If I start up tinySA.exe, input a 10MHz signal and do a scan, it works fine.

If I just change the input to say 11MHz, and do a scan, it shows a lower level 10MHz signal but no 11MHz at all.
If I change the attenuator(like from 0 to -2) or do a different scan (like 20MHz instead of 50MHz) that "resets"
something and I see the new input freq.
If I leave the input freq alone but change amplitude or change the attenuator setting, it displays correctly.

Is the averaging set to off?
Please send a screenshot

Erik,
Hopefully the attachment is visible.. first time I tried this on this group...
I am doing Single sweeps, Avg set to Min so I do a few.
I start with a 10MHz signal, sweep it, then change it to 11MHz, sweep it several
times, 11MHz doesn't show up.
Then I change the attenuator setting and do sweeps.. Now 11MHz shows up.
Wierd.
I think I may need to get a Zero and start over...

ATTENTION!!!!!!

The setting "min" in Average means "minimum hold" !!!!!!!!!!!!!!!!!

Never use this unless you know what you are doing.
Always start with Averaging off

The "minimum hold" is automatically reset when you change anything in the scan parameters but NOT if you change only the input signal

OOPS.. sorry Erik.
Somehow MIN had got set as my default, even when I changed it, next time it kept coming back.
I thought yeah, ok Minimum averaging, why not..? doh..

Next question is about the automatic markers..
Sometimes they don't pick the strongest signal, sometimes they miss the "fundamental" big sig...

Now Nano(CH340G) is working fine..? BUFFERSIZE 32, Speed (in Settings) set to 0.

Speaking of which - are the Arduino Zero "clones" OK Erik? I was looking at one on eBay called the ...

I would search for Maple Mini. Lower cost and better performance, plus more I/O pins.

VA3NOI

In the newest tinySA.exe there are some settings on the settings panel related to the peak search algorithm

For that price... I'd consider the more powerful Photon boards.? I just found this even better priced version that matches the Tau price point you noted:

Here's the Photon Particle link from their store:

If for some reason you're stuck on Ardunio Uno boards there's a Sparkfun Redboard:

Or i'd consider an ESP32 clone, though I think those are on Aliexpress for cheap or maybe the RaspPi version more homegrown from Michigan:

I invested in an AtomicPi for starters... though am thinking I'm going to invest in one of those Photon boards since reads impressive.?

This should work

I bought these on Ali Express. A little more powerful than the stm32f103 based boards and about the same price.?

I bought the same item from a "US" seller (didn't want to wait - LOL).?
Thanks Eric.

I needed a maple mini board for another project and found this one to be a reliable clone.
