Re: New tinySA control program for Windows
Yes if he gets stuck I'll guide him if he needs it. There is like 20 or 30 thousand lines of code (or more) there I've already written for the VNA past month or so, so he's off to a good start there !
I fancy a holiday now though, can't go anywhere (the UK has just gone exponential again with this virus so lock downs are on their way back) but I can relax and do nothing and do what ever takes my fancy when I fancy :)

Just received my tinySA - it's on charge at the moment. A new noise has showed it's ugly head a few weeks ago at my QTH. A wide pulsing burst occurring about every 1-2 seconds at S7 !! And swamps? about from 3 MHz to 14 Mhz How can I use the tinySA to try to identify/locate what it is? Any help, ideas, instructions wold be very welcome.. -- Dave KK7SS

Hi Walt, welcome!
Its a big step from a 141 to a tinySA, you will miss the narrow RBW filters but at least the tinySA has a stable LO.
Don't drop it inside one of the Hallicrafters, you will never find it back.

Good morning?group,
I got my tinySA three days ago. I have downloaded tinysa.exe and paired my tinySA to a TAB PRO S tablet. I was guided to this site in a discussion about the tiny on another site. I got the tiny as a replacement for my 60-year-old HP141 that died again. My prime
use for the tiny is, analysis and repair of Amateur radio ssb transmitters and receivers. So far, I am impressed with the little guy. I have used it to look into balanced modulators and some xtal filter schemes.

Variable Horizontal Grid Lines
Erik,
No rush to respond as I know you are on travel.? With V1.0-86 Changes: specifically the increase in minimum number of frequency grid lines to be shown,
the variable horizontal grid line spacing can become visually distracting:
Automatic horizontal grid-lines after changing start frequency to 1MHz.
Can a display option be added that limits the horizontal grid lines to the previous default of 8, or at most 10, for those users who prefer a more conventional screen scaling? - Herb

Re: New tinySA control program for Windows
The marker placement issue happens when the total scanned points is large than the amount of pixels in the graph

Erik, ? I just tried Cathy's latest main NanoVNA-App branch, which adds your changes for communication with the tinySA, and it does not have the marker placement issue.? You might want to merge her marker placement code into the NanoVNA-App for the tinySA. ?  ? I also asked Cathy if she would change the vertical units to dBm instead of dB when in the tinySA mode, and? if she could remove s11/s21 from the chart when in the tinySA mode.? Could you consider doing the same in your branch? ?Cathy got the marker placement issue correct but her tinySA mode does not handle combining multiple segments properly.? Your branch does handle that correctly so be careful not to merge the incorrect segments code. ?- Herb

Hi Bill,
Thanks for your reply.
Hello from across the pond. Our daughter in law and son live here in Manchester UK. She is American and hopes, COVID willing, to visit her mother in Kansa City over Christmas.? My wife and I have fond memories of visits to the USA (Texas, Missouri, California / Nevada).Listening on?my?Eton E5 RX in Tahoe I was amazed how strong the WWV 10 MHz standard frequency signal was. Before it moved to Boulder it was an excellent calibration signal here in the UK and now is too weak.
My experiences of Amazon UK have always been positive having purchased a number of electronic?items for my ham radio.?? The tracking information was put up on the day I ordered, Sept 13th, and is now saying the tiny is arriving tomorrow. The puzzling thing is the message that was sent by Desuan510 saying that it will be arriving later due to the first item being damaged. Another UK forum user had an identical message and chose the option of stopping his order whereas?I chose to wait for another tiny Sa from Desyuan.
I do not know what the tracking will show later this week but wait with interest.
I shall report my conclusions to the forum about my order probably next week. If my order was to a scammer both Amazon and other potential buyers?need to know.

Hi Phil,
I am not in the UK. I odered my tinySA through Amazon here in the U.S.
and the seller was Seesii (never heard of them before). Over the years I
have had a couple of problems but ordering through Amazon has been very
helpful with any problems. My tinySA was promised to arrive in November
but instead it arrived a couple of days ago. In my case that was little
less than a month. I also ordered my nanoVNA through Amazon. It came
through a different seller and it took most of two months. I paid more
by ordering through Amazon but in the end I received good items and with
peace of mind during the wait.
Do you have tracking information yet? You can contact Amazon if you have
concerns.
73,
Bill? KU8H

Re: New tinySA control program for Windows
Hi Eirk
I'm just adding the changes you've made into my code (with some changes).
Just a word of caution, C and C++ is 99% case sensitive (100% in some cases), so you need to be very careful of that. Case is used and taken full advantage of a great deal out there in the C/C++ world, so getting the case wrong can introduce many bugs that might go undetected and/or difficult to find.
I'll add the scanraw command but at the moment not sure what the raw format is exactly, going to see what I can find.
