Electronic Toys and Their Influence on Us

4 July 2024 at 10:44

Mike WU2D recently put out this interesting video.Β  I vaguely remember the springs on the Radio Shack kits -- I also remember (bitterly) not being able to get their shortwave receiver to work.Β  Β I really wanted to tune in HCJB and Radio Moscow.Β  This probably led me to ask Santa for a Lafayette HA-600A receiver in 1973 or so.Β 

An earlier influence was the little intercom kits.Β  I think they worked over the AC lines?Β  Β We took some of them to the beach bungalows we had in Lavallette NJ.Β  With them we were able to speak clearly to similar units in nearby bunalows.Β  Wow, that was cool. That got me interested in radio.Β 

Cassette tape recorders were another early influence. I still have a recording I made with a tape recorder I got for Christmas, probably in 1972.Β  I used this recorder to practice CW for the ham exam.Β 

I managed to escape the CB madness.Β  Β But I came close to falling into the groovy psycho stuff of the early 1970s.Β  I remember the Transcendental Meditation gizmos.Β  I never built one, but if I had I may have been better off with CB.Β 

I kind of wish I had followed the example of the Woz and Jobs by making telephone blue boxes.Β  This could have led me to riches.Β  But as Jean Shepherd used to say, young men often come to a fork in the road: one path leads to wealth, the other to ham radio flea markets.Β  I got on the second path.Β Β 

Thanks Mike!Β

Woebot -- An AI-Based Therapy Bot for Us?

8 April 2024 at 15:48

Β 
This was on 60 Minutes last night.Β  Of course it made me think of our many "Tales of Woe."Β  Perhaps this could be of use to us.Β  Β But I wonder how the bot would react to our typical problems:Β 

"I am feeling bad about myself becasue my RF amplifier keeps going into oscillation.Β  What should I do?"

"My opposite sideband suppression is inadequate because my filter skirts are too wide. What is your advice?"Β 

"My LC VFO drifts slightly and my SDR-using friends taunt me about this.Β  I feel dejected.Β  What should I do?"Β Β 

"The Raspberry Pi in my SDR rig is hallucinating and I can't find the needed wisdom files. Is there a support group for this?"Β 

"I have discovered spurs in the output of my transmitter.Β  They are 60 db down, but I still can't stop thinking about them.Β  What should I do?"

I can't help thinking that if Jean Shepherd had access to something like this, his Heising modulator trouble might not have spoiled his date with the girl from his school.Β Β 

What do you guys think about the Woebot?Β Β 

Listen to me talking to Jean Shepherd in 1976. I was 18 years-old.

18 March 2024 at 10:09


Wow, here is a blast from the past.Β  I recently read a good article about Shepherd by A. David Wunsch in the Spring 2022 issue of the AWA Journal. David correctly focused on Shep's obsession with the Heising modulator, and the very negative impact ("Your mother should take you to a doctor!") that this had on his dating life.Β 

I was telling my wife about this article, and I commented that I had once spoken to Shep during an early morning call-in show on WMCA New York.Β  I told her that someone had sent me a recording of this brief conversation.Β 

The call took place in 1976.Β  Shep was appaearing as a guest on the late-night radio show of Long John Nebel and Candy Jones.Β  Β I was 18 years old. My callsign was WB2QHL.Β  The recording was sent to me by Matt KC8COM in 2006. Thanks Matt!Β  In 2008 I played the recording during SolderSmoke Podcast #90.Β  But I think this call merits a post on the SoldedSmoke blog, so here it is.Β  You can jump forward to about 3 minutes, 49 seconds.Β  Β

One side note.Β  I told my wife that some time after the broadcast, I was once again up early in the morning, kind of absent-mindedly getting ready for work when I heard Shepherd talking on WMCA to some guy about ham radio.Β  It took me a moment to realize that this was a re-run, and that that guy was me!Β Β 

When I first listened to this I didn't realize that later in the recording (around 9:30) another fellow calls in an asks Shep about why he uses CW.Β  Shep is kind of short with him and ends up advising him to "go back to CB." I should note that in my conversation with Shep earlier in the program,Β  I told him that I was usually on "40 sideband."Β  He was nice to me, but said that he was mostly on 20 CW.Β 



Here is a good Wikipedia article on Long John Nebel:Β https://en.wikipedia.org/wiki/Long_John_Nebel

And here's one on his wife and WMCA co-host Candy Jones:Β 

Jean Shepherd has Trouble with his Heising Modulator (and his date)

19 February 2024 at 14:38


This is probably Jean Shepherd's best program about homebrew ham radio.Β  It is about how we can become obsessed with the problems that arise with equipment that we have built ourselves, and how normal people cannot understand our obsessions.Β  Β 

I posted about this back in 2008, but I was listening to it again today, and quickly realized that it is worth re-posting.Β  Β Realize that Shepherd's Heising modulation problems happened almost 90 years ago.Β  But the same kind of obsession affect the homebrewers of today.Β Β 

Note too how Shepherd talks about "Heising" in Heising modulation.Β  Heising has an entire circuit named for him, just like Hartley, Colpitts, and Pierce of oscillator fame.Β  Sometimes, when I tell another ham that my rig is homebrew, I get a kind of snide, snarky, loaded question:Β  "Well, did you DESIGN it yourself?"Β  This seems to be a way for appliance operators to deal with the fact that while they never build anything, someone else out there does melt solder.Β  They seem to think that the fact that you did not design the rig yourself makes your accomplishment less impressive, less threatening.Β  This week I responded to this question with Shepherd's observation -- I told the enquiring ham that my rig is in fact homebrewed, but that I had not invented the Colpitts oscillator, nor the common emitter amplifier, not the diode ring mixer, nor the low-pass filter.Β  But yes, the rig is homebrew, as was Shepherd's Heising modulator.Β  Β Β 

Guys, stop what you are doing. Put down that soldering iron, or that cold Miller High Life ("the champagne of bottled beer") and click on the link below. You will be transported back to 1965 (and 1934!), and will hear master story-teller Jean Shepherd (K2ORS) describing his teenage case of The Knack. He discusses his efforts to build a Heising modulated transmitter for 160 meters. He had trouble getting it working, and became obsessed with the problem, obsessed to the point that a girl he was dating concluded that there was "something wrong with him" and that his mother "should take him to a doctor."

This one is REALLY good. It takes him a few minutes to get to the radio stuff, but it is worth the wait. More to follow. EXCELSIOR! FLICK LIVES!
