loved it, so much information and good explanation

Unfortunately, these radios do not last long; the transmitter burns out after a few months of regular use.

Is this a "Trickle Charger"? Like to leave it on the battery over the winter

The stick theory was etiquette for us non engineering to get a better handle of the bread board. Great vidto thank you 👌

so it is worth to buy this scope?

Paul question Have you come across any Motorola 2N3904 NPN transistors? Second I built a Colpitts oscillator circuit. Used the 2N3904 great clean output signal. Then I substituted a 2N2222 distortion at lower half of the wave. Then finally a 2N4401 distortion both up and down. Thoughts on this?

Just found your video, I am going to look into this, thank you.

There is no ground to the case.

So nice to see you again. How are you doing?

nice

One which owns a TYT should switch firmware to Open GD77. Makes a basic DMR to a beast of a radio.

These are probably chines rip-offs

Great video Can I drive the output to an antenna?

How do you do the master recording? Meaning playing all recorded channels individually and bring them all together....?

I would like to see your work with a camera that has better resolution. This entire video seem out of focus.

I hope your kids know you are awesome! Imagine growing up with an electronics wizard

Hi. Regarding dimensional accuracy, how accurate is this printer, when it prints cylinders, cubes etc.? I am thinking to order this printer, but I found some reviews saying that is not accurate and many report that the nozzle dragging on print. Have you experienced something like this?

Guilty as charged! Thank you for the lesson.

Is this the Pulse tour ? I've got a similar picture mostly red, with the same set of VLs.

what is the frequency rating of your crystal?

This printer is ass

I tap on the interface and nothing happens

Excellent help here man, just what I was looking !🙌

There isno pcb revision number on the pcb, so we do not know what was really tested....

This may be just me, but, does polarity matter on the collector and emitter on an NPN transistor? In other words, can a collector go to a positive source or a negative source (say, of a battery)?

Let's go shipmate

4 years later... Did you ever make a version 1.1? Any second video?

Aren't color codes meant to be read from left to right? In order to read the first resistor and get the same result you gave I would have to read it right to left? The second resistor, If read left to right results in a 120 ohm ±1% resistor, if read from right to left, like we had to read the first one to get the stated value, results in a 10K ohm ±1% resistor? I'm guessing it's the 120 ohm option? It is within 30-40 ohms of values given by various online calculators. It's great to have us read the color codes but you have to show them consistently in the correct orientation and focused well enough to see the colors. You could also read out the colors in the correct order as others have suggested. BTW- it looks like your HDMI cable is haunted, because if cable TV and the internet has taught us anything it's that the only thing that sets off EMF detectors are ghosts. 🤣 Who ya gonna call?

What’s the point of a large LED DISPLAY that displays the useful numbers 1/3 of the “0”?

Turn the radio on

i purchased one 3 years ago I have never used it just two or three times ....today I turn on the unit and the display is faulty, you can see horizontal lines and distorted characters... can these replacement displays be found?

I'm glad this channel is back. For some reason, I guess the channel disappeared. Hope Paul is OK! I wish someone would give an update. 🤔

I love the multimeter when I am running FT-8 so I can watch ALC, power and SWR all at the same time since FT-8 can have a tendency to quit working and must be rebooted. Thanks for the review.

Yep 2 of my wamptek power supplies just died blowing the rectifier I don't think they use the right rating for what the power supply is alledly supposed to handle

Was watching another of your old videos and realized you hadn't posted in a while. Hope all is well with you! Have learned so much off your videos over the years, thanks for sharing your interests and knowledge with the rest of us!

No function/signal generator sir ?

I guess *flashing speed* changes if we change second resistors values _(the 100K ones)._

What would interest me, is it any good for the crystal to be fed a different fruequency into it especially with higher amplitude?

Thanks for this. It was very helpful 😎

I'm fairly new to using a soldering iron for stained glass and well, I have already ruined the tip by sanding it. Live and learn.

Another excellent video. I really enjoyed all three, very helpful. Thank you.

Really great video. About to do my first amp build, so really liked your play x play extra info. Do you think there is any concern for quality using a PCB rather than an eyelet board? Thank you.

Hi Paul, I hope you are well my friend, haven’t seen no videos from you for a long time, hope everyone is ok 🤙🏼🇦🇺 Joe from Australia 🤙🏼🇦🇺

have you tried the serial port yet?

I am curious, what EDA software are you using?

I want to communicate with you

A wise man once said "Solder flows where solder's been, always remember tin, tin, tin". Hmmm....wonder where I might have heard that, lol.

Fnirsi is a brand of shit.

Video is old but, those tiny pads for in and out is a terrible idea. One pcb is close to 1kv, after that everything will start arching, epoxy is not gonna help, the pads are too close, the explosions would be cool though.😂
