Re: [Elecraft] This will effect pilots and Hams throughout the Western US

As a precaution for those in the affected area using the K3EXREF module, you might go to ref cal, wait for the asterisk to flash, hit A/B once and disconnect the GPS till the test is over. 73, Gary KA1J > On Fri, 2016-06-10 at 17:32 -0500, Jim Sheldon wrote: > > Actually it Is of concern to

Re: [Elecraft] This will effect pilots and Hams throughout the Western US

Disrupting isn’t the same as turning off! As was found during a test over here, a number of systems rely upon GPS time signals and can happily revert to their own internal clock for a while if the GPS is off — but not if the GPS signal is disrupted. The primary network clock for the main

I notice that you should see no interference unless you are several thousand feet above ground level from San Francisco to the Mexican Border in California and in extreme western Arizona or southern Nevada. Not a huge area for those of us on the earth itself. 73, Ron AC7AC -Original

Re: [Elecraft] This will effect pilots and Hams throughout the Western US

That's going to be difficult to answer without knowing just what effect these "events" will have on the signals received by the GPSDO's control receiver. If the GPS signals are "spoofed" the GPSDO could very well be driven off frequency, causing the K3EXREF to cause the radio's frequency to be

Re: [Elecraft] This will effect pilots and Hams throughout the Western US

If it is a concern to those with the K3EXREF, what happens to their frequency stability? Are they now off frequency? What is plan B if your K3EXREF reference fails? Does this even affect those? If it does, than I am sure it will affect most cell circuits as well. Just curious. On Fri, Jun

Whatever they're testing, it isn't commercial aircraft. The article seems to suggest that it's a jammer, and that makes some sense. They may be testing a system to detect intentionally distorted GPS. While it may affect a whole lot of stuff (like the cell phone network), an FAA Notice to

How times have changed. Back in 1997, when I was working as a contractor for my old company, Hughes Missile Systems (now Raytheon), I worked on implementing some jamming tests on the Tomahawk missile GPS. FWIW, we put the missile section on a wooden pedestal covered in RF absorber on top of

Re: [Elecraft] This will effect pilots and Hams throughout the Western US

Testing and practice all make sense but what isn't making sense about this is that we're disrupting GPS. Lots of stuff other than military rely on GPS and - just my humble opinion - It seems a little freaky that they are testing commercial aircraft. Wouldn't as valid a test simply be to turn off

Re: [Elecraft] This will effect pilots and Hams throughout the Western US

GPS and GLONASS use very similar frequencies. They should be equally easy to jam. Unless the jammer is narrowband, it might take out both. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 10, 2016, at 2:40 PM, a...@juno.com wrote: > > Many of the newer

When I was servicing shipboard electronics systems in the 90's, one of my regular "charges" as a civilian contractor was the Naval Hospital ship USNS Mercy ported in San Francisco, CA. I went to sea on her several times to check/calibrate nav systems, radars, direction finders, GPS gear, etc.
