During a big opening in Europe, I can have as many as 1000 decodes to go through after going through a recording of say 3 hours.

Automating the lookup can save a large amount of time!

Thank you, as always, for your amazing contributions to the hobby. 

This is an excellent idea and one that I would like to see implemented. Here in the United States, I generally can safely ignore decodes that don’t include the city and state of the station. But what happens most often while listening to meteor pings overnight is that the RDS detector will return a decode that shows the PI Code, call letters, and location of a legitimate station—however, when you look it up, it’s on the wrong frequency—meaning that the decode isn’t valid. 

Simply comparing the station's call letters and frequency to the VFO frequency is usually enough to determine that it’s invalid. If SDR Console could perform this function and add the ? symbol as you suggested, it would save some time each day. 

The Excel spreadsheet is another option, but it’s easy enough to look up stations here using the WTFDA database, so the Excel option wouldn’t really be much of a timesaver for us.

The EEPROM could not be read? Ah that suggests an installation issue of some sort. Without that determining much of anything about the dongle itself is impossible.

Hi again Simon,

I am not specifically interested in VHF. I have several analogue radios which will cover that, but SDR-C on my Laptop works brilliantly, so to be perfectly honest this has developed into being of academic interest only. I also have a SDR-Play which works fine.

Cheers,

Chris

Thank you for your input. I think I understand what you are getting at, but with all due respect it does not really solve the mystery as to what happens when I change frequency using the mouse on the numerical tuner in the DPS.

I have replaced the RTL820 dongle with my Airspy HF+ and that works perfectly fine. Noting that he Airspy HF+ will only allow a BW of 768kHz, I re-inserted the RTL820 and changed the BW to 750kHz. This did not solve the problem. The RTL820 works fine on the SDR-C I have installed on my Laptop running W10. IMHO it would appear that the problem is due to some miscommunication between this particular system and the dongle. I cannot help but conclude that I am flogging a dead horse and I will just have to accept that this is one of mysteries of life and move on and simply use the Laptop.

I know that Simon is allergic to videos, so just in case someone has a flash of inspiration, I have taken a few successive screenshots which will hopefully provide a graphic record of what is happening.

This is the screen when I start SDR-C:


All this looks normal as expected. I now advance the tuner 3.0MHz to 121.2:

All looks quite normal. Now watch what happens when I increase the tuner by another 1.0MHz;

Even though the vertical tuning bar #1 (if that is what it is called) appears to be at 121.3MHz the received signal does not conform with that frequency and the 120.9MHz signal remains at the centre of the display.
If I now reverse the tuning back to 120.9MHz the received signal is lower than the 120.9 Peak, which remains in the centre:

Now if I advance tuning by 7.0MHz to what on the DSP is displayed as 121.6MHz the display looks like this and the tuning bar is to the right of the 120.9MHz signal, which is still in the centre:

Now if I move the frequency shown on the DSP to backwards to 121.5 I receive the 120.9MHz signal again!

If I adjust the frequency display in the DSP to 120.9MHz I get this:

All mysterious stuff !
The only way I can get the 120.9MHz signal to correspond with what is shown in the DSP panel is to Stop SDR-C and re-start

Re: RDS Detector & Database

Nigel Pimblett
 

I too have found the RDS decoding on SDR Console to be excellent.    The one downside of tying the decode to the frequency is the case when the station is using the PI code for the originating station of a network rather than its own call letters.   I can think of a couple of small religious networks in the CO/OK/KS area that do that, and no doubt there are others across the US.    Checking whether the code is valid (regardless of frequency) would definitely be advantageous though.

Re: Question: vertical stripes in waterfall

Marcus,
Simon is 100% correct. The dual dipole Radio Jove antenna was designed for receiving Jupiter storm signals on a single frequency. The antennas highest gain (the bright green area) indicates the resonant frequency of the antenna. While not a broadband antenna it is somewhat useful over a larger bandwidth at a reduced gain. Yes the random vertical straight lines are most likely due to lightning either local or distant. The other artifacts do not appear the be Jupiter.

Hi Simon,

Screenshot showing <Home> ribbon bar:

It is getting murkier. This time when I tune to 123.9 I do not get the 120.9MHz audio, however the 120.9 peak remains in the centre.

In fact when I continue to increase the frequency nothing happens, but the centre of the screen still shows the 120.9 signal peak.  Now comes the bizarre part: If I now decrement the tuner in 1 MHz steps, the 120.9 signal is heard at every 12*.9 selection.

Just a screenshot showing the <View> ribbon bar
The mystery deepens!

If a station appears at various frequencies while you change the tuning, then something's borked.

So, two screenshots showing the station on two different frequencies. Please make sire the Ribbon Bar, Home panel is fully visible.

Re: RDS Detector & Database

Les Rayburn
 

Simon,

Thank you, as always, for your amazing contributions to the hobby. 

This is an excellent idea and one that I would like to see implemented. Here in the United States, I generally can safely ignore decodes that don’t include the city and state of the station. But what happens most often while listening to meteor pings overnight is that the RDS detector will return a decode that shows the PI Code, call letters, and location of a legitimate station—however, when you look it up, it’s on the wrong frequency—meaning that the decode isn’t valid. 

Simply comparing the station's call letters and frequency to the VFO frequency is usually enough to determine that it’s invalid. If SDR Console could perform this function and add the ? symbol as you suggested, it would save some time each day. 

The Excel spreadsheet is another option, but it’s easy enough to look up stations here using the WTFDA database, so the Excel option wouldn’t really be much of a timesaver for us.

Re: SDR Console with W11

That little keyboard changes the front end's tuned frequency. Since it is 10 MHz wide and you made a small change the receiver can both remain active and as expected on the same frequency. All that little keyboard does is change where your receiver is within (or outside of) the front end's 10 MHz bandwidth. You can define multiple receivers each with a different tuned frequency. That is you can listen to repeaters on 448/060MHz and 448.000 MHz and 446.040 MHz all at the same time if your front end is (nominally speaking) anywhere between 443.060 MHz (about 443.6 MHz to avoid strange effects) and 451.060 MHz (again 450.4 MHz would be better). All three receivers would remain running on their tuned frequency. One thing you will notice is the bottom of the waterfall will show a shift in its frequencies an the active bandwidth when you tune with the little keyboard. That would show the effect I mean.

I don't know if I found the right words to explain. If not I'll try again.

"Nothing like" means that if I tune to another frequency e.g. some 1.2MHz higher (A known active frequency), the expected transmissions are not heard. I tune by placing the cursor over the numerical display in the DSP and rotating the thumb wheel i.e move the MHz from "0" to "2" and the 100kHz from "9" to "1", or by selecting the from the <receive>ribbon and entering the frequency direct via keyboard.

There could be static crashes in there. There could be actual signals from valid or EMI driven sources. These could be IMD responses within the receivers' front ends. At least one is a frequency sweep from ionosphere condition probe. (That would be the diagonal line.)


The scales are too smudgy for my old eyes. Pictures that are not shrunk down to unreadable blurs might help identify some of the spectrum lines.

Hello, Question to the radio operators! Have now set up 2 antennas. So 2x dipole directed on the 15 meter band at a height of 3 m to receive Jupiter (Radio Jove) at 20.1 Mhz. Receiver sdrduo. Software sdr console. At 20.1MHz. Bandwidth: 6KHz. 15-24Mhz bandwidth for Jupiter. What are those many vertical stripes in the waterfall? Thank you for the answer. Greetings Markus

Re: Stupid Question

On ribbbon bar transmit.. Engage dsp (means show tx box)...
But.. Even if you see it.. You can not work on it (change settings) cause it is greyed out without connecting a pluto.
So you can connect YOUR pluto.. Make settings.. And then connect the other when its there..

Hello all,

I am trying to setup the program before I go to my friend that has the Pluto.

I am noticing that if the Pluto is not plugged in the PC the TX part is not shown and I cannot set the TX Part.

My stupid question is: Is there any possibility to make TX settings also when the Pluto is non Plugged in the PC?
If yes please how to able the TX part so I can do it?

Thanks
