To Eric and Dave, and others,

As an amateur and hobbyist in radio and electronics for 60 years, I?have?spent thousands on professional kit in the past, played with it, learned a lot but it has mostly lain idle for the last decad or two for lack of benchspace and time.

If I was honest, I doubt that I could get better results below 300mhz from all the professional stuff that I could not do with the current Tinysa, with the exception of ssb imd measurements (for which I can use a ?15 rtlsdr or rsp1). I could not walk around with a boatanchor for tracing qrm/qrn either.

The arrival of the nanovna family and Tinysa will transform my hobby. As I have said in a previous post, a uhf- only (300-mhz to 3ghz) version of the Tinysa would allow me to also play with low band wifi, newer phone bands etc.

Hi Erik,
My wishlist;
I wish people would get a sense of perspective, if they want the features of equipment costing thousands, they should go and spend thousands.

I wish that if what you've created isn't good enough for them, they'd stop grumbling and go and produce something themselves.

I wish that people would show the gratitude that the work of you and the team deserves.

-----------------------------------------------------------------------------

? ? A wishlist is not a demand, nor does it show a lack of appreciation.? I worked with Erik on the beta team and he knows I have the highest respect for both him and his work.? Erik is next to brilliant when it comes to squeezing features into the tinySA and has always welcomed suggestions that help the tinySA distinguish itself from the crowd.? If a requested feature isn't possible or lacks merit, he will not hesitate to let you know - and in most cases explain why.

? ?If there are no additional features you think can help to improve the tinySA then I'm happy for you.? If someone else makes a suggestion that they believe will improve the tinySA's marketability than you should leave it up to Erik to decide if the suggestion has any merit, and not assume the person making the suggestion? is "grumbling or showing lack of appreciation".

To all
Feel free to continue suggesting improvements. Sometimes I need feedback from multiple people to spend time on things that are useful but I'd rather avoid (such as updating the wiki, or changing colors of items on the status panel)
The feedback and requests from the beta testers have been tremendously useful.
W.r.t discussions started by suggestions, I would kindly request to "build" on suggestions e.g. improve on them.
Any suggestion is a personal view and has to be respected even if it seems ridiculous. If the latter, simply ignore.
I may react to requests or not. Don't read anything in me not reacting. I may be busy.
If you are (repeatedly) requesting something and no other people build on it, it may be something relevant for you, but not (yet) for the broader community. Which is not a problem, just something to be aware of

Can you give a bit of background on these

???? I have a Siglent spectrum analyzer I bought recently, and the tinySA has features that the Siglent doesn't have.? I can add some of those features, if I want to spend 500 dollars to purchase the firmware options.? Erik has done an amazing job of adding features to the tinySA!

Erik,
?1.? I would envision the editable transducer factor table being similar to your level correction table.? The main difference would be a menu option allowing the user to enter up to 9(?)? freq/value pair that are added to the displayed values as conversion or correction factors.? There may not be sufficient memory in the firmware to allow this with all the other features you have provided.? The other problem would be changing the display units, if say, the factors converted units from dBuV to dBuA.? Maybe something to consider adding to TinySA.exe instead.

2. The automated occupied bandwidth measurement is a feature one of my club members demonstrated on Siglent spectrum analyzer.??Occupied bandwidth measurements are used to measure the power of the occupied channel as a percentage to the power of the channel.? I 'm not sure what algorithm was used for the measurement. Jim Allyn?has a Siglent specan and might be able to shed light on the measurement procedure.?

1: Is clear. It will depend on available memory. Not sure yet
2: Occupied bandwidth is clear. Specify center freq and channel width and calculate the power inside and outside channel. probably use maxhold to get the curve.
