Thanks Frank. There are problems with the generator due to the SMPS that is used. And that is high level AC voltage on the output jacks. I tested mine and it was fine. Should be a good series.

Way to go Scott!. They really have their place. And if not worth fixing there are tons of parts inside. Thanks for sharing.

Thanks for the sub!

No problem. Should be a decent series.

Thanks Dennis, I think it will be a fun series. Appreciate the comment my friend

Thanks allan. I think it will be a good series of study, and a lot of fun. Thanks for watching.

This was added in video 131 I believe. But yes great point.

They work nice. Thanks

Thanks for sharing that story Doug. Model 30 YOE... I like it. Have you checked your unit for AC voltage on the outputs?

I did a quick measurement Buddy and got 42 volts AC from the hot side of the line to the output connector on the signal generator and 36 volts AC on the frequency counter. Probably something to do with the power supply that they are using. I will need to keep this in mind until I can go take a look at what is going on inside. Thanks for the tip Buddy you could have saved me from a bad situation there. 73 Doug.

Cool test Doug. There is one more I like for you to do. Go to your ground terminal on your outlet and to the jack and see what you get. Folks I have talked to are seeing from 82 to 120 volts. I do plan on another video on this unit and maybe a possibility to eliminate this problem. I do know the current is very low but certain parts like JFETS and FET's are not going to like that voltage.

Thanks John, Yes the Leader is a great unit. Mike from Mikesradiorepair sent me this one.

Good to meet you Kevin. Sounds like you already have plenty of background so learning RF should not be an issue. I will do this series in the same style I do all my videos. A lot of material to cover. May even see if we can get Mike and a few others to chime in also. Thanks for watching my friend.

Will be looking forward to seeing the video Scott.

Cool deal Jon. Have you checked for AC voltage on the output jacks? Interesting to know.

You mean 120 volts, or just an AC voltage of any value?

Yes mains voltage. Let me know what you find. Also there are several youtube videos on this.

I'll have to check that. I'll get back to you.

Thanks. Have you checked for AC on the inputs yet?

Thanks for watching

Dino Papas If it weren't for ebay I probably wouldn't be repairing radios now. It quite simply is one of the best resources there is for used equipment. Actually it's a great resource for everything you need. Equipment, tools, service material, training material, supplies, radios and the parts to repair them.

Thanks Dino. Yes cheap is the way to go for the hobbyist. At least until he decides to stick with it. I have seen those generators you mention and they work ok. Waiting to see if the Chinese are going to make one for 50 bucks:)

Don't you love it when family moves in? lol. Should be a good platform to start with. I have this 25, a 29 and a 148 I will be using for the series.

I never use much over a 100 MHz scope. For cb and HF it is all you need. CB is a great platform to learn on. Remember it is all radio just cb is a stripped down version of it.

Thank You for your insight and encouragement. Gotta respect that advice :-) I really enjoyed watching your Kenwood TS50 series. That was a work of art. 73

Yes, Wish things were this cheap when I started lol. Appreciate the comment ole friend. Thanks for watching.

Thanks Joel. Looks like you are on the way to getting things set up.

Hi Nik. I plan to do just that. Will start with an introduction to the radio so everyone knows their way around it. Then move to basic fault finding and then alignment. Thanks for watching.

I agree, and wait till we start using the curve (signature ) tracer.

Signal generator yes, To inject the signal , But a scope is also a must if you want to see the recovered signal waveform .

Hi James. That is what I intend to do. Next upcoming video will be an introduction to the radio circuit. Showing the block diagram and locating the blocks in the actual radio and schematic. I did this on a website years ago and was a hit.

Me too, I've been slowly working through some simple repairs and have a basic grasp of schematics, but sometimes I get lost, then Buddy ends up making Video #126 with my radio ...

Yep, that glue got another victim. And you are right. Have to crawl before you walk.

So true.

i would suggest if if you want & love to do this kind of work'''''first start taking on line (beginner) electronic courses''''''''a few anyway'''''''then start educating yourself''''that way you get the basics of electronics before you 'dive' into the 'real' test''''then thats when the ''real fun''starts''''as you go you will learn that you should had done this '''years ago''''''''OUT OF TIME''''TUNE IN NEXT TIME''''''''JAMES.H''''OKLAHOMA.

''you nailed it ''james''''.

Thanks

I would be careful with tubes rigs but yes you can use it for that.

The 1801 is getting pretty old. Sounds like the crystal may have drifted out of spec.

steve that is a good question. Also Jan is out of it. There is a place that is called Kens crystals but I have never done any business with him. Let me shop around on it.

Working on that.

It is really not a bad unit to have as a hobbyist. But if you are into more professional repairs Then find yourself a good used Tektronix, Agilent or a new unit like the Rigol.

Thank you and yes I have a hp 8657b signal generator 100 MHz counter and 100 MHz scope but I need something for transmitter allignment and was tryin to get some ideas .

Thanks for joining in. Mikes a great guy. Actually there is a cheap one. I have heard good things about this cheap unit. Just put it in a box and add jacks, attenuator, switches. Will post the link below.

You are right William. I thought I had mentioned that in the video but it may have been edited out. I seen those videos and how one guy built his own supply board (linear) to fix the issue. I did test mine and the voltage on it is nominal. Had to do that before connecting it to my new scope!! Thanks for that concern. I will mention it in the next video.

I was thinking of purchasing one - but did not know if the problem had been fixed on the ones being produced now. Would probably damage equipment and body if not fixed. Thanks again for the informative videos.

I will put it in the que. Thanks for the suggestion.

You saw it as I saw it.

This has been asked many times over the past 20 years. When I worked for a General Electric land mobile radio dealer the manager had a license on the wall that we worked under. I do remember looking at it before I left the company it had been expired for 3 years. When they went out of business a local guy that was the tech bought out the business. Works on local state emergency and law enforcement radios. To my understanding he was never licensed. When I started at the EF Johnson service center the owner had no license at all other than state related stuff. I Google this when I saw your post, still no real answer was found. I did read about cb and there was several statements, one saying you had to have a "First class license to work on a transmitter, Then further down stated all internal test and adjustments had to be done on a non radiating antenna. So with that I am not going to say either way until I further investigate it. Good question.

The Radio Shop Thanks for looking into this! I'll be interested in what you find out...

I hold the GROL (incl MROP) PG, Radar Endorsement, GMDSS Op/Maint DB, and the Radiotelegraph T (Formerly T1) Licenses. These constitute the 6 commercial FCC licenses still in existence. I passed all 6 required exams in the past 2 years (also have the Amateur Extra) and the only types of radios these recent study materials and exams covered were the Shipboard, Land Based Stations communicating with said ships, Commercial Aircraft and ATC Tower radios. These 6 licenses were intended to allow repairs of these radios in any location. We were told that while at one time, all AM/FM/TV broadcast engineers and stations had to have the GROL, this is no longer required due to the reliable automated shutdown systems in place nowadays. There was zero discussion in the material (G. West et al) about any other radios so would have to assume those are not required. I was told that I am one of less than 20 licensees in the world with all the licenses so thought I'd help answer. Love your videos! Regards, Jim AA1JV

Jim, thanks so much for that information. And congraz for holding all those tickets!

Hi Slim, That would be something eh? A cheap Chinese signal gen that covers to 1 GHz. You never know about those folks. Thanks for watching.

ha yeah. but I was talking about that beautiful IFR1200 Super S communications service monitor you have there. That is one nice piece of gear

Oh yeah. I love the 1200 Super S. I do have a plain 1200 also but I need to do a bit of work to it. Several problems have come up in the past. The parts are not cheap either. 200 bucks for a resistor dummy load about the size of a dime. Will get to it soon I hope. As always thanks.

Yes that stuff is really hate on electronics. You would think by now they would stop using it.
