Is there a link for the equipment used?

Does anybody know of a link to information on HughesNet internet receivers and PA?

All:

I've been testing Vara with an MCHF SDR QRP transceiver. The short video below shows the rig in action during a Winlink session: https://www.youtube.com/watch?v=jsc8XHiGi6c

Works well with reasonably strong signals - fast throughput!

Good  results are  being reported in the  VARA test  group

The reason being , that  unlike the HF  variant ,  the  FM coding

W6IDS Gateway Is Down For The Count This Time

W6IDS <w6ids@...>
 

Hello All,

In the FWIW category, depending upon your reliance on my gateway, I need to announce my system is no longer in service,
following the effects of the WIN10 5/16 Update. I didn't realize I had problems actually, other than there seemed to
be a lot of quiet time, per se. Then I saw a message from N2LEE which described issues he was having with Winmor,
ARDOP and VARA. That left him PACTOR only.

I decided to check and discovered that the same three protocols crashed on my system, leaving me PACTOR only as well.
My making connect attempts with other gateways resulted in ARDOP and Winmor locking up. VARA went into a 100% CPU
usage state and stayed there. It also would not respond to connect requests from a local, N9PTK.

Up until the Win10 update, there had been no apparent problems.

I encountered significant problems when I attempted to do a system recovery. I went through three sessions, with the
fourth ending up in a continual recovery process without stopping from 8am until 4pm today.

I downloaded a tool, a Windows Update Diagnoistic and got the system to reboot. It seems I have an Update Error
shown below. This may have been a continuing story because my computer has choked on updates before.

As an FYI, I downloaded Windows Update Diagnostic.diagcab which is:

Diagnostic Cabinet (306kb) from http://download.microsoft.com

The Error Code 0x80246010 is a Windows Update error, which prevents people from installing Windows updates for
both system and apps. Many people reported the problem when installing Cumulative Update KB4038782 for WIN10 OS,
but a variety of sites have detected quite a lot of threads complaining on this problem and indicating different
cumulative updates.

It has been reported in a number of websites that Microsoft's technicians are aware of the problem, but they are
not very active in responding to people's complaints. I saw messages about this going back to late 2016 in fact.
I found that one of the solutions offered by them is to install the needed update manually from Windows Update
Catalog. I'm no expert, but It seemed like a good idea. . . . however, I then read where those who tried this
method encountered still another error - 0x80073712.

The error 0x80246010 may be triggered by missing/corrupt DLL files, corrupted registry keys, incomplete updates,
malware and similar problems. In fact, I've seen it where the Update process suddenly disconnected from the
server resulting in a partial update install. Apparently, this can have a cumulative effect which isn't good.
I can't say I was aware of this.

I used the tool from Microsoft and was able to regain some semblance of control. I brought the system back up
and went back into temporary service. Immediately I had all three protocols lockup when connect attempts were
made, either outgoing by me or incoming from others.

Frankly, I don't think I will be able to quickly get my computer "spic 'n span" on this one. Not to appear like
I'm whining here, but I REALLY wish I still had my WIN7 software in hand. For my own perspective, WIN10 has
been a very sad experiment. Obviously, YMMV. Hmmmmm. . . . yeah, I know. There's LINUX but. . . . .

Howard can you go in to your update history see the name and date of what
all was updated then go to add remove programs and uninstall that update?
Just a guess what. I have never done that.. But I think it can be done.
It sounds like you already tried something similar? Or the restore may have
made that no longer available.. Just a thought.. I only know how to stop
WIN10 from updating and sending my info to MS.. Via their virus known as WIN
10.. lol.. And when and only when I want to do an update will it do one. I

Hello Jerry,

As a matter of fact, you can.  You go in through the Control Panel.  You can view the Update History, then select the Update(s) desired, then  select "Uninstall" and wait.  You do it for each Update.  Doing that now and just now uninstalled the 5/17 Update. Now, rebooting and will then go in and do another one.  Intend to go back to 5/9 Update.  Started this about 45 minutes ago on a whim, just in case.

Never tried this before - of course, wasn't desperate either <GRIN>.  My bad, I tended to regard Updates like bundles of "NITRO" - with caution.  I did try to do a recovery to an earlier Set Point  but failed as I mentioned.

Hopeful at this point.  I am turning off the Update process at some point here too.

BTW. Doug VE5DCP mentioned the same thing in another message. So, looks like I'm on target here - and for Doug, I agree. . . . we Users are nothing less than Guinea Pigs by George.  Doug also mentioned that he "turned off windows updates in services.msc table" in his message.  I'm going to get into that as well.

The only shaky thing is knowing enough to intelligently select how the Updates are chosen and applied.  What I do know is that the Updates are just killing me for their own sake and I need to get a grip on that.  These periodic system failures have gone on long enough for me.

Howard,

 

Are you sure it's not just the new sound card permissions which Microsoft added to the Spring update?

 

As I understand it by default programs which weren't downloaded in the MS store need to be given permission to use the computer “microphone”. If this isn't done the program usually bombs because from its perspective it can't detect the sound card.

 

It's an easy fix in Win 10. Go to Settings>Privacy>Microphone and make sure the little “switch” is turned on for allowing all programs access to the microphone.

Your hint may be a value point. This needs to be closer investigated.

Our local RMS Server as well met the problem of getting all Soundcards OFF LINE, for using with RMS Trimode. after this Spring update.
Nothing worked, except uninstall the update on both PCs.

Another Winlink server PC also got the Spring install, but in his case it worked after new enumeration of the sound cards.
Checking in to your hint, indicates than he may have switched this on.

Finn,

Also take a look in the new "Sound Settings" area of Windows 10.

There is now the possibility to assign sound cards and set volume independently to each program. Perhaps this is your issue?

I'm not an expert with Windows 10 (I use Linux) but I think this may be the cause of the problem for people since the Spring update.

Sholto,
Interesting, where do you go...step by step to get this menu?

This setting I believe can deal with issue too low volume for triggering the Signalink for its Vox circuit.

But probably not for the current case where Winmor TNC just show OFF LINE and no waterfall at all.

I was just there for a few hours Saturday.  I went back a second time to find the Newby Bridge Kid but they started shelter in place storm stuff and I decided to move on.  I was going to try get you a pint of Tartan.

Man. Can't believe I missed you 😞

Which day were you there?

 

Bumped into Bob Bruniga,  Bruce Perens and Mel Whitten but I’m upset I missed you old timer.

 

Going to any other shows this year? I’ll be at Plano in a couple weeks, Huntsville (Aug?) and Spokane in October.

Hey Sholto, I asked for you at the Dayton booth but you were AWOL.

Hm, Sorry, NO.
I switched it on, and let 1803 invade a couple other Winlink servers.
Not "enough" joy. Had to uninstall for getting all the sound cards modes in Winlink working again.
Winmor was the worst.
In some cases ARDOP 1 and VARA did play, but not Winmor.
Is it in addition some .net 3.5 issue mixed into this?

Thanks for the info Sholto,
but I do not find this kind of path in a couple of PCs, checked now, but they are back to 1709 installations.
May need to wait to new updates.

VARA vs. Pactor-III Speed Comparison Plots

Tony
 

All:

I've spent several weeks evaluating the on-air performance of VARA and Pactor-III under various conditions. The variability of the HF channel can skew the results when comparing modems this way so the data was compiled from an average of several test runs before a comparison was made. The tests were conducted minutes apart in alternate succession with modem run times of 5 minutes or more.

Speed calculations were taken from Winlink sessions that include the total session speed and file transfer speed in BPM. Tests were conducted on the 40 and 80 meter bands where multi-path and noise tend to be at their worse. The plots below, which were compiled from more than 60 hours of on-air test data, reveal some interesting results.


The first plot shows that VARA can exceed Pactor-III speeds by a considerable margin under the best channel conditions. They also show that the performance gap falls off to the point where Pactor-III eventually becomes the faster mode as conditions deteriorate.   


The next plot shows the results for the 80 meter band. Once again, Vara shines under the best conditions while Pactor-III tends to do better with under worse conditions. As expected, the additional noise and multi-path result in slower overall speeds for both modems. Under the best conditions, speeds on 40 meters were about 1.8 times faster than those on 80 meters. 


The next image shows the 40 meter and 80 meter speed data on the same plot.  


The next plot reveals a more detailed look at the poor signal performance between the two modems. Pactor-III tends to be the faster mode when subjected to low signal-to-noise ratios which would suggests that the low-speed Pactor modes tend to be more robust. 


The next plot is more interesting from a practical point of view. It depicts the total Winlink session time i.e., the time it takes to complete a session from start-to-finish. Pactor-III took less time than Vara under the worse conditions while Vara completed sessions in less time than Pactor-III once conditions improved. 



It would be interesting to see how the on-air data compares to the more accurate data that's possible using the controlled environment of a path simulator. If anyone knows of such tests, please pass them my way.
