Re: [time-nuts] Loran C sounds
Majdi is correct. The budget report I saw showed that it was less to upgrade than to decommission. It still doesn't make sense to rely on only one system with the assumption that it won't break. I think in the future that shutting down these site will be deemed a bad idea.

Not so; Designs for H-field antennas for LORAN and GPS exist, and have been prototyped. eLORAN receivers perform on the order of unassisted GPS, and combined receivers (eLORAN+GPS) beat the accuracy of either. The problem with the -C shutdown is it means they having nearly finished the upgrades, will never run the new system. It's going to cost more to tear it down than finish the modernization.

Re: [time-nuts] Loran C sounds
What is going to happen if GPS has a problem, or if the US puts SA back on? Now the only backup for navigation is a sextant.

The Solar Dynamics Observatory launched this morning, on a mission to examine the fields and mass ejections that threaten satellites and power grids. They are delighted to be putting instruments in place after a prolonged quiet period so they can watch activity ramp up. The people who shut down non-satellite methods won't be in office at peak activity. 2. Its all about $$ because they are so easy to count. Decisions based on dollars don't require any technical background. People with empathy lose out to people who are focused on the dollars. (You folks with other currencies can substitute them for declining dollars. The principle is the same.) Should I automate or retain jobs? Let's see, which costs less per year? In dollars, that is, not human misery. Albert J. Bernstein wrote "Dinosaur Brains: Dealing with All Those Impossible People at Work" to explain how the most primitive brain of the three in our skulls sometimes / often gets the upper hand. Fatally attracted to female fatty deposits? Blame your dino brain and try to rein it in. Trying to deal with somebody shouting at you? You're watching a dino brain take over. Don't try to explain, the dino can't hear you unless what you say sounds threatening. Dealing with someone who is playing dominance games? Say hello to an ancient lizard and forget any attempt to reason with the person. Who plays dominance games? Almost any politician you care to name. So, no, don't think anything good is gonna happen. There's a reason why engineers are familiar with not having resources to do it right the first time. Darn, the soap box broke.
