Я ходил немного дальше, собирая подобную схему на радиолампах прямого накала. С реостатом в цепях этого накала, литцендратовыми катушками и вариометром... Это были лучшие дни жизни.❤
Nice work! I'm working on a 1v2 regen project now that will use a 12AT7 and 12AU7 at 24 volts. I'm going to use plug-in coils to tune the bands...the great thing about plug-ins is that I can make as many as I want for different frequency ranges. Seeing your project motivated me to get mine done. Ed AE7TE
Simple, low power consumption, light weight , and works well in my solar power system. Does throw snoopy folks off , as they never seen such. Nicely presented. And I snag my swl cards on my rig. Tks de kv4li
thank you I have learned about regenerative here and AA5&B's web site and will enjoy reading - I love his description of it seeming to suck signals in from the "ether", as it's that type of feel-vs.-specs I've noticed so much of ever since searching the white noise for contact
I've always had trouble with the "RF Choke" component. I don't think this is an "inductor" - or at least, when I put an inductor (the small resistor looking type) they always seem to just mutate the signal horribly on the o-scope and don't seem to actually act like a choke. What did you use for the actual RF choke?
Do you think the receiver could get damaged from oscillating with a bad antenna? I just mean from the RF that could get reflected if it starts to transmit.
is the 100 pF throttle cap (connected to the tickler coil) the regen control and the 100 pF (connected to the band switch and main coil) is the tuning control?
I seriously haven't gotten ANY regen receiver based on a "tickler coil" to work worth a damn. The only regen receiver I've gotten to work so far where it seems to function properly (where it "hisses" when regen turned up, and has good control over regen setting, etc) is the "3 transistor short wave radio" based on a colpitts , here: www.netzener.net/index.php/project-articles/15-3-transistor-short-wave-radio But supposedly that one isn't good at decoding SSB and yes I could hear (faintly) some HAMS on SSB but I couldn't ever get it cleared up enough to understand them, so that circuit probably isn't the best for SSB just like the guy's article indicates. A further problem is I live on the West coast of the USA, where shortwave stations are rather faint to begin with, so using that receiver for shortwave is also tough, even though I can get in stations faintly, only at night. I have been pretty successful at getting WWV on 10Mhz loud enough to hear it but on 5Mhz it's always just noise, probably doesn't propagate well enough to get all the way to my location.

Regen radios are fun to fiddle with.
I find I rarely actually listen to anything for any length of time because I want to see what else I can get.

Круто.

Great job there Mate, Very Simple yet Very Good Sensitivity and Selectivity, Nostalgic,. 73s

Wow, that receiver sounds great on SSB!
Awesome, I believe I even heard a snippet of OTHR in there as well, nice work Peter!
Very good job.
i know this is a old post now but would love a better diagram its hard to see in the video. nice work
There is a link in the description under the video
PERFEKTNÍ VIDEO! TNX! Audion se zpětnou vazbou na amatérská pásma. 73!

Good video 73
I Imagine What Could This radio Do In My Room Connected By My Attic Antennas , Ohh, I Would Hear The Whole World
Hi Peter, nice stuff, is there any to get a more print out of your circuitry?
The link to an article & circuit is in the video description.
Is a regen different than a typical shortwave radio you buy?
Yes. Typical SW radios are superhets.
When you compare this to radios you buy at the shops, which one is better on sensitivity and selectivity?
Every idiot can go and buy something in a shop.
Do you think the receiver could get damaged from oscillating with a bad antenna? I just mean from the RF that could get reflected if it starts to transmit.
No.
@@vk3ye ok thanks. That's a relief. I just finished building my own regen kit and im trying to be careful not to fry it immediately :)
Very nice Peter
hello could be more like coils for both bands, the image is very bad
Is there a reason that the RF amplifier is so lightly coupled to the regen stage? Could you get more gain with more turns on the toroid?
+Jefferson Allan Light coupling is good in regens as it improves stability, reduces frequency pulling and allows smoother regeneration.
is the 100 pF throttle cap (connected to the tickler coil) the regen control and the 100 pF (connected to the band switch and main coil) is the tuning control?
Yes
Why is it less sensitive?

RIT ?
WOOW! What A Beautiful Device, I Would L O V E To Have Such Receiver!
I Wish I Could Make Such A Thing ;( Sadly I can`t
Why so dark ?
Because it's night !
