Amazing for $60 - It IS in production. Time Owned: 3 to 6 months.
Ordered from R&L Electronics - US dealer. Arrived quickly. Amazing device and very useful for finding RFI. It is now part of my go bag. Will buy the Ultra version when it come back in stock.

TinySA Ultra Time Owned: 0 to 3 months.
Review of the "Ultra" model:

Picked this little gem up at R&L a week or so ago.
WOW!
Add a -50db RF sampler(homebrew) and you can
see for yourself how nasty those $20 V/UHF handhelds
from China are.
Is it "lab grade"? - of course not! But compares well
with my Siglent SA($1400 vs $130).
Add a NanoVNA H4 and a low cost 100Mhz scope and you
will *almost* have all you need to play!
BTW-- R&L is in the USA and ships fast.
----------EDIT-------------
Forgot this. Add the TinySA Saver software(Windoze and Linux) and it makes life even better.

Fantastic Tool - mind-blowing good! Time Owned: 6 to 12 months.
This little unit is amazing. You can check for undesired harmonics, run an antenna pattern, check for IMD and check the linearity of amps, check out the effectiveness of filters on harmonic suppression and look for potential sources of interference all in a device about the size of a deck of playing cards!

Next to the nanoVNA this is the most useful piece of test equipment you can buy. The fact that it is only $49 is mind-blowing!

Very good measurements Time Owned: 0 to 3 months.
I connected this unit to an Agilent 8648A Signal Generator to check it's performance. The frequency was very close, even at over 900 MHz. The levels ran about 1-1.5 dB low (within 1 dB on low range) but that's still pretty good for a pocket instrument for that price. It does have a strange spur displayed in the high range that's -35 dB of the carrier. When the carrier is reduced, the spur drops as well, until it falls below the noise floor. On the low range I didn't observe one.
I found out later there is a spur rejection feature but I have not tried that yet. Overall it's a great product, though the screen would be better if a bit larger. I suggest every ham purchase one.

Surprisingly accurate spectrum analyzer and signal generator. Time Owned: 0 to 3 months.
A spectrum analyzer and signal generator that works as advertised! The signal generator has AM and FM modulation, 70dB 1dB step attenuator, and will work as a sweep generator. The spectrum analyzer is spur free , exhibiting a noise floor of -90 dBm sweeping 150Khz to 350MHz with a RBW of 621KHz.

I measured the amplitude accuracy of the spectrum analyzer and the signal generator, both were within +/-1 dB from 150 KHz to 350 MHz. The signal generator frequency was set at 14.300 MHz and the measured result was within 5Hz. Measured power levels in the "high" range from 240 to 960 were within 4dB.

The TinySA was tested with a Fluke 6060B, a Siglent SSA-3021X, a B&K 1851 frequency counter and Leo Bodners frequency standard.

The TinySA was ordered from RandL electronics and arrived promptly.

This is a five star product at the 49 buck price. The down side is the small screen is tough to read and work with. A four inch screen would be most welcome.
