The indicator could look like this (look at receiver 3):

This would be the best option for me, as in my case the Receiver Pane slows down SDR Console significantly for some unknown reason.

I've clicked "yes" loads of times and each time the program restarts, if I click on the external radio button, I get the same window asking me to restart.

Re: Pluto via Ethernet - TX dropouts #pluto

Jean (DJ0VL)
 

I've seen that some OMs directly connected an LVT-354T to the GPOs. Probably works, but I would not feed comfortable with connecting a diode directly to an logic output port without current limiting. I designed a small PCB with a transistor driving the relay. 

The main issue with the recommended TCXOs is the output amplitude (the other issue is phase noise). The stock XO delivers nearly 1.8Vpp square output while e.g. the often named Abracon TCXO delivers a 0.8Vpp clipped sinus output. The AD9363 input requirment is 1.3Vpp, the adaption is implemented in the Pluto by a capacitive voltage divider. As the XTLAN input seems to be a logic input, the switching level may just be reached on the crest of the clipped 0.8Vpp sinus. This may lead to timing jitter resulting in spurs, poor phase noise etc. due to the low slew rate at the switching level. The AD9364 reference manual clearly states that a high slew rate on the XTALN input is required for best performance. The 0.8Vpp clipped sinewave output level of typically used TCXOs seems to be borderline, as it works for some or most of the Plutos, but there are many reports about spurs that appear after TCXO modifications.

I'm not aware of an easy way to generate 40Mhz out of the 10Mhz GPSDO output, but this depends on what you call an easy way. For my usage, I designed a low noise PLL driving a 40MHz VCTCXO that is locked to a 5MHz or 10MHz GPSDO output. It includes a level shifter to provide a squarewave with 1.8Vpp to the Pluto. A more simple way is to use a PLL-synthesizer chip like the SI5351a with the drawback of a poorer output signal quality with regards to phase noise. With a 50 Ohm load, the Si5351a can be configured to deliver the required output level.

According to the data sheet, you can feed in a 10MHz signal to the AD9363 (with a modified Pluto configuration file). As I saw problems reports when using a 10MHz reference, I did not try it out.

Until you allow the program to restart you wont be able  to see the external rig control window, so don't be shy click Yes.

XIT

David M0TGC
 

Presumably the XIT function is only visible when a transceiver is in use?

Could this be available when a receiver is used and transmit is via an external radio controlled by CAT?

When I am working full duplex, for example on QO-100, I select a clear frequency on the receiver, tune to it with my external transmit radio, make a test transmission and adjust the transmit frequency to correctly position my signal in the IF display.  If I then change frequency I have to do it all again but adjusting via an XIT slider would preserve it for the session.

Would this work or is there a better way to operate full duplex?

Re: RF quiet laptop

Jorge Garzón Gutiérrez <iberiaDX@...>
 

Hi,
I reckon that is a very wide open question as every folk here has different needs. I have an HP dedicated tower without permanent internet connection and I bought a Medion Akoya S3409 laptop. Why? I use it in the field or in the middle of the night on /p environment. I needed:
Retro lighted keyboard (to easier use with no light at all) 
Good screen contrast. 
No HDD to get the best in battery saving. 
Be rechargeable or operated from the cigarette lighter in the car. 
Built in aluminum to better dissipate the internal heat. 
Very light and portable.
It runs CSDR very good but if I tried to record 8 MHz band 2. Then it suffer some jumps that distort parts of the audio, so I use 6-7 MHz and that's it! Solved. 
I bought an external mini Toshiba HD and I store my i/q there. Then I can check them out very comfortably at home with the PC or the laptop itself if I am running an DXP. . 
Everything runs smooth and no problems at all. 
In the field I use the laptop and a Huawey 9,6" tablet to enter data and check info from the web or access to FMLIST account or DX forecast charts. 
That's all!

Re: SDR server manager

Ok thanks that is what I was thinking but was not sure i do have a rtl sdr on the way that will give me 2 radios and the name of the server running now is n0srz

Thanks for the help


Re: SDR server manager

Kriss Kliegle KA1GJU
 

Yes, One user per radio. Unlike SDR.hu or the Kiwi SDR network.

   So... put more SDR's on the same server (computer). What's the call sign or name of said SDR?

   I have one server (out of 5 total) with 4 SDR's and an IC-7100 remote base using the Icom RS-BA1 software. A powered USB hub will be required when you get more than a few online at once, for you will run out of USB ports and probably 5Vdc. Older machines (W7 Netbooks) have only two internal USB hubs, so place one on one hub, the other on the opposite side of netbook. Then try running both remotely at the same time and see how the ol' laptop/netbook handles it. My newer laptops (W10, i3 and higher) have no issues with all four on one port through the external powered USB hub.

KA1GJU Super Station #2 has the four SDR's since the antenna worked out so well, I placed as many as I could on that server.

SDR server manager

rudewarrior@...
 

I have every thing running.
the only thing I can not find is how to set the server to allow more than one user at a time.
 (i.e.) if I have a user logged on and I try to remote in it tells me that the radio is busy.
 Is that the standard per radio?

thanks.


Re: Pluto via Ethernet - TX dropouts #pluto

Jayson Bucknell
 

I'm going to replace the network adapter with gigabit USB to improve throughput. I have some LTV-354T optocouplers to connect directly across GPIO 0 and 1 for PTT. It should be enough to switch a relay or controller input.

The TCXO boards are recommended by others but I don't know about that potential issue. I have a 10MHz sine wave GPSDO I use with a hackRF that works though it should be a square wave. If there's an easy way to convert to an input I could use with the Pluto I'd definitely be interested.

External Radio not working #sdrconsolev3

roy@...
 
Edited

I'm trying to get my ICOM radio to work with SDR Console V3. I've checked the box in More Options and restarted the program. I already had Omni-Rig installed and that works OK with SDRuno to control the ICOM radio. But every time I click on the External Radio button, another box appears stating I must restart the program, which I've done loads of times. I'm at a loss as how to get it to work?


Frequency lock would be good to have

Roy VE7DH
 

A recurring problem I am having while using my Pluto to chat on 2m ssb is unwanted frequency changes.

With modern wide-screen high resolution multi-monitor displays it follows that the mouse pointer movement has to be sped up to cover the entire monitor space without excessive physical mouse movement. Unfortunately, that also increase the required positioning precision when clicking on a button, like the transmit button.

I have been finding that if I don't pay very close attention to my cursor position that I can accidentally click on the spectrum display instead of the transmit button. This can happen either when I go to transmit, or when releasing back to receive. In both cases it changes my tx or rx frequency.

I thought initially that a tx frequency lock would be adequate, then realized that since it also sometimes happened going to receive that maybe a general lock would be needed.

However, another thought occurs, that if there was a way to disable the the frequency change when clicking on the spectrum display then it would resolve the problem and still allow frequency changes from within the DSP panels.

So what say, Simon?  Would that be a possibility?

Thanks, and regards, Roy


Re: Airspy R2 only 625kHz via server?

David J Taylor
 

I fully agree with your calculations. But there is now way to "set" it. I checked all the settings in Console Server. And the client has only 625kHz to set. Maybe I am missing something here. Surely?

Pekka
=========================================

Pekka, Simon,

The specifications here:

https://airspy.com/airspy-r2/

say: "Experimental 2.5MSPS IQ output for low power devices (Raspberry Pi, Odroid, etc.) – Not recommended for high performance applications."

so I perhaps Simon will add - if it's not already hidden away or implied somewhere.

I've not used the ServerManager myself.

Back of the envelope calculations:

- say 120 Mbps available.
- one sample is 2 x 32-bit numbers, compressed to 24 bits each if the option
is available
- so 2.5 Msps available

Have you set the Airspy R2 for 2.5 Msps rather than 10 Msps?

Re: RF quiet laptop

myosotis123@...
 

Hi,

I use a Medion E4242 which has a very low specification (only 2 GB of RAM) but which will run from 5 volts and is very quiet RF wise.  Bought for another purpose I now use it for monitoring radio field strengths in the middle of a field or at the roadside with an antenna nearby.  The higher the specification the higher the emitted radiation perhaps, it would be interesting to see some tests on this.

Geoffrey.


Re: Airspy R2 only 625kHz via server?

Hi everyone,

I have SDR Console server configured in my "radio-shed". I listen at my house about 40m apart. I am using SDR Console v3.0.23 with my Airspy HF+ Discovery with success. It gives full 925kHz bandwith. But my Airspy R2 only gives maximum bandwith of 625kHz. I wonder why. Is it a Wifi speed thint or what. Server configuration maybe? Wifi speed is 130-144Mbit/s.

Thank you in advance,
