How to Organize a Small Shack

A YouTube comment from Paul VK3HN sent me back to "The Spirited Man" YouTube channel, and one of the first things I found was this video about how to organize a small space.  This is very relevant to my shacks in Virginia and in the Dominican Republic. 

Lots of good ideas here, but that propane heater kind of scared me.  And it seemed inconsistent with concerns behind the fire-preventing garbage can.  What do you folks think? 

Thanks Paul.

Bill's report from SolderSmoke Shack South: The tropics:  What this means.  Guapo wouldn't  go out when the sun was overhead. 

 Skies not great for astronomy now.  But we see a lot of satellites, and meteors.

Antenna developments:   1/4 vertical on a fishing pole.  

Lightning suppression coming for the building. Lightning suppressors.  Got 2.  Good video from the IMSAI guy: https://www.youtube.com/watch?v=7EyABPuNDMA Argon gas suppresion tubes.Need to crimp! 

Hurricane prevention. Metal storm curtains. 

Thinking of solar panels. 12 panels, 5 kW system.  Probably without batteries.  What do you think? 

A golf cart. 

New PC.  BeeLink.  Very tiny! (palm of your hand)   24 inch screen. Works well https://www.amazon.com/dp/B0BVFKN7ZL?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

A very satisfying fix on the 15/10 rig -- loose connection to RF amp.  The highly suspect Ramsey Kit Amp was NOT the culprit!  Got to use the new Rigol DS-1102.  A fun fix. Will build a second CCI amp.

Two Great (but Old) Videos about Waves

I've had both of these videos on the SolderSmoke blog already, but an e-mail from Farhan reminded me how good they both are. If you are averse to older material you might not want to watch -- but you would be missing out on some wisdom.  

 

Monitoring Maritime Radio Messages with YADD

 

Click on the image for a clearer view

This is really cool and very easy.  Easy nerd thrills.  

On Friday, Steve VE7SL, put up a blog post on how we can relive the glories of our youth by monitoring HF long-distance maritime traffic.  In the old days the ships were on CW and many report that it was great fun to listen to the various "fists" in action from coastal stations, and from ships on the high seas.  While the CW is long gone, this maritime traffic is still on the air.  Today they are using a SEL call system called Digital Selective Calling or DSC.  

Happily, it is very easy to decode these transmissions.  Steve recommends a program called YADD (Yet Another DSC Decoder).  I downloaded it in seconds and had it installed on my computer in minutes.  Next I had to find a general coverage receiver.  I thought about pressing my old HQ-100 into service, or maybe even the S-38E, but a cooler head prevailed.  I remembered that Farhan had given us a general coverage receiver in his uBITX transceiver.  So it came off the shelf and got powered up.  Around dawn on October 14, 2024 I put the receiver on 8.415 MHz LSB.  I didn't even have to do a real connection to the computer -- I just put the speaker close to the mic and that was sufficient.  

Boom.  Soon I was getting signals from ships afloat and from coastal stations.  I heard Shanghai, New Zealand, and Australia.   See above.   From the U.S., I heard Miami, but the most emotional for me was hearing the station at Pt. Reyes, in California.  This is the station that Dick Dilman W6AWO has volunteered at for many years.  FB.  

Back in 2017, Steve had another post on DSC and YADD: 

https://ve7sl.blogspot.com/2017/08/yadd.html

Thanks Steve! 

This site explains very well what DSC is.  From this I think we can see that there is nothing illegal about using YADD to monitor the DSC alerts (that are all emergency-related):  https://infoshipping.tripod.com/gmdss_dsc.html

The Transistor that Changed the World -- the MOSFET

Another great video from Asianometry.  

My only quibble is that it kind of left unclear the differences between JFETs and MOSFETs.  After all, we still use both.  Note our beloved J310 JFET.  And the IRF510 is a MOSFET.  

Google's AI explains: 

A JFET (Junction Field-Effect Transistor) and a MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) are both types of field-effect transistors, but the key difference is that in a JFET, the channel conductivity is controlled by a reverse-biased PN junction, while in a MOSFET, it's controlled by an electric field across an insulating layer between the gate and the channel, allowing for a much higher input impedance and greater design flexibility in MOSFETs; essentially, MOSFETs are considered a more advanced version of JFETs with superior performance in many applications like high-speed switching and integration into complex circuits. 

Tally Ho! Leo Solders -- Aurora -- Satellites -- Meteors -- Tides -- Starlink

I've been following this YouTube channel, probably since early in the pandemic.  It is not about radio, but in this episode we see Leo actually do some soldering.  NOT BAD!   Lots of other related stuff.

What Happened to the SolderSmoke Blog?

 

The conclusions of this article ring true, but I am not certain that changes to the Google algorithm, or the introduction of AI answers to Google queries explain the changes that are reflected in the above chart. 

Here's the article: 

https://www.bbc.com/future/article/20240524-how-googles-new-algorithm-will-shape-your-internet

Take a look at the traffic going to the SolderSmoke blog over the last year (see chart above). 

Something bad happened to us around April 15.  

What do you guys think?  What happened?

4Z4GE's Homebrew Tube SSB Transmitter from Israel, 1974

https://www.nzeldes.com/Miscellany/SSB-rig.htm 

Very cool. I like his description of how he found parts for this transmitter:  

The power amplifier tubes needed ventilation as well as shielding; that was always a challenge because I had no good source of perforated metal. The black sheet with the round holes actually came from the cover of a car air filter that I found in the trash.

There is a lot more interesting stuff on Nathan Zelde 4Z4GE's site: 

https://www.nzeldes.com/possiblyinteresting.htm

Thanks Nathan! 

Homebrew Receiver -- AG5VG's 20 Meter "Mythbuster" Receiver

Michael has the receiver done and is wisely heeding Farhan's advice about pausing to enjoy the homebrew sounds.  

I was pleased to see someone else using the FT-101 VFO.  Great piece of gear.  

On to the transmitter!  

Fernando's Rigs -- Vintage Ham Radio Receivers

Thanks to Rogier PA1ZZ for sending me this YouTube link.  It is a truly wonderful channel from Spain. Not only the Collins Gold Dust Twins, but also lots of great (and not-so-great!) older receivers.  SP-600s, S-38s,  Rhode and Schwartz rigs, lots of great stuff.  Go to the "Videos" link and enjoy the Thermatron goodness.   Thanks Rogier!  And thanks Fernando!
