For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro music was by Michael Jackson. The outro music was by Pentatonix.
More info about the music is here.


Both Paul and Glenn were in the studio today.


Glenn recently switched to IOS 12, the operating system for Apple’s mobile devices, So far, he likes it but found a problem with the ringtones. The ringtones reverted to the default tones that came with the iPhone, except in a couple of instances. He said this has been a problem with previous IOS updates, but it hasn’t affected him until now.

Paul said that in the early days of cell phones there was quite a market in the sale of ringtones and the companies made it deliberately difficult to create your own.

He went on to distinguish the difference between ringtones and the ringing sound the phone company provides. There are different ringing sounds, like 2 quick rings, that a company such as Verizon can provide you for a fee. There is also an optional sound (e.g. music) that a caller hears before those being called answer the phone, but implementing that is not straightforward, Paul said.

To fix the ringtone problem, Paul did some googling and found some advice that said “just plug your phone in to iTunes and resynch it, that’s supposed to fix it”.

Paul talked about spooky sounds for Halloween. There’s a link at the top of this page to what he found. To find more sounds, go to youtube.com and put in [to search] ‘spooky music sound track’, he said.

Paul was given a piece of equipment that was state of the art 15 years ago. It’s a Nikon LD40 slide scanner that takes 35mm slides and negatives for digitizing. Nikon stopped making the scanner, the drivers and software for it a long time ago.

He talked a bit about how it scans in the primary colors and then recombines them in the final image. He said there is a huge section about color in Wikipedia, just search for ‘color’.

One of the colors it scans is in the infrared because it’s strongly absorbed by surface defects like scratches. Using this extra information, the software can later subtract the artifacts that got onto the slide’s surface.

Paul used a Linux driver with the scanner and it worked to a degree. It did the basic scan but couldn’t take advantage of the advanced features like the infrared information to remove dust & scratches. You can use photo editing software like Photo Shop to remove the defects manually but it’s tedious, he said.

However, there are scanning software packages that may help you out. He mentioned Silverfast and VueScan for the PC & Mac, See the links at the top. The packages are not free but they have demo versions. The demos produce images have the words ‘demo version’, but you can at least judge if the software does a good job. If you like it you can buy a license key to unlock it for about $100.

Paul said he likes VueScan because, once you have the key, it will talk to any scanner. Silverfast is much more advanced & professional but it will work only with the hardware you register for.

Paul said he found some slide scanners on Amazon, and one that doesn’t involve a computer — it scans the slide and saves the image directly into a USB drive. See the link at the top.

He also suggested going to a second hand store and getting a slide projector. While projecting the image from the slide on a screen, you can use a [digital] camera on a tripod to take its picture.

Also, there is a scanner for $179 that will digitize your 8mm or 16mm movies. Then you can use open source software to remove blurring, jittering and grain.

Colter called. He has a Mac desktop computer running the Mojave operating system. He can’t get it to go completely asleep and it keeps waking up on its own.
– There is a facility called ‘wake on LAN’. If there is something on the network that needs to talk to it, then it can wake up. Also, it’s possible the Mac is misinterpreting such messages when they’re not even meant for it. To test this, turn the wi-fi off and unplug the Ethernet.
– Check for consistency in its waking up. Is it done in a cycle. This may give you a clue.
– Check the power options under ‘Settings’.
– Go up to the Apple logo [on the screen] and check for updates.
– Also try unplugging the keyboard, in case there’s something wrong with it. <It may be sending a signal to the Mac as if a key had been pressed.> Similarly, check the mouse.
– Or it may be waking up to do a Timemachine backup. To test this, “Unplug your Timemachine”.
– Some peripheral may be trying to talk to the Mac. Unplug one thing at a time to see if the problem goes away

Douglas called to say that his machine has a similar problem with waking up. It can happen when the refrigerator comes on or a truck drives by.
– It can be due to EMF spikes due to a bad voltage regulator.
– A surge protector will not correct the problem, but a UPS (uninterruptible power supply) will “take care of what you describe”.

The reason Douglas called had to do with his cell phone getting text (txt) messages. He had upgraded to the iPhone 5 from a 4. He had been exchanging messages with a friend but then wouldn’t receive any for a while. Suddenly, there would be a bunch of unread messages waiting for him.
– Are these green messages or blue, Paul asked. Douglas said he gets both. Blue means the message was delivered via the internet, not thru the cellular service via SMS (short message service).
– Glenn had seen a similar problem with a friend’s phone when he helped her change cell phone providers. He had to go to ‘Settings’ -> ‘Messages’ and turn iMessage back on.
– Paul told Douglas to look on the older iPhone 4 to see if any of the messages ended up there. It can receive messages even though it no longer has a SIM card in it. If it’s still connected to the internet, it can still receive iMessages.
– Try texting with that friend in the same room. You may just have a weak internet connection. Or use the app called Speed Test. Don’t just depend on the number of bars to tell you the connection is good.
– Back up your phone to iTunes and then reload and refresh the operating system. Paul said he’s so many problem corrected with this procedure. So, back up, then press ‘restore’ to wipe the phone clean, then reload the latest operating system, and finally restore the data you just backed up.
– Paul asked that listeners call in if they have suggestions
– As a last resort, use a messaging app other than iMessage — Whatsapp, for instance.

Continuing, Paul asked what phone company he uses. Douglas said it’s H2O. That made Paul recall problems Glenn had with that company. He then suggested turning off MMS (Multi Media Service). If the friend tries to send Douglas a picture and “it doesn’t go with iMassage” it will try to use a data service over the cellular service called Multi Media Service which doesn’t work with H2O on the iPhone. Under ‘Settings’ -> ‘Messages’ turn off MMS

Nick, an electrical engineer, called about the symptoms Douglas experienced when the refrigerator came on or a truck drove by. Nick said its a sign of something that should be investigated and corrected because it’s highly likely the wiring in the building (the power wiring) has loose or inadequate connections. It’s a fire hazard, he warned.

Buzz, the KVMR engineer, came into the studio to offer a tip in finding the faulty wiring. He said, take an old AM radio and tune it to a blank spot on the dial where there is no station broadcasting. Then walk around the house waiting for the phenomenon to occur. When it happens, you’ll hear a bunch of static on the radio. Wander around to where the static is the loudest. Then take apart the AC outlets in the wall or tighten the joint in the circuit breaker panel. Wherever the static is the loudest is where the [electrical] arc is happening. If there is no static, chances are the problem is not in your house, Buzz said.

Nick said all of this may be beyond the average person’s ability but this is stuff that can hurt you and light your building on fire. Get it checked out.

The disclaimer:
The views and opinions expressed on KVMR are those of the speaker only and not necessarily those of KVMR management, staff or underwriters.

Finally, Paul added, powder fire extinguishers are fairly inexpensive. The last thing you want all over an electrical fire is a bunch of conductive liquid.
