Youre a boss! I was wondering if I had got a basic 390 instead of a 390Plus since universal wasn't applying. Now it works perfectly! Thank you!!!!

Bro got a gaming setup 😀😀😀

In the 2.41 version on the channel info screen there is a space titled message format where you can select either M format or DMR format. What is this for? This was not included in the previous version.

It was called RF Skip

You can brick a radio and permanently stop its function? That’s a hefty price to pay. I want to learn and get into Harris I think they are better than Motorola IMO. Great video!

Great vid

Beg to differ, software and firmware IS available on li ne..

Just bought the Ailunce ham radio DMR great little radio

The view at :40 is beautifull

Just ordered one from ol Rick in Humboldt. Its out for delivery for tomorrow!

I'm seriously dizzy I can't watch this The camera work is terrible

Pls tell us how is this machine preforming so far ?… I suffer from all kind of allergy … thank you 🙏🏻

Great job love the Linux boot up

Yo

Great video! Incredibly informative and super interesting! Can you talk a little about how these sites are monitored remotely? Is it a site to site vpn with something like SNMP or more proprietary protocols? Thanks! Subbed and joined the discord!

That antenna is a pretty advanced phased array. Beam forming. The way the DC-DC converter can find the correct input voltage for the desired output voltage is by monitoring its output voltage and current. It can figure out how much loss is involved and calculate the correct compensation voltage.

Nice video! How did you get into the field? I think I'd enjoy this as a job.

I have seen HDMI on dell and nether switches to stack them. Now I know it happens on even bigger equipment, crazy. Amazing vid!!!

T-Mo has nationwide 600MHz on band 71

Amazing how advanced some of our modern telecom infrastructure is. The old clicky automatic switches have a special place in my heart though.

Whats the power output of the TX?

Does the cellsite connect to a netowork cordinator some where to validate the subscriber etc. I assume all interconnction is done by IP now?

I'm pretty sure the GPS signal isn't for locating the tower. That can be hard coded. I'm pretty sure that the GPS signal is used as a time base for Timing Advance.

very awesome video, cell sites are fascinating and genius the way they work

A couple VZW sites by me have their feedlines go through a pipe before going in the shelter. My only thought would be a choke for lightning??

One carrier doesn't even have batteries at a site by me. Their other site has a new diesel generator that has had a fault code for months and doesn't run when the power is out.

Great video!! I recently had the opportunity to spend the day at a large Verizon cellular switching office based in SE Michigan.. Security was super tight.. Definitely no pictures.. Each floor of the building held different radio equipment for the various bands.. 2g-3g-4g-5g .. one complete floor for hundreds of batteries. I looked at the COW's on site, drones they use and a mobile cell CO in the back of a huge trailer-truck with satellite dishes mounted on top. The 8 or so ac units, a hook up for a diesel fuel tanker to provide fuel for the 8 or so generators in case electrical system failed. Then the main command center staffed 24-7 showing ALL VZ sites in the State displayed on huge monitors and they had various colors to them for troubles or other. Plus a huge weather radar screens as well. Once in a lifetime experience. Would like to know what are the top 5 issues that break or fail at any one tower site?

Watched every second, great job!!

Love this stuff... I still want to be a cell site auditor somehow. I wouldn't mind traveling around central texas to inspect cell sites and get paid for it.

I would love to read that ATT handbook of norms and standards. How can I get a hold of one of those?

so neat

In France, we dont really use DMR for public safety, we use Tetra, DMR is only for businesses or in some very specific cases special forces might use some with AES encryption

very interesting and informative! why still use the wax string vs. cable ties?

Hi, Have any of the cell companies implemented any EMP proofing the cell site equipment?

When you have to climb a tower I imagine you have to Lock Out Tag Out the equipment in the base building / shelter. Is it just the DC bus feeding up the tower that has to be secured? Or do you also have to secure the fiber lines somehow?

What is the store where everyone busy? Long lines wherever you see Everyone knows it's Safeway

it is IP-67 , U can be sure

Amazing still working, I still remember the sound of the diferents types of rings for the central offices before the modern standard ring came out

That's incredible! Really awesome stuff here for Halloween season

Verry Cool

Great Video

Thanks for the heads up

You wouldne amazed at how many of these sites are still active, in a ready state to return to service and how they have been updated and kept updated. The security for those is very impressive. And as some have said it is not going to be possible to video within any of these that still has equipment. Those who try to enter are dealt with extremely harshly.

Cool video.

Thank you

I assume your a contractor, But I wonder if AT&T is aware that you're filming a site of theirs!

I love to own one and make it into a home that will be cool

Where’s your fishing pole? 😂

I heard the CPS license is really expensive. True?
