I think it would be a good idea to not require forms, but the opportunity to practice with forms is a good one.

BTW: In my ARES group (City of Bellevue WA BCS), ICS-213RR is the heavy hitter form

LoRa is a PHY layer. It supports many different protocols on top.

Here are a few examples:
LoRaWAN
Meshtastic
Meshcore
Reticulum
OuterNet - LoRa from a GEO satellite (35,786 km)
TinyGS - LoRa from LEO cubesats.

Regarding the evolution of #APRS, I agree that the AX.25 over-the-air protocol impose constraints on both AfskAPRS and LoRaAPRS. And, yes, this involves digipeating as you point out.

However, those constraints don't impose anything in the APRS-IS network core. iGate are part of the APRS-IS network. SSIDs on APRS-IS are just a dash and a string appended to a callsign — they don't have to be numeric at all, let alone 0–15

@Aegewsh
I was on packet radio using @AX25 on a TAPR TNC and an ADDS Video Terminal in the early 1980's before Bob Bruninga came along. #APRS created many one-way devices such as the tracker that I had for a long time. It just transmitted. Many of the devices that came along were incompaticle with the very intent of the AX.25 protocol.

Yes, I used to be very active on many LoRa projects, incuding Peter Buchegger's telegram group in German.

@Aegewsh
100% AX.25 Packet radio was invented in 1978's after I got my HAM license 50 years ago.

It was a point-to point network with digipeaters in the middle. The first TNCs were designed by #TAPR in 1983.

Bob Bruninga took AX.25 packet and confined it to mostly a weather station and GPS tracker protocol (on the left).

#LoRaAPRS was the initial work of Peter Buchegger OE5BPA, Bernd Gasser OE1ACM, Christoph Gasser OE1CGC and Christian Johan Bauer OE3CJB. That's the vision on the right.

Bud,
I responded to the #FFWN question of the day via #VARA-FM. West side of Denver really needs another RMS.

I think your upcoming questions could help #Winlink users learn to use forms. Some good ones are GPS position report, quick message or Winlink Check-in under general templates.

Knowing how to use forms can help train casual users of Winlink to be of valuable assistance during an emergency. Often there are not enough people available.

Stetryczaly, I'm curious. How formal is your #LoRaAPRS development? Did you write a Systems Requirements Document and a Systems Design Document? Or is this an Agile project where the architecture and software just evolve?

@rocking_horse #Reticulum seems to be non-ham radio protocol. It's purpose is to send traffic over all sorts of different PHY layers. It's distributed and encrypted. There are more #preppers than there are HAMs

#LoRaWAN is an unlicensed IT protocol maintained by the LoRa Alliance. Not #HAM radio

#LoRaAPRS originated in Austria. I helped translate German documentation into English and Spanish to bring it to ITU region 2. It's more wide-spread in Spanish speaking countries than the US.

@Aegewsh

Again. LoRaAPRS and (AFSK)APRS are over the air AX.11 protocols. AX.11 packet already in the early 1980's before Bob Bruninga ever decided to trademark APRS.

The protocol from the iGate to the APRS core is not limited by the ancient AX.11 standard and doesn't follow it.

iGates are not destinations or endpoints. They just pass radio traffic. This is why the SSIDs can be literally anything.

@bud_t @KC8JC

#FFWN .. Did you update the question on your page yet? I checked in early last night. No question.
