It was a good day for me and Alex (9 y/o).? He's completed about half (or more) of the kit assembly.? He used a Hakko 936 clone station I had kicking around in the junque and a roll of 60/40 solder

Amazing! Only thing my 19 yr old grandson is interested in is girls and video games.? I have a Le Sauteur de Bayou, receiver eventually used in the Bayou Jumper transceiver that am going to expand

For anyone whom this thread might have discouraged from building this rig,? I thought I better tell the rest of the story....??? I removed T3 and C43 from the circuit and found the power out was

OK.? I have a bunch of regen stuff archived and this was the only one that cam close to fitting your description. But it turns out that schematic doesn't match the actual article from P.E. Oct. '59

No it isn't that one though the 12V6 is wired in similar fashion.? There are only two tubes.? 1/2 of the 12SN7 is a preamp for the 12V6, the other half is a regenerative detector, believe in a

Curt, is it this one from Oct. '59 Popular Electronics? 73.......Steve Smith WB6TNL "Snort Rosin"

It sounds similar to a regen by Newkirk in the September 1992 QST, also reprinted in the book QRP power. It does use two dual section tubes. I built it and it's a good performer. 73- Nick, WA5BDU

Awhile ago, when the regenrx yahoo group was active, I built several different iterations of regenerative receiver on the same small chassis.? It started as a twinplex, then changed to a 6SJ7

Not that I have this all clear in my head. Even if 90 degrees out of phase, the instantaneous power when current is at -45 degrees and voltage at +45 degrees is half of your 54.6 kVA.? But 180

Which is to say that the current and voltage are not both high at the same time. They are out of phase.

Remember that when you multiply the current times the voltage across the capacitor, you are calculating reactive power, not watts. In an example from 66pacific.com, take a 10’ circumference loop

Got to be the "same place and time" thing. No way a system that small can contain anything like a megawatt of power.

I originally wanted to build a surface-mount version of the 2n2/40, but after playing around with a surface mount layout using toroids in the mixers, I wasn't getting the size reduction I was looking

Impressive! That loop is definitely doing the right thing! Jerry

My last map I'll post. This is what I got today at 50mW transmit. If I have all my math right...this is equivalent to about 1 watt CW. 20 Watts SSB. I would really like someone to correct me if I'm

Good question. I see two possible answers, and will expose my ignorance by saying I've no idea which dominates: 1)? High currents and high voltages can both be present, but perhaps not at exactly the

This shows 600 kv per centimeter: http://polymerdatabase.com/polymer%20physics/Dielectric%20Strength.html The Nov 1996 QST article cites the 1994 ARRL Handbook as stating teflon is good for 1 to 2 kv

Hello Jerry, The most conservative dialectic strength I’ve seen for virgin Teflon is around 20KV/mm. My 0.1mm Teflon dialectic will be just fine for a qrp loop. The upper end I’ve seen on the spec

Kurt, Yes, more than 2x the calculated skin effect depth would be best. But have a big roll of foil bought for EMI use that is only 1 mil thick, and would probably use that. A skin effect depth of

Rob, I assume that it is copyrighted. However, I don't believe that any of the lessons ended up referencing it, so you are probably fine without it. It is a great resource and well worth the purchase.
