Great show with Ziggy again ! AWG is American Wire Gauge. Some great wire on the show. I use the DX commander DX 50 wire for good dipoles, has Kevlar core. does not stretch much at all if any. I made my one power cord for IC 7300. you can buy that 4 pin plug. I made with all 10 AWG OFC wire. I did the parralo splice near plug like the icom one. but all 10 wire. then close to that plug ,I tool a FT 240-31 ferrite core . 31 mix and wrapp 10 turns threw it. that a common mode choke. then a short run into 2- 10 AWG fuse holders. They came in red so I put place heat shrink on one. Then the 45 AMP power poles. I get less voltage drop on the display then the icom cable . At my radio station we had a direct strike from lightning. at one of the 4 towers, Blue out the second down tower light. had to notify FAA on that. The end of the feed line where it cupples to tower blew a burned hole an end of copper feedline. That soloed copper. and Nitrogen filled line. The transmitter had no damage . but station off the air due to feed line. had to switch to back up transmitter and feed line . Lots of paperwork . FCC and FAA. and this during winter Blizzard in NY. 4 ft of snow ,60 Mph winds. All bets are off with Lightning . and all Lightning not the same. different power levels and can change polarly. NOAA taught me about positive lightning. 73
The laughs on this cast are better than any slick silicone wire thanks guys 😂 always great
Thanks again for the drawing last week ! Was great to win.
Lightening is a honey badger. It DGaF as long as there's metal nearby.
There's a reason fuses (break on over current) are super common and crowbar circuits aren't. Current burns down buildings. Voltage just fries sensitive hardware.
Jim needs a new lawn mower guy; or require him to mow when he's sober!
Exactly right
I like how this turned into a stealth cat video
My son loves his kitten, I let him slide in every once in awhile, thanks for watching!
@@75ohmHAM people are going to be offended by ape's accepting review samples and follow his advice to go watch a cat video and end up in an infinite loop XD
Great show, fellas. #TeamReplay
Question for Ziggy. You used a hook that you mentioned you used for wrapping toroids. I use heavier wire and struggle getting it tight. It looks like you have a system for doing that. Would love to see a video on how you use your setup to wire tolroids tight.
12AWG is 4 mm2
“Shall be no smaller than 14ga”
👀
I guess my 22ga stealth wire is out of spec…
Flex seal is horrible on anything that moves. It's super fragile.
If I were building a Power Cart, and wanted to install an insulated power buss, how well would a pair of 1/2 copper pipes do for the buss assuming that it will be installed in a manner that nothing other than the connections will be able to come into contact with it? For Rat deterrent, go to your favorite hunting/outdoors man store and find the fox urine lure, every week or so use an eyedropper and drop several drops around the engine bay.
I would strongly recommend using a fused distro block, you're not gaining anything but the ability to accidently set your cart on fire having large exposed "terminals" just look up fused distro box

Why haven’t I jumped in my _DeLorean_ and gone back to when copper was a lot cheaper and bought a few hundred feet of *_”wahr”?_* Oh, yeah … _Digikey_ and _Mouser_ don’t stock *FLUX CAPACITORS* …😀
I used to work for an electrical contractor and _”THHN”_ was his favorite. The insulation was a lot more _”slippery”_ and easier to pull through a conduit. Also (at least back then) it was certified as _”plenum wire”_ due to its 105° temperature rating.
As for the _”tinned copper”,_*skin effect* is *NOT* your friend (for *antenna* use). *CCA* _(copper clad aluminum)_ is better. For DC use, it’s just the opposite.

Should have loaded up back in the day 🤨
For a 6ah battery connected to a qmx should i use 14awg? Or will the 18awg work?
Sometimes knowing how to ask the question is the key.. here friend..
For a 3-foot wire carrying 12V at 1 amp, you can use a fairly small gauge wire since the current is relatively low and the distance is short. Here's a brief calculation:
1. **Current Capacity**: According to the American Wire Gauge (AWG) standards, a 24 AWG wire can handle up to 2 amps, which is sufficient for your 1 amp requirement.
2. **Voltage Drop**: The voltage drop over a short distance of 3 feet is minimal. For 24 AWG wire, the resistance is approximately 0.02567 ohms per foot. For 3 feet, the total resistance is:
\[
R = 0.02567 \, \Omega/\text{ft} \times 3 \, \text{ft} = 0.07701 \, \Omega
\]
The voltage drop \( V \) is given by Ohm's law \( V = I \times R \):
\[
V = 1 \, \text{A} \times 0.07701 \, \Omega = 0.07701 \, \text{V}
\]
This voltage drop is negligible for a 12V system.
Given these considerations, a 24 AWG wire should be adequate for your application. If you want to ensure even lower voltage drop and better mechanical strength, you could opt for a slightly thicker wire, like 22 AWG or 20 AWG.
I wouldn't go lower than 18 bro, more for strength
