QUESTION, if Im doing pota with a EFHW antenna that does 10, 15, 20 and 40m.... which choke do I build? a 31 or a 43 ferrite core?
@loughkb
@loughkb 2 дня назад
Palomar engineering has a page on recommended mixes for frequency ranges. There's a table part way down the right column is wideband transformers and it looks like they would recommend a type 43 or 52. So I guess I would go with 43. palomar-engineers.com/ferrite-products/ferrite-cores/ferrite-mix-selection

Im working on the same model radio, Button press Beeps are loud and correspond with volume level, but the radio signal sound is very quiet, almost inaudible at full volume. But its there, I hear CW and Phone. Any Ideas?
@loughkb
@loughkb 5 дней назад
If you have the schematic, I'd start tracing the audio signal from the detector on through the audio amp stages until you find where it's not being amplified. Just a thought, is the squelch turned up? Oh, also, I don't remember if it has an headphones or external speaker jack, but sometimes those get dirty and don't pass the signal on to the speaker with nothing plugged in to them. Those are my guesses.

Can one use a spark plug set to a gap smaller than the plate spacing and parallel to the cap to protect it from arcing?
@loughkb
@loughkb 6 дней назад
I'd be a little more worried about the transmitter. You want to just avoid arcing in the first place because that kickback can cause extremely high spikes in SWR and possibly damage the finals on the radio. So it's best just to keep the power at safe levels.
@AlvinMcManus

Great video thanks. Now all I need is to see one on the noise that I see.
@loughkb
@loughkb 6 дней назад
Most common local noise sources are switching power supplies. Like those little wall transformers that will plug in to charge devices. If your noise is local, put your radio on a battery and turn off your breakers in the house. If the noise goes away, turn them on one at a time until the noise comes back and then you know which circuit to look at to find the noise source.

A loop is a series circuit of resistance, capacitance, inductance, so the order is irrelevant so why have the capacitor at the highest voltage point? Mine is next to the feed point, which is a gamma match. RX rated cap. Takes 100w + no flashover, it works!
@loughkb
@loughkb 7 дней назад
For the best efficiency, the coupling loop needs to be positioned where the magnetic field is the strongest, and the capacitor needs to be positioned where the electrical field is the strongest. Which are at opposite sides of the loop. I've no doubt yours works, but it is probably quite inefficient. In a good magnetic loop the bandwidth should only be about 4 to 6 kilohertz due to its very high Q. What's your bandwidth? If it's broad, it's inefficient. Which pumping high power into it would mask. I hope you're not sitting too close to the loop by the way, they create huge magnetic fields even at low powers.

except for those using the free version, then onshape owns anything you create and it's visible to others. Tinkercad is private unless you choose to make it public, I mean they still own whatever you make but at least you can hide in a see of private files I guess..

@the_str4ng3r
@the_str4ng3r 10 дней назад
Also the "tinkercad gets things a little off" issue is with copy/pasting. Its muscle memory for me to drag a solid after pasting it so it snaps to current constraints. If you don't, sometimes it will be off by anywhere from a 1/100th to 1/2 mm. So always drag/snap after paste :)
@loughkb
@loughkb 7 дней назад
Thanks, I had not noticed that. The next time I build something in tinkercad I'll remember that. Although I'm starting to play around more with free CAD, going to try to get over the learning curve so I have a nice offline solution.
@sleepib
@sleepib 10 дней назад
Sometimes it's faster to learn a new piece of software than to hack your way through in a program that isn't suitable. I'd suggest you try the new FreeCAD release candidate. The workflow would be something like this: New parametric part New sketch on XY plane. Draw a rectangle Pad the sketch fillet corners select top face, then use thickness to hollow it out. Should take about a minute to make this part. For more complicated stuff, mangojelly has a lot of good tutorials.

You left out the steps of trying to remember which of those 40 to 50 little icons does what, and all those dozens of menus. *Wink* Anything is always easiest in the program you're most familiar with. I've designed stuff in free CAD, in on shape, tinkercad, and blender. There's a lot of people that like tinkercad, they are the target audience for this video.

What if???? We attached the center conductor to a separate smaller capacitor. Would we be able to tune the coax to itself thereby increasing the coupling ability from the large loop to the small loop? Or would we kill the loop again? Then test the two caps wired together in series, and then in parallel. Just wondering.

Perfect timing, I'm just starting to get to grips with Tinkercad right now as a first foray into CAD for 3D printing! I'm thinking that I can make and save some generic boxes with lids, cylinders, connector cutouts etc that can be imported to other projects or modified for future use.
@loughkb
@loughkb 13 дней назад
Yep, I've done some of that myself. I have an SO239 and an Anderson power poles cut out up on my thingiverse page that I made in tinker. You can also add those objects to a collection called My designs in the shape selector over on the right. So if you're making something and you need to reference one of your cutouts, it's right there.

Try playing with the radius and steps controls after your box dimensions are set. You can get some very nice and interesting effects. Then punch a hole in it as shown. Have fun.
@loughkb
@loughkb 13 дней назад
Yeah the only problem though is, it universally smooths things, using all edges of the shape. You quickly lose control of dimensions, and you don't have control over any individual edge. So a box ends up rounded on the bottom. But it can be fun for making organic shapes that you're going to paste into something else.

Thanks Kevin. I was having a hell of a time with those. Coming from a cad background, I was getting really frustrated with the differences between the 2D, which I'm used to, and the 3D with it's limitations. Can't you just use the "mirror" key to complete all 4 corners? I'm so used to drawing half of something and then mirroring to complete.
@loughkb
@loughkb 14 дней назад
Yes and no. Mirror doesn't work like you're thinking it works in other CAD programs. In tinkercad you'd make a copy of the object and then use the mirror tool to flip that object to a mirror image. Then you'd have to move it into place.

Kevin, et al... For anyone interested, there is now a Maker's license of SolidWorks. I've been a SolidWorks user for almost 20 years and it is pretty intuitive. The commercial license is extremely expensive but the Maker's version is the same software package at only $48 USD/yr! I know TinkerCAD is probably free, but I would encourage you to at least look into the functionality of SolidWorks for your unique situation. Disclaimer -- I am not affiliated with SolidWorks in any way other than having been a user for many years.
