Buddy you have soo much valuable information on radio and love to share it with all of us that I think you deserve the highest recognition. Thank you for helping me with my FT-101 that only had 80 watts output. I changed the coupling cap in the driver to RF output stage and wow approximately 140 watts to the antenna. Yes I used the chip stick to get rid of any high voltage that lingers around first. Now need to look at a TS-830S with low output. No shortage of old radios to repair but I love it....Lyle
Thank you Lyle for the very kind words. I have spent a many of year working on old radios. Now I feel it is time to give to the community. Only because this is a dying art. So maybe years from now when I am gone others can learn from these videos. Glad you are being safe! Good luck on the 830. It too is a wonderful old rig. Thanks again my friend.
Occasionally when I need a unobtanium 90 degree mount trimmer cap I make them from SMD types. Tack on some heavy gauge solid copper wire for leeds and your in business. Modern digital scopes work great if you get the more expensive types. The biggest problem for a newbie is operating it. They can be rather complicated to use with menu systems that run several menus deep. For ease of use its hard to beat an old analog scope. For more advanced measurements the digital scopes hold the advantage. Having both analog and digital here it's hard to say which I like better. The digital has sooooo many measurement features and math functions but then again the old analog scope is sooooo much easier to use.
Good idea on the using surface mount Mike. Being that this is the only DSO I have ever used it is hard for me to compare. I would agree that the more expensive units would work better as long as the user can figure out the menu system. It is a lot for the beginner to take in. But really I love my analog scopes.
You can pick up old tektronix scopes cheaply, they have on screen freq display and also ch2 output fed to a rear bnc, which you can connect a freq counter to.
That is the truth. Heck here in the US you can get them close to nothing. My two 2235 scopes costed me 50 bucks for both! Now they do not have on screen but that is OK with me. Rock solid units. Thanks for your comment
Great video Buddy it’s awesome that you take time to answer questions of subscribers. I have couple questions myself but I don’t want to take up your valuable time. Thanks 👍👍👍👍
And the 520 being a "hybrid" I feel adjusting your drive you can quickly find if something is happening. Because you are more familiar with all aspects while tuning up. Not saying you SHOULD but they can handle an swr that cripples solid state rigs. Thanks Buddy keep repairing Kenwood Thank You
Another gem of a video Buddy. I have a Tektronix 2220 scope here that I dearly love. I got it in trade for a HQ-170 receiver that was a junker for parts only. The scope works great. Wish I could find a manual for it though. Thanks for sharing this with us.73 DE K7RMJ Frank
I use tenna model 72-2580 30 mhz scope works well . I made a var. rf tap witch i use on my kenwood to keep an eye my output. good to know about the ft-747 love the vidios ricks radio shop
I wonder if thats a similar problem with the FT-757GX series as well.......I have one in the junk pile somewhere that a bloke gave me with a similar fault description.....he said I could have it, but I haven't gotten around to looking at it yet.....must dig it out one night this winter for a look
I hope the supply of surplus Tektronix CRT type scopes doesn't dry up in my lifetime Buddy cause I just cant stand the modern TFT displays. Luckily we don't often have to replace them so I think I will be OK. I always keep my eyes open for a low hour Tek scope when they come around just to have a spare or two around. Still the best in my book. Really enjoying the Q&A vids. 73 Doug.
Thanks Doug. Yes the Tek stuff is really great. Do not think we have to worry about it in our lifetime. Lots of them out there. Thanks for stopping in.
Buddy, It is a typical Yaesu disease from that era. I use a 707 line up as my main rig (the one that has the separate digital VFO unit) and it had similar problems. Once mitigated these rigs 'keep on keeping on' and you'd be hard pushed to rival them with the newer 'do-everything-including-launching-the-space-shuttle-rigs! I have the rig, VFO, antenna tuner and the PSU-speaker unit, and I will be very sad if I ever have to part with this rig! 73 Paddy
very very nice video ....thank you a lot i would like to ask you if you can make a video how to eliminate the output noise of a switching power supply btw great video again and keep up the good work
Well, The problem is not lighting. In fact I can turn it up and completely wash out the display with the internal light. It is more of the design of the LCD that they used. Thanks for you thoughts.
Well it must be something, there are a lot of other videos showing that scope and they appear plenty bright and easy to see. I'm not really a fan of the dark red traces though.
Great video. I've been looking at used scopes. I'm nervous about buying used off of eBay. I found a Siglent SDS1102X 100MHz. Do you or anybody have any thoughts about this scope? This will be my first scope. Thanks!
Hi Buddy, Would you have any suggestions on mu dilemma. I have an analog volt meter that I left the batteries in too long and the build up of that green crud is thick. I used baking soda and water, got it to work a little and then it stopped. Can you help... Angelo
baking soda and water just neutralizes the contaminate. What you need to so is make up a salt and vinegar solution like I did in video #40. This will remove all the crud. Then use the baking soda and water to remove that. Hope that helps Angelo

You are very welcome William.

Buddy makes me glad I own Kenwoods both the 520 and 940s but I bet there are problems with them also.. good video
Thank You
Not much on either of those that cannot be fixed. Specially the 520. Great rigs not like this cpu controlled ones of today.
And the 520 being a "hybrid" I feel adjusting your drive you can quickly find if something is happening.
Because you are more familiar with all aspects while tuning up. Not saying you SHOULD but they can handle an swr that cripples solid state rigs. Thanks Buddy keep repairing Kenwood Thank You
I always loved the detent main tuning dial on my FT-747; made it nice for operation in the RV when rolling down the road. 73 - Dino KL0S
I do like that feature in the 747. Makes for smooth operation. Thanks for stopping in Dino.

That 2220 is a great scope. Should last you a long time. Thanks for stopping in Frank. I will keep an eye open for a manual.

Cool deal Rick and thanks for sharing.

You may just be right. These old trimmers do go bad.

Thanks for sharing Paddy!
very very nice video ....thank you a lot
i would like to ask you if you can make a video how to eliminate the output noise of a switching power supply
btw great video again and keep up the good work
Thanks Nik. Yes I can look into this for a future video.
Time to up-grade to an FT 757 GX or 767 GX.......
767 is a good rig, not that I do not like the 757. What is bad about the 757 is the unobtainable chip.
Could you put a brighter back light in that Owan scope?
Well, The problem is not lighting. In fact I can turn it up and completely wash out the display with the internal light. It is more of the design of the LCD that they used. Thanks for you thoughts.
Well it must be something, there are a lot of other videos showing that scope and they appear plenty bright and easy to see. I'm not really a fan of the dark red traces though.
Mine is the PDS6062. The ones on youtube are the SDS6062. Which is a much better scope. I think I have only found 2 videos with the PDS6062.
Ps. great video again...
Thanks!
Great video. I've been looking at used scopes. I'm nervous about buying used off of eBay. I found a Siglent SDS1102X 100MHz. Do you or anybody have any thoughts about this scope? This will be my first scope. Thanks!
Thanks. That scope has some pretty good reviews. Never used one myself so cannot really give you much information.
Jimmy missed my channel...
Sorry about that :) I will be sure to tell him to watch.

K - Thank you Ill do that...
I too have a owen scope its worthless, I have 4 other scopes i use I should get rite of it
