Hello Gerard, I tested/ measured yesterday the second RF board, which is used for the tracking generator. The 2 SI4432 modules, the SAW filters and the ADE-25MH mixer are working fine. Obviously I

Hello, I did some tests again!! I reversed software Analyzer? spectrum and tracking. From a physical point of view, it is the same at the level of electronic components. Modified the CS of si4432 to

Hi, *Does not hold this assertion on the message above* "I think this one should be in Low in signal generator mode and not in High as in lowspeed analyzer. I think not possible to have lowspeed and

Hello Joerg, You have, I think, a somewhat different design if there are 2 RF cards. There must not be an RF? "switch" as on the latest M0Wid design. I think this one should be in Low in signal

Hello Joerg, Thank you very much for your tests I am in uncertainty and thanks to you I will move forward. we will be interested in version 0.15 and SimpleSa with M0wid PCB First: You must ensure that

Hello Gerard, I just checked, which SW versions I have on my SimpleSA's: - I have 1 with V2.8, that I modified to work with a 480*320 pixels ILI9488 display (I have only been successful with that

Hello, I will give you a few elements of progress: 1) I repeated a check of the welds and components, possible short circuits, etc. *Nothing to report.* 2) Then I did a test by changing the address of

hi, In the end, I don’t know if it’s here, as if we were blocking the whole tracker part? see in the SimpleSA tab: */ pinMode (SI_TG_LO_CS, OUTPUT); *digitalWrite(SI_TG_LO_CS, HIGH); // make sure

Hello Joerg, Thanks for your answer Version 0.15 is here [email protected] | Homebrew spectral analyzer (

Hello Gerard, I am reading your postings, but struggling, to understand what you are referring to: - you are talking about a version 0.15. Where is this version? The latest I know is 0.12, which is

hi, Can someone confirm that the signal generator and tracking work in version 0.15 with the given circuit model. I checked everything on my PCB. It looks good. Strange all this. Is anyone still here?

hi, i also read some pb's with mixers and filter?provenance function It also complicates the task of whether they are good or not. test their impedance? * cdt

Good morning, I reply to this old post (2020) because on my homebrew Simple SA, *I have the same symptoms that Joerg, ex-DB2OO? (see his screenshots)* Yet I have a *version 0.15 * Dave said these

re, I think that’s in line 308 of the Siglo tab I am not an arduino specialist, but this line will only display "set frequency" It must be modified to display the real? frequency value of the

Hello, I was busy for several months on other things, including troubleshooting YokoGawa oscilloscopes and Rigol. I took over this project. I had a Si4432 module out of service and I replaced it.

Ok, more progress. ?I swapped the MPF-102 transistors with SMT J310’s (soldered carefully into ME Pad SOIC boards) and added some leads to create a leaded J310 equivalent. ? This gave me higher

Hi, c13 on the 100 MHz oscillator should be 10 pF not 0.01 uFd. ? The Ashar Farhan Specan schematic on his website shows a full schematic and further down a smaller schematic that focuses just on the

hello, I never made a specan. I don’t know the software and how it works Try on the forum BITX20 /g/BITX20/search?p=recentpostdate%2Fsticky%2C%2C%2C20%2C2%2C0%2C0&q=specan cdt

I have run Specan on the Arduino, working; but no luck running Specan-UI on Windows 10 to get the plotting working for a sweep of frequency. ? I found a Chrome Extension on GitHub and also tried this

Ok, sorry to burden the group. I resolved the problem by inserting a delay(1000) statement inside the code as follows, so it seems this now allows the frequency to now be displayed on the LCD display!
