Realistic DX-150B Receiver Part 1 - Repairs (Ep.235a)

[@papabear1417]

Nothing is fixed in 5 minutes. Time is experience and experience takes time. These videos are contra to the instant world we live in today. Chapeau Trevor

It feels great to know that everything is peaked for the best signal, no matter what the radio.

[@Poppinwheeeeellllllieeeeez]

Tweaking trimmers and diddling inductors for hours on end is always enjoyable. Time just evaporates.

Hey Trevor, I have and occasionally use a DX-160. With a nice piece of copper in the air, it does ok. I ain’t been inside it yet except to poke around and my SDR runs circles around it of course but, there is something about the twiddling of knobs and skimming the bandwidth that keeps the old set alluring. Thanks for the tidbits. I’ll put them to good use someday.

Hi Trevor, I suspect that these large plastic wheels for the tuning have shrank. It seems it is made of that same plastic you sometimes find cast around steel axes, and there the plastic shrinks and then breaks because the steel is not shrinking with it. That would explain why the springs for the dial cords were flat out, and why the tracking was often off. And for the hum, I think I noticed that it was 50Hz (or 60), not 100Hz (or 120) on your scope ? And when I heard it the first time it also reminded me of a hum caused by a short, so my thought was that one of the diodes or caps parallel to them is bad. Still, you removing that one cap in the power supply made it really work a lot better, so.... I am in doubt. Nice receiver....

[@petermetro4686]

Bridging C71 with another cap reduced the hum. Could it be that adding the higher value was correcting for a faulty cap? Was the original checked for spec? Great video, thanks

[@TrevorsBench]

None of the caps I pulled out have failed entirely, they just were out of tolerance by a huge margin. It was definitely a design error.

Selling?

[@TrevorsBench]

Yes

[@discow00t]

5+ minutes with an intro plus fiddeling with knobs (part of every video) + 25 minutes of alignement and tweaking can be left out. I stopped watching, only to find out there is a part 2 🤨 Your videos used to be more informative and entertaining.

[@TrevorsBench]

The alignment is the most important part of this receiver's recovery. Too bad it bored you

[@discow00t]

@@TrevorsBench agreed. But this process can be seen in numerous other videos. It's far from boring when editted down to a couple of minutes. Like with many parts of your videos.

STOP SPAAMING WITH 2 VIDEOS !

[@a.f.1587]

STOP BITCHING ABOUT THE VIDEOS. You doing this under every video, do't watch it if you don't like it.
