Anyway, I have not yet managed to measure with dynamics greater than 60dB and the nanoVNA if it has it at frequencies below 300MHz, so I do not have a pressing need for this tracking generator to be

Thanks for the suggestion John. I use one of those SAW transmitter modules, but it is built to be CW modulated, meaning all or nothing. The modulation input drives the base of a transistor through a

Can both of you that have the failing waterfall try to do a screengrab using tinySA-App.exe? If the screengrab works there is at least one possible problem

Screenshots work? This can related to read error from LCD, TintSA CPU not have enouth memory for store all waterfall data, it just copy line down. Need check SPI SDI line from display to CPU

Hi all The same in black. I m trying different firmware and nothing change.? Good year 2021. Envoyé par myMail pour iOS

If you use one of those inexpensive saw module transmitters as the oscillator, you can use the modulation input instead setting it fixed to the on rail install a potentiometer. This will permit you to

Thanks for the suggestion Erik. I will check and report. What I did observe was that changing the RBW varied the level delivered by the tracking generator. It was caused because the frequency of the

Thanks Eric, that worked a treat! Using a 20dB attenuator, I measured 29.0dB at 280MhZ on the SA.? When to High port, switched mode input, and then followed your guidance below to adjust it to the

Does anyone have a reliable source for inexpensive couplers? I’m a disabled vet and I have to watch my pennies

IF you do a measurement with tracing generator you better set the RBW to manual and maximum Can you check if this removes the artifacts? ------------------------------------------ For more info on the

Hi again, everybody. I have built a tracking generator using a 433.9MHz transmitter as LO. The out of the 1st LO of the Tiny not enabled (30dB lower approximately) is amplified by a MAR-8A and is used

Just a reminder. You can pay with PayPal in the Zeenko store on Alibaba. Just contact the contact person of the Zeenko shop (Maggie) and ask how to do the payment using

Ordered my TinySA from Alibaba on 9/15 and received 9/24 in Texas.

Oh thank you so much for the information! I missed that somewhere about the various options with the waterfall. Thank you so much for all the work you have put into this project! Roy WA0YMH

Hi, The covid has disrupted so much. A real surprise is when things arrive in a couple of days or so! 2020 should be named the year without a year! Stay safe. 73, Bill KU8H "John"

After enabling the waterfall a waterfall taking about 30% of the screen appears. Tapping again switches to the big waterfall taking about 60% of the screen. Tapping a third time disables the

I wonder if the global pandemic and Christmas flood of packages has delayed your shipment. I ordered mine wisely(?) 8 Dec, Canada Post is aware it is coming, all the news I have so far is that it on

Forgive me for taking your time but if I might ask, what is the "big waterfall"? I thought that that there was just one waterfall? Thanks, Roy WA0YMH

Zeenko store is the store from Hugen so guaranteed to be reliable. Aliexpress shipping adds complexity -- ------------------------------------------ For more info on the tinySA go to

About 6 % of my AliExpress orders end in the “dispute" process. I don’t have more detailed break-down numbers, but this is a mix of shipment/customs issues (like apparently yours), destruction in
