully, yours stays fixed!

Gary, glad you got your answers from Scott. Sorry I did not see the post until just now. Only one thing to add: I would think you should be able to disable the onboard GPU in the MB BIOS. While it would not be doing anything without monitors plugged in, it is still unnecessarily assigned resources b...

To follow up: I checked and found that my DP cables are StarTech DISPLPORT15L. They are rated for DP 1.2 but the reviews on this cable are pretty bad, many indicating a "flicker" problem, which may be the same as the random, periodic black screen issue I saw at DP 1.2. Looks like I have a ...

Gary, glad it stopped for you and hopefully it stays that way. In my case, all I did was move the computer from one rack to another. I extended the DP cables but it also went black when I did not use the extensions. There is nothing in that action which should have caused the black screens but it di...

Very nice, Scott. I love the colors, subdued lighting and overall clean look. 4k monitors are the bomb, particularly the Dells. I recently did what I thought was a small rebuild; really a relocation of the main computer and addition of a solid state amp. I moved the computer to the small (audio) rac...

Yep, they are fixing it as we speak. Also happens when you try to enter a number in RIT or XIT.

... Went on to say he thought WA0VY was having a similar problem and thought it was computer related?? FWIW, I did not have the exact same problem, at least as far as I understand it. I had the usual audio pops and drops in VAC which was more-or-less fully resolved when I did a new computer build. ...

OK, I got this baby hooked up and it seems to work pretty good. Scott, good to hear. Not sure what I'm going to do here yet but I did note that the BG7TBL distribution amps can be way out on delivery times. I do have a t-connector so I will try that first, of course, but don't expect it will work a...

I should be trying it over the weekend.

Excellent. I had a hard time navigating that site. I'll look forward to your report.

I've actually ordered a 3dB 0 deg. hybrid splitter from Mini Circuits and we'll see if it works.

Scott, let me know what model you ordered and how it works. Some of these are very expensive compared to a distribution amplifier, so I'm guessing I have not found what you ordered.

Thanks Jay. That's a nice solution. However, it looks like I only need two outputs, not three. So, I just ordered a t-connector for a few bucks. We'll see if works.

Ok Scott, I will give a try this weekend. Having reread your posts on this point, I wonder what you mean by "[t]he 1PPS needs to be properly buffered ...." Are you saying this requires something on the serial line connection other than the cable? Or are you referring to something internal ...

I received my BG7TBL unit today with a Bliley unit and am delighted to report a near perfect, effortless calibration. WWV at 10 mHz shows a completely centered meatball on Phase 2 in the panadapter with no correction dialed in. I could never accomplish that with a manual calibration. I have three de...

I can confirm these findings with two additions:

1. Waterfall high/low levels and spectrum grid levels also changed.
2. I am using the resampler version of 3.4.2, not 3.4.6.

So, it would seem that this glitch may not be new.

I also noted, and reported, a similar fan noise in my 8000. followed by a single recent high temp fault. I am currently uncertain that my fan is working at all and plan to get inside and do some testing to see if the fan has failed or whether the controller has failed.

Better link, perhaps? https://github.com/TAPR/OpenHPSDR-Power ... tag/v3.4.6

I use an Astron RM-50M and do occasionally run my 8000 barefoot full power in SSB along with a fair amount of peripheral 12 vdc stuff. The needle hardly moves past 25 amps on peak. At amp drive levels, the needle hardly moves. You should be just fine unless you plan to run full power, barefoot conti...

Fred, I run Win 10 and can't even find Win Media Player. You may be using an earlier version of Windows. I use VLC Media Player and it plays the files just fine. I also use Audacity to convert the .wav files to .mp3 which compresses and reduces the files to a fraction of their size. Give those progr...

Ok, missed the part about needing to be in DSB. However, I got the exact same result using phase and DSB as I did using USB and Phase 2 - just that the display looked somewhat different. Very nice little trick.

Scott, I assume you mean Phase 2? Wow, I was very close. At 0.99999960, it barely moves counterclockwise. At 0.99999959, it reverses and is noticeably faster. So, my ear did a decent enough job.

Well Scott, you ALMOST have me convinced that I can't live without one of these things. I had no idea there was such a variance in these devices and so may different things you can do with them. So, that commentary was very interesting. I currently manually calibrate and my correction factor is 0.99...

Note that, currently, is is nearly impossible to get rid of all glitches. There are some recently discovered issues with Windows Ethernet drivers and protocol stacks whereby packets can arrive out of order and which can prevent perfect delivery of data on certain systems. This issue is being worked...

I think its pretty much a universal problem, at least on the early production units. I stuck it to some waxed paper and put it in the box.

Thanks for the thoughts. It is difference in the magnetic and electric components of a signal that gives me pause on this antenna. All sources of truly annoying interference appear to be electric (power line or similar). I have an 80-10 OCF dipole that is still up in the trees but has been moth-ball...

For whatever reason, this blog would not allow me to post the last two shots in the previous post, so here they are:

I did not realize that this thread had gone into page 2 when I posted my last response so I did not see Scott’s or your last response before I posted. Sorry to hear that you have the dreaded latency issue. However, if it’s not causing drops or pops, resolution is more a matter of seeking perfection ...

Gary, I'm not aware that there any published "benchmarks" showing what others are seeing in LatencyMon (LM). There are published benchmarks associated with Passmark, but that is measuring overall and system sub-component speed performance, which is not the same as latency. As far as where ...

BREAKING NEWS!!! I did an update to the chipset drivers and achieved a somewhat interesting result. This is a 30 minute-ish LM result with HPSDR, ASI software and Firefox running, all of which usually present a challenging environment. IMG_1175.JPG Not bad. I took this shot with my IPhone. I already...

Basically, an i7 would be better for gaming while a Xeon would be better for server applications where you have to move a lot of data at once. There is a lot you can do with an i7 that you can't do with a Xeon. For instance, overclocking is limited (and difficult) with a Xeon and it can't use high s...

Update: I did some tweaking to the CPU power management settings in the BIOS and found settings yielding a significant improvement in latency with no real downside in terms of CPU temperatures. The settings all involved disabling anything that would reduce the power state of the CPU, even at idle. L...
