I've had a SB-102 since I made general back in 1971 and have made soooo many contacts with that old rig. Now it does not want to xmit and receives 'fair'. I think this sounds like a fun project, although ambitious in scale. Thanks for the video. WA0ZMF

Now THAT brings back memories. My 2nd HF rig was an SB-100.

I have one SB102 I'm needing to recap and a SB 104 too... What is the better product /way to clean metalic chassis ?

She's handsome

Very impressive restoration workmanship. You are clearly very capable, determined and patient. The idea of using colored heat shrink tubing to accomplish multicolor wire coding is great. Thanks for sharing this, and congratulations on a beautiful job!

A man with more courage than me. Several years ago I did the same thing with a Heathkit DX-100. Making the new wiring harness proved to be a nightmare, however, I did finish the restoration, and when I brought the rig up on a variac, the HV capacitors started arcing to ground. This was my fault because I had used the original filter caps. I could have replaced them, and I feel that the rig would have been fine. However, I lost interest, and the rig never got on the air.

What a beautiful job.

I appreciate the valuable time you spent providing your presentation about restoring reliable Heathkit SB-102. I will receive the SB-102 tomorrow via UPS from California. My primary goal is to overhaul the components, such as resistors and electrolytic capacitors, check the tubes, and pay close attention to wiring and solder joints to ensure they are solid. I hope to see the chassis with a 400Hz crystal installed. Then, I expect to go through an adjustment procedure to bring the unit to full specification. My concern is the plastic pieces for the dial, which I learned were fatigued and brittle due to age. I must be careful to remove it and use a can of plastic coating spray to reinforce the back of the dial assembly. It will be a tremendous challenge for me to work on used conditions compared with my years of experience with Heathkit assembly when it was new. Thank you for sharing the information to help me.

Just WOW!

This was my first rig. Worked hours and hours of CW on it. Dennis ..KB4LSX.

congratulations just like new, I have an SB101 and it needs to be restored, your video is motivating, 73

Excellent Kevin! My SB102 works well enough so I doubt I'll try your level restoration but will certainly remember your sharing information in case I ever try it. Thank you for sharing.

I built a brand new SB101 in 1968 and used it for quite a number of years. It was a terrific radio, and connected to my Classic-33 Mosley tribander beam I was able to work the world with it. I ran hundreds of phone patches to soldiers in Viet Nam over nights in the summertime. I was one of the louder signals off the West Coast, no doubt due to our elevation. Years later I bought a used SB102 and it was also a great radio. And finally I located a Collins S-Line transmitter and receiver for sale, and I will say, the Collins gear was just heads and tails superior in every respect to the Heath... but the Heath for the money was spot on. The Collins stuff was truly a dream to run though.

Hello, do you have the complete SB-102 Assembly And Operation Manual, please? Every version I've come around online is missing pages 2-87 (which I need). Thank you!

Did you have to replace any of the tubes? Is there such a thing as upgrading tubes to equivalent transistors?

Hi Kevin. What part# are those LED's? I did a search on eBay, but not sure which ones. I see some turn signal LED that have a bayonet base... Also, did you do a cap replacement? Do you know of a source for replacement caps for the SB-102? TY! 73

I used to have old Heathkit transceivers years ago. The agc was always to fast for my liking, so I would add a capacitor to the agc circuit to slow it down and add more hang time. That really makes them sound better (to me). Nice stuff

Two possibilities for the chirp come to mind. The function of c320 and c321 and associated parts is to prevent a "pop" when going from transmit to receive. You may check those parts out. Also, the relays and their sockets can develop a coating that you can't see that can cause all kinds of weird problems. Using an electronic solvent on Q tips will remove the film. The alignment procedure talks about adjusting the heterodyne oscillator to zero the s meter from band to band.

Did you get rid of the chirp??? If you didn't, did you try with another keyer, or just shorting out the keyer wires ? Does it happen when you tune on cw?

Wow, just wow!!! My dad had that radio when I was just 13 years old, got my novice at 14. I remember playing around with the load and plate current, lol! 40 years later and hear you are a 3 year ham, well maybe 6 years now, lol I praise you brother, I was a radio tech in the MARINES, studied electronics in high school, avionics in college, and with all that training the most I've done was make my own antenna, a delta loop, with a 9:1 transformer oh and my own 460 ohm ladder line , no comparison, definitely not! Awesome job, love the L.E.D.S ! 💪👍🙏 N3WUB

Great job!

that's a kickass AT-Coupler. Respect

Sweet!! Nice job!

Fantastic 👍🇬🇧🇬🇧❤️

Really enjoyed the video. Making a transceiver so it was very interesting for me. 73

in the 70s i was the first kid on my block with a 150 watt motororola mocat 20 20 C/B radio thanks to heathkit my neghboros TV went goofy every time i keyed my mic

kid nowadays need projects like this instead of those god dam video games i looked a long tome to find a simple sringboard project kit for my son at 13 he loved it i found a crystal radio kit once i can see his face with a shiteatin grin i came home from work HEY DAD LOOK AT THIS IT WORKS WITH NO BATTERIES i said good job we need icecream

as a kid my cousin built built many Heathkit S/W radios he knew the moris code to get his ham licence my dad got me many heath kit projects i built all H/K R/C i still have everything in working cond & a servo simulator i never built at 18 i went to work for motorola in 1977 my cousin went to work for Moog his name is on the blueprints of the minni moog synthesizer all because of heathkit he's a retired engineer i have a master electricians licence

bang up job, 73 and gud DX de kb5hxt

“Now get up and get in it it’s yours.” Joking or not I didn’t care for the comment. I can imagine how bad he w wants to get up and run to it but can’t. What a jerk.

Very nice job Kevin.. I hope you have a great time with your NEW SB 102 73, Glenn WA4AOS Laurens, SC

Can you tell me how you connected the SDR and what parts you used?

Hi Kevin, how do you stop the stepper motors from turning the roller inductor past it’s endpoints? Do you have micro switches or something?

This is great! I have a FT-101f, Can you tell me how you connected the SDR and what parts you used?

Kevin that is a very nice job done!! Do you have a list and source for your capacitors and resistors that you replaced? What process did you use to clean the circuit cards from dirt and old solder? Did you replace the hardware for the circuit cards too? If so what did you use for replacements?

I take it this setup only moves the tuner to predetermined positions? No automatic tuning based on reflected power?

Will he be able to drive it tho with his condition?

Very nice job looks fantastic.

A fantastic restoration Kevin, very nice indeed. I have an SB-102 I pan to do exactly the same with. Just saving it for retirement in a few years time. Most important now is to get on the air and use it plenty. 73.

hey can you tell me some of the parts you used?? like those roller inductors what value are they and what amperrage?? very interested in building one likre this minus the rasbery pi i just want to run it to a pc and run software from my pc with memmories ,... also is the tuner tuning from programmed memmories that you found and saved yourself? or is it actually searching for the lowest swr? i got the number off the jennings capacitor ,... those are mighty pricey i don't think i will need one that high in wattage but the range is awesome really nice job you did and i understand most of it just would like to know where you got the inductors from and what values they are thanks for posting this --- annother ham :-)

Keep your head up.

How did you measured the SWR. I tried to build also a automatik tuner ;-) Chris

If Thats His Favorite Car........That Is Hella Motivation For Him! Good Shit Guys! I Got Him getting Up Getting In That Shit Soon! Get Well Soon My G!

Am I missing something??? HOW THE FUCK IS HE GONNA DRIVE IT??

Littt

WOW! How about publishing something or selling your software/configuration. I want one! mark KI4Z

GLORY!!!

Get that camera outta his face

hes so happy, my sister surprised me with a 2006 charger rt hemi a few months back. and I love the car. enjoy it man! chargers are fast and great cars to drive.

may this man be forever blessed
