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"

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).

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!

Re: What accessories do I need for a TinySA Ultra?
A GOOD PRACTICE:? Whenever I pick up the end of a coaxial cable, I always hold a finger across the end "shorting" the center conductor to the backshell before connecting it to anything.? Doesn't matter if the coax is connected to an outside antenna or laying on the bench.?
Most of the time I don't get any response.? But occasionally I get just a "bit" (***) of a surprise.? You just might get more of a surprise if the coax is connected to an outside antenna in a windstorm, rain, or snow!?? In either case, I've just saved the piece of equipment I was going to connect the coax to.

Re: Hunting Spurious Emission at 154 MHz
Some years ago I helped chase down an interferer whose signal was drifting through the input frequency ranges of a bunch of 2-meter ham repeaters in our area.? It came and went, and when present had a particular pulsing pattern.
?
The local ARRL OO had managed to find its general location (to within a city block or two) but investigation of the usual suspects (TV-antenna amplifiers that might have started oscillating) hadn't found it.? I brought a spectrum analyzer and "tape measure" Yagi antenna to the party to help the direction-finding.
?
We were able to DF the signal to a small portion of an apartment complex.? We spoke politely to the local residents, and one guy near the apparent location offered to let us check his apartment.? The interference was strong, so we asked for permission to start turning off his computer gear.? Bingo!? When we unplugged the Ethernet switch, the noise completely went away.? Turn it back on, and the interference reappeared, with a pulsing pattern which exactly matched the flashing of the "traffic" lights on the switch.
?
My best guess is that the noise was a harmonic of the on-board crystal oscillator (which apparently wasn't all that stable) and that some failure of a filtering component in the switch was allowing the harmonic to leak out into the Ethernet and power wiring... "turning the whole house into a giant TV antenna" as the ads used to say.
?
I offered to trade the noisy Ethernet switch for a spare I had at home (one with more ports).? The owner agreed, we made the exchange, and the noise was gone for good.
?
Another common source for RF noise in these VHF frequency ranges, is a bad cable-TV setup somewhere.? Most cable-TV plants "re-use" over-the-air frequencies for on-cable channels.? If a cable system's wiring isn't "tight" (all segments properly shielded, and either fed to TVs or terminated in 75-ohm dummy loads) this RF can sneak out and radiate over-the-air, causing all sorts of interference.

Add to this list people who routinely mix up "B" for bytes and "b" for bits, especially in the networking part of the computer world.
