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.

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.

Look at the attenuator level. Sometimes it stays at 30 with no signal present.?

My recently acquired (and on close inspection, genuine) TinySA with 1.1-74 firmware exhibits this behaviour. I discovered this by chance with my VX-7R, having found the carrier would disappear when I selected FM modulation, but not with AM. I happened to use the channel search function and found where the carrier is going.?

On low output with FM narrow or FM wide modulation, the carrier shifts up 160kHz while the displayed frequency remains as selected. With AM the carrier remains correctly on the selected frequency:


Low output, no modulation


Low output, 1kHz AM


Low output, 1kHz NFM


Low output, 1kHz WFM

On high output with FM narrow or FM wide modulation, the carrier shifts up 80kHz while the displayed frequency remains as selected:


High output, no modulation


High output, 1kHz NFM


High output, 1kHz WFM

The TinySA was delivered with a few days ago with firmware 1.1-12 (or thereabouts) and if my memory serves, it did not then exhibit this behaviour. Maybe someone can do a sanity check and see if this is indeed a bug.

Regards,

Liam

I can occasionally connect to my Win10 PC although never when RBW is selected other than AUTO.? When it does connect the default settings noise floor is sometimes -58 dB and sometimes -80 dB.? Weird.? So I tried to connect to my laptop Win7 device.? The program does not ally me to select a port number (as it does in the Win10 desktop) and only displays NONE.? So no connection possible.? I'm guessing I am missing something in a setup or whatever.? Am I destined to use the small screen and save with my cellphone camera?

And when you need a SMA bullet, I recommend this style with a knurled center section: ebay # 202670005403

Two reasons I can think of:

The pintails will wear out or break long before the savers.

Most people will find themselves changing the pigtails often for one reason or another.

Instead of these savers, why not use little SMA pigtails (6" or so)?

It all depends on what your trying to do and what your trying to measure. As has been already mentioned, if you're just trying to measure relative levels and not absolute values you could just?use the tinySA antenna.

Only if you are measuring relative levels of signals in a narrow band. As soon you have signal spread over 3 harmonics, you mast have physical tap
