Regenerative Two-Tube 40 Meter Receiver - Part 2 Operation

Regenerative Two-Tube Receiver for 40 Meters on the air. Listen to the simple home constructed radio handle CW, SSB and Digital signals in the modern 7 MHz Band. The radio uses a 6SK7 and a 6J5 and is representative of the classic Novice Special type of the late 30's thru the 1950's. This was the beginners receiver of that era, but this one is built for a single band with attention to stability.

I just love what you do with radio. ❤ Keep up your great work. I keep experimenting because you keep me inspired with all the fun. Sincerely, Professor Howard Daniel Rollins III

[@MIKROWAVE1]

Thank you Professor! Thanks for watching these videos! Oh and what kind of Professor? By the way, what comes after Radio Professor? Radio Clergy?

I like it. As a kid I had a Hallicrafters SX-25 I listened to nonstop. When I was about 14 I was asked to help a 10 yo boy build a 2 tube regen kit. When it squealed I thought I had done something wrong in the construction because I didn't know what a regen rig was. For the next 15 years I thought I had failed. Then I learned what 'regeneration' meant.

[@vinceotten129]

I learned a lot just by watching you operate this radio!

[@MIKROWAVE1]

Tuning Regens gives you something to do with your hands other than punching in numbers on a keyboard!

[@SteveHacker]

Absolutely fascinating! I am quite jealous of your knowledge and skills. Looking forward to watching everything on your channel!

[@kargocult]

beautiful work on your HB receiver

[@riottaba]

That's a very nice regen with excellent stability!

[@Bashnja1]

Great video.With a regen Rx you actually get to feel the control over the spectrum unlike modern receivers with multi conversion noise generating devices in them. All attempts to emulate that with sdr radios have become far too technology intense resulting in high cost and poor reliability with the expensive repair that goes along with it. No wonder the Germans were still using regens in WW2. All that was necessary was a savvy operator, something that is lacking in Amateur Radio CBers these days.

[@MIKROWAVE1]

I use a low 40M dipole, coax fed as well as a 100 ft long wire with a tuner. Both work very well on this receiver.

[@riottaba]

Nice set. The first radio I ever built was a regen when I was 12. I had a lot of fun with it. I've built a few since. They work best with an untuned antenna buffer stage and attenuator. Yours is a fine specimen! 73 Alan G0KMC

[@freak55beat]

great , nice vid , good reception, like the tone of the rig to

[@reese1011]

The rig has a very nice tone to it that only a tube rig can do

[@AlteSchutze]

Absolutly clear receiving !Respect es 73!

[@Kennynva]

I am completely impressed...I wish I could build one..I have a 6J6 but not a 6J5.

[@OdisseuBR]

I have a question, sir: are the tubes still in production? Here, in Brazil, I don't know where to buy them. Only imported items and paying a lot of taxes. Thanks. Great video, as always.

[@billpotter9716]

Excellent quality video for 2010. A bit of time travel. Nice. 73 de AB2ES.

[@MIKROWAVE1]

The antenna coupling is a Faraday shielded swinging link on the cold side of the coil.

[@ismaelconde8457]

very good video. Is possible to have the schematic of this receiver. Thanks in advance

[@MIKROWAVE1]

Weirdness Talk - yes! and strangely his was not planned - it simply was on the air and I intercepted it with the radio thus providing color to an otherwise pretty dry video!

[@LZ2SM]

Nice design MIKROWAVE!The sound is pretty clear!I want to ask you how is the antenna coupling achieved here?is it a variable capacitor?

[@stephenwilliams5201]

Less parts.equal less loss, less power consumption. A good pair of Baldwin's best audio kv4li

[@MIKROWAVE1]

The Baldwins are simply magical. Too much audio level for this! Even those old R2 military phones come off your head with a strong signal on the Paraset with no audio gain control.

[@stephenwilliams5201]

@@MIKROWAVE1 yes sir. Army phones were placed on head then advanced to my temple to make control easier. We followed clandestine troops and every ounce counted. that is to say a Regen/xtal controled rig weighed little.even when barely having a colpits osc with a one transistor power amp. We were the life line. Less parts easy fix .tks

[@billellis5516]

Mike, Where do you buy the parts for your projects

[@ObamaTaliban]

I enjoy your video. What kind of antenna did you use? Al KF7DMY

[@jonathan1234ish]

i made a receiver simmilar to yours. with 6j1p,russian pentodes and a ECL82 audio amplifier with negative feedback...the AM stations come lowd and clear but when i get on ssb stations it seems like they are not well demodulated..i can hear them..but i can't understand what they say...like a verry narrow ssb crystal filter..can you help me?

[@jonathan1234ish]

can you zoom in the schematic? 73! YO9IER.

[@DAVIDGREGORYKERR]

What about using Wire-Ended Raytheon vacuum tubes which should be able operate off 25-50V with a heater of 3V

[@MIKROWAVE1]

Ans. on facebook page. Mikrowave1's Radio Resource Page.

[@riottaba]

sweet regen sir!

[@PachydermPictures]

youve got to exorcise the demons!!!! great stuff.... neat little project with a great demonstration! steve- kb2nqn
