Please check the TCP Port field from Settings->EXT In/Out tab. It should be 6570. If you can't fix it, try to reset the settings to defaults from the main menu File-> Special Func.->Reset to defaults.

@@albertoferraris Thanks, i fixed it yesterday night by setting the port to 30341.

Hi, regarding r820t-based SDR devices, the slow scan is mainly due to the si4432 VCO settling time being about 50 faster than the r820 tuner PLL locking time. A faster scan can be reachable with other devices. For example, with an ADALM-PLUTO and SATSAGEN, the sweep time from 55MHz to 6000MHz takes about 600ms.

@@albertoferraris is it possible to use si4432 as sdr with pc interface just for spectrum analyser purpose? And what causes problem in spectrum analyser with fast sweeping timing as r820 is 50 times slower what limits this ?

@@omsingharjit Not yet, but I'll try to add that device next version. Regarding the r820 slow PLL locking time. Imagine you have a 100MHZ span to do (for example in a 100MHz to 200MHz sweep). An r820 / rtl2832 device allows a maximum error-free sampling rate of 2.4MSPS, which translates into an effective 1.2MHz of bandwidth following the Nyquist theorem. 100MHz / 1.2MHz = 84 steps. 84 steps * about 50ms (this is the time it takes the r820 / rtl2832 system to stabilize every step) correspond to about 4.2 seconds of sweep time.

@@albertoferraris thanks you , you did your best to explaining but , what I think I understood that it's not because of its Analogue parts of sweeping or Pall but instead it's slow because of Digital Conversion Like FFT , ADC etc right ?? And why chiper chip Si4432 is faster i have seen this chip is also used in Nano SA and heard that it's Sweeping based Spectrum scanning instead of FFt !! So is that FFT vs direct Sweeping Making Si4432 faster than rtl sdr based chip ? Or both chip Uses FFT anyway ?

@@omsingharjit The slowest performance is not due to a sweep-based or FFT approach (at parity of resolution band setting used). Moving the r820t VCO through the frequency of a sweep requires time, about 50ms every 1.2 MHz step. The r820t was designed for TV tuner application, where changing TV channels so fast is not required, except in channel surfing competitions! 🙂

Hi Paulo, maybe it's more simple for me to show what can be captured with SATSAGEN and PlutoSDR in this video: th-cam.com/video/8uIHNdKBjcA/w-d-xo.html

Thank you, Sandro!

Grazie Marco!!!

Thank you!

Something like a timer recorder?

@@albertoferraris no, in commercial spectrum analyzers the traces could be saved to a CSV file, if you set the time to say 10 minutes, the traces will be saved with names trace1.csv, trace2.csv and so on. Each trace file consists frequency on the X axis and magnitude on Y axis. If you could add such a functionality it will be quite useful. If You could provide any email ids I can send a few sample csv files too.

@@albertoferraris I would also like to add that in its current form too the software is highly capable. You have done commendable work.

@@deepakdkl25 Yes, I can add this functionality. Now you can export the spectrum data in one shot only with Export->Export Spectrum Data from the context menu. Please send me an email to the address shown on the about dialog of SATSAGEN.

@@deepakdkl25 Thank you.

Hi! Not yet. I'm still working to implement the VNA feature.

@@albertoferraris that will be great to be able to use the Pluto as a VNA up to 6 GHz 👍🙂

You are welcome!

Thank you so much, diggleboy! No, it's an ADALM-PLUTO not modified, with his original case, anyway the more precise TCXO, USB ground shield, and a metallic case are recommended!

Hi Marek, you could use a bridge or a directional coupler suitable in the frequency range of your antenna. groups.io/g/satsagen/topic/72873004 groups.io/g/satsagen/topic/72898815 th-cam.com/video/4cG018CzeK0/w-d-xo.html

@@albertoferraris Thank you

Thank you so much, Stan Tux!

Grazie Antonio, forse a breve metto la nuova versione disponibile al download, ha alcune funzionalità in più, spero che rimanga sempre utilissimo! Ciao, Alberto

Grazie!!!

Ciao Luigi, grazie mille per la tua graditissima testimonianza! Nel gruppo groups.io/g/satsagen stiamo iniziando a discutere sull'argomento tarature con l'aiuto esperto di Gianni IW1EPY, uno dei topic in questione è groups.io/g/satsagen/topic/swr_measure_with_satsagen/72873004?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,72873004. Una tua eventuale iscrizione al gruppo è assolutamente benvenuta! A presto! Ciao. Alberto

@@albertoferraris Molto bene Alberto, lo faccio immediatamente ... Con piacere continuo a diffondere questa tua "applicazione" in vari gruppi internazionali di noi Om , soprattutto a riguardo del transponder geostazionario Oscar 100 per il quale ultimamente sperimento molto sia in SSB che in DVB-S2 ove SATSAGEN risulta molto pratico in abbinamento ad Adalm Pluto per noi tecnici profani! 73 de Luigi IZ7PDX

Thank you, Georg!!! We working on developing a version for Linux, meantime I tested SATSAGEN on Wine and works well, with very little limitation!

Thanks, Alberto. I've installed SATSAGEN with wine (--version: "wine-3.0 (Ubuntu 3.0-1ubuntu1)", it was installed and starts up without problems. Tested only basic functionality so far - seems to work!

Hi Jempi! Thank you so much for your feedback! We working on to extend to VNA, but we don't found a cheap solution at the moment. I plan (I hope) to support other devices, stay tuned!

Thank you Andy! Provisionally, waiting next release, you can do it in this mode: groups.io/g/satsagen/topic/how_to_change_the_default/71917284?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,71917284
