Josh, W0HC – Whoa! Holy Cow!

French Toast Alerts

For several years I’ve been posting my “French Toast Alerts” on my Facebook timeline. But where did the idea come from?

Well, for starters, working at a grocery store in high school I noticed that any time snow was predicted, certain items seemed to become very fast sellers. Namely, bread, milk, and eggs. What the heck is going on? Are people planning to make French Toast if they get stuck at home??

Fast forward a couple decades and I ran across a Twitter account that was posting “French Toast Alerts”, so I asked if I could steal the idea, he referred me to the original source of these, Universal Hub in Boston. so I reached out to them to see if they minded. They said by all means, have fun with the idea. And so I have had fun with it.

And now when winter weather threatens Eastern Iowa I will often post this nonsense on my Facebook. Sometime I forget, or don’t even realize snow is coming, and stupidly enough someone will reach out to me to see if a French Toast Alert is warranted. So I guess I’ll keep posting them.

Pork Belly Burnt Ends

Our local Fareway grocery store had ordered some pork belly for a customer, and had some left over, so I decided to try smoking some. My original plan was to make bacon, but I got up one day and the weather was perfect to sit outside smoking meat, and I hadn’t cured my pork belly (which takes 7-10 days) so I decided on Pork Belly Burnt Ends.

I started with 1/2 of a pork belly (about 7lbs) with the skin removed. There’s a lot of fat on pork belly, and you want to leave a fair amount, but trim away some excess. I probably had over a pound of fat that I removed.

Trim excess fat
cut the meat into 1 1/2 to 2 inch cubes.
apply Extra Virgin Olive Oil (enough to coat the meat) and your favorite dry rub (if you don’t have a favorite I recommend making up some Raichlen’s Rub #2) – Be generous (use about 1 cup of dry rub for 5 lbs of meat).
Smoke for three hours at 225-250 degrees or until you like the color of the meat. A nice bark will form starting around the three hour mark.
Next, add the cubes to a pan (we like a heat-proof disposable pan). Into the pan add the braising liquid. We use BBQ sauce to really add that extra flavor (about 1 cup), 3-4 tablespoons of butter, which adds richness and acts as a fatty binding agent for bringing the sauce and honey together, and then 2 tablespoons of honey (or agave) to bring a stickiness and sweet characteristic. Then mix them all together
Then cover and braise in smoker for another 60 – 90 minutes. You will find that the liquid braises at or near a boil and that the fat renders down in the burnt ends keeping the pan moist. Again, you have added additional fat in the butter, the honey as a binder and the sauce for flavor to really render out the fat that is in the pork belly.
Finally, remove the foil pan cover and cook for another 15 minutes to let the heat tack up that sauce,

Sauce:

1 cup BBQ sauce
3 tablespoons unsalted butter
2 tablespoon honey

Notes:

I smoked these for 3.5 hours at 325° using Apple wood in my Masterbuilt electric smoker. I then followed that up on the Weber Kettle charcoal grill using Kingsford charcoal with some apple wood chips thrown on top over indirect heat for 30-40 minutes to get a better bark on them. I then sauced them up and braised them on the Weber gas grill (mainly because I could control the temperature better than on the charcoal grill) for 45 minutes at 250° before removing the cover to tack them up.

This recipe is based on one I found here: http://www.vindulge.com/2017/05/smoked-pork-belly-burnt-ends-recipe-and-video/

On the workbench – Vintage RCA portable TV

Years ago I picked up this old RCA portable television, model 8-PT-7030 manufactured in 1956. Someone on the rec.antiques.radio+phono Usenet group was giving it away for the cost of shipping, which was around $30. At the time it had a broken high voltage rectifier tube. Other than that, I was unsure of it operating condition. It sat around for close to 10 years.

The first thing I needed was a schematic, and at the time I was unable to locate one online. It occurred to me that my friend Mel W0MDM might have one at his TV repair shop in Estherville. The next time I was passing though I stopped to sell hello and see if he had schematics, and sure enough, he did.

The first problem I ran into in the repair process was a lot of melted wax on the back of the rectifier tube socket, which had migrated into the socket itself. I’m not sure if this wax melts out of the high voltage transformer, or if it’s there to prevent arcing. Either way, it had made a bit of a mess. I tried picking the wax out with some dental picks, but wasn’t entirely successful. I got busy with work so the set got put on the shelf in the backroom for the next 10 years or so.

Last month I dug it out and decided to see if I could make it work. I used my hot air soldering station to blow the wax out of the tube socket and replaced the bad tube. The set still didn’t turn on.

I was able to find a full service manual for the set, a copy of which I have uploaded here. This was very helpful, as it allowed me to discover that the chassis comes apart into two halves for easier service.

I don’t have a tube tester, so I’m not able to check any of the tubes. I also didn’t have a cord that would allow me to power it up on the bench with the cabinet removed. I could have rigged up a “suicide cord” to power it, but I decided against it. At a minimum the set needs the selenium rectifiers and the electrolytic filter caps replaced. And then there’s an almost 100% chance that some or all of the 31 wax/paper capacitors are bad. Five of those are not available in the correct values and voltages. The available parts would cost around $55, but still no guarantee that all 16 tubes are good. Or that the CRT is good.

While this would be a fun project, I decided to just clean it up as a display piece for now. Even if it worked, there’s no analog signals left to display so I would have to feed this with an RF modulator to get a picture. It would look pretty neat in my basement bar, but even not working it will make a nice display piece.

Hamfest Find – Vintage Bearcat III Scanner

When I was kid my grandma always had a police scanner going. My brother and I thought it was pretty neat to hear the police, firemen, and ambulance talking. I can’t remember exactly which radio she had, but I do remember that it was a Bearcat, and that it had the red LEDs and there were lockout switches for each channel.

Later on when I was in high school I bought my own police scanner, a Bearcat BC70xlt. Two of the channels I had programmed were local 2m ham radio repeaters. Not having a ham radio license, my brother and I both put CB radios in our cars, as did many of my friends. We had a lot of fun with those CBs, but they sure left a lot to be desired.

We noticed that one of the kids at our high school had a lot of antennas on his car, so one day I asked about them. It turns out that he was a ham, and he told me I needed to throw away that CB and get a ham radio license, which I eventually did. That kid turned out to be a lifelong friend, we still chat on Facebook several times a week.

Fast forward 25 or so years later and I ran across this old Electra Bearcat III police scanner at the Cedar Rapids hamfest. It immediately reminded me of my grandma, and how her police scanner changed my life by sparking an interest in radio communications. The guy was asking $10 for it, with the original box, manual, power cord, and mobile mounting bracket. How could I pass that up?

The radio was in mint condition inside and out. No dust bunnies and very clean. The only real cleaning it needed were the knobs, which I scrubbed with a toothbrush and some Simple Green. A quick wipe down of the rest of the radio and looked great.

Of course, this being a crystal set, I knew it wasn’t going to hear any of the channels our local public safety agencies were using. Even worse, once I got it home I realized that the BC3 used optional IF boards to listen to two different bands. This radio only had one installed, and it was UHF, and I needed VHF. But I found another BC3 on eBay for a bit over $15 shipped, so I went ahead and ordered it so I could rob the IF board from it. It even had a couple of crystals that would work for me locally.

Next I needed crystals. Certainly ICM or Jan would have them. Nope. Both are out of business. Looks like it was back to eBay. Several sellers had scanner crystals, and I finally found a seller that had what I needed. I ordered five crystals for $50 shipped, a lot more than I really wanted to pay, but what good was this thing without the crystals? Once they arrived I installed them and sure enough, I heard the fire department being paged out and the police dispatcher as well.

I put the scanner on the bench and tested with an IFR-1100 service monitor and the receiver is actually quite hot, at about 0.2uV of sensitivity. Not bad for a scanner that’s nearly 40 years old! I considered re-capping it, but since it was working just fine I decided not to bother.

This unit is now living in my basement bar, right next to some 70s vintage pinball machines. It looks right at home there, and every time I see it I can picture grandmas scanner on top of her refrigerator, and I’m reminded of childhood visits to grandma and grandpas house.

Ham Radio Insurance

When I was getting quotes for homeowners insurance I specifically asked my agent about coverage for my tower. It turned out that for just a few dollars a year I could purchase a rider to cover my tower, however the standard $1,000 deductible applies, and it’s not clear if the antennas and rotor are covered. I decided that I was okay with that for the time being.

But I recently upgraded three smartphones, two being Apple iPhone 6s devices, and a Samsung Galaxy S7. The cellular provider is happy to provide coverage for accidental damage for only $9/mo per device, with a $50 deductible, and I have to send the phone off to some 3rd party to attempt to repair it, and if they can’t, they replace it with a “comparable” refurbished device. That doesn’t sound like a good deal at all.

Instead, I purchased a policy from Ham Radio Insurance Associates to cover not only my ham radio equipment, but my smart phones as well. The coverage was less than $100 a year. Next year I’ll probably add my tower, antenna, and rotor to the policy as well, instead of purchasing the rider to my homeowners policy.

If you are wanting to insure your ham radio equipment, be sure to check out HRIA. They have great rates, and the agent is a ham operator.

No, I will not fix your computer

If you suspect you are infected with Crypto malware (Cryptowall, Cryptolocker, TeslaCrypt, etc) DO NOT follow this guide!

This guide is heavily based on a Reddit post by: /u/cuddlychops06. I have reviewed it and given it two thumbs up!

Purpose & Scope of this Guide:

This guide is designed to assist you in removing malware from an infected system that successfully boots. If you perform the following steps exactly as described, this will solve your problem in over 90% of scenarios. That said, not all malware is created equal, and there will be times that this guide fails in removing malware. It is recommended to only accept advice from a “Trusted” technician. (W0HC is a CompTIA A+ Certified Technician). This guide is written in layman’s terms so that most people will be able to understand it with ease.

Disclaimer:

The following instructions are recommendations only. You take full responsibility for any steps you choose to perform on your computer. While the following recommendations are performed without issue on countless machines, there is always a risk of damaging your Operating System or experiencing data loss on any machine. It is solely YOUR responsibility to save all work and back up any and all important data on your system before proceeding. Also note that once a computer has been compromised with malware, it should not be considered clean until a complete reformat has taken place.

Malware Remediation Steps:

Before proceeding, go into your browser’s extensions and remove all suspicious items. Also go into your browser’s settings and remove any default search providers and unusual homepages. If you are unsure how to do this, proceed to Step 1.

Download and run the following tools in this order. Run all tools unless otherwise instructed. All tools should be run in Normal Mode (not Safe Mode) unless you are unable to boot Normal Mode, or the scans fail in Normal Mode. All tools must be run under an Administrator account. Do not remove any tool-generated logs in the event a helper needs you to post them to further assist you.

1) Run rkill.com. Sometimes it takes a few minutes to finish. Do not reboot when done.

Consider enabling two-factor authentication on supported apps & sites.
Revoke app-specific passwords to things like gchat, Facebook, etc
Consider resetting your Windows user account password
Install a better anti-virus.

Yaesu G-800SA Rotor not turning when cold

Yaesu G-800SA Rotor Controller I’ve had a Yaesu G-800SA Rotor on my tower since I built it in 2009. I mostly like it, especially the nice big dial on the controller. The fact that it only needs 4 wires to operate is also a plus.

One thing I don’t like about this Yaesu Rotor is that it’s very cold blooded. I tend to take a bit of time off work over the holidays, so I like to mess around on the ham bands. Unfortunately, here in Iowa it’s often quite cold outside at this time of year. Today, for example, overnight we had a low of -4°F, and as of lunchtime it’s only reached 10°F.

It seems that when the temperature is cold, below about 10°F, the rotor stops turning. I haven’t yet been able to determine if this is a rotor issue, or some other problem related to my installation. I’m not very inclined to climb the tower when it’s cold out to see where the issue lies!

I’ve been pondering if there’s a way I could warm the rotor up a little bit, assuming I determine the issue is in the rotor. Or maybe it needs a different type of grease more suited to the cold Iowa winters.

In any case, while typing this post the rotor warmed sufficiently that I now turns. Time to check out the bands!

Next Time Someone Claims To Be An ‘Engineer,’ Give Them This Test

(I found this on Facebook and have re-published it here. I do not know who the original author is.)

Engineering is so trendy these days that everybody wants to be one. The word “engineer” is greatly overused. If there’s somebody in your life who you think is trying to pass as an engineer, give him this test to discern the truth.

ENGINEER IDENTIFICATION TEST

You walk into a room and notice that a picture is hanging crooked. You…

Straighten it.
Ignore it.
Buy a CAD system and spend the next six months designing a solar-powered, self-adjusting picture frame while often stating aloud your belief that the inventor of the nail was a total moron.

The correct answer is “C” but partial credit can be given to anybody who writes “It depends” in the margin of the test or simply blames the whole stupid thing on “Marketing.”

SOCIAL SKILLS

Engineers have different objectives when it comes to social interaction.

“Normal” people expect to accomplish several unrealistic things from social interaction:

Stimulating and thought-provoking conversation
Important social contacts
A feeling of connectedness with other humans

In contrast to “normal” people, engineers have rational objectives for social interactions:

Get it over with as soon as possible.
Avoid getting invited to something unpleasant.
Demonstrate mental superiority and mastery of all subjects.

FASHION AND APPEARANCE

Clothes are the lowest priority for an engineer, assuming the basic thresholds for temperature and decency have been satisfied. If no appendages are freezing or sticking together, and if no genitalia or mammary glands are swinging around in plain view, then the objective of clothing has been met. Anything else is a waste.

DATING AND SOCIAL LIFE

Dating is never easy for engineers. A normal person will employ various indirect and duplicitous methods to create a false impression of attractiveness. Engineers are incapable of placing appearance above function.

Fortunately, engineers have an ace in the hole. They are widely recognized as superior marriage material: intelligent, dependable, employed, honest, and handy around the house. While it’s true that many normal people would prefer not to date an engineer, most normal people harbor an intense desire to mate with them, thus producing engineer-like children who will have high-paying jobs long before losing their virginity.

Male engineers reach their peak of sexual attractiveness later than normal men, becoming irresistible erotic dynamos in their mid-thirties to late forties. Just look at these examples of sexually irresistible men in technical professions:

Bill Gates.
MacGyver.
Etcetera.

Female engineers become irresistible at the age of consent and remain that way until about thirty minutes after their clinical death. Longer if it’s a warm day.

HONESTY

Engineers are always honest in matters of technology and human relationships. That’s why it’s a good idea to keep engineers away from customers, romantic interests, and other people who can’t handle the truth.

Engineers sometimes bend the truth to avoid work. They say things that sound like lies but technically are not because nobody could be expected to believe them. The complete list of engineer lies is listed below.

“I won’t change anything without asking you first.”
“I’ll return your hard-to-find cable tomorrow.”
“I have to have new equipment to do my job.”
“I’m not jealous of your new computer.”

FRUGALITY

Engineers are notoriously frugal. This is not because of cheapness or mean spirit; it is simply because every spending situation is simply a problem in optimization, that is, “How can I escape this situation while retaining the greatest amount of cash?”

RISK

Engineers hate risk. They try to eliminate it whenever they can. This is understandable, given that when an engineer makes one little mistake the media will treat it like it’s a big deal or something.

EXAMPLES OF BAD PRESS FOR ENGINEERS

Hindenberg.
Space Shuttle Challenger.
Hubble space telescope.
Apollo 13.
Titanic.
Ford Pinto.
Corvair.

The risk/reward calculation for engineers looks something like this:

RISK: Public humiliation and the death of thousands of innocent people.

REWARD: A certificate of appreciation in a handsome plastic frame.

Being practical people, engineers evaluate this balance of risks and rewards and decide that risk is not a good thing. The best way to avoid risk is by advising that any activity is technically impossible for reasons that are far too complicated to explain.

If that approach is not sufficient to halt project, then the engineer will fall back to a second line of defense: “It’s technically possible but it will cost too much.”

EGO

Ego-wise, two things are important to engineers:

How smart they are.
How many cool devices they own.

The fastest way to get an engineer to solve a problem is to declare that the problem is unsolvable. No engineer can walk away from an unsolvable problem until it’s solved. No illness or distraction is sufficient to get the engineer off the case. These types of challenges quickly become personal – a battle between the engineer and the laws of nature.

Engineers will go without food and hygiene for days to solve a problem (other times just because they forgot). And when they succeed in solving the problem they will experience an ego rush that is better than sex – and I’m including the kind of sex where other people are involved.

Smoking Meat

Over the past several years I’ve taken up a new hobby, totally unrelated to amateur radio, but closely related to ham. Smoking meat!

This topic is a bit RF related. Back in 2008 we had a new transmitter installed at work, and we had problems with it from day 1, so the manufacturer sent us a contract engineer to look into the problem. This guy went on and on about smoking ribs. I love ribs, and never really mastered grilling them on a charcoal grill. Anyway, he convinced me that I needed an actual smoker.

I started off with a cheap $50 electric smoker that was on clearance at Home Depot, and it worked well enough that I used it until a few months ago when Amazon had a special on a Masterbuilt Electric Smoker. I pulled out my credit card and two days later that bad boy was on my front step.

I mostly smoke Baby Back Ribs, which I generally buy at Sams Club, which is a couple dollars a pound cheaper, unless the local butcher has them on special. I use the 2-2-1 method. Two hours in the smoke, two hours wrapped in foil with a bit of apple juice and back on the heat, and then one hour unwrapped to firm them up a bit. I try to keep the temperature around 225F. Low and slow.

Always remove that shiny, tough membrane from the back of the ribs. Then rub them with your favorite BBQ rub. The recipe I use is a tightly held secret. They come out so good you don’t need BBQ sauce.

I’ve also smoked turkeys, and tried a few briskets. The briskets take a lot of patience, as you need to smoke them very slowly at low temperatures. I haven’t really mastered them yet.

My wood of choice when I’m smoking has been Apple. I’ve been told that Hickory and Mesquite and be a little too strong, but I will be experimenting with them and Pecan this summer. I’m also going to branch out and smoke some other meats, especially chicken. I have ten pounds of chicken hindquarters in my deep freeze that I bought on special over the winter, and I’m really looking forward to smoking them if this Iowa weather ever warms up enough that can sit outside and enjoy the process of smoking them. A nice warm day, lots of smoke, a book, and beer in the hand is what I’m looking forward to! And then plenty of friends to enjoy the results with!

Today I ran across a handy chart Wood Smoking Flavor Chart, so if you’re interested in smoking meat that will help you choose which wood to use.

Have fun, and enjoy a tasty meal!
