[amsat-bb] D-Star Interference to XW-2A Downlink

[jim at k6ccc.org]

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.

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?
