GPS spoofing noted

... and I have suggested several times that future Flex offerings consider the use of a receiver module that references all GNSS systems available (with flexibility to add more in future+).
And we can hold our collective breaths for a compact inertial package.

Hi Alex:

I can understand the concern for navigation but not so much how this affects Flex radios in any critical way. It might just be that I don't use my Flex for anything that requires ultra-critical timing and definitely my radio doesn't care where it is.

I don't have the GPSDO module. Calibrating with WWV on restart seems sufficient. Even if WWV were not available I wonder if I would notice anything. My old FT-1K or TS-820 were never sync'd to GPS and very rarely to WWV except maybe to calibrate the sound card I was using at the time.

What is it about the (seemingly speculative) article that would cause a Flex user concern?

The high-altitude EMPs from the 1st wave of a nuclear strike will take out all the Flex radios anyway. If your communications capability is that mission-critical get yourself a good KWM-2A.

21/3/2022: I think we have a good chance now (RUS/UKR) to see how backup/optional GNSSs m i g h t help: https://avia-pro.net/news/ssha-namereny-polnostyu-otklyuchit-gps-na-territorii-rossii and I hope Flex will incorporate that in the series 7000 radios - as I have mentioned. And it could well be that all the GNSSs will get plinked if things turn hot.

... as for EMPS, if one has gear well-stored/caged they will be able to operate subsequent to a nuclear attack, and even though I'm a great fan of KWM-2s -- they also contain semi-conductor junctions.
