I'm joining the discussion late, but: as a confirmed radio listener, there's at least one radio in every room of my house, and several are am/fm portables. The Tivoliaudio PAL is a portable AM/FM that sounds decent & can be carried around if needed, like out to my driveway when I have to work on the cars. The crank-up emergency radio is stored in the shed, probably has AM band since I bought it many years ago, late in 1989. So far it has prevented the next big quake...
@RobertReavis- You make a great point that others have already made to me. I do need an emergency radio handy and have been planning to get one for years. Now that I have been chastised by several readers, I will make it a priority. Even so, though, the hand crank emergency radio I will be getting would probably not have been a great solution to this problem.
I still miss my 9 transistor Sylvania AM radio. It was too expensive for my parents to buy, but I actually won it at my father's union Christmas party. I thought I had gone to heaven!
That radio worked great. I remember laying in bed listening to those "clear channel" stations that were hundreds of miles away.
That radio got thrown out when my mother moved, even though it still worked & looked great. It was old.
I did however recently snag an old Westinghouse 6 transistor that was abandoned by a tennant of mine.
Although I'm a Rockies fan currently living in the Bay Area, I was also captivated by the Giants run though the post-season. lListening to the games on my late commute home, I had a choice of the local KNBR feed (Kruk and Kuip are fabulous to listen to, even when you are a fan of the opposing team) or either home feed or the national feed on the XM system in my car. As an engineer, I just had to benchmark the latency difference (at least 15 seconds of delay on the satellite feed, as I recall). At one point I arrived home during a crucial at-bat, and it was apparent that the DirecTV satellite feed was even further behind than the satellite radio feed. It didn't matter, however, because as soon as I walked in the door my wife paused the DVR, we took care of some quick dinner preparations, then picked up the game from where we had been. No reason to miss a pitch! (And we could catch back up during commercials.)
So many technologies, so many choices...
I have managed to hang onto a couple of plain old transistor radios that work. We're in tornado and ice country and it has paid off a couple of times. A hint for finding AM radios is to take a look at the emergency/travel radios that a nmber of places sell, including the Red Cross.
We've also resisted doing away with the POTS line for similar reasons. Our power was off for a full week one time and Internet service was down for 10 days. Cell service was problematic as one of the nearby cell towers was down (literally) as well.
Beyond that, we do have a generator that can run the essentials in the house such as the gas furnace blower, sump pump and lights and my ham radio station has Gel-cells enough to run for several days.
Reminds me of a few years ago when the Red Sox were in the hunt and I had to be out and about for the evening (shuttling kids around) and was going to miss the game. I tried to find a FM station broadcasting the game but was not able (I wanted the clarity of FM), I gave up and switch the car radio to AM and found one station and then a better one later on! Sometimes the old ways just work! Thanks for the memories.
Great story Dylan. I was overseas during the Giants run this year so an AM radio wasn't much use. My iPhone app did the trick, though, even if the games started after 2AM local time. In an odd kind of way it brought me back to my days as a youngster in Boston, falling asleep with a transistor radio on under my pillow when the Sox were on their West Coast swings. I just wished the iPhone battery lasted as long as the transistor radio used to!
If you and your brother were betting types you could have made a fortune! ("Twenty bucks says the batter is going to ground out to short.")
A third moral is that you should always keep a small AM radio on hand in the event of a unscheduled disaster (hurricane, tornado, earthquake, snowstorm, flood)in case the modern and complex communications systems fail. A CB type walkie-talkie would also be useful. Keep the batteries fresh. Same concept as retaining a twisted pair corded telephone than runs off the central office battery for when AC power and cell service or VOIP fail.
@Danngis.Liu- I might be wrong, but I think the FCC-mandated delay is only a few seconds. The meat of the delay, as I understand it, has to do with the way the signal is relayed...
@dsthil- thanks for the tip. I will check it out....
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
