First run original TinySA. Firmware 75, both waterfall modes work OK, self test passes.

Do you see a single colored line appear at the top of the screen at the start of the selftest?

Let me try to simulate display failure and see how it behaves

Hello All:

New tinySA user here, (I have a NanoVNA too).? My tinySA was from R&L, so should be real.?
I've had the unit for 3 weeks, worked well.? ?However, I have an odd issue when I load the latest SW, 1.1-74 or 75.?

Everything appears to work as expected, except that the Self Test behaves very strangely...
It does not progress to the test list, it just sits there...(usual freq / level display)?

If I press Self Test again, the display starts twitching and the unit freezes up.? ?
The twitching shows as an update to the frozen display... locked program loop??
I have to power down / up to resume operation...? ?
Is this just me, I have not seen this reported or commented upon??
I tried numerous older versions of SW that do work, and perform the self test... 1.1-72 works (but does give an ATTEN Fail on self check)

Another comment, like some others, the waterfall mode appears as just one thin line at the bottom of the display.?
I've seen suggestions about checking the LCD for shorts etc... I'm an engineer... but I'm not 100% convinced that the LCD shorts would cause all of these reports...?

Aside from these minor issues, I LOVE the tinySA (and VNA too)? It's not an HP, I have one of those too, BUT the HP doesn't fit in m y pocket!?

Best!

Steve?

Back in another life I picked up some used SMA adapters from one of the regular hamfest vendors that seemed to be in good shape for just a few dollars. I looked up one of the Amphenol parts later and they were around $80 new. I would be hard pressed to pay that much for hobby use but was happy to get a decent used one at a bargain price.

If you really want good connectors you have to buy where the industry buys and that is not from a ham source. You have to shell out? the price of the Tiny SA for one adapter.

I upgraded mine to 1.1-75 and it shows that firmware version.

Also corrects the modulation in FM Narrow and FM wide carrier frequencies.

I used IMSAI Guy's YouTube video and it worked perfectly.

These are genuine?

Yes, Zeenko is the store of Hugen who manufactures all genuine tinySA

Any of the Asian connector will work up to 350Mhz without problems and whatever small impedance bumps or loss they have from 400Mhz to 1ghz is less than the problems in resolution that the analyzer has at the high input.

Most cheap connectors bought in the US are also made in China, so be careful. I have gotten junk from W5WSL some of his SMA-F adapters are so far mechanical out of spec they are hardly usable...but hey they were cheap.? If you really want good connectors you have to buy where the industry buys and that is not from a ham source. You have to shell out? the price of the Tiny SA for one adapter. Look at Pasternack, Grainger, or Newark for quality. Example a good SMA-F/ to SMA-M adaptor from Pasternack is $53 a piece and there is a reason for that.? https://www.pasternack.com/sma-male-sma-female-straight-adapter-pe9694-p.aspx
Having tested many different adapters Hams sell on the internet or flea markets and many of those sold on e-bay I found it a better deal to look at swap meets for commercial assemblies that have a bunch of SMA cables and bulkhead adapters that the telecom industry uses. Most of those assemblies go between $10 and $50 and many have a large amount of connectors inside. Many a times the sellers are happy to get rid of them because a) the average ham doesn't build anymore and b) they have no idea what to do with that stuff. Take it apart. If you get an assembly for $10 bucks and get even 2 adapters? or 2 bulkheads out of them you have your money back 10 fold.With all the 3.1Ghz equipment that will be hitting the flea markets and e-bay in the US there will be ample of quality parts available in the near future.

That said, I agree with Zack, the SMB connector is widely overlooked . It is perfectly good for non critical low power use and for test equipment up to 3Ghz and I have seen hams use them at 5.8ghz. I have ample of cables, adapters and attenuators for SMB and SMC that I use for various projects.

Zeenko store currently have tinysa for ?37 plus ?5 carriage which is about the cheapest available anywhere.

These are genuine?

They also sell the saa2N for a pretty good price, too.

Thank you, requested a refound and will re-order from zeenko store.
If only I had found this information before. Also pity I gave the seller 5 stars (like most others) for his fast shipping and cannot edit this an add a warning for others.

Please update wiki, that store is not listed as clone seller under:?https://tinysa.org/wiki/pmwiki.php?n=Main.Buying

As listed on the wiki page the seller tool-box store sells clones and you have indeed received a clone.

New FW release
Version V1.1-75
Changes:
- The error in the NFM and FWM carrier frequency has been corrected

It's a clone. I had identical issues

Hi Erik

Thank you for the very quick reply.

I was just doing so after also stumbling over the 'clones' thread. Got mine from Aliexpress (Seller: Tool-box Store) and so far it does not meet the 'clones' description. Price also is in the same range as what I found on hackaday.

Please post a picture of the screen of the failing selftest? (7 and 8, not the final selftest screen) and a photo of the backside of the housing of the tinySA

Hi Gang

Two days ago I received my tinySA. First thing I did after looking at the FM and 2m Ham-Band with the provided telescopic antenna, was a firmware upgrade. Unfortunately I didn't bother to note down the leveloffset and correction values. I tought this step was sort of optional.

So I flashed and and did a clearconfig to start of fresh.

But now some of the selftest keep constantly failing. I have attempted setting various leveloffset values after reading some threads here, and have also been playing with the correction values to try to understand what they exactly do. But I don't get the tests 7 and 8 to pass. 8 even stays on 'failed'. Also used two loop cables.

Any help appreciated.
-Beno?t / HB9EUE-

Will look into this.
Guess something went wrong somewhere during an update

I experienced the same thing, although I wasn't as sharp as Liam to track down the shift in
the carrier, but just noticed that the tinySA didn't produce a carrier on the assigned frequency
when either FM or FM Narrow was selected, and would produce a modulated carrier when
AM was selected.? I had the exact same conditions, having just upgraded the firmware to
1.1-74.
