The basic laws of physics, energy transfer, and math have not changed. No matter what the technology is “in between”, it is acoustics that drive the microphone and electromagnetics that drive the antenna. A joule is still a watt-second and power is still dissipated as heat if not transferred to the load. Here is a controversial thought - - maybe folks were just smarter back then because the had to be - - things were not handed to them on “silver platter” as they are today. I have spent 45 + years mentoring colleagues on the nuances of RF test and measurement and it starts with the basics.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>Art<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>NF1A<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> bars <bars-bounces@w1hh.org> <b>On Behalf Of </b>Edward Lipchus via bars<br><b>Sent:</b> Sunday, December 29, 2024 10:34 PM<br><b>To:</b> Juan Jiménez <k1cpr@bd5.com>; geoffreyf@comcast.net; W1hh <bars@w1hh.org><br><b>Subject:</b> Re: [bars] Radio Book<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><div><p class=MsoNormal><span style='font-family:"Times New Roman",serif'>I hesitated to add my two cents, because I felt a dismissive tone to your comment.

A tuned circuit is still a tuned circuit. A center-fed dipole is still... ditto.
