There is a repeater on 145.670 (D-Star) in the Dallas area https://w5fc.org/tag/fsq/
It makes using XW-2A nearly impossible as it is right in the passband.
Who in the world thought it was a good idea to put a D-STAR repeater (simplex) in the middle of a satellite downlink passband?
Does this comply with any existing ARRL Band Plan, on other words is this a shared resource with D-Star? If so, I guess it's just tough luck and live with it. If not, perhaps someone from AMSAT can have a word with the Trustee?

XW-2A is the offender here as it operates outside the 200 kHz allocated in the bandplan for satellites, so there isn't any recourse. The satellite portion of the bandplan is 145.800 - 146.000 MHz (though amateur satellite transmissions are legal from 144 MHz - 146 MHz).
Note that the Texas VHF-FM Society Bandplan establishes 145.500 MHz - 145.800 MHz for simplex or experimental use (http://www.txvhffm.org/coordination/bandplan.php)

145.67 is in the Miscellaneous and experimental section not the satellite sub band. You can thank the Chinese for not using the satellite sub band.

Before casting blame it's worth remembering that these satellites fully conformed to the then IARU Region 3 band plan.
When the problem with the IARU Region 3 band plan came to light the Chinese Radio Sports Association (CRSA) / Chinese Radio Amateur Club (CRAC) proposed an Action on the IARU Administrative Council in 2015 to make accurate band plan information available, see https://amsat-uk.org/2015/10/21/iaru-region-3-conference/
IARU Region 3 have subsequently revised their band plan to specify the IARU agreed 145.800-146.000 MHz satellite allocation, although I can't see the 144.000-144.025 MHz IARU satellite allocation on IARU R-3's latest band plan issued September 2019, see http://www.iaru-r3.org/newsite/wp-content/files/R3-004%20IARU%20Region%203%2... The two satellite allocations are better shown on the IARU Region 2 band plan at https://www.iaru-r2.org/documents/explorer/files/Plan%20de%20bandas%20%7C%20...

Forget about the ARRL bandplan, it's the FCC rules that matter.
Code of Federal Regulations Title 47 Part 97.205b: "A repeater may receive and re-transmit only on the 10m and shorter wavelength frequency bands except the 28.0–29.5 MHz, 50.0–51.0 MHz, 144.0–144.5 MHz, 145.5–146.0 MHz, 222.00–222.15 MHz, 431.0–433.0 Mhz and 435.0–438.0 Mhz segments. "
So, 145.670 is flat out illegal for a repeater input or output.

This is not a repeater station, it's more like a packet node, and is appropriately located within the bandplan as an experimental activity.

Ah, you are right. Looking at the link, it is NOT a D-Star repeater as originally reported.

Seems like that might be more appropriately located at 145.01 - 145.09, but band plans aren't law.
Perhaps, if someone notified him/her, he/she might move the node.
