My new TinySA Ultra arrived in the mail today, two weeks and two days from ordering on Nov. 30, 2022. Everything looks great! Screen is straight, nice and sharp. Touch works like it should. FW tinySA_v1.3-506-g8291e1e as received. I will leave it there for now while I check out most functions. All tests were good. I'm not into the microwave frequencies (yet) but it seems to scan there properly. Will eventually update to the latest firmware:??tinySA4_v1.3-563-g1da836e (unless something newer comes along in the meantime).
This was about the fastest shipment I've received from AliExpress and the Zeenko store in all the times I've ordered from them. I'm happy for that and will most likely place more orders from them in the future.
Thanks Erik and everyone involved in the production of these awesome, amazing products. I own two original TinySA 2.8" devices and two original NanoVNA-H4 devices as well. Going to keep them all for now, no intention of selling them any time soon.
Off to experiment and play with all my lovely toys...err test equipment -heh-. (I have set up several antennas, among other things (NVNA-H4), and have used the TSA 2.8" to check receive sensitivity and transmit signals on my ham radio gear.)
