Folks. I picked up this important 10 GHz note off the NEWSVHF Group reflector, started by Tom Frenaye K1KI, and amplified by Tom WA1MBA. As Tom says below, “We have some work to do.” Thanks to Tom and to Tom for alerting us.

Tom,
Thanks for sharing this.
We have to take some action.
Note that in this petition for ruling there is an intended set-aside of
5 MHz around 10,368 where supposedly there would be no operation of commercial gear. However, read it carefully.
1) There is an assumption that Amateur operation is predetermined and at specific locations, whereas much 10 GHz Amateur operation is sporadic and at unpredictable locations.
2) Furthermore, there is no limit on spurious emissions of the commercial gear which could interfere with those "protected"
frequencies, and
3) furthermore, amateur stations often leak LO frequency signals, which fall inside the 10 to 10.5 allocation but will possibly cause interference with this proposed commercial point-to-point use.
4) Also, because there is possibly 120 MHz channels, the avoidance of a
5 MHz channel could be ignored when using 120 MHz channels, thereby causing direct interference.
We have work to do.
