Re: Reload FW_White screen
Thanks Erik, just loaded the latest firmware 1.0-44 and all is good.
I tried to run it on the tiny sa windows 10 program, but very intermittent no worries all ok...

Re: Reload FW_White screen
Yes, just like the nanoVNA, same two pins to connect
switch off the tinySA
Open the case
Connect BOOT0 with VDD
switch on the tinysa
wait 5 seconds
remove the connection
update firmware

Hi Erik
My fault!
I tried to upload the firmware, using the usual tool,but found the fw was not readable...
So I simply made it readable - 'now there's the problem'
It then did something and now my dear NanoSA has a white screen only...
Can one reboot it like the old NanoVNA can, by shorting the two pins - hope so!
How can I restore my NanoSA back to normality? Help

Re: Tiny SA arrived today.
Left it on until the battery indicator went red, less the 3v ?I then put it on charge. Will only charge to 3.4v and battery indicator 1/4 full. Has been on charge over 2 hours.?

Re: Tiny SA arrived today.
Does not display 4.2 so maybe charging IC

Re: Tiny SA arrived today.
Same here, huge kudos to Erik, Hugen and Maggie
Ordered on Alibaba on July 23
Delivered in Boston: Aug 5
First test: after the initial setup steps, output of my Elecraft XG3 at -73 db into tinySA, 28.2 MHz peak, reading -73 db almost spot on

It is currently not possible to place a marker on a stored trace. Is it something that should be possible

I have never done this FM deviation measurement but it is possible to see the carrier dip.
So I guess you can tune the depth of the modulation to get the first dip using a tone of 2kHz.
Any other views?
A quick estimate of FM deviation using a spectrum analyzer that my former lab used was: 1). Capture the unkeyed carrier [Display->Store Trace], 2). Key the carrier and measure the deviation between traces using markers.? I just tried the procedure using the tinySA and it was surprising accurate.? Normally I would place each marker at a point on a horizontal graticule where both waveforms cross, but I couldn't figure out a way to place a marker on the stored waveform.? Fortunately the carrier was straight, up and down, where I needed to make my measurement so I could eyeball placement of marker 2.? Here are my results: ? 144MHz@10kHz-FM? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 144MHz@20kHz-FM?? ? ?144.012 - 144.003 ~= 10kHz? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?144.023 - 144.003 = 20kHz ? ?  ? ? ? ? ??  ? ?

Re: Tiny SA arrived today.
WHen you switch on the tinySA, does it work?
If you unplug the USB does it switch of immediately or does it work for some time?

Re: Tiny SA arrived today.
The red led is still on after 12 hours of charging. Indicator says 3.3v and is 1/4 full

Re: Tiny SA arrived today.
Alibaba
Can’t get into account. Tried to reset password, new password does not meet standards but standards are not listed.
Guess I will toss it and call it a bad day.

Re: Tiny SA arrived today.
Contact the seller. They will tell you what to do.
If you did buy from one to the official stores of Hugen you will be surprised by his customer care!!!

Yes, ?8 is “handling charge” the rest is vat.
