Hello Robert -

    So far the only issue of which I am awarre that involved the Galileo
system is that an Indianapolis ATV repeater had to move it's output
frequency so that the Indianapolis Sheriff's Department asset management
system would not receive interference. As it turns out the manufacturer of
that system chose to use Galileo instead of GPS. We are after all, secondary
users in that band and moving the output frequency of the ATV repeater
seemed like a very simple accommodation.

Bound to happen more and more as available spectrum get rare. I think we have only seen the beginning.  Remember, Part 18 ISM (Industrial, Scientific, and Medical) devices have priority, though the unlicensed stuff like wireless phone extensions and such may not interfere with our use.  If Amazon opens up there, the noise level will come up substantially for weak signal work.  Is this why Amazon paid ham radio’s internet address custodians millions to get our address blocks?

 

My neighbor uses analog FM wireless 5.1 channel TV speakers on that band which are not happy (they shut down while I transmit with 20 watts over 100 feet from them), but that type of unlicensed use is not protected.  I recall the utility companies make use of the band for remote reading utility meters as well.

 

  I operate on 902 -927 FM with 2 Motorola radios including 1 Spectra base station and a MTX-9000 and 2 Alinco DJ-G29 transceivers.  Nice band for that use. Not much we can do to prevent this, I fear.  And isn’t 1296 MHz is under siege from the Galileo GPS system as well.

Amazon Sidewalk wants to operate in the Amateur 900 MHz band.

Anyone see this one coming?  I didn't (and I operate SSB/CW in this band).

Are you familiar with Amazon Sidewalk ? This item caught my eye as it mentioned the 900 MHz amateur radio band.

At its Alexa event on Wednesday, Amazon announced a new low-bandwidth network called Amazon Sidewalk that could extend the range at which you can control your devices beyond what Bluetooth and Wi-Fi currently allow. 

 

Amazon Sidewalk taps the 900MHz band of the radio spectrum -- typically used for amateur radio -- to extend the distance at which you can control your smart home devices, Dave Limp, senior vice president of devices and services said during the event.
