Homebrew Radio

[@N6QW]

Wow what a terrific project! Congratualtions. I really enjoyed seeing your handiwork and can appreciate all of the manhours that went into building the set. Tubes are still alive --and that warm sound is unbeatable! Thanks for sharing! de N6QW

Amazing radio. This is what radio is all about. I can't wait to get some of my grand dads boat anchors back on the air!

[@CarlosGalliath]

That is the most beautiful home-brew radio I have ever seen. The tuning and audio quality is amazing. You are a genius sir!

[@aa1ww]

Just wanted to echo the positive comments below. Really wonderful accomplishment. Thanks for sharing your project; it's a beautiful radio.

[@nocusr]

Gee, I understood him perfectly. Great accomplishment, love the projects in the old Handbooks. 73 N2YEG

@984francis I did most of the chassis layout and all the schematic by hand, these have not been scanned as of yet. Even though I'm proficient with Autocad, I wanted to experience what it would have been like "back in the day". The design is basically a conglomeration of the typical individual stage circuits in the 1948 Amateur handbook. There are several good projects in the 1948 book also. In my opinion the handbooks from the 40's seem to be the best reading for this sort of project.

Great build! Love it ! Great Audio tone !

[@vk3aqz]

Excellent project. Good clear narration and explanation. Well Done.

[@mikelee8520]

I have a Yaesu FTDX401 and I tell you the audio is superb on that, you cant beat the old valve radios. Well done on your project, very nice indeed. M6YMN

I built similar receivers back in the '60s and wish I still had them. Those I didn't sell were consumed by fire when my shack was destroyed in '76. You did a magnificent job on this 'labor of love' and an outstanding job of presenting it as well. I assume by now you have the IF gain problem corrected so the AGC is working correctly. 73, de Mick - WB4LSS

Отличный Приёмник построенный Квадратно Гнездовым методом ! очень правильное решение !

[@TAC19jm]

This is a wonderful radio!!!

[@Satchmoeddie]

So you built this from the 1948 ARRL handbook? Out-f'ing-standing! I build really simple stuff like guitar amps, with comp limiters, & multi channel MOSFET switching effects loops, & lots of analog audio signal processing & a little DSP. I just passed the Technician & General Class exams last week. I have loads of spare tubes, transformers and I do still have some larger variable caps than those floating around somewhere in my collection of crap. I have some military power transformers that I thought I would never use due to the high voltages, but I found some Telefunken EL156s, so, those might wind up doing an audio project too. I think I have a massive 1.8KV CT that I may multiply the voltage on & use with some 4-400s for a HF linear amp. I use PSPICE & SPICE so much I forgot all the old differential equations for LCR AC circuits. I'll bone up on those, study all the filters, antenna traps, more rules regulations, practices, etc & go get my Extra Class in a couple of weeks. I may try an ungrounded common grid design Xmitter. I hate those in guitar amps, so I might see if I like them any better in something else.

I think it's AWESOME.....damn good job he did.....hell yeah...

[@jonnysocko]

That's quite a radio. Great build.

[@yo8tot]

Great sound. Very nice work !

[@PaulHigginbothamSr]

this is a great radio, good work, I feel the agc should be clipped as early as possible, to reduce gain, maybe even on the antenna tuner.

[@erin19030]

Amazing!

[@984francis]

Superb Work, both the construction and as far as I can see, the design. Are the design and construction details available?

[@combatjm89]

Outstanding!!!

[@nickschor]

Fantastic work! I'm thinking about getting back into Amateur Radio, but am wondering about what to do if I find out that the tubes in my old rigs...(SB-30n and KW 520 SE), are blown. 73's to all.

[@azzy314159]

Wow! Very nice. Where did you get The Tubes, the If transformers and the variables for the gang?

[@RetroCaptain]

Good day Well sir that's a nice set! Much work, but should last 50 yrs use eh!

[@ruhnet]

Fantastic work! 73s

[@wa4aos]

Very well done receiver project. Impressive! 73 Glenn WA4AOS

[@powertube5671]

This is a major accomplishment. I'll bet very few EEs could design and build something like this fresh out of college. I'm in awe! de WA2WHV

[@MickLBrad]

Today's EE graduates wouldn't have a clue how to design and build anything with vacuum tubes! I doubt they could identify the internal parts of a vacuum tube!

[@74wwafer]

@mylowproject They're all hand drawn, I haven't scanned them yet. I made some changes to the design while it was on the bench which haven't made it from the note book to the schematic yet. Most of the overall schematic is made up of the typical circuits in the 1948 Amateur handbook.

[@billhall8003]

Do you have a schematics by now? Would love to see what all was done. Ever thought of doing a video on the schematic and design? I believe it would be a hit.

[@1903A3shooter]

WoW, very impresive, looks great. Dave W4GSM

[@freak55beat]

my god you must be so proud

[@Badwsky]

I want to play with it's knobs! FB Project. I wonder what (if any) dial printer software you used. Those ganged tuning caps are band-switched in as you go down in freq I assume. Sounds sweet. Does the dial glow with at least some #47 bulbs? 73 DE WW2W Tony

[@PaulHigginbothamSr]

I personally thought one tuning cap was for the local oscillator, one was for the IF, and one was for the antenna, so I would not assume changing bands turning down would be cause or use of falling frequency tony.

[@raypsi1]

gr8 job coils are easy just put on lots of taps

[@mylowproject]

do you have the schematics for the set. please reply.

[@AlteSchutze]

Fantastic quality for those times!Respect!de UR5XCQ

[@DG1MJH]

wonderful! congratulations! vy 73 de DG1MJH

[@mylowproject]

@74wwafer ok is it for sale or can it be replicated

[@johncliff996]

Such a terrible shame he has such a bad speech impediment, or is he trying to speak a language that is not his mother tongue. I am having a great deal of difficulty in understanding him. One can tell he did not go to Eaton.

[@cooker4409]

more than likely....Southeastern USA....some accent detected....old southern boy myself...I miss a word or two here and there, but no big issues....hell of an undertaking, I think....and it F'n works....I can't build anything close to this....some small kits....foxhole/crystal sets for MW/SWL/AM/CW....but nothing on this scale/level....damn good job this cat did....thumbs up.
