I recently ordered a TBS 5520 from Rick, and today I hooked it up to try, and have a couple questions.

First question is, when I ordered this receiver, from the specs, I saw that it had a separate input for non-USA terrestrial OTA, so I assumed that it would not do USA style ATSC.  However after installing the receiver, I ran the change-mode program for it, and it lists ATSC as an option. Is this receiver actually capable of ATSC??

Second question, since I already had G-17-Ku-V tuned with my PROF-7500, I ran the passthru to new 5520, and did a blind scan.  It locked about 19 transponders on the vertical side of this sat, ie virtually every transponder that showed up on the Crazyscan scan, except for 11740.  It looked like that transponder was about 40 MHz wide, which should be within the 45000 SR limit of the receiver.  When I'd click on that peak, Crazyscan would not show a constellation diagram for 11740, but instead would think for a while, then lock on the 11784 transponder, which is strange in itself because I had the search range on 3 MHz.  I then tried to lock the transponder on the PROF-7500, and it did not jump to 11784, but gave a constellation diagram on 11740 which looked like a completely uniformly filled circle.  From the constellation diagram with the PROF, I thought that perhaps 11740 is something like 32 APSK or higher, and I just don't have anywhere near the S/N to lock it.  I thought also that it might be DVB-S2x, since the scan showed steep sides.  The 5520 should be able to lock S2x, although perhaps the transponder had a higher SR than I estimated?  Or perhaps it's in some other unusual format?
   So my question, does anyone know what format the 11740 transponder is in?
    EDIT1:  Never mind on this question.  I finally did what I should have done before posting, ie looked in Lyngsat.  Apparently 11740 is a Hughesnet internet transponder, so no wonder I can't lock it.  But it's still strange that the 5520 just jumps to 11784 when trying to lock.
   

  I'm going to try a few more satellites to see what I can lock with this receiver, but eventually I may hook up an OTA antenna to the other port, and see if I can get Crazyscan to scan a spectrum in one of the terrestrial modes.

    I'm also curious whether anyone else is using a 5520, and how it is working for them.

EDIT2:  Oh, and I'm still using Crazyscan ver 1.0.2.148 .
Would I need a newer version of Crazyscan to access the full capability of this receiver???

ATSC not supported. See Si2183 specification
Test builds SreamReaderEx, CS & CS2

My TBS 6522 sometimes jumps to another signal if it is unable to lock the one originally specified and it commonly does not show the constellation.  If the SR is known, I find it helpful to not check the blind scan box and enter the SR directly.  I've found that many signals will then lock.

TBS 65xx also based on Si2183.

I played with the terrestrial/cable modes a bit.  Hooked up an OTA UHF antenna, and ran scans in DVB-C and DVB-T modes with Crazyscan-2.  Gives a nice wide-band spectrum of the UHF TV band.
ota-uhf.jpg  The 4 signals shown are channels 15, 17,24, and 44 in my area.  I'm blocked by hills with respect to other channels.  
  I tried down in the VHF band, where there are channel 3, 8, and 10.  Channels 3 and 10 are blocked by hills, so I didn't see them.  I did see what was probably channel 8, but the frequencies were off by about 3 MHz.  Ie about 173-183 instead of 180-186.  Not sure why that would be. 
   One thing I was curious about with this receiver is that the specs say it can do some QAM modes.
I remember a while back somewhere running into some QAM channels on satellite.  I can't remember where I saw them. If they happen to have been on Ku, I thought that perhaps I could use a DBS LNB to  receive the standard Ku band with a 450-950 IF freq, and then they might be receivable with the QAM mode on the 5520.  Probably wouldn't work, but I thought it might be fun playing with.

Is there any 64-bit software that will work with this tuner for macOS 10.14 Mojave or macOS 10.15 Catalina? If not this tuner, perhaps a different one?

Nope, never had any crashes with a Mac since I switched over 20 years ago, and no viruses, only Windoze Pee Cees... and that comment is off topic... since I asked a question related to satellite software...

I am guessing that apple doesn't think you need one, or at least they wouldn't recover their development
cost from it, so perhaps you could write your own such tool for MAC? Else I would find a machine to run Linux on.

Your only choice is to have a SAT>IP installation and use Elgato (geniatech) EyeTV or DVBViewer SAT>IP Viewer for macos. Or you could try the last (old) eyetv usb sat based on a TeVii S660 that was usb based.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
