Are you around Palm Beach and want to take the exam to become an amateur radio operator or upgrade to a higher license class? See below.
Still need to study or take a practice exam to see if you’re ready? Check out HamStudy.org.
Bring photo ID and a calculator to the exam session. Since this is a Laurel VEC session, don’t bring the exam fee, as there is none. 😉
This Sunday the Palms West Amateur Radio Club Laurel VEC team will be giving exams for all classes of Amateur Radio licenses.
Come and test with us on Sunday, January 8 at 10:00 AM at Fire Station #28, 1040 Royal Palm Beach Blvd, Royal Palm Beach 1 block south of Okeechobee Blvd. There is no charge, and you do not have to register.
If you are coming to upgrade, please bring a copy of your license and a photo ID card, like your driver’s license. There is no charge for testing!
If you know of someone who has been studying to become a ham, bring them along, even if they feel they need to do more studying.
And if you are a VE, please let me know if you can come and help.
I’m so very very DONE and so are your chances of ever getting anywhere on the roads in northwest Miami-Dade in 2020. I had heard nothing but radio silence on this project for over a year, and this is probably why– they were trying hard to apply decorative wallpaper to an elephant in the room to conceal it.
“It is unlikely that all needed interchange improvements will be approved and constructed by 2020, the build out year for ADM,” Lisa Colmenares, a state transportation planner for South Florida, wrote in a Nov. 23 letter to Miami-Dade. “If any of the interchange improvements fail to be approved … by 2020, the base transportation network that is the foundation of [the county’s] traffic analysis will be invalid.”
This monster is nearly eight and a half inches wide.
Spade tipped needle.
The passive scale illumination: a ground glass band on top allows ambient light to light the dial.
Connection post. This isn’t exactly a blazing sensitive meter– putting a digital multimeter set to ohms across it yields no visible deflection. (Some meters peg!) Setting the DMM to diode check, which usually applies 5mA or so, gave me about a 61. Please admire that rough carpentry. I love finding things like this!
Better view of that nicely made wooden base. Unlike the edges of the connection post holes, the outside is immaculate.

What was this made for? Judging by the lack of any visible brand name, wood tabletop base, and unusual scale with no units, I’m suspecting it was a classroom/lab piece. You’d calibrate with a known voltage reference and do the math yourself. You know, old school nonsense. 😉
The low sensitivity is curious too. I’ll have to test later and see just what scales out to a 100.
I did open the meter briefly because there was some loose material rattling around that I didn’t want damaging the movement. An old wire wound spool resistor is mounted inside in parallel with the movement, likely for damping. It looked similar to the spools in my Weston but covered in cloth tape instead of wax.
Winter is to COLD as Florida is to: A) DERP B) HERP DERP C) DURRRRRRRRR D) All of the above

I’m still baffled by this one. I’m going down 595 eastbound past Davie when there’s suddenly a massive bang… I didn’t see any objects in the road prior to this but something must have hit hard. I pulled over and found the wheel well liner wrapped around the wheel and what’s left of the front bumper unsnapped from its tracks.
There was once a big black plastic pan here.
Flapping in the breeze.
I do hope that dangling wire would have been for the fog lights on a fancier trim model
The remains of the pan I had to remove because it was dragging and there’s nothing left to attach it to
There is no real evidence of what may I may have hit in the road, but it sure did a nice job of demolishing all the plastic parts.
Oh well. Likely coming soon: a post in which I detail reassembling the front of a car in 88 degree December weather.
This is one of the most common power strips available now, as it’s the least expensive available out of China. Note what happens if you miss just a little plugging in a two prong plug. If you touched the prong here and any grounded object, hi diddly shockarino, neighbor!
But guess who doesn’t seem to have a problem with this.
This strip is available under a number of brand names including General Electric, Westinghouse, Belkin, Sunbeam, whoever the retailer licensed a brand name from that week. You should not buy it.
Best driver of the year award goes to….. Girl who spent more on her weave and her phone than she did on her car, who slowly drifted out of her lane while poring over something on her phone.
I didn’t notice this until I felt a very wrong sensation and heard an odd sound and my car started wanting to push left. I looked over and the first thing I saw was my rear view mirror stuck right through her open window next to her face.
I realized I didn’t want to spook her because she’d do something and make it worse… So I gently moved left, getting my mirror out of her oblivious face and gave her some room…. then let loose with the horn.
The phone popped back down and she swerved all the hell over the place before slamming the gas and leaving a cloud of blue gray smoke. Then the phone popped right back up again and she rear ended a dump truck ten seconds later. Of course since she’s already on SR-22 she just ran. So did the dump truck.
I was testing something with my trusty old Tektronix 2232 100 MHz digital storage scope and this happened:
My guess as to what I’m seeing: a pretty significant bit of the input to the DAC (digital to analog converter) that sets the beam’s horizontal position is stuck, causing the display to break up and overwrite itself in unreadable stripes.
This display is of the vector type. There is no linear, raster scanning like in television or computer monitors; it’s more like an electron beam Etch-A-Sketch. Two DACs driven by the microprocessor set the beam’s horizontal and vertical deflection and it excites the phosphor wherever it lands. A control grid in the cathode ray tube allows it to be blanked to be moved without lighting the phosphor it crosses.
When this skipped around the beam wasn’t blanking; you could see it smear right back.
I tried power cycling. It’d be okay a minute or so after a minute off then do that again.
I tried clearing all settings and memory.
I tried looking through the service manual.
I smacked it.
The problem immediately cleared and does not come back.
Why didn’t I try this first? Am I losing my mind here?!
The fault was likely a loose connection at a backplane connector, socketed IC, or ribbon cable down inside, or maybe even a cracked solder joint.
If it recurs I’ll investigate, but for now I’ll rest easy knowing I don’t have to replace this wonderful scope I’ve used for years with some soulless modern piece of Chinese plastic poo that can’t actually do X/Y plot mode right.
