Ratboy, have you tried on the roof of your apartment? Could help identifying the RFI. If you’re fairly clear on the roof, then possibly someone in the complex is the issue. Walk the halls with the radio, see where it’s the strongest.
New Malahit DSP2 multi band

How's it going with the DSP2? Am still tempted to order one.
I'm happy with mine and there are plenty of reviews on them.
But if you wait, a newer better one will come out for sure.

Have seen the DSP3. I like the design of the DSP2 better. How is the waterfall display? Is it nice and smooth when rotating through the frequencies? Or choppy?
I may be wrong, but I was under the impression the DSP3 was an earlier model.
It's certainly cheaper.
The waterfall on mine is quite smooth, but that can be adjusted in the settings.
I have a Icom IC-R8600 and on the same antenna, the performance of the DSP2 is comparable.
I think the filtering is actually better.
If you do buy one, get some SMA male to SMA female adaptors and leave them on the radio.
I you swap antennas as much as I have you will need them to prevent waring out the ones on the radio.

Oh yeah, it doesn't matter much what kind of antenna I put on it, it just is horrible. I had an old loop antenna, don't remember what it was called, and it worked pretty great when I lived in my house. In '17, I moved to an apartment, and WOW, the RFI is amazingly bad. I bought another couple of them and they are of no help. I bought one of those RFI eliminator things and it was almost totally useless.
I work at a place that has a NOC in it, and it's almost as bad as my apartment is. The hash is worse at VHF Hi and up, but slightly less on HF. At either location, FM Broadcast is what you can get decently, along with VHF Air, rail, etc.
It's everywhere, some places it's stronger, but it's at least a 20 over S9 and in some areas, it's like 50 over. Sounds like the worst flourescent light buzz times 10. The light above my sink not only throws terrible RFI, it buzzes audibly with the same buzz, so I never use it. Doesn't matter anyway, the other RFI sources are wiping everything out anyway.
The DSP3 is the earlier model. I don't really understand the whole model numbering thing they are doing with these radios. The DSP3 isn't bad, actually, but the DSP2 is a lot better. The previous ones are really pretty sad in one way or another.
Interesting to hear. Thanks.
How’s it going with the DSP2 these days? About ready to order one.
just to verify, it’s this one, correct?

NO -- the DSP-3 is the name of LATEST Russian receiver. The China clone being sold on Ali and elsewhere is the DSP-2 which is the
earlier version of the Russian Malachite by Malahiteam. Let's not get things confused. The earlier DSP-2 uses firmware 2.40 which is
or was as of the time I write this, the latest fimware for the EARLIER receiver. I have not seen the DSP-3 being sold on the China market.
I looked at Malachite web site. Shows pre order for the DSP3. With embargos against russia, doubt they will build it until most countries lift the embargo. Was just asking folks with the DSP2 how things were going so far.
Mine is doing fine. Zero issues of any real kind. The noise from the display is a little annoying, but that only really happens on the whip. An external antenna, like a mag mount CB antenna, works pretty great. I went train watching and tuned around and heard all kinds of N. American and European CB skip very well. I put a friend's 20M mag mount on the roof and it was blasting in, 15Mhz broadcasters were VG too. The battery life is good, and the audio is about as good as something that size could be. If I could change anything about the size or whatever, it would be to make the format horizontal, and make the display bigger.

Of course there is the original Russian-made DSP2 as well (I have one of these) and it's a decent bit of kit. For me it only has one issue but this is one that wouldn't affect US users since airband in the USA does not use 8.33 kHz spacing as far as I am aware.

Radioddity currently has a the DSP2 on sale at AliExpress prices during their Anniversary Sale. It's shipped from Las Vegas and you get their incredibly responsive customer support. They ship fast, two day delivery to central Kalifornia.
I'll add that I'm an old HF DX snob. My references are a two R390As paried in diversity or with a Sherwood SE-3, Collins HF-2050, a John Thorpe configured AR7030 Plus with Kiwa mods, AR5000 with a DSP-599ZX, Airspy HF+ Discovery along with a Lowe HF-150 with Kiwa mods and a couple of Belkas for patio use. I've only had the DSP2 for one hectic week with limited use due to time constraints. If you're familiar with SDR's and willing to tweak the settings it's a superb receiver.
