If all of the above terminate standard ATV and transition to the system the FCC forced onto the USA, all is not lost.  With our DTV signal, there is an unmodulated carrier nominally 310 kHz up from the bottom frequency allocation of each channel allocation.  This serves the same function as the video carrier in the older ATV system, but it is much stronger.  All is not lost.

The toolbar can be docked in the main SDR# toolbar window or floated in the undocked mode, this way if you have more than one instance of SDR# running you can drag the toolbars from each to wherever you want them ( or even to another monitor if you are using multi-monitor setups).

The toolbar button sets I have created so far are:

 - Detector Buttons
 - Band Switch Buttons
 - Memory Bank Buttons (10 memory slots where you can instantly store and recall presets)
 - Filter Bandwidth Setting Control
 - Squelch Setting Controls
 - FFT Setting Controls
 - AGC Setting Controls
 - Digital / Analog Mode Controls
 - Analog SNR Meter (< I may remove this before the plugin is released)

All of the shortcuts and toolbar button actions are shown with the on screen display control. Pressing shortcut keys or pressing the toolbar buttons has the same exact end result.



While I do not currently have a license for the Telerik theme controls, I have made the plugin so the controls look as good as possible with the new SDR# themes.
While not the same as Telerik's controls (they are just the regular windows common controls) at least they look like they can co-exist in the same space and my plugin windows respond to theme changes.

My question for those of you interested is this:

What other features / functions would you like added to each of the above mentioned items?

I would like to make this plugin as useful as possible for everyone.

There a few items that were in the old toolbar which will not be appearing in the newer version (the reason why was mentioned in other thread posts) 

So, if there is some cool feature or setting I can add, I would like to incorporate it before I remove the original separate plugins from my website and replace it with this one. 

ALSO - This particular plugin will only be compatible with the NEWER THEMED VERSIONS of SDR# (inclusive of the .NET 4.6 and .NET 4.8 framework versions).

Sorry, but I WILL NOT be supporting my plugins from the older versions of SDR#. 

Thanks 
Thanks Edward for these wonderful additions!
Are you aware you can draw the analog SNR meter in the spectrum display using the same technique as the OSD? This can free some valuable space in the tool bar.

You should pay attention to the testing conditions to get the correct interpretation. We are talking about differences within the component variability here because the exact same circuitry and processing are used in the FM band for both versions. Different units from different batches will still have very close performance but the inequality can change the other way around for this specific test.
The test mostly shows that both the HF+ and Discovery behave much better with very strong signals than older generation tuners.
Missing this point is like comparing A=1.0001 and B=0.9999 to C=0.5 then coming up with the conclusion that A and B are different while your uncertainty is 0.01. Of course, they will be different, but that's not the point.
As Leif said in a simpler way (but didn't demonstrate it,) the performance with actual FM signals with the standard channel separation instead of an unmodulated tone at close range should be the virtually the same.

Leif: Maybe this can be explained better for the non tech-extremists in a different video?

Hi Leif,

That's interesting. I thought the Discovery was superior to the Dual Port in this respect.

Hello Brieuc,

PSU Noise with #spyserver #airspyhfplus

Hello.
If I connect HF Plus directly it receives good, if I connect from the server (Orange) I see all this noise and spurs.
I tried disconnecting everything.
Some time ago there have been strong lightning, about a month and this has happened since. What do you suggest?
can you try my server sdr: //ik0mmi.ddns.net?
Thanks

A quick suggestion: you may still have analog TV transmissions from countries nearby (Tunisia, Libya, Algeria) that you can use to check your setup and as indicator of tropo openings. Lookup for a list of TV channels frequencies and their respective the audio frequencies.

The one shortcoming of the HF+ Discovery (and the earlier HF+) is limited bandwidth. Those receivers only receive a 660 KHz wide piece of spectrum at once. That's more than wide enough for listening to FM signals, but you don't the wider overview of the band that is available on the Airspy R2 or to a slightly lesser degree on your Mini. You could use the Mini for the panoramic view and then switch to the Discovery to listen to the signals.

Thank you for your answer!
The bandwidth isn't a problem for me, My Airspy is always set to 300 kHz bandwidth,660 kHz is indeed sufficient. I need a larger bandwidth for ATV and DAB receptions, but an Airspy mini is 100% efficient in my case on B3.
