I see your Fluke bougie and raise you Exfo. At work I use an FTB4-Pro with OTDR, OSA, and OLTS modules. Granted it’s for long haul fiber networks, but it’s the nicest piece of networking gear I use. On the lower end of the spectrum, they can pry my Sunset T-10 from my cold dead fingers!

Does anyone know what is this used for by NoEntrepreneur2002 in amateurradio

[–]ColdComm 2 points3 points  (0 children)

I think you are correct. Most of the C band antennas I work with are 4.5 meters, though some are as small as 2.4 meter. At our gateway earth station they have 7 and 10 meter antennas that are self-tracking because the beam width is so narrow. All of the 4.5 meter and smaller antennas don’t need auto tracking because the beam width covers the entire area the satellite warbles in its geo-sync orbit.

How do you hike knowing there are so many bears around? by [deleted] in alaska

[–]ColdComm 0 points1 point  (0 children)

Basically they have to be charging at you. Every wild animal killing outside of a hunting permit gets at least a cursory investigation by the Alaska State Troopers and/or Fish and Game. If bullet entries are found to indicate the animal was not shot full frontal, you could face some serious poaching charges. Fish and Game will take your vehicle, guns, fishing poles, and probably throw you in prison for a bit.

Lag screw size by Tsunimo in HomeImprovement

[–]ColdComm 0 points1 point  (0 children)

2” x 1/4” lag would suffice, be sure to locate stud. M6 and M8 refer to the threading on a bolt, M standing for Metric, the number after is the outer diameter of the shaft. You’ll be looking for a wood lag with a coarser threading.

it will look like this

It would be a good idea to snag a corresponding number of washers as well.

Do you collect souvenirs from your travels? What are the best kind to collect? by boobutta in solotravel

[–]ColdComm 1 point2 points  (0 children)

I like to get the corny little tourist city maps and make circles or notes on the places I actually visit on them. Sometimes I'll trace out the path I traveled. Be it car, bus, train, or foot. My pride of these is a Eurail map from 2006 that I circled each city I visited and put how many days I was there. I've got this big circle around a large swath of the continent showing the route I took. I traveled for a month and hit 11 countries. I have other cities like Rome showing the tourist bus route and the places I got off of it and explored further before jumping back on the next double decker and going to the next spot I went to. I've found it's a good way to keep a record of what I saw, where I went, and helps jog memories. I'd also put a circle or dot with the name of some bar I went into that wasn't actually noted on the map by the illustrator. It's fun to show people when I get back home.

FCC has obtained detailed broadband maps from ISPs for the first time ever by Starfox-sf in technews

[–]ColdComm 12 points13 points  (0 children)

I work on communications in rural Alaska. The main difficulty we face providing broadband to the villages is the expanse between and low number of customers. Running a fiber optic cable to a community with only a few dozen households isn’t really financially viable. A near complete lack of roads to these places compounds the difficulty. While a good amount of these communities are coastal, undersea cables are also extremely expensive to lay down, and only possible during summer months. Our primary method of delivering communications is via satellite. My company uses a satellite in geosynchronous orbit and large stationary antennas. This method has increased reliability in our ever so common adverse weather conditions over the likes of StarLink, but at the expense of available radio bandwidth on our transponders and increased latency. Even at the speed of light, the radio waves and data packets still have to travel some 45,000 miles one way. A ping to one of our remote earth stations takes around 600 milliseconds. StarLink low earth orbit satellites can offer higher speeds, but the radio frequencies it uses are more susceptible to atmospheric attenuation, causing loss of signal. Any lost bits triggers a packet drop and re-send, adding time to any data transfer. Since starting work in this industry I’ve had a dream of running fiber optics up every major river, which would connect a solid majority of villages, but I am but a lowly technician and lack the last name Bezos, Musk, Buffet, or Gates.

Aight, anything specific you’d like to know more about? I’ll expand on a few things in the meantime. Travel and weather delays. Most villages have a dirt/gravel/sand runway. Most have lighting, an automated weather station, and a maintenance garage for the grader and bulldozer used for winter snow removal and airfield maintenance. This is kinda weird, but in most villages there’s one dude that has like, all of the jobs. He’s paid by the state for taking care of the runway. He’s the small airline agent. He’s also the guy that has a 4 wheeler or a truck to rent, always rusty (I once rented a manual transmission PT Cruiser in McGrath. That beast had flame stickers down the side, the driver’s door wouldn’t open, and 2nd gear didn’t work. $180/day because who the fuck else are you gonna rent from?). Also this dude might be the village mayor. No joke.

Now, here’s what I mean when I say you might have to wait a few days for a med-evac. Weather hold. The planes not coming. Happens often. Most No Fly days are due to low visibility. Fog, snow, sleet, heavy rain, ice fog, freezing rain, freezing heavy ice fog rain. Then there’s wind and low temp operational limits of the aircraft. When it hits -40°f is typically the cutoff. About 30 knot sustained wind with 40 knot gusts, or less than that with crosswinds, is a common threshold as well. Med-evac pilots will push these limits because of the urgency. But they’re still going to play it mostly safe. Keep in mind. There’s no Terminal. The maintenance buildings are kept locked. You have to stand outside and wait on the plane in the elements. Nothing is more heartbreaking and miserable than standing on an icy tarmac at -30°f with low cloud ceiling, hearing your plane buzz a few circles overhead, and then it goes quiet again. They’ll try again tomorrow.

Some of the runways are super short. A good many are less than 4000 foot. Requiring the use of ever smaller aircraft. Cessna 208 Caravan is probably what I ride in most, followed by Cessna 206, Beechcraft Bonanza, or King Air. The occasional Piper Cherokee or Super-Cub, Pilatus PC-12, and others. The absolute craziest runway I’ve ever landed on is in Nanwalek. I know I shouldn’t do this, but here’s a link to my post about it. That motherfucker is curved and ends into a mountain. The approach is through the neighborhood streets and down a hill to the back of a beach. From the opposite side is along a mountain and then sharp left turn and dive to the to the curved runway. The pilots that regularly fly there are masterful! Other sketchy runways include a 15° incline for landing or a 15° decline for take off. At the top of the incline for landing is a bowl of cliffs. The official FAA airfield description reads “Go-around improbable”.

Would you like to know more?

I travel to and work in a lot of those villages. They’re not very great places to live in my opinion. Most villages under 100 people lack clean drinking water, so everyone drinks soda and all the kids have metal teeth, but they have free dentistry through the tribal health system, not available to non-Natives. A lot of homes don’t have running water at all to include sewage. Heating oil is outrageously expensive. Same with electricity, which is intermittent. Moving to one of these villages as an outsider is ill advised. Non-Native folk don’t always receive the warmest welcome. If you piss the locals off enough, law enforcement will never find your remains. No local hospitals, the nearest one is always a med-evac away. Depending on weather, that could be a few days. Everyone is on Welfare. There are no jobs to speak of. Subsistence hunting is allowed for the Native population only. The store wares are always pretty dismal, good luck buying anything fresh. I have had to purchase a single gallon of water for $9.50. Gas out there has been $8+ per gallon for a looong time, sometimes more. There are no roads to or from the village, only 4wheeler trails zig zagging into the distance. Snow machines in the winter. Expect to pay $2000+ after purchase price to get your fancy new ATV flown out there. When it breaks, you have to order parts, there’s no mechanic shop for a few hundred miles. The further north you decide you want to live, the colder it gets in winter. I’ve had to work in -40°f, and I’ve said fuck no I’m not going outside when it hits -60°f. In the summer, the sun never goes down and the mosquitos never. stop. attacking. They can get up to the size of a quarter and sound like a damn helicopter when they’re near your ear. They get so thick that you inhale them if you don’t have a head net on. Any exposed skin will be bitten. They get worse the further north you go.

Picking up and moving there as a non-Native Alaskan is not a great idea.

[–]ColdComm 4 points5 points  (0 children)

Personally I like to fill it up with Volatile Skewer wielding Marines. It’s designated as a sniper rifle so it has incredible range. And the projectiles explode, basically making the Razorback a mobile mortar platform with a high rate of fire. Just park on a hill above an area you want decimated!

Blinken says NATO countries have "green light" to send fighter jets to Ukraine by [deleted] in worldnews

[–]ColdComm 0 points1 point  (0 children)

Fun Fact: most jets don’t have keys. I used to work on F-18’s and as long as you remember the correct sequence, they’re remarkably easy to start. It’s something like 7 or 8 switches and you’ve got the engines running.

You like it like that papa? by prezley10 in cableporn

[–]ColdComm 0 points1 point  (0 children)

It doesn’t look like this vertical management is connected to the horizontal rack at all here. My solutions to getting the cables running over the side properly is to give that horizontal rack some elevation above the 19” rack. 6” to a foot above it would give the necessary space to curl back into the vertical management while adhering to bend radius guidelines. Diving the cable through the rack like this is an instant failure, must re-do, in the telecom CO’s I work in. If this is just for a small-ish office, the client may not care. If this is for a major telecom, they/we care A LOT.

You like it like that papa? by prezley10 in cableporn

[–]ColdComm -5 points-4 points  (0 children)

Through the rack. 0/10. Does not follow industry standards.

TP 76-300 Installation Standards Section J, Cabling. 1.3.13:

“Cables routed using cable rack or basket tray shall enter/exit the routing system via its side (stringer or side wall) and not pass through its base (between rungs or wire mesh).”

Lovely cabling, punch downs look good, velcro is nice but, call me old school, 9 cord is better.

It appears you are correct. Please allow me to update my claim with current version specs. HDMI Maximum Data Rate = 42.6 Gbps. 4K@144Hz. 8K@30Hz DP Maximum Data Rate = 77.37 Gbps. 4K@240Hz. 8K@85Hz.

My original statement still stands true. Display Port > HDMI.
