hello simon, first of all congratulations for the great work and development of the console v3.
Last week in the vhf contest, I had some very strong signals at nearby frequencies, and I would like to know if you would be so kind as to add smaller bandwidths, such as 50kmz and 100khz to increase the performance and selectivity of the RSP1A.
would it be possible?
My group of friends and I, who have been using your great program for some time, would be eternally grateful to you.
many thanks.
Re: Telemetry Beacon question

Siegfried Jackstien
 

the frequency of the beacon is preconfigured already to 10.489.750 .... (so no need to change it!!)

see how downconverter has to be set in radio definitions

and how to use telemetry beacon the right way

https://www.sdr-radio.com/EsHail-2#TelemetryBeacon

.....

if your lnb is way off (beacon is not even close to 750) ... then just edit the converter frequency till you see the signal in the beacon window at (or near) 10489.750 ...

Hi,
I use a sdr-console v3.0.19 with a limesdr mini 1.2 and try to use the beacon on 10489.750, but cannot setup this frequency as in the geobeacon frequency window, the list contains only 10489.000 ! How to tell the software the right frequency ?

Re: Lime Mini - HF

the datasheet of the switch says that the return loss comes mainly from the decoupling cap ... so increasing its value should lower loss and increase return loss

Hi Onno,

 

nice to have you here in the group.

 

If you look at the return loss of the switch you can see that it degrades strongly at lower frequencies.

 

At 100 MHz it is only 4dB.

 

I am not sure it is due to the DC decoupling capacitors on the demoboard or possibly due to internal AC coupling.

 

I suspect it will get even higher at lower frequencies and also the insertion loss will go up.

 

Kind regards

Hi

 

Firth a have to thank Simon for inviting me to the test team. OC I accepted it.

 

I did some testing with the mini.

 

Rx en TX works with the dll swap. Down to 3.6 mhz

 

I suggest the following:

 

RX:

 

Replace T4 by TC1-1TX+ (MiniCircuits) (thanks ED)

Replace MN19, MN22 C25, C26 (510 pf) by 0.01 uf

Remove MN20


TX

Replace T2 by TC1-1TX+ 

Replace C14,C15, (510 pf) by 0.01 uf

Remove MN23 (if populated)

 

I doubt that the attenuation comes from the SKY13411-374LF RFSW_Rx switch.

This switch is made for wifi rx tx switching. How should it blok frequencies < 30 mhz ? 

See attached datasheet. The lower the frequency the less insertion loss. Why suddenly a big loss < 100 mhz ?

 

I still have to check if the not connected pins AN 11 and AM 12 are enabled by choosing ant LNAL_NC;

If so a dedicated modification with a TCI-1TX+ to a dedicated SMA plug is possible (pity that the RFSW switch only has two lines). 

And I have to check with a scope before and after the switch for signal loss. 

Greetings

hola simon, en primer lugar felicidades por el gran trabajo y desarrollo de la consola v3.
La semana pasada en el concurso vhf, tuve algunas señales muy fuertes en las frecuencias cercanas, y me gustaría saber si sería tan amable de agregar anchos de banda más pequeños, como 50kmz y 100khz para aumentar el rendimiento y la selectividad del RSP1A.
¿seria posible?
Mi grupo de amigos y yo, que hemos estado usando su gran programa durante algún tiempo, les estaríamos eternamente agradecidos.
muchas gracias.

I see that power output should be lower at lower frequencies because there is a fixed value capacitor in series with output path, actually two of them. These caps values may not be high enough below 30MHz but I do not see that is a big problem because external amplifiers have higher gain at lower frequencies. Same for the RX path since noise is higher at low frequencies if antenna is big enough, so we need less gain settings at lower frequencies. No big deal. 
Recording audio of all VFOs in matrix view ! #bug

I make 6 VFOs in matrix view for analog Nfm frequencies,, but when I try to record sound .mp3 it's just record the specific selected frequency! Not record all active VFOs in matrix view !!! Please add capability to record all active sound from all VFOs in matrix view ! THIS IS BIG IMPORTANT TO RECORD ANALOG Trunk radio system ! 
Re: User configuration for a newbie??

martin m3ghe
 

Tom, don't take this personally. But try reading what I posted. I said the SDR-4+ wasn't CAT controlled. The SDR-4+ and the Sentinel 4 are different radios.
There is no such radio as the Sentinel 4+ SDR.

Martin
Re: User configuration for a newbie??

Tom Crosbie G6PZZ
 

Sorry to disagree Martin but my Sentinel 4+ SDR IS CAT Controlled. See http://www.crosscountrywireless.net/sentinel_4.htm  “ Cross Country Wireless Sentinel 4 general coverage receiver...a VLF/LF/HF SDR receiver with CAT control”

I have not seen the “…using Sentinel with SDRC…” note before or perhaps more likely the significance didn’t sink in until now. Now that I want to use HDSDR. I was happy with that until I bought my RSPdx earlier this year. SDRC makes it sing in my view. I’d prefer to just run my “fleet” on just one piece of software

 

I bought my Sentinel sometime last year when there were a few options available. I’m fairly certain I bought a 4+ with CAT control. Perhaps in my ignorance I ordered the wrong thing. I will check back with Chris as I may be barking up the wrong tree.

However, you have got me further on and I’ll have to play around more with settings etc. First of all will be the other option in Softrock. Cabling will have to wait for another day when I have more energy.

 

In the meantime, thanks once more for getting me this far.

 

Tom

I'm not familiar with the Sentinel. But the SDR-4+ isn't CAT controlled.
The CCW states that if using the Sentinel with SDRC that you use "Soundcard receiver option, tuning over narrow range with CAT control, needs mod to program or use with a datamode program for CAT control".
So in that case in definitions select  SoftRock then XTAL. Select your soundcard and in the Frequency box put the centre frequency of the range you are going to park the radio on.

Re: Lime Mini - HF

I modified mine about a year ago and if I remember correctly, there was no mod for the Tx side.  I used the Broadband (100kH-400Mhz) version and got good results for the input match:  ( the bold traces are the modified version and the light trace is the original).

Re: User configuration for a newbie??

Martin,

You might have read my earlier reply to Brian, late last night.

I have been struggling with the same problem for months. I had installed the drivers you suggested but I downloaded again, accepting all the defaults as I had done before.

I didn’t know to select Softrock then Si570 so I did that and ran into a “No Softrock Si570 Radios found” dialogue.

I was going to try the I/Q output but I like your other suggestion of connecting line out from the Sentinel to the audio in on the motherboard. It has a Realtek HD audio chip on board and I’m not up on audio chips etc.

I did get a quick reply from Chris at CCW about audio and I/Q but he left out the bit about which socket was which! Maybe you can help?

My current set is a Win 10 PC, Control panel reports that COM4 picks up the CH430 soundcard from the Sentinel The sound input uses the windows CODEC which OmniRig and HDSDR seem happy with. My station is currently undergoing a re-wire but I’m a bit limited by mobility issues following a stroke. The obvious things to most people aren’t as obvious to me!

If you can help me get a bit further, I would be grateful. I hope Brian is having better luck!

Nice to meet you.

Brian,
Ensure you have installed the SDR-4 drivers from CCW, they are on the disc that came with the radio. If you don't have it you can download from CCW http://www.crosscountrywireless.net/CCW%20SDR-4+%20setup%20program%20v1.04.zip
Then in definitions you select 'SoftRock' then Si570. 
Make sure you select the correct soundcard. If you are using the onboard USB Audio CODEC it will only give you 48kHz  of spectrum, if you use the line out on the unit it will give you what ever the maximum of the motherboard is.

Hope this helps.

Martin

You can't SDRC doesn't deal with RSP1 via TCP, just USB.
In fact SDRPlay don't offer that option in SDRuno either. Mostly because it limits the functions so much.

Use the sdr console program in local network with my sdrplay RSP1 #sdrconsolev3 #sdrplay #network

Hello
I want to use the sdr console program in local network with my sdrplay RSP1

But i can't make it


I can use sdrplay with the hdsdr program (via rtcp server) or cubisdr.
sdr console works fine if i connect sdrplay via usb

I have a raspberry pi4 with this image
https://www.sdrplay.com/downloads/
RPi Image - V0.6 (16th Aug 2019)

I use
rtcp server and port 1234
sdrconsole does not give error when trying to connect (connection error ....)
To configure sdr console I do
select radio local definition and edit sdrplay rsp1 and change ip
I have to edit my sdrplay configuration, because if I try to add a new receiver, I don't have sdrplay from add button
And from the search button, it only finds sdrplay if it is connected via usb

How can I connect it?
Greetings
Thank you

one should measure the output power AFTER the modification ... and ... tx power is not the only point ... what about rx??
