@fredix It depends on the situation. If you have few nodes and too far apart, then LONG_FAST is probably your best bet. But more and more communities are switching to MEDIUM_FAST after reaching critical mass. My theory is that the best settings will depend on too many variables (node density, buildings density, frequency, temperature, humidity, etc.), so the best settings for one region may not be the best for another.

Chatting with ppl on the mesh from 41k ft is amazing. Talking about chess, meteors, and tray tables. So much fun. Utilized over 45% during flight to JFK.

@djh @finn Oh, that changes everything. This is excellent info! I assume that MeshCore's TX settings mentioned in the thread are in dBm (and not an arbitrary unit), right?

@finn Yes, multimeters are usually slow. I'm using a bench power supply whose ampmeter is a bit faster. But maybe (certainly) an oscilloscope would be more appropriate.

I'll try another capacitor when I have the chance. Maybe I was just unlucky (or my Heltec unit has an entirely different issue 😅).

@finn What a coincidence! I'm trying to tackle this very issue right now. My #heltecv4 reboots on TX if the battery is under 3.7V and power is set to 22 dBm+.

I tried to insert a 1000uF cap just like you did, but it didn't work. I measured the voltage sag and it takes way longer to recover to baseline, whereas the capacitor can handle it just for a fraction of a second.

I wonder what I'm doing wrong... My temp solution was reducing TX power, which negates the only advantage of having a V4 😮‍💨

Nos juntamos para una jornada #Meshtastic al aire libre en el parque de la Facultad de Agronomía.

Vamos a activar el nodo “La Pera Zombie” compartiendo ubicación exacta por GPS, así que queda lanzado el desafío: ¡encontrar al grupo usando la geolocalización! 🛰️

Because mastodon is like a 99% male audience, I will say this: if you have an aging mother you are in relationship with and care about, do NOT make her go through medical stuff alone. I am skilled & mean enough to fight through medical stuff and even so you would not believe how bad it is. Just accept that you cannot imagine.

I talk to a lot of people's aging moms and they are abandoned & alone even in nice families. I don't care how awkward it is, you have to try to ask them about it.

In August 2025, #Google announced ↗ that as of September 2026, it will no longer be possible to develop apps for the #Android platform without first registering centrally with Google.

Today I moved https://lcwo.net/ (Learn CW Online) to a new home.

It was living on a shared hosting platform since 2008, but with the steady growth of users, I had to move on. The previous hosting (randonly?) blocked IP ranges when the server load grew too high. Not acceptable.

So I commissioned a new, beefy VPS for all of my ham radio projects and LCWO is now running smoothly on it. 82 users are logged in right now, the system load average is 0.2.

Hi Folks! I'm Erica and although I'm not new to mastodon in general, I am new to mastodon.radio. I wanted to establish a home to post stuff specific to Ham Radio and occasionally retro electronics. I'm most active on CW and the Digital modes with most of my focus on VHF and Satellite at the moment. Great to meet you all!
