00:13:08 <electrohead> arch: https://www.ebay.com/itm/225850770521

00:13:18 <electrohead> not sure if I sent you this, or not yet
00:14:15 <electrohead> but this is the antenna I'm going to toss outside for the CB things, I'm going to test with both not grounding to earth, and then to earth
00:20:33 <arch> electrohead, let me know how that antenna works out for you
00:20:51 <arch> CB is mostly dead around here, except for the lunatics talking to themselves with a radio talk show host personality
00:21:22 <electrohead> I've already picked up some CB pirates on the car's CB radio, and that was out in my driveway lol
00:55:45 <arch> you talking about the maniacs blasting a couple kilowatts across from the west coast?
01:03:09 <electrohead> and beyond, lol
01:03:55 <electrohead> also, bonding to earth is out of the question, as these are apparently designed to use the cable as the 'ground plane' (which, of course makes sense, derp)
01:04:17 <electrohead> that said, it's all about the feed line length for proper matching
01:05:12 <arch> what about like a j-pole antenna? my 2m jpole antenna has no ground plane. works great
01:09:41 Quit: spyda ([email protected]) Ping timeout: 2 minutes
01:09:43 <arch> yea fuck cb to be honest. too much hassle. i can see why people have moven on to gmrs
01:09:50 <arch> the antenna is a fucking headache
01:10:30 <arch> electrohead, wanna exchange? can send you over my wilson 1000 antenna. you got a 1.25m radio? gotta catch em all lol
01:11:32 <electrohead> lol
01:11:45 <electrohead> I actually have a few magnetic mount antennas in storage somewhere
01:11:58 <arch> damn...so i cant bribe you =(
01:12:55 <electrohead> :P
01:14:41 <arch> electrohead, have you ever tried running a radio off an ATX PSU?
01:14:59 <electrohead> oh speaking of, I have a 2m/70cm j-pole that still needs to be put up, somewhere
01:15:13 <arch> did you check up your butt?
01:15:14 <arch> jk lol
01:15:23 <electrohead> I got that as a kit a looong time ago, using ladder line
01:15:25 <electrohead> lmao
01:15:40 <electrohead> not off an atx PSU
01:17:54 <arch> i wonder if the "switching noise spooky scary monster" thing hams complain about switching power supplies holds any weight these days
01:18:07 <arch> i mean back in the dinosaur days, switching speed was like 20-25khz
01:18:34 <arch> these days most atx psus use secondary side buck regs switching at MHz freqs even
01:19:33 <electrohead> well, I use a switching PSU in my ham rig shack thing for most things, but that's all receive only for the most part, and everything is nice and grounded/bonded
01:19:42 <electrohead> don't really notice much noise
01:20:18 <arch> good. im getting tired of hauling around a 25 lbs linear psu when i wanna mess with a mid sized radio
01:30:34 <electrohead> lmao
01:30:41 <electrohead> if anything, use filters?
01:30:58 <arch> no, we raw dogging those radiowaves
01:35:00 <electrohead> lol
01:35:26 <electrohead> I need to get more lightning arrestors for a legit proper setup
01:35:34 <electrohead> this shit gets expensive :/
01:36:02 <arch> yeah, most millenials and younger don't have money for this shit
01:37:20 <arch> not to mention electricians are expensive and hard to find
01:39:44 <electrohead> this is why I do everything myself, nowadays lol
01:44:15 <Kuschelpony> arch, the problem back then was not the switching frequency, but the bad ground routing and the reverse recovery of the diodes
01:44:25 <arch> ohh
01:46:57 <Kuschelpony> even today people still tell the religion of "stargrounding" which creates huge loops to radiate
01:48:22 <Kuschelpony> but we could make totally silent switching converters already back in the 70s, or back in the 40s if you also count mechanical choppers for tube radios
01:56:14 <electrohead> ahh, right on
01:56:29 <electrohead> I thought it was more about the switching noise
02:08:25 <electrohead> arch: if you are looking for gas discharge based lightning arrestors, use these search terms on ebay, as I have the best luck with such: "UHF Male Lightning Arrestor Socket Protector Kit For PL-259 Surge PL259"
02:11:23 * arch gives electrohead the "" look for buying critical electrical parts off ebay
02:11:50 <arch> brother for all you know, the chinese could have jizzed in that lightning arrestor and sealed it up
02:11:58 <arch> won't protect for shit
02:12:21 <rc-garage> actually.... well, how do you know that?
02:12:32 <arch> see? rc-garage got caught
02:12:46 <rc-garage> mine worked fine?
02:12:59 <rc-garage> dont know what your problem is
02:13:16 <arch> your one worked because it came (heh) from the mlp jar
02:14:39 <electrohead> > gas discharge
02:14:53 <electrohead> that's key, as these are replaceable
02:14:54 <arch> ok fine, so they farted in it and sealed it up
02:15:28 <rc-garage> add lightning, and most things turn to gas
02:16:08 <arch> yeah im basically not taking any chances with ebay/amazon electrical parts. all that shit comes from china. you dont know what kinda busbars they're using. could be stainless steel, or aluminum from soda can recycling in Chang's basement
02:16:52 <arch> in fact i did have an overheating busbar that i got from ebay, back when i was just starting out messing with PV
02:17:03 <arch> shit was too light to be "copper" busbars
02:18:58 <electrohead> replaceable, as in, source your gas discharge tubes from elsewhere? the adapters themselves can be expensive as fuck
02:19:02 <electrohead> but, I'll stop here and fuck off
02:19:21 <rc-garage> woohoo!
02:19:46 <rc-garage> remember that tomorrow is the day of the dog.

02:23:06 <electrohead> yeah I get it
02:23:15 <electrohead> I'm just trying not to light my pockets on fire :/
02:23:17 <electrohead> lol
02:23:28 <arch> lol

02:24:10 <electrohead> wasn't trying to be weird, though; it's just frustrating when protection devices are crazy stupid expensive the way it is
02:24:32 <electrohead> worst yet, legit I question where the 'proper' parts are made/sourced
02:24:39 <electrohead> fuckin' so much comes from china >.<
02:25:09 <electrohead> actually, I have two gas discharge based protection adapters, but in SMA form
02:25:14 <arch> they're all made in china. but if the company that makes them is USA based, then you have a better luck litigating against them (or rather, your home insurance company lawyers)
02:25:47 <arch> do you really think the chinese govt will let you sue against their own companies?
02:25:56 <arch> they're say fuck off lol
02:26:08 <arch> fack off and good ruck!
02:26:08 <electrohead> doing that isn't on my mind whatsoever lol
02:28:24 <arch> > can afford to spend $1200 on the latest and greatest all-band rig with waterfall display; > can't afford $100 for listed electrical surge protectors
02:28:26 <arch> seems legit
02:28:43 <arch> ham radio users *aliens meme*
02:29:30 <electrohead> lol
02:29:52 <electrohead> where did you get the $1200 from?
02:30:22 <arch> ok, ok, fine, $900. doesn't diminish my point tho
02:30:25 <electrohead> lmao
02:30:34 * electrohead diminishes arch into a potatio
02:30:38 <electrohead> potato, rather
02:30:44 * arch checks if the slow clap processor is working
02:31:23 <electrohead> lol
02:31:44 <electrohead> if you want an actual laugh, go search on amazon for 'gas discharge lightning arrestors'
02:31:57 <arch> https://www.youtube.com/watch?v=ulzFrZNAKq0
02:31:57 <EEVBot> Temporary error talking to YouTube: [SYS] unknown error (_ssl.c:2638)
02:32:26 <electrohead> there are many 'gas charge arrestors' listed, that .. are totally not gas discharge, yet they have good reviews?
02:32:31 <electrohead> I don't get it
02:33:15 <arch> you uncultured swine!
02:33:23 <arch> how could you not play Portal and Portal 2?
02:34:29 <arch> that is a highly advanced AI that got shoved into a potato by the antagonist of the game
02:34:37 <arch> well, she is also kind of an antagonist
02:34:55 <electrohead> > I don't get it
02:35:00 <electrohead> this was not to your link, lol
02:35:12 <electrohead> I've played both 1 and 2 so many times, I lost track
02:37:22 <arch> \o/

02:38:07 <electrohead> me too :/
02:38:22 <electrohead> https://0xznc01.pw:2600/public/thingggg.jpg
02:38:31 <electrohead> so, here's one of the two sma versions I have
02:38:47 <electrohead> I think these were sourced via ebay some time ago? to be honest I forget where
02:39:15 <electrohead> the shells are rugged AF
02:40:01 <electrohead> the gas discharge part on the other hand
02:40:03 <electrohead> "VACTech 090 20"
02:40:05 <electrohead> eh
02:42:49 <electrohead> I do thank you for that link though; that said, if you find a source of the gas discharge tubes themselves, please let me know as I'm still looking for a good supplier
02:43:16 <arch> you tried digikey/mouser/etc?
02:44:12 <electrohead> not yet, I'm in the middle of doing like, 10 things lol
02:47:00 <electrohead> right now I'm trying to find proper documentation on these vactech parts, out of genuine curiosity
02:48:23 <electrohead> I don't expect to find anything, lol

02:57:09 <electrohead> nice :D
02:58:57 <electrohead> hell, I could always make my own adapters for these, if I really wanted to
03:03:30 <electrohead> ahh, those are cheaper on mouser
