On No. 1: the 1916 Marconi Yearbook says QRK means "How are you receiving" / "I am receiving well." QSR means "Will you dispatch the radiotelegram?" / "I...

Going from memory ... Always a risky proposition. Many if not most "entertainment" radios used a 3.2 ohm voice coil _Impedance_, (usually measured at 1000...

Ok, well maybe then the mystery (to me) has been solved. I looked up a bunch more of these old QSL cards and the ones listed below all say something to the...
The four-letter codes were ARRL specials, a sort of dialect for "amateur radio" use. As laid out in the '26 Handbook, QRAR: "Is your callbook address...

... He was talking about resistance, he was using a digital VOM to try and read the coil resistance. He didn't have a set of clip leads so he was having...
Yeah, that's about right for a 3.2 ohm impedance voice coil. I had a friend who went through a whole case of speakers looking for one that read the 3.2 ohm...
If you really wish to know, buy an HP200 series Audio Oscillator at the next Ham Fest. I then connect a 6.8 ohm (carbon) resistor (which you would measure...

I'm kinda surprised he was looking for DC resistance though. Our replacement cones were marked with impedance rather than DC resistance. Again, really not all...
I don't have an answer, BUT, I think you need to define the number of stages. If it is defined as one, then it would be the first Fleming valve (diode)...

... If the impedance is around 4-6 ohms and the power handling capacity is around 3-10 watts the speaker should work well on that radio. I have a 37-620 with...
TRF radios first came to market between 1921 1922. They had two or three dials. One to tune the antenna stage then the detector stage. # dial radios tunned the...
