Great video, thanks from England

Did you ever upload the manual? I just ordered One of these from eBay in unknown condition other than it powers on and could use any information your willing to share!

Excelente!

Turn this generator to regenerative receiver.

From inside is sou ugly

lot of car devices had "grandpa of Pi/Arduino, Motolora 68332 microcontroler based on 68020. Do You know what software theryre running on?

Dear Jeff, if possible, I would like to receive the Signal Generator Heathkit IG-42 manual in PDF via email Thank you, Fernando - Parnamirim - RN - Brazil..

Your presentation was very informative, I remember the CB Radio craze I was into it Radios, Towers and Mic's. D104 and the "Screaming Eagle" Radio with a set of "MoonRaker's " thanks !

FWIW, back in the late 70s, there were two major chip-makers with "MOS" in their name; MOS Technology and MOSTEK. In my world at the time (electronics/computer engineering) everyone I knew or heard from (including the people at these companies who would answer phone calls) pronounced them as "em-oh-ess technology" and "mahss-tech". At least in my own experience, it has only been in more recent times, when a lot of people who were not in that industry at the time, or where simply too young to have been involved, have come up with different pronunciations. Kinda reminds me of electronic hobbyists these days who say "Jam-ee-co" for Jameco Electronics, because that's what it looks like and they were not around back when that company as called James Electronics and know to call it "Jame-co."

Are there any Transistorized Q multiplier devices?

I built many of their kits . . . test equipment/audio/RC/TV's. My scopes and meters still work after 50 years.The Heath TV's were excellent, I built a 25", 13', and 19' before they were bought by Zenith. When that name went on, the quality went down! Our 27" Zenith came with all the boards and harnesses assembled in Mexico . . . not as fun a project or with the quality components of the Heath sets. On first power up, it kept blowing the circuit breaker. On examining the schematic, I found that the power supply harness was assembled wrong. The Tech at the Heath store said they had a whole production line like that causing much headache!

Very Well presented Video!! Clear and precise explanations. I look forward to other pieces of Ham Radio Equipment you may take the same approach with. THANK YOU!

Can you test it without an oscilloscope?

M3 encanta esa radio

Great Video thanks OM 73 KE4EZ

Where is the speaker? Oh wait, that tiny little thing? Dang. I'd rather have the tube version.

The 2024 price for 1940 $34.95 might have been overstated. In 2024 $, this radio would be $745.

Awesome !

Thanks for that thorough report. I bought my SA-5010 about 40 years ago and it still works perfectly!

Thanks, great video. I have three XR-2 Healthkit radios. My first radio didn't have any knobs. So, I purchased a second one to get some knobs. Then, I made more knobs for the other radio. Afterwards, I saw the third radio at a swap meet for $10.00. I couldn't resist, so now I have three XR-2 radios.

Very good

Great video. This should be a template for tech videos on UA-cam. No stupid background music, no waffling about unrelated stuff. Just the facts

Hello, I purchased a board from Scott, all the parts and I am ready to program the chips. The folder pld-wincupl has 3 files. I will only need to use the eta3400.jed file, right?. Will the program wincupl work with the XGecu PRO T48? Thank you!

Thanks Jeff!

Nice work! I would love to see a tutorial about how you added this functionality to MAME. I am interested in using MAME to emulate a simple vintage embedded system, but was unable to find relevant examples or adequate documentation.

Awesome! I asume having the RS232 interface and a terminal was quite a luxury at the time!

Wow that's great! How well does MAME handle the 7 segment display? I've played games like "Asteroid" on other emulators and it didn't work well because the simulated display didn't fully emulate multiplexing properly.

Another awesome video. Thank you for sharing this info. I love learning about these old kits and you always provide an amazing amount of interesting details.

Why leave the selenium rectifier? isn't that a ticking timebomb?

I remember my parents had this exact radio when I was a young kid in the very late 60’s & very early 1970’s! As my dad got the exact radio second hand & got it working & we listened to lots of good tunes through the radio! Man great memories!!🙂🙂

I had no idea that MAME could do that. Cool!

I have the HD-10

Would disconnecting the antenna from transmitter potentially harm the transmitter without proper loading?

Modern solid state switching eliminates the need for hang time.

Very cool!

Thanks for this video. Just bought an HW-101 and getting back on after 35 years.

Very cool! Liked and subscribed!

Great advices. I did restore a reel to reel player - as in changing old belts, new cogs on trip counter. But I didn't change any old electronical components. It works very well, even if it is from 1969. I wonder if it is safe to use, or it could cause a fire. Not much knowledge on electrical components. 😮

I remember seeing these in catalogs for years but never knew that one paddle was for Dah, and one for dit... I just assumed they were to be grasped and pinched together to make a tone. neat!

Hey Jeff, I've been enjoying your videos for many years. I miss the outro speech you used to do in earlier videos :)

Very cool keyer!

i have two of these in my dads old stuff they worth anything lol i was going to throw them out

Could you list the tubes please. I copied them down but unclear on maybe an a few as the letters sounded close.

ANYONE KNOW WHAT TUBES THE AGS COMMUNICATION RECEIVER USES I NEED A BACK UP PAIR OF TUBES INCASE MY TUBES GO THANKS.

Hi Jeff. Can you use a Lattice 16v8b25 on this? Thaanks

I bought one upon its initial release. It was a terrible reciever that I put on the shelf where it remains today. Maybe Ill revisit the mods that others developed to improve on its design flaws. It was my last Heathkit before they closed their doors.

Ok

Nice restoration of a rather rare now Heathkit AM radio. Handle usually is found broken in the middle. Great 6 C cell battery holder with cardboard protector added . Highly recommend doing that.

Jeff, this is a question regarding the IT-12 signal tracer but I was hoping you could help under this video. Do you know replacement pot details (Mouser etc) that can be used for the level control in the IT-12 Signal Tracer that would allow proper fitment?
