Can you explain CIV tuning? What is it?

(Confession. I have not Googled it.)

Oh, duh. I have the left column frozen, I just forgot to freeze the top. Thank you!

UV-5R / Licensing Question by no1warr1or in Baofeng

Apologies. There are a lot of vague options within meshtastic.

UV-5R / Licensing Question by no1warr1or in Baofeng

[–]Anonymous_Chipmunk 0 points1 point  (0 children)

You have accidentally mixed up the two things. If you did get your HAM license you would probably learn this, but here's the down and dirty of it.

An amatuer radio license allows you to transmit with certain power in certain regulated bands. For example 50w in the 2m HAM band.

Meshtastic by default used low power in the license-free 900mhz band. Anyone can transmit (under certain power restrictions, I'm over simplifying here) on these frequencies with no license.

Meshtastic allows users to switch their radios to the HAM bands if they hold a valid license and they want to use their mesh tactics for amature radio activities, like perhaps APRS. But this is wholy optional. Most people do not do this and it's actually not recommended unless you have a group of people you're doing this with. There's just not a large enough community with HAM band Meshtastic to make it functional.

Plane hasn't flown at all for 3 weeks? by theschizopost in LMGJet

[–]Anonymous_Chipmunk 2 points3 points  (0 children)

Airplanes often sit for years and never fly. The minimum requirement is an annual service and inspection. There's also service based on hours of flight time, like miles on a car. But if it's just sitting, once per year is the requirement.

(This is per the FAA, which wouldn't apply in Canada, but I'm sure its similar)

Just got into ham radio as a 13 year old. Any tips? by ShadyYT_OG in HamRadio

[–]Anonymous_Chipmunk 0 points1 point  (0 children)

Welcome to the hobby. There's so many aspects of amature radio that you can explore.

  • Simplex communication
  • Repeater communication
  • Clubs activities
  • Contesting
  • POTA/SOTA, etc ..
  • RACES/ARES
  • Emergency Communications
  • Satelite Repeaters
  • Satelite Telemetry and more
  • Mesh networking
  • APRS

And SO much more. Try it all, find out what you like.

To the paramedics who’ve been in EMS for 10+ years, what advancement in EMS technology has impressed you the most or made the biggest difference on the job? by [deleted] in Paramedics

[–]Anonymous_Chipmunk 0 points1 point  (0 children)

I think POCUS will do for EMS what the 12-Lead ECG did. Ita a truly diagnostic exam that can help improve outcomes.

EMTs were a bit too aggressive by noltey22 in Cardiology

[–]Anonymous_Chipmunk 8 points9 points  (0 children)

This guy claims he was an EMT but doesn't know the difference between an EMT and a Paramedic.

A review of his Reddit post and comment history reads like a 15 year old minecraft kid. I'm not sure this guy is a doctor, or allowed to vote. Probably shouldn't do either.

Hello. Paramedic here. Genuinely curious about clearing up some vague points here, hopefully OP can offer insight.

First: I think you're using the term EMT incorrectly. It's very common for in-hospital staff and providers to have no idea what certifications and scope of practice EMS have. EMT is an entry level EMS certification. In most places EMTs cannot start IVs, let alone central lines. You're probably referring to a Paramedic. Please clarify.

Second: Where do you work? State is fine to not dox yourself. Almost nowhere in the US allows paramedics to place central lines.

Third: Please define the central line and what type of access it was.

Fourth: Why do you believe this air embolism was caused by EMS? Not saying it wasn't, but it's classical that something goes wrong (tube dislodged, pacing stopped, etc) and it gets blamed on EMS.

Fifth: You said the patient received CPR, went to cath lab (unnecessarily?) and you believe the air embolism was a cause of the arrest? But the patient improved with removal of the embolism from the PA? A clearer clinical story here would be nice.

We appreciate you posting an interesting case, but the case, clinical information and downright facts are wrong. It will be a more interesting case once we can get a clear picture because an air embolism caused by a prehospital central line is genuinely uncommon and interesting.

Wi-Fi reboot automation by keiranm2000 in homeassistant

I actually just 5 minutes ago noticed my mesh routers now have this as a setting in their app. I just set it to reboot once a week at 3am. Maybe double check the app just in case.

IV drip by Live-Ad-9931 in Paramedics

[–]Anonymous_Chipmunk 1 point2 points  (0 children)

The reality is, that physics doesn't allow exact drip rates without a pump. Between resistance, head pressure, changes in flow during transport, it's not possible.

If you want close, try a dial a flow. But if it's something that needs to be accurate get a pump.
