Test Equipment / Re: FeelTech / Kuman FY6600 DDS Function Arbitrary Waveform Generator repair
« on: December 27, 2018, 08:49:00 AM »
Cool deal. I think I have seen a schematic for that model. I will have to dig around.
I will get in touch with you today on the board. PM me if you do not hear anything. So busy.

Wow, Great job at hunting down the faulty component.
Must have been bad from the beginning.
Thanks for posting this unique bit of troubleshooting.
Using the brute force method like that really helps on the tough ones.
On older gear I use a low voltage battery on the rail. Then start checking the voltage as I move away from the battery.
The way you did it works a treat for those hard to read schematics or no schematic.
Thanks again for this valuable information.

Hi,
Welcome to the forum.
Thanks for joining in here and on YouTube.
I know what you mean about repairing equipment. I hardly get a chance to even see my own.

I think it is the settings I have that does not allow folks to post embedded HTML files. It is a safety feature.
I need to set the board to display for YouTube.

Have you recapped the radio? That is always the first step in a radio of this vintage.
Not saying it will fix your problem but would be a good start.

Hi and welcome to the forums. It is great to have you here.
The 101 is a great radio. To some it is a love hate relationship lol.
I think they were one of the best radios ever produced.
Thanks for sharing and for the kind words.

Equipment Review / Re: Instrustar scope /SA
« on: November 30, 2018, 07:38:44 PM »It was a fair while back Buddy, you asked me to give a report ,on this pc based box, Well the scope or spectrum analyser makers have nothing to worry about. I tried the scope disappointing , then I tried the S/A it does put a kind of wave form up on the pc screen and I'll leave it there. One useful thing it did do was, make me get on and build Hans Summers Spectrum Analyser, not a massive band width, mine goes from a few Hz to around 146MHz, which actually covers everything I need, and it is a proper S/A..
Paul de M0BSW
Hope you &yours are keeping Well
Sorry I missed this Paul.
So darn busy here. Well that is disappointing to hear. Was hoping for a better report on it.
But now you built something that is much better and bet you had some fun with the build. Great to hear that
Doing pretty good here. Thanks
Hope you are doing well.

Test Equipment / Re: Curve tracer project.
« on: November 27, 2018, 10:33:36 AM »Buddy, I built mine in an external enclosure and run two BNC jumpers to the scope. Kind of aggravating though, so in the future will be putting it inside an old scope.
Funny I see there is an RCA WO-33 just like Paul used on eBay. I been watching the price go up to crazy levels for that scope. It would probably have no bids if it weren't for Mr. Carlson.
I was thinking of building a stand alone unit also. Could come in handy.
Yes, that RCA scope on eBay suffers what we call the "Carlson effect" lol. Seems what ever Paul works on the price goes up!.
The Heathkit IT-11/28 have gone through the roof.

I decided I need to trouble shoot the scope to see why I can not lower the volts per division.
From .005 to .2 signal passes.
From .5 to 20 no signal passes.
I have attached the schematic of channel A .

« on: November 24, 2018, 01:26:35 PM »Hi Buddy, I to am a pateron on Paul's site and building this, I just bought a CRO, not had one for years, I think I may actually buy another, they have more character than the DSO's in my humble opinion and I'm enjoying them again.
Hi Paul, good to see you here again.
I agree, an old cro just looks better than a digital unit. I did not give but 10 bucks for this old HP. It only has 500KHz of band width so it was basically useless like it was. So re purposing it to a curve tracer was a plus. Plus I really like the graticule display of the scope.
I saw you post on his Patreon page and have been meaning to speak to you there. Just been so darn busy here.
Thanks for stopping in.
