Retro QRP Rigs of the 1960's, 70's, and 80's -- Video by Mike WU2D

It is time to put aside (again!) all of the heated ideological arguments about the power level that defines "low power."  Just sit back and enjoy this wonderful trip down QRP memory lane. 

Mike's description of the simple, single-transistor QRP transmitter was really nice.   I recently made something similar: https://soldersmoke.blogspot.com/2023/02/first-qso-with-high-school-receiver-100.html  And Mike does a nice plug for our beloved Michigan Mighty Mite.  Go CBLA! 

The modular idea:  words to live by my friends. 

40673!  TT2!  And G3RJV's PW Severn - indeed, bow your heads!

Wow, the Ten Tec Power Mite (or Might!) -- I still want one.  Same for the Argonaut -- what a great name (sounds like a "magic carpet), and with SSB to boot!  I want to join the Argonaut cult! 

I have both the HW-7 and HW-8 (the HW-8 is heading to the Dominican Republic).  This video makes me want to fire up the HW-7.  Maybe on 40.  

My 40 meter homebrew rig (Digi-Tia) has in it the filter from that old Yaesu FT-7 rig.  The filter was given to me by Steve "Snort Rosin" Smith.  https://soldersmoke.blogspot.com/2015/05/bitx-digi-tia-build-update-2-installing.html  

Thanks to Mike for including me in the credit roll at the end.  What a great group of people -- it is a real honor to be listed with those folks. 

Tim Hunkin on Drilling Holes (Secret Life of Components Video)

 I guess that aside from being a great video, this is something of a test of technical nerdy-ism.  If you find this hour long video really interesting, well, you know... 

Really cool stuff from Tim Hunkin: 

-- I liked the angle driller.  Need one. 

-- The placement of the magnets near the hole to catch the shavings was really cool. 

-- Tim's reluctant admission that it is just better to buy new drill bits (as opposed to sharpening old ones) is good advice. 

-- WD-40!  Yea! 

-- Note:  No white "Boffin" coat for Tim.  Just "overalls."  But as I watched I found myself thinking that he could probably have used an armor plate or at least a Kevlar vest amidst all that flying metal. Perhaps a bit more eye protection too...  

-- Fiddley.  A useful tech term.  

--Swarf:  Another useful tech term:  the metallic remnants (shavings) of drilling. 

-- The digi readout on the milling machine looked really useful. 

Finally, I loved the sign that Tim has posted in his workshop:  

SMALL HADRON COLLIDER

Four Old BBC Shows on Radio: Hams, Physics, and Antique Wireless

The first one, about ham operators in general, is pretty depressing. Then it goes downhill as they shift to those who are listening to baby monitors and cell phones.  Yuck. 

The second one seems to show some physicist having understandable difficulty explaining particle-wave duality in a short TV segment.  

There is a short bit (that I didn't quite get) about the BBC's "Teddy Bear's Picnic."  

The final one is about Gerald Wells and his Antique Wireless Museum in South London.  Note the white coat -- clearly a boffin.  For a while I confused him with Rupert Goodwins G6HVY (similar white coat, but a different bloke).  

Helge LA6NCA's Altoids Tin Receiver

Here's another great video from Helge LA6NCA.  This is a follow-up to his Altoids Spy Transmitter project.   Really well done.   Hack-A-Day called this receiver "regenerative" so naturally I was disappointed, but when I watched I realized that it is NOT a regen but is instead a direct conversion receiver.  TRGHS.  All is right with the world.  Thanks Helge!  73 

Artie Moore and the Titanic

I had never heard of Artie Moore, but his is a very interesting story from the earliest days of radio.
