Hi Phil

Yes, as per Sigi's answer, can confirm TX functions only appear with a TX capable SDR. Furthermore, some of those TX features vary to be customised for the specific hardware. PA/filter setup menus, specific gains, CW features etc. etc.

This may help further:

Hi
Thanks for the reply.But what I was really asking is, if I use a sdr dongle without transmit capability, does it disable the SDR console transmission function?  I just want to familiarise my self with all console settings even though I know I can’t really transmit.

Hi Phil,

 

within the next 2 days AMSAT-DL will offer a PA in their online shop which is intended to be used with the Pluto or Lime SDRs.

 

The gain is 46dB and thus you only need about -8dBm from the SDR to drive the PA to it P1dB.

 

The saturated output power is 6W and thus plenty for QO-100 in SSB and CW.

 

Kind regards

yes definitely it works

receives on 739 megs and transmits on 2400 megs IN FULLDUPLEX

you need an amplifier with "a few watts" (depending on dish size) that can be directly driven with say 0db (or better -10dm)

or a preamp in line before your amp

a dish

a dualbandfeed (a poty feed or a helix in front of your lnb)

its quite easy done with a pluto ... but pluto needs modding (replace tcxo or use external reference)

and lnb "should" be modded (also with external reference or with a tcxo)

here i have both only modded with a tcxo (no gpsdo) and it works quite well (0.5ppm in pluto and 0.2 ppm in lnb)

feel free to ask for details

Re: Version 3.0.26 Wobbly audio ?

Conrad, PA5Y
 

I spent 20 years in pro audio and felt the same about Behringer stuff. It was especially nasty in the early days and I would NEVER use it.

However, I must say that the UMC series of soundcards are better than we typically need in amateur radio use. I put a UMC202HD and a UMC404HD through various tests using an R&S UPV and it meets or exceeds the manufacturers specification. You must decide for yourself whether these specifications are good enough for your application, but what I can say unequivocally is that the UMC series of soundcards are not junk. The drivers work fine with W10 and are rather better than my focusrite drivers. Focusrite are supposed to be 'the good stuff'.

I have no playback or audio output problems with SDR Console 3.0.26 / Perseus and either of the UMC soundcards that I own. If you want more details of drivers and PC configuration it will have to wait until I am in the shack later.

Regards

Conrad PA5Y

I have tried recording via the SDR Console recording tab, the problem with that is regardless of the recording device selected in Windows Sound settings the recording all come out 100% OK.
Note quite the quality you probably need but attached is an MP3 that sort of demonstrates the problem with the Behringer audio, The only way I could capture this was to use a dynamic Mic held up to one of the speakers and record via Audacity. However, the recording doesn't quite demonstrate the problem  as each application I open (for example Audacity to record the file) increases the CPU Load which appears to reduce the Audio Playback Buffer value in SDR Console thus correcting the warbling problem.
The more the CPU load the less the buffer value in ms !

With the problematic Behringer Sound Device, CPU usage is about 15-20%, Audio Playback Buffer Value around 500ms
With the Realtek, CPU usage 20-25%, Audio Playback Buffer Value around 85ms

I've attached the 2nd screenshot from my previous post which i the one for the standard PC audio device (Realtek).

I've had a couple of goes at recording the console but each time after clicking the Stop button the recording information on the bottom bar continues to count the time but a message titled "Finalising" is shown together with 0 bytes for the file size.  Before recording, the CPU is around 1-2% and then rises to around 20% during recording and after hitting the Stop button decreases to around 1-2%. I can continue to use the console but when closing the program this results in a crash and a 0 byte file in the video recording directory.  Even if I stop the Radio the video time counter continues to count.  Any ideas anyone?

3.0.26 audio problems question 1 repeat

Zacharias Liangas
 

(1)Many times after using the Binaural mode and returning back to the standard AM mode the audio levels lowers by between 3 and 6 db levels
Does it happen to anyone also? 


Re: 3.0.26 audio problems

Siegfried Jackstien
 

zoom a bit out ... and DO NEVER USE THE 0 HZ SPOT

YOUR CRACKS IS WHEN YOU TUNE AROUND (FOR A MOMENT CLOCK IS UNLOCKED WHILE YOU TUNE)

avoid the 0hz spot ... zoom out ... and the tune in the passband of your sdr

no clicks anymore?? problem solved

not the soft is faulty ... the problem is between chair and keyboard/screen

Re: 3.0.26 audio problems

jdow
 

First go through options to tell SDRC to run at above normal priority. (Or for testing simply use TaskManager and a right click on SDRC's entry.) If that fixes the problem that's good. If it does not fix the problem you may have to go into power management settings and select an option that forces the computer to 100% CPU time. You may also get some benefit from a browser running in the background not necessarily doing anything significant. I am guessing you are running on a lap top. This may make these settings problematic.

Worst case your audio system may have a seriously poor oscillator setting the audio sample rate (or you messed with calibrating your HF+ and screwed it up.) Two clocks on a digital system fight each other all the time. Your audio may be asking for and accepting data faster or slower than the delivery from SDRC which is governed by the AirSpy HF+ clock. (I am betting your audio is accepting data at a slower rate than it is fed by SDRC.)

One gets spoiled for most of the knockoffs when one has had a chance to use the real thing. Behringer stuff is not bad, per se. It is not as good as what they were copying. The cost cutting shows.

Might not be expensive but I have some Behringer kit (UMC202HD for used mostly as mic preamp) and have found it excellent. I guess experiences may differ.

Re: FT8 checking my signal

With separate antennas it will certainly "work" during transmit. During receive a ham or broadcast station nearby could place a high enough signal level on the input to cause overload problems. HOWEVER, if the antenna used is moderate to high efficiency you can insert an attenuator on the input with little or no degradation on SNR to your ears or digital audio decoders such as PSK-31.

Well, It appears that the problem has fixed itself...ghosts in the machine !

Here's what I did/happened since I sent the last files to you Simon:
1. Disconnected the Behringer and threw it to one side
2. Re-enabled a couple of the standard PC Audio (Realtek) components, namely 'Stereo Mix - Realtek high definition Audio' & 'Microphone Realtek high definition audio'
3. Made up a lead to take the Audio Out from the PC/Realtek to the Monitor Speakers directly
4. Plugged monitor speaker into PC/Realtek, Realtek driver asked what I had just plugged in, confirmed 'speaker out'
5. Made Realtek the default 'Output' Device
6. Tested SDR Console all good

When you requested the log file, I reversed all of the above, namely re-disabling the Realtek components in Point 2, removing all extra leads, plugged Behringer back into the Same USB port as used previously,
made Behringer the default 'Output' device. Started SDR Console and now audio is perfect using the Behringer.
Additionally both the CPU Load & Audio playback buffer values are much lower - CPU: 17.7% Audio: 29ms when using the Behringer

No re-boots or other activities, other than closing SDR Console when not in use.

Probably not of much use to you now but latest Behringer screenshot & logfile attached. Wish I'd captured the previous logs now !

Thanks

Re: FT8 checking my signal

Roger Shaltry
 

Let me save you some money and grief.  I used my Perseus as a external receiver on my Elecraft K3.  There is a port dedicated to this use.  Worked for a few days and then blew out a $1000 radio.
Talked to Elecraft and they said that there is a pin diode switch involved with the external receiver port.  This seems to be common technology  That runs on 5 VDC.  When it switches it produces a pulse that will eventually destroy your SDR radio.
I ended up building a protection circuit for use on all of my SDR radios.  This has worked very well even with a nearby lightning strike (near field coupling) that blew out all of my USB connected equipment including the computer ports.  Never blew a protection circuit or the front end of any SDR radio.
Here is another solution (a lot less expensive then a new radio) buy a (about $40) Advanced Receiver Research preamp (HF or what ever you need) and use it ahead of you other SDR equipment.  I had lightning blow one of these preamps until I built my protection circuit for use ahead of all SDR equipment and preamp.  I have a 4x1 commercial splitter now and I use the protection device ahead of the splitter maybe followed by a preamp.
I may be able to locate the schematic and post it.
