Some of the new mini-pcs have USB ports that are not powered.

Another common source for RF noise in these VHF frequency ranges, is a bad cable-TV setup somewhere.
I seem to recall a particular problem was cable channel 52(?) coming up in the 2 meter band.

When I search for a zk10 I get all kinds off stuff also. But when I search on zk10d I get the chip. Be adware that the results differ from country to country.?

I tried the link also, message "oeps does not deliver in your country".

Look at the price difference.

Link definitely works in Australia, but I then tried changing the delivery address to my daughters address in USA Ma, and it then said "Page not found"
You might need to have a conversation with your President.

Re: Hunting Spurious Emission at 154 MHz
My experience agrees with yours re MATV. I work in large stadiums, and it is unusual to monitor TV channels that should not be there "Over the Air" and indeed are not measurable when moving to different parts of the stadium.
It is currently especially prevalent as large screen MATV's in public areas are being replaced with IPTVs and little care is taken of the unterminated MATV coax, it's often just shoved back into the wall. In a large stadium it can be a two year project to migrate 100's of TV's add all the switches run CAT 6, all the time there are more and more unterminated Coax.
the dead giveaway is seeing Channel 27 with a 7MHz signal (Australia uses 7MHz TV channels) but 27 was never used Over the Air as it is 519-526MHz and Two-way Land Mobile Radios are 450-520MHz. (520-526MHz is really a guard band).

I doubt you can use the BGA2817 instead. They have a different pinout, and the powering method is not the same either. In the GHz frequency range, any extra wiring can cause unpredictable results, so I would prefer to buy a proper chip and avoid the risk.

Don't forget there is a new $100 customs processing fee for all packages coming from overseas.? This is in addition to any tariffs.

What can I say? For me it popped up a tiny square "blue smoke" container that amplifies radio signals. Maybe try ZK10D. The point was that a quick search will solve the problem more quickly than a complaint posted to an internet group. Links posted by someone often don't work as intended for others for various reasons. But you don't need to fret about the reasons to find what you are looking for.

So.. I received LNA's (BGA2817), but it turns out i need Zeenko's ZK10D. They are not listed on theirs aliexpress store. I wrote them, waiting for answer.
Is there any way to bodge BGA2817 in there? Or maybe order some other part, that is easier to source?

Is "Brightness" only on the bigger models? I don't see "Brightness" on the TinySA Basic.
Brilliant device. I used to have an HP141T with all the band plugins and then replaced it with a Rigol (up to 1.5Ghz with TG version). I'm using the Basic as a "panadaptor" at 68.33 MHz on an FT-817ND just with a J310 FET buffer in the radio. I might get another for my FT910H. The spectrum is inverted, but you get used to that!
