Signal Strength on Radio Controlled Clock

Why not have RF strength meter on Radio Controlled Clock so you can find the best position to mount?

As it is, you have little way of knowing, except locating the clock in one position or another and seeing if it gets the time in a day or two.  And then you may wonder if your clock is defective, the batteries bad, or some other problem.

My old LaCrosse clock had problems, the batteries had once gone bad and I figured the terminals were corroded, and that might have been the reason why, in the end (after 5 years) it wouldn't start even with fresh batteries.

I got another LaCrosse clock figuring it had improved.  (The old one also had weird daylight savings bug where it would switch back and forth between correct time and previous time during the day of the daylight savings change…then be correct after that.)

Indeed, unlike the old clock which sometimes took many days to get the time signal, and I often wondered if I had done the settings wrong and started all over, the new clock came on and had the atomic clock time reliably from day one.

But it has a different problem: the batteries last about a month!

I figure what is going on is that since the clock can't get the time easily every day, it keeps on trying.  Unlike the old clock, which would only try at midnight, 2am, and 4am, or something like that, the new clock just keeps trying.  And that wears out the batteries fast.

That would be consistent with the other clock not getting time signal reliably.

So I've moved the clock to a new location and will see.  But it's only 5ft from the previous location, so no telling how it will work.  I could move the clock to a different wall of the house.  But that would mean guests wouldn't be able to read it from the couch.
