SmartSDR 1.5 WNB - Flex 6300

  • 4
  • Problem
  • Updated 4 years ago
First of all many thanks to all at Flex for this V1.5 update.  However, the new WNB at my QTH is proving far less effective.  I have an electric fencer along with two neighbors.  In V1.4.16 I could eliminate all the fencers most of the time (depending on weather) and be able to increase the clipping level all the way up to 100% without causing any splatter from nearby stations, i.e. degradation of the IM. 

Now with V1.5 there is very little difference with it either on or off and the fencers are audible all the time.  It makes very little difference when I increase the clipping level.  Not only this but there is severe splatter from stations outside of the passband when I increase the clipping level.  I have tried to work out at what level the station has to be to cause this splatter, but to date have not been able to do so. 

This was a similar problem with my FTDX5000 and up until now the Flex has been such a wonderful rig to operate in comparison, free of noise from electric fencers.  Perhaps I shall have to go back to V1.4.16, but I really don't want to have to.  I should be grateful to hear what others who have electric fencers nearby have to say.

It is almost as if the WNB is not working at all.  Should I re-install V1.5 again?

This morning I had mercury vapor lights trying to go off. The new blanker didn't seem to do anything. Have played with AGC-T with no luck. Hope it's just me. Thought 1.4 had better performance too.

Hi Bill,

Been reading a little about mercury vapor lights. Sounds like they go through a several minute start where a little arc heats up the mercury until the main arc takes over. Does the noise decrease after the light heats up? I'm trying to figure out what the noise signature of such a light looks like.

Thanks,
Marco

Was hearing periodic buzzes. Right at dawn. We have MV street lights. Thought maybe one was going on and off, just a guess.

High Pressure Sodium not Mercury vapor light in my back yard comes on for about 15 seconds (warm-up) and noise goes away so not a real problem here.

I had mercury vapor but learned HPS are cheaper to run if you can deal with the orange light. I have a 70watt hps and give`s plenty of lighting.

The light does not pose a problem once on and going.

But I did engage just in time tonight and WNB took it right out.

Audio came through ok.

Hi Andy, 

Sorry to hear that this WNB is not working as well as the old one for you. Do you know what type of electric fence this is? Some of them put out pulses every second or two, others (older style, I believe) are more of a continuous AC output, and yet others charge a capacitor and discharge upon contact with the fence. 

Thanks,
Marco

Apologies Marco for not replying, but I have not been at home.  Today I have been doing some experiments.  I have done a factory reset but still have the WNB problem exists.  Can we communicate offline please?  I am in the process of making some videos.  My email address is andymartin@f5vai.com

Thanks,

Andy

My Gardner just came by with a string edger, the WNB completely eliminated the pluse noise from the receiver. So it works impressively on strong pluse noise.

What would be great is a mode to capture the signature/sample of the noise source and then allow customers to upload their signatures/samples which then can be incorporated into the product... I would even pay for that!  - It would even be nicer if you can use those signatures/samples to create a custom noise source sample that then the radio adapts to - even if it only just further improves the NB.    Most of my noise sources are pretty constant.. I would assume others would say the same.  Having an ability for the algorithm to adapt to the specific noise source through a station's sample would truly make this world class NB - would revolutionize how QRM AND QRN can be eliminated.

I made a couple of youtube videos demonstrating what WNB does to my local noise.

thats great Lee - I'll have another go tonight setting my AGC-T gain correctly

I think I missed this - have some TV noise from neighbours at my temp QTH this might help a lot!

thanks

Hi Simon  You can do this without the meter but the meter is very cool  N4LQ made a video tuning by ear

Ok lemme narrate Burt.....button off....noise....button on...no noise....button off noise...button on...no noise... etc. The point was to show a puny weak sig become copyable. I chose this demo because a friend of mine was interested in 6m noise blanking and this simulates a vhf signa in a sea of noise. I don't have any noise on 6. It was also to show the tune up carrier did not modulate the noise. Howzattbubba?

Lee,  Guess I missed this somewhere...  Where did you find the "Flexmeter" you used to set the AGC-T

Thanks Lee for the great vid on the NB. I am looking forward in trying it on 6 Meters in my noise fields.

Lee, re: narration, I hope you enjoyed mocking me. I teach 4th grade so maybe I have a mind of a 4th grader, however for me it would have been helpful for you to spend a minutia bit of effort to say what you are doing, even if you are CW only and rarely speak, ok?

1  The noise blanker speaks for itself

2  Sometimes less is more, and sometimes learning is about discovery not didactic.  My video was created very intentionally to draw people into the experience, and specifically to not control their experience and conclusion.  Given the overall amazing result of this piece of software, I did not want to color the experience very much.  The software virtually lets you hear under noise with virtually no distortion.  My video was created to show various operating conditions and to try and simulate conditions that do not exist at my station, like how this might operate with VHF.  The only thing I wish I had done was to blank the carrier in the USB vid as well, but I wanted to show that a strong local signal does not degrade blanker performance so it was a trade off.

3  The videos were intended to be viewed ideally as a pair.  There was a fair amount of narration in the first and repeated narration in the second would not have been parsimonious (4th grade word of the day)

4  I spent a fair amount of time on these 2 videos.  The problem with over narration is if you screw up the narration you get to start over since my capture software does not allow for much editing, nor am I interested in editing.  The screen casting software is free.  It is called OBS.  If you want a different result then get off your lazy ass and have at it as opposed to criticizing my vid or anyone elses.

Nice video Lee, to me, It would be fine if you had no narration at all. I was just interested what it would sound like with NB on and off.

Lee the only video I saw had no narration, what was the one with narration? How hard would it have been to do your video like this?

Larry, Www. Denzone.com. Problem is the site doesn't have a windows security certificate. So I needed to bypass my antivirus to allow it to load up, once I did it worked fine. The meter works well. Good Luck

I added a link to the "companion"video in each youtube description, and a link to FlexMeter  Hopefully this will give the google spiders enough to go on.  I couldn't figure out how to publish HTML in youtube so the raw links are displayed.  Hopefully this will improve everybody's discoverability

I just have it in a folder off of drive C: and a shortcut to the .exe on the desktop  SSDR I think needs to be running as well

Yes, it using the API, even with SmartSDR closed it will connect to the radio if it's powered, and show you the voltages before and after the fuse, microphone levels, etc.

do you have it turned on using separate computers?  In other words are you trying to connect 2 clients on different machines?

In some cases you have to allow both private and public through the firewall even though only one is offered as a default.

Then your noise source is not highly correlated and WNB will not be effective on it.  Not all noise has the same noise signature and characteristics and one noise mitigation technique will not mitigate all noise.  It is a your mileage will vary situation.

Please don't.  You never know when a well correlated noise source will appear that WNB will be very effective on.  These are all tools in the toolbox and learning which one is best to use for a particularly type of noise is important.  As my grandfather used to say, "you can't drive many nails with a hoe"

Would be nice to have the old NB still useable. So we could compare both (NB & WNB) and use the one that fits better for our noise problem...

(6300 still on its way) wanted to share my thoughts ... my ftdx3000 has both nb and and wnb each having its own "slider" setting. depending on the NOISE one works better than then other . I would agree having both is not a bad thing. Frankly I hope its added back with individual settings.
