I had one got it for Christmas 1972 KE4EZ

HYBRID with 2 EC88's for the RF Output stage in push pull.

I am ok with working out the size of the secondary to get the resonant frequency I want but the antenna coil? What is the inductance to aim for??

I have a few black beauties, but they are 0.066mfd would that be suitable for a bypass cap?

My parents bought me a Hallicrafters S-38C receiver for Christmas in 1953. I was 12. I got my novice ham radio license in 1956. Been licensed ever since as K2QPN.

a great fine tnx mike kg6mn

Thank you for the great video. I lived in a small provincial city in Japan in the 1960s and 1970s. I wanted to build my own radio back then, but the electronic parts store in my town only had those slow germanium transistors. I have memories of wanting those high performance 2SC372 and 2SC373 used in magazine articles.

The 88mH chokes were inserted into each wire of the underground telephone line at 2000 yard intervals. This was done to counteract the capacitance between the wires and obtain the 3kHz or so bandwidth required for telephone speech. The bandwidth could be improved by inserting 44mH chokes at 1000yard intervals. This "loading" as it was called was used in multi-pair telephone cables. Overhead telephone wires on poles with arms and insulators had a very wide bandwidth and comparatively low losses as long as the insulation resistance could be maintained at a high value. Something very similar was used as antenna feeders at short-wave transmitting stations.

Thank you so much for taking the time to tell the story of the Unelco I got my first receiver on Christmas at 8-9, an SR-22R and an isolation transformer. I can't remember anything about the Unelco very interesting and your review of the circuit peaked my interest. WW-II Military surplus was my godsend in those days.

I remember using spring loaded laundry pegs glued to a board for wire clips. It did the job, with tacks. So long ago, now am 72. Thanks for triggering my memories.

Great video! Thanks!

This reminds me of the transistor BC, SW tuner board assembly, I bought back in the later '60s from Lafayette. All it needed was to hook up a 9v battery and an audio amplifier to have a 2 band AM radio.

Thanks for the info love your videos

You allowed no comments on the video but now OK? Can you turn a receiver upside down to transmit?

"Sink the Bismark" isn't 'ham' but the ending has a guy send like two characters in morse ant it explodes into a super patriotic manifesto.

Phenolic PCB's, with either tubes or transistors, my teenage years. I remember when transistor radios would be sold with a couple of dead transistors soldered to the bd so they could call a 7 transistor radio a "9 transistor" radio.

👍 Very nice Mike. Thanks for sharing.

Great Video! I can't wait until you work on the GE transceiver.

I got one of these for Christmas as a kid. I added an power supply (filter caps stuffed into the battery compartment), signal-strength meter (poked around with my Olsson's VOM until I found the AGC signal), and a trimmer with a Radioshack vernier dial for the oscillator. It was a good learning experience, although I was still envious of my best friend whose family had an SB-310.

That would be such a cool present for a 60s/70s kid! Imagine the dial filled with foreign and mysterious signals, luring you into the future.

Part it out, lots of juicy parts in there.

I have to say in my opinion as a truly completely amateur amateur, everything you make is aesthetically ideal, ugly or not. One man’s poison I guess :)

hahha breadman from albany area... hahhahaha miss the 06.

comment for the unelco video.... i have to stop watchin the videos OM... i want every dang regen and normal RXers you show. hahahhahah love that unelco looks to be a fun lil radio... 73 2WVO.

Excellent, Mike! I'm glad I caught this series. Very similar to my Kenwood TS-830S. I am psyching myself up to do an alignment and put it on the air after not doing anything with it for 5 years while I pursued other interests. Probably won't need much work other than replacing the caps as it is in almost pristine condition. I would really like to see you do an alignment on an 830S as I don't want to do it "alone", given all the high voltages present. Your help and knowledge would be greatly appreciated!

Was this a video about mounting a ham antenna on a Kayak? NO it did not make any sense! But I like the demo on mounting a holder for your fly fishing rod.🙂🐟🐠🪰

At first I thought it was going to be an Antenna mount, but yes this would be a good idea for the rod. Maybe put a beer holder there as well, and while watching the video I thought I had an insect on the screen and when to wipe it but he was in the video haha.

I was hoping for an 80 to 10 screwdriver antenna for kayak that I could use on my canoe. :)

1SS86, the performance of ultrashort wave band is much better than 1N34A. pls go to my main page.

Doesn’t get much more bad ass than that…and it’s out of essentially junk box parts. This is real ham radio right here.

Can u really load that flyrod up on all the bands? Does the line wound around the reel give enough inductance? Hah! At first I thought you were mounting an antenna on the kayak; you couldn't possibly have any other interests outside of ham radio, huh?

Did something similar with my 10 ft pelican .i put a standard rod mount in just behind my left shoulder turned in such away the rod hangs out bound and forward .just so i can see the tip by looking to my left and in easy reach if i have to grab it .good for trolling an doesn’t interfere with paddling ,and is much cheaper than a fishing kayak.caught a large mouth bass july 4th weekend @grand lake stream ME works well.

I thought you were going to use the mount for a portable transceiver antenna mount. Fishing is a good addition to your channel. 73

I use Scotty products on my boat as well. All have worked great!

dang it! i thought the video was you taking the scotty receiver you repaired out on the kayak!

Those toys propelled me into an electronics's career, ham radio and a general fascination for science and technology. At 67 I'm still building stuff, buying parts and trying new stuff.

It's amazing what desperate times can come up with.

Running the nearly unanimous comments.. part that sucker out

I bought one of those Archer Space Patrol base stations in the early 70's. I remember it was almost $30. The Radio Shack was just a block from my house. I had to call my dad at work to get his OK to buy it as it was from my earnings. My friend carried the batteries and I carried the radio home. Finally got my ham ticket in 1984. I also got a 100 in one Science Fair kit for Christmas one year. I had the one tube AM P-Box kit also.

У кого есть панорама сразу скажут вам что у вас не подавленная вторая боковая полоса

What a great project to make !

There is a time for everything, even in electronics: a time to restore, a time to dismantle; a time to die so that new can live ;a time for new, made from old; nothing goes on forever, enjoy now by parting it out! Can’t wait to see the new….

My Dad and I built a Radio Shack P-box code oscillator together in the early 1970's. He gave me a clapped out Halacrafters S-40 and check book register to use as a log. My grandparents bought me a transistor radio for Christmas 1970; I spent many nights listening to Mystery Theater with the radio under my pillow. And, I was into crystal radios, fortunately we lived across the mississippi river from WCCO's 50K watt transmitter. My wife and kids got me the radio shack crystal radio Christmas 1993. It still sits on my radio shack desk running 24/7/365! and, I sent signal reports to San Francisco and Wainwright, Alberta with that set -ha. Thanks for the great video! AA0QZ

@MIKROWAVE1 I have a diode that I think would make a very good crystal radio. Low Vf and very low junction capacitance. I tried sending a message via KZbin, but you have messages disabled. Drop a comment and I can elaborate. I might throw a set together myself as well. Nice videos!

I remember the CB Base station, had a variation of that one. I still have that exact 150-in-1 electronic project kit. It is now 47 years old.

I've only come in contact with radios with a transformer. Sometimes there are either capacitors or resistors or both on the AC line to ground. They are simply not needed, and I remove them. I then replace the 2-prong line cord with a 3-prong line cord and ground the chassis. No tickle, no surprises, no issues.

I vote for making it into a ham rig. What higher calling is there for some electronics than to be a ham radio?

Those old entry level generators are great if you like exercising the fingers, personally I'm not that nostalgic. Turn that old piece of driftwood into something more useful..

Brings back memories i still have a galaxy v transceiver and early yaesu gear i enjoy and maintain.
