Terry, I installed the K2 kit into my Ranger, without any issues with the kit. But, getting into that function switch is a real bear! It is obvious that Johnson sure didn’t make it easy, with that wiring harness so tightly placed to the switch. I learned the limits of my vocabulary, having to make up some new words to call the Johnson engineers before I was through with it. Fortunately, the 18K resistor in the VFO had already been changed out before I got it! Getting good signal reports so far with the Ranger! :) 73, Chris, N9WHH
I always like watching you work. As an Extra, I studied the theory. Watching you wotk on these radios has given me inspiration to work on the pile of radios at the museum. Now, I'm understanding the theory that was just numbers on my exam. I still think if I worked on the radios before taking the exam, I wouldn't have had to take it 4 times.
Hey Terry, I'm learning all the time. Especially with all your guitar amp stuff. Love this video of the Ranger fix, but I haven't got the faintest idea of what was going on..!🤣🤣 You are so knowledgeable my friend, that I just have to watch everything. Thanks for sharing..Ed..U.K..😊
Basic theory is the same, except the the frequency range is much higher and you're placing your input signal on a carrier frequency rather than out a speaker (well, further down the process.) If you can find them, I would recommend the HEATH training books, and student workbooks if available. Sime even have lab kits with components needed to complete experiments. Begin with the DC and AC electronics courses, then pick up the Electronics Circuits course to establish theory.
Hi Terry. Usually how long does it take you to repair a transmitter. Reason I ask i have my old Kenwood TS-511S in the shop with it power supply. They both need to be recapped and have 15 meters working again. Just a rough estimate. Thank you for your great videos. 73
So the radio had two of those DIODE ART rectifier tube replacements, and you put an original rectifier tube back in one, but not the other. Why did the radio originally have two rectifier tubes if they both weren't needed?
Hi Terry, I enjoy your video, I always monitor your video. Regarding the rectifier, why you insist to install the original rectifier tube? Is there any noticeable different compare to modern silicone rectifier diode? Thanks De Mula - YB1BUL

Yes Sir, you are correct.
Just try finding one of the switches (spare) haha
Glad you were successful.

Excellent! Glad I could help you take that step. I find working on them is very relaxing. Have fun
Very nice install Terry. I am going to have to get me one for my old Ranger.
Thanks Terry. I have the function switch adventure to undertake.
Great repair vid Terry. Thanks!
190 volts on the mic! 😳. Another great video Terry.
Hi, caught a glimpse of your D-104, I have a couple that I need to get working, any chance you could give us a short class on them???
excellent job
Would love to see before and after photos of the recapping!!!
I have a pic of the recapping. Cannot send here. e-mail me

Nice presentation, well done.

Great video Terry!!!
Nothing beats getting 192 volts across your lip on these old beasts when using a D-104 lol!!
Hey Terry, just wondering if you will need to place a heat/IR shield between the rectifier and the pc board?
Nope, have not had any issues so far, If the need arises I will address it
Hey Terry! Do you have an extra one of those switches @ 7:19??
Sorry man, that is a super rare part
@@d-labelectronics yeah, I've been looking for one for at least a year. Tne ceramic switches are hard to find.
Thanks for sharing this info. Man you do great work. Love your channel and Thanks again

Hard to say, I have a sold 8 hr day into this Ranger so far. Problems always multiply
Where can I purchase a k1 module for a johnson range 2
How much is the K-1 relay board and how do I order one? Thanks Richy N2ZD

Awesome stuff!
Nice.

The new PTT module has diodes in the base for the low voltage DC rectifier 6AX5
@@d-labelectronics Ah thank you.
Those diode modules were very cool. Your mod is very cool too.

I never replace parts that work
