Re: How often does an APRS DIGI need to I'd?

Just to confirm. Please never send a 10 minute DIGI id over any digi path. Send it local direct. (no hops)
If it also has a 30 minute copy then that can be sent via a single WIDE2-1 so that it can be seen in the region but less frequently. If you have a one hour beacon, then that can be a WIDE2-2 path if the local channel is not to busy, but that will cove entire states back east…
These details are buried in http://aprs.org/fix14439.html
On that page we have shown a method of using the 4 LTexts and single BText to send a local 10 minute beacon, and a regional (1 hop) 30 minute beacon. This leaves three more texts available for LOCAL frequency objects (Also sent locally, Direct (no hops) once every ten minutes. See http://aprs.org/localinfo.html
Only the digi can originate these things, because only the digi has a high sight and will only transmit this local info when the channel is truly clear so tht it does not interfere with any other packets.
Do not generate these extra objects at home. Because that location cannot hear all the channel the digi hears and will be just another hidden transmitter adding congestion on the channel.

This is what I do. My digis use meaningful callsigns with their location, and I just have it set to send an ax.25 packet with my callsign every 10 minutes. That way there’s no gray area and it follows US regs.
