Got my B210 to work with the latest ver of 3. WENT TO THE ETTUS BINARY
PAGE AND FOUND THE EXACT SOFTWARE BUNDLE SIMON SPECIFIES. BE CAREFUL.
IT'S NOT WHERE THE LINK TAKES YOU. ONE PAGE BACK.
Have fun with the B210. It's a great receiver.

Re: Enable Doppler Effect Enabled - Not Changing RTL-SDR Frequencies #rtl #satellites

Hasan Schiers N0AN
 

Hi Simon,
I'm not getting Doppler to Work. Airspy HF+. Enable Tracking is set, Doppler displays in the beautiful tracking display, but the Main Display never changes frequency and the satellite drifts right thru the waterfall with time. It looks to me like the Sat section of the program is doing the doppler, but it is not being applied to the Main SDR program.

If I change sats, the main display does change freq when I click on a sat ...but I cannot figure out how to get doppler applied to the Airspy HF+

Re: World Map v1.0.5

Whoa ... Love the dual clocks. And I just got on to the funky short path / long path display.

Would it be difficult to add some sort of count-down or timer function that beeps when it runs its course? That would be world class cool. That would be very handy in my shack, as I often need to wait for X minutes to do something (not thinking of when to ID ... other timing functions come to mind) or time the duration of this or that event while operating. I know this is the stuff pipe dreams are made of, but the clock is so good now, this the only extra feature I would want.

Way cool as it is, of course. James K8JHR


Re: World Map v1.0.5

Richards
 

GREAT ! THANK YOU, SIMON.

And just in the nick of time! I was JUST about to upload a screen shot showing how the last version had the great circle image backwards - depicting North America in a shadow during daylight hours. It appears you have corrected this in the latest version.

Way cool.

Now, ... er... um ... Simon, would you prefer we buy you a Beer, or an Espresso, as a token of our gratitude? My favorite camera guru (UK photog Gordon Laing) suggests we "buy him a coffee" - but, I sorta wonder whether you would prefer a pint of the local best bitter? (Parenthetically, I like Stones Best Bitter made in Yorkshire... um... what is YOUR favorite frothy mug?)

Thanks again.

Hi,

 

Looking at this now, can reproduce an issue. Looks like it’s inside my own HF+ support code.

Hi Simon,

FYI, it happens on a local SDR as well, so it's probably not a Server specific issue.

Here's the DXDiag screen I saw on another thread that might be helpful.

No problem.  This is not a critical issue.

Hi Simon, Group,


I tried this program but upon starting it complain about a missing dll


api-ms-win-crt-runtime-l1-1-1.dll

I suppose there is an easy fix for it...

I do not have any version of SDR installed, running 64 bit W7 Ultimate

Re: Can I Manually Change the Sample Rate in SDR Console?

Simon Brown
 

OK,

 

Show me a screenshot while it’s running, also show me the screen below. It could be USB bandwidth.

 

I don’t drop the rate (I think), always use 10MHz. So check the USB side of things, you can always get a PCIe USB board…

Is this possible?

Does it automatically drop the rate on lower bandwidths?

Still troubleshooting the Airspy R2 stuttering audio with their support as well.  They think it's my computer, but it should be powerful enough and I do have the Nvidia GPU assist too.

AMD FX 6200 3.8GHz if that matters.

EDIT : of course, when I wrote : " Should I modify some settings on my HF+ before recording ?" I was refering to the setting from SDR# "source" window (HF AGC, HF treshold, HF preamp, HF att)

Le mer. 26 sept. 2018 à 13:57, Patrick <aunumero73@...> a écrit :
Hi there,

Last night, I made a recording on MW, using a my HF+ with its default settings (HF AGC ON, HF Threshold LOW, HF Preamp unticked) and SDR# latest version / firmware. Antenna is a Wellbrook ALA1530LN mounted outdoors.

Listening to the files right now on v3 (to run your amazing Data File Analyser), I notice the S-meter readings are very high and seem "overrated".
AM mode, 4 kHz filter reads -60 dBm on a "clear" frequency, and about -20 dBm on powerful stations.
Using AGC OFF with Gain set 0 dB even causes distorision.

When recording from an ELAD S2, the loudest stations read about -50 dBm. Similar values if recording with an RSPduo and playing back with SDRuno software.
That's about 30dB discrepancy.

Should I modify some settings on my HF+ before recording ?
What does explain such a hugh difference between both SDRs ?

(note :  a couple of months ago, I recorded from v3 but then it was impossible to use the file with SDR#, I mean the waterfall was totally saturated, no way to see a single signal even with contrast at its lowest).

Thanks for tips / suggestions

Re: S-meter readings when using an Airspy HF+

paul newcombe <G6YZC@...>
 

BR,

I love SDRC but think it should come with a bottle of Typex (White out) and the first thing you should do is cover up the S meter. 

When ever most people I have spoken with try to use SDRC and an SDR they immediately add as much attenuation in front of it as needed in order to make the S Meter read the same as their big 3 brick rig. The next thing they do is complain that the SDR is deaf and totally useless. 

I know on 2m EME my SDRC S meter reads somewhere around -71 dBm (off the top of my head) and I also know with a -71dBm noise floor you cannot do EME. So I just ignore the meter and continue to work stations off the moon.

Re: Nvidia cards in an older pc

Norm n3ykf <normanlizeth@...>
 

Simon,

Thanks for the tip. Considering a video card simply because it can be
transplanted into a new machine. The old pc has new ssd's and a new ps
(1Kw). Have been keeping up as things get too obsolete. If I stay with
the ATX form factor, it is just swapping out mobos. All of the rest is
there and up to snuff.

Have been looking at the NUCs. Upside is that it can go on the road
with me. Some are designed with power footprints that would allow a
reasonable run time on a battery pack. (something that you'd get on an
airplane) The down side is one thing blows up, it goes in the trash.
Upside of a pc in a box is that there are ways to "fix" or work around
failed components on the mobo. The ATX form factor has oodles of
space.

Software (V3) is waaaayy nice. Still figuring out how to use it.
Getting ready to read the manual. Like to get some hands on
familiarity prior to. Otherwise I feel like a dog watching TV.

Any video card will help as it will improve the graphics response, just make sure it supports Direct-X 10, 11 or 12. I don't see the Direct-X support for this card.

To be honest, a new PC should be on your Xmas wish-list.

Hi all!

My old pc, a Q6600 (first of the quad core avaliable at a reasonable cost)/Intel D975xbx2/Nvidia quadro 4000/4GB ram/1kw power supply/windows 10 is being tested by the latest suite of software for ham radio. No complaints here but Ver 3 uses a large fraction of all four core's processing power (CPU). Ver3 is a wonderful piece of software. SDR is an Ettus B210.

This beast of a pc stays around because it supports PCI. Have a bunch of NI cards that use that bus. Test gear runs most of the station.
It's (the pc) my development platform (LabView). Use a NI Enet/100 (ethernet to HPIB) as the bus master of the HPIB bus at the station.
One of these days I'll actually connect all the dots and have a fully remote shack. It's a satellite station, so full duplex and all the other stuff.

Was using an HP server DL360G5 to run the ham station when I purchased the video card (quadro4000) for a rendering project. It was more of a form factor/machine spec decision than a performance one. Had it running the ham station for a little while until the noise got to me.
Sounded like a jet spooling up to start. Too much.... Performance out the wazoo. 4x zeon quad cores+32GB memory. Very little space for cards and strict electrical requirements. It was a good idea to wear the headset in order to preserve what little is left of my hearing.

Plan on upgrading the memory on the old pc. 4GB was a splurge when I bought it 10 years ago. Memory is cheeep now. Throwback to the past:
Max supported 8GB. WOW!!!!!

Does it make any sense to add another video card to the old PC? I'm specifically aiming it at reducing the load on the CPU ( for SDRV3).
Was looking at the Nvidia K40. They are relatively inexpensive and plentiful on the bay. The server used x8 PCIe. This has three slots, x16, x8, x4. Planned on populating the x16 with a newly acquired card and the x8(with the quadro 4000).

Windows 10 has two programs running to verify software. They take like 25% of the processor's resources. I'm going to try tuning the OS. That can be like playing with fire.

Later on, I'll just buy a new pc. The problem is when the add ons start adding up.

This is the first time I've used a PC as an intergral, necessary part of the station. Used to be a radio, antenna, mic, a pen and a piece of paper. How far we've come.

Thanks, Simon.

Some additional comments.

  1. The breaks in the waterfall are from changing frequencies and changing back.  So that's ok, but the problem occurs about 50% of the time when I change frequencies.
  2. It happens on Narrow FM as well.  See attached.

Does it not like Jabra headsets (even though it's ok for everything else on this computer).  I tried updating the driver, but Windows said there isn't one and I didn't find one.
